 # Eiblog Changelog

+## v1.3.0 (2017-07-13)
+* 更改 app.yml 配置项，将大部分配置归在 general 常规配置下。注意，部署时请先更新 app.yml。
+* 静态文件采用动态渲染，即用户不再需要管理 view、static 目录。
+* 通过 acme.sh 使用双证书啦，可到 Makefile 查看相关信息。
+* 使用 autocert 自动生成证书功能，从此再也不用担心证书过期，移步 [证书更新](https://github.com/eiblog/eiblog/blob/master/docs/autocert.md)。
+* 开启配置项 enablehttps， 将自动重定向 http 到 https 啦。

+  * `CDN`，使用七牛融合CDN，并 `https` 化，实现全站 `https`。七牛可申请免费证书了。
  * `CT`，证书透明度检测，提供一个开放的审计和监控系统。可以让任何域名所有者或者 CA 确定证书是否被错误签发或者被恶意使用，从而提高 HTTPS 网站的安全性。
  * `OSCP`，在线证书状态协议。用来检验证书合法性的在线查询服务.
  * `HSTS`，强制客户端（如浏览器）使用 HTTPS 与服务器创建连接。可以很好的解决 HTTPS 降级攻击。
-  * `HPKP`，HTTP公钥固定扩展，防范由「伪造或不正当手段获得网站证书」造成的中间人攻击。该功能让我们选择信任哪些`CA`。
-  * `SSL Protocols`，罗列支持的`TLS`协议，SSLv3被证实是不安全的。

+### 证书自动更新
+
+本博客证书自动更新有两种方式：
+
+* [acme/autocert](https://github.com/golang/crypto/tree/master/acme/autocert)，博客内部集成，通过 tls-sni 验证，实现全自动更新证书，一键开启关闭。请在裸服务器的情况下使用（不要使用代理）。单证书
+* [acme.sh](https://github.com/Neilpang/acme.sh)，强大的 acme 脚本，多种自动更新证书方式，满足你各方面的需求。双证书
+
+#### 方式一
+什么是 autocert，简单点，你只需要两步操作：
+
+1. 将域名解析到你的服务器。
+2. 在服务器上运行开启 autocert 功能的程序（这里不需要配置证书），需要占用 443 端口。
+
+其它过程你不需要过问，即会完成自动申请证书，自动更新证书的功能（默认 30 天）。这个是在 tcp/ip 层的操作，对用户完全透明，非常棒。
+
+一键开启 autocert 功能，只需修改 `conf/app.yml` 文件内容：
+
+```
+# 运行模式
+mode:
+  # http server
+  enablehttp: true
+  httpport: 9000
+  # https server
+  enablehttps: true                     # 必须开启
+  autocert: false                       # autocert 功能开关
+  httpsport: 9001
+  certfile: 
+  keyfile: 
+  domain: deepzz.com                    # 申请证书的域名，也是博客的域名
+```
+
+首先，使用 HTTPS 必须启用  `enablehttps`，它有两个作用：
+
+* 如果 `enablehttp` 开启，会自动 301 重定向到 https。
+* 作为开启 autocert 的前提条件。
+
+其次， `autocert` 是否开启也有两个作用：
+
+* false，服务器将使用 `httpsport`、`certfile`、`keyfile` 作为参数启动 https 服务器。
+* true，服务器直接使用 443 端口启动 https 服务器，并且自动申请证书，且在证书只有 30 天有效期时自动更新证书。域名为 *运行模式* 下的 mode->domain。
+
+#### 方式二
+
+使用方式二，你需要了解 acme.sh 的具体使用方式，非常简单。选择适合自己的方式实现自动更新证书。
+
+博主，这里实现了 aliyun dns 的自动验证，自动更新证书。详情参见 Makefile->gencert。这里实现了自动申请 ecc、rsa 双证书，并且自动申请 scts，自动安装，自动更新。
+
+基本流程如下：
+
+1. 创建相关目录：`/data/eiblog/conf/ssl`、`/data/eiblog/conf/scts/rsa`、`/data/eiblog/conf/scts/ecc`。
+2. 自动下载安装 acme.sh 脚本。
+3. 自动申请 RSA 证书并且自动获取 scts，并且自动安装到指定位置。
+4. 自动申请 ECC 证书并且自动获取 scts，并且自动安装到指定位置。
+
+##### 使用方式
+
+导出环境变量，Aliyun dns 的环境变量为：
+
+```
+export Ali_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
+export Ali_Secret="jlsdflanljkljlfdsaklkjflsa"
+```
+
+执行命令：
+
+```
+$ make gencert -cn=common_name -sans="-d example.com  -d example1.com"
+```

