 ```

-#### 和主流框架配合使用
-
-主要是request和responseWriter在不同框架中获取方式可能不一样：
-
- Beego: [./examples/beego/beego.go](./examples/beego/beego.go)
- Gin Framework: [./examples/gin/gin.go](./examples/gin/gin.go)

->关注公众号并回复“入群”
-
-## 基本配置
-
-```go
-memcache := cache.NewMemcache("127.0.0.1:11211")
-
-wcConfig := &wechat.Config{
-	AppID:          cfg.AppID,
-	AppSecret:      cfg.AppSecret,
-	Token:          cfg.Token,
-	EncodingAESKey: cfg.EncodingAESKey,//消息加解密时用到
-	Cache:          memcache,
-}
-```
-
-**