+1. pull 镜像  `docker pull elasticsearch:2.4.1`。

-  ```
-  conf/es/config:/usr/share/elasticsearch/config
-  conf/es/plugins:/usr/share/elasticsearch/plugins
-  conf/es/data:/usr/share/elasticsearch/data
-  conf/es/logs:/usr/share/elasticsearch/logs
-  ```
-  请将这四个目录映射至`eiblog`下的`conf`目录。如果你想查看更多，请查看`docker-compose.yml`文件。

 #### 前提准备
 这里需要准备一些必要的东西，如果你已准备好。请跳过。

 * `一台服务器`。
 * `一个域名`，国内服务器需备案。
-* `有效的证书`。一般使用免费的就可以。如：`Let‘s Encrypt`，另外`qcloud`、`七牛`也提供了免费证书的申请，均是全球可信。
-* `七牛CDN`。博客只设计接入了七牛cdn，相信该CDN服务商不会让你失望。
-* `Disqus`。作为博客评论系统，你得有翻墙的能力注册到该账号，具体配置我想又可以写一片博客了。简单说需要`shorname`和`public key`。
+* `有效的证书`。通过开启 autocert 可自动申请更新证书。也可去七牛、qcloud 申请一年有效证书。

 是不是这么多要求，很费解。其实当初该博客系统只是为个人而设计的，是自己心中想要的那一款。博主些这篇文章不是想要多少人来用该博客，而是希望对那些追求至极的朋友说：你需要这款博客系统。
 #### 文件准备
-尽管大多数文件已经准备好。但有些默认的文件需要特别指出来，需要你在 CDN 上写特殊的路径。
+博主是一个有强迫症的人，一些文件的路径我使用了固定的路径，请大家见谅。假如你的 cdn 域名为 `st.example.com`，你需要确定这些文件已经在你的 cdn 中，它们路径分别是：

-假如你的 CDN 域名为`st.example.com`，那么：
+| 文件                 | 地址                                       | 描述                                       |
+| ------------------ | ---------------------------------------- | ---------------------------------------- |
+| favicon.ico        | st.example.com/static/img/favicon.ico    | cdn 中的文件名为 `static/img/favicon.ico`。你也可以复制 favicon.ico 到 static 文件夹下，通过 example.com/favicon.ico 也是能够访问到。docker 用户可能需要重新打包镜像。 |
+| bg04.jpg           | st.example.com/static/img/bg04.jpg       | 首页左侧的大背景图，需要更名请到 views/st_blog.css 修改。   |
+| avatar.jpg         | st.example.com/static/img/avatar.jpg     | 头像                                       |
+| blank.gif          | st.example.com/static/img/blank.gif      | 空白图片，[下载](https://st.deepzz.com/static/img/blank.gif) |
+| default_avatar.png | st.example.com/static/img/default_avatar.png | disqus 默认图片，[下载](https://st.deepzz.com/static/img/default_avatar.png) |
+| disqus.js          | st.example.com/static/js/disqus_xxx.js   | disqus 文件，你可以通过 https://short_name.disqus.com/embed.js 下载你的专属文件，并上传到七牛。更新配置文件 app.yml。 |

-* `favicon.ico`，其 URL 应该是`st.example.com/static/img/favicon.ico`。故你在 CDN 中的文件名为`static/img/favicon.ico`，以下如是。
-* `左侧背景图片`，`500*1200`左右，CDN 中文件名：`static/img/bg04.jpg`。如需更改，请在`eiblog/view/st_blog.css`中替换该名称。
-* `头像`，`160*160~256*256`之间，CDN 文件名：`static/img/avatar.jpg`。另外你需要将该图片 `Base64` 编码后替换掉`eiblog/views/st_blog.css`中合适位置的图片。
-* `blank.gif`，CDN 文件名：`static/img/blank.gif`。该图片请从[这里](https://st.deepzz.com/static/img/blank.gif)下载并上传至你的 CDN。
-* `default_avatar.png`，CDN 文件名：`static/img/default_avatar.png`，请从[这里](https://st.deepzz.com/static/img/default_avatar.png)下载并上传至你的 CDN。
-* `disqus.js`，该文件名是会变的，每次更新如果没有提及就没有改变，更新说明在[这里](https://github.com/eiblog/eiblog/blob/master/CHANGELOG.md)。CDN 文件名格式是：`static/js/name.js`。在我写这篇文章是使用的是：`static/js/disqus_a9d3fd.js`，请从[这里](https://st.deepzz.com/static/js/disqus_a9d3fd.js)下载并上传至你的 CDN。
-
-> `注意`：本人 CDN 做了防盗链处理，故请将这些资源上传至您的 CDN ，以免静态资源不能访问，请悉知。
+> 注意：每次修改 views 内的以 `st_` 开头的文件，请将 `app.yml` 中的 staticversion 提高一个版本。 cdn 提到的文件下载，请复制链接进行下载，因为博主使用了防盗链功能。

+Go-spew implements a deep pretty printer for Go data structures to aid in
+debugging.  A comprehensive suite of tests with 100% test coverage is provided
+to ensure proper functionality.  See `test_coverage.txt` for the gocov coverage
+report.  Go-spew is licensed under the liberal ISC license, so it may be used in
+open source or commercial projects.
+
+If you're interested in reading about how this package came to life and some
+of the challenges involved in providing a deep pretty printer, there is a blog
+post about it
+[here](https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).

+http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
+
+## Installation
+
+```bash
+$ go get -u github.com/davecgh/go-spew/spew
+```
+
+## Quick Start
+
+Add this import line to the file you're working in:
+
+```Go
+import "github.com/davecgh/go-spew/spew"
+```
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+
+```Go
+spew.Dump(myVar1, myVar2, ...)
+spew.Fdump(someWriter, myVar1, myVar2, ...)
+str := spew.Sdump(myVar1, myVar2, ...)
+```
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
+compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
+and pointer addresses): 
+
+```Go
+spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+```
+
+## Debugging a Web Application Example
+
+Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
+
+```Go
+package main
+
+import (
+    "fmt"
+    "html"
+    "net/http"
+
+    "github.com/davecgh/go-spew/spew"
+)
+
+func handler(w http.ResponseWriter, r *http.Request) {
+    w.Header().Set("Content-Type", "text/html")
+    fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
+    fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
+}
+
+func main() {
+    http.HandleFunc("/", handler)
+    http.ListenAndServe(":8080", nil)
+}
+```
+
+## Sample Dump Output
+
+```
+(main.Foo) {
+ unexportedField: (*main.Bar)(0xf84002e210)({
+  flag: (main.Flag) flagTwo,
+  data: (uintptr) <nil>
+ }),
+ ExportedField: (map[interface {}]interface {}) {
+  (string) "one": (bool) true
+ }
+}
+([]uint8) {
+ 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+ 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+ 00000020  31 32                                             |12|
+}
+```
+
+## Sample Formatter Output
+
+Double pointer to a uint8:
+```
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+```
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+```
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+```
+
+## Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available via the
+spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the ConfigState documentation for more details.
+
+```
+* Indent
+	String to use for each indentation level for Dump functions.
+	It is a single space by default.  A popular alternative is "\t".
+
+* MaxDepth
+	Maximum number of levels to descend into nested data structures.
+	There is no limit by default.
+
+* DisableMethods
+	Disables invocation of error and Stringer interface methods.
+	Method invocation is enabled by default.
+
+* DisablePointerMethods
+	Disables invocation of error and Stringer interface methods on types
+	which only accept pointer receivers from non-pointer variables.  This option
+	relies on access to the unsafe package, so it will not have any effect when
+	running in environments without access to the unsafe package such as Google
+	App Engine or with the "disableunsafe" build tag specified.
+	Pointer method invocation is enabled by default.
+
+* ContinueOnMethod
+	Enables recursion into types after invoking error and Stringer interface
+	methods. Recursion after method invocation is disabled by default.
+
+* SortKeys
+	Specifies map keys should be sorted before being printed. Use
+	this to have a more deterministic, diffable output.  Note that
+	only native types (bool, int, uint, floats, uintptr and string)
+	and types which implement error or Stringer interfaces are supported,
+	with other types sorted according to the reflect.Value.String() output
+	which guarantees display stability.  Natural map order is used by
+	default.
+
+* SpewKeys
+	SpewKeys specifies that, as a last resort attempt, map keys should be
+	spewed to strings and sorted by those strings.  This is only considered
+	if SortKeys is true.
+
+```
+
+## Unsafe Package Dependency
+
+This package relies on the unsafe package to perform some of the more advanced
+features, however it also supports a "limited" mode which allows it to work in
+environments where the unsafe package is not available.  By default, it will
+operate in this mode on Google App Engine.  The "disableunsafe" build tag may
+also be specified to force the package to build without using the unsafe
+package.

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+	* Pointers are dereferenced and followed
+	* Circular data structures are detected and handled properly
+	* Custom Stringer/error interfaces are optionally invoked, including
+	  on unexported types
+	* Custom types which only implement the Stringer/error interfaces via
+	  a pointer receiver are optionally invoked when passing non-pointer
+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output (only when using
+	  Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+	* Dump style which prints with newlines, customizable indentation,
+	  and additional debug information such as types and all pointer addresses
+	  used to indirect to the final value
+	* A custom Formatter interface that integrates cleanly with the standard fmt
+	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+	  similar to the default %v while providing the additional functionality
+	  outlined above and passing unsupported format verbs such as %x and %q
+	  along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew.  See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+	spew.Dump(myVar1, myVar2, ...)
+	spew.Fdump(someWriter, myVar1, myVar2, ...)
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type.  For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions.  This allows concurrent configuration
+options.  See the ConfigState documentation for more details.
+
+The following configuration options are available:
+	* Indent
+		String to use for each indentation level for Dump functions.
+		It is a single space by default.  A popular alternative is "\t".
+
+	* MaxDepth
+		Maximum number of levels to descend into nested data structures.
+		There is no limit by default.
+
+	* DisableMethods
+		Disables invocation of error and Stringer interface methods.
+		Method invocation is enabled by default.
+
+	* DisablePointerMethods
+		Disables invocation of error and Stringer interface methods on types
+		which only accept pointer receivers from non-pointer variables.
+		Pointer method invocation is enabled by default.
+
+	* ContinueOnMethod
+		Enables recursion into types after invoking error and Stringer interface
+		methods. Recursion after method invocation is disabled by default.
+
+	* SortKeys
+		Specifies map keys should be sorted before being printed. Use
+		this to have a more deterministic, diffable output.  Note that
+		only native types (bool, int, uint, floats, uintptr and string)
+		and types which implement error or Stringer interfaces are
+		supported with other types sorted according to the
+		reflect.Value.String() output which guarantees display
+		stability.  Natural map order is used by default.
+
+	* SpewKeys
+		Specifies that, as a last resort attempt, map keys should be
+		spewed to strings and sorted by those strings.  This is only
+		considered if SortKeys is true.
+
+Dump Usage
+
+Simply call spew.Dump with a list of variables you want to dump:
+
+	spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer.  For example, to dump to standard error:
+
+	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+	(main.Foo) {
+	 unexportedField: (*main.Bar)(0xf84002e210)({
+	  flag: (main.Flag) flagTwo,
+	  data: (uintptr) <nil>
+	 }),
+	 ExportedField: (map[interface {}]interface {}) (len=1) {
+	  (string) (len=3) "one": (bool) true
+	 }
+	}
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.
+	([]uint8) (len=32 cap=32) {
+	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+	 00000020  31 32                                             |12|
+	}
+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
+functions have syntax you are most likely already familiar with:
+
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Println(myVar, myVar2)
+	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output.  Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+	  a pointer receiver are optionally invoked when passing non-pointer
+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output
+
+The configuration options are controlled by an exported package global,
+spew.Config.  See ConfigState for options documentation.
+
+See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
+get the formatted result as a string.

+printing functions.  The formatter is useful for inline printing of smaller data
+types similar to the standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Typically this function shouldn't be called directly.  It is much easier to make
+use of the custom formatter by calling one of the convenience functions such as
+Printf, Println, or Fprintf.

+```
+
+#### Print Level
+```
+Ldebug        = 1 << iota //
+Linfo                     //
+Lwarn                     //
+Lerror                    //
+Lfatal                    //
+
+logd.Printf()
+logd.Print()
+logd.Debugf()
+logd.Debug()
+logd.Infof()
+logd.Info()
+logd.Warnf()
+logd.Warn()
+logd.Errorf()
+logd.Error()
+logd.Fatalf()
+logd.Fatal()
+```
+5种日志等级，12种打印方法，完全理解你记录日志的需求。
+
+```
+Ldebug < Linfo < Lwarn < Lerror < Lfatal
+```
+通过`SetLevel()`方法设置，如：logd.SetLevel(Lwarn)，系统只会打印大于等于Lwarn的日志。
+
+> 注意：logd.Printf() 和 logd.Print() 不论等级为什么都会输出，请悉知。
+
+#### Print Option
+系统提供多种格式输出选项：
+```
+Lasync                    // 异步输出日志
+Ldate                     // like 2006/01/02
+Ltime                     // like 15:04:05
+Lmicroseconds             // like 15:04:05.123123
+Llongfile                 // like /a/b/c/d.go:23
+Lshortfile                // like d.go:23
+LUTC                      // 时间utc输出
+Ldaily                    // 按天归档
+
+默认提供：
+ LstdFlags // 2006/01/02 15:04:05.123123, /a/b/c/d.go:23
+```
+
+#### 使用方法
+1、默认方式
+
+默认方式使用以下配置选项：
+```
+// 2006/01/02 15:04:05.123123, /a/b/c/d.go:23
+Lall      = Ldebug | Linfo | Lwarn | Lerror | Lfatal
+LstdFlags = Lall | Ldate | Lmicroseconds | Lshortfile
+```
+这里会打印所有等级日志，打印日志格式为`2006/01/02 15:04:05.123123, /a/b/c/d.go:23`
+
+可以通过`logd.SetLevel(level)`方式调整日志等级。`logd.SetOutput(writer)`输出日志到别的地方。例子：
+```
+package main
+
+import (
+	"fmt"
+	"os"
+
+	"github.com/deepzz0/logd"
+)
+
+func main() {
+	logd.Printf("Printf: foo\n")
+	logd.Print("Print: foo")
+
+	logd.Debugf("Debugf: foo\n")
+	logd.Debug("Debug: foo")
+
+	logd.Errorf("Errorf: foo\n")
+	logd.Error("Error: foo")
+
+	// 改变输出等级
+	logd.SetLevel(logd.Lerror)
+	// 不论等级如何都会输出
+	fmt.Println("----- 改变日志等级为Lerror -----")
+	logd.Printf("Printf: foo\n")
+	logd.Print("Print: foo")
+
+	logd.Debugf("Debugf: foo\n")
+	logd.Debug("Debug: foo")
+
+	logd.Errorf("Errorf: foo\n")
+	logd.Error("Error: foo")
+
+	fmt.Println("----- 日志等级为Lerror并写入到test.log中 -----")
+	f, err := os.Create("./test.log")
+	if err != nil {
+		panic(err)
+	}

+
+
+1、自定义配置
+推荐需要将日志保存下来的用户使用。
+
+```
+Flags := Lwarn | Lerror | Lfatal | Ldate | Ltime | Lshortfile | Ldaily | Lasync
+
+f, _ := os.OpenFile("testdata/onlyfile.log", os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0666)
+log := New(LogOption{
+	Out:        f,
+	Flag:       Flags,
+	LogDir:     "testdata",
+	ChannelLen: 1000,
+})
+```
+
+* 输出日志等级：Lwarn | Lerror | Lfatal
+* 输出日志格式：Ldate | Ltime | Lshortfile
+* 按日归档：Ldaily
+* 异步输出：Lasync
+
+它会将每天的日志，采用 gzip 压缩，并保留 30 天以内的日志。自动删除 30 以前的日志。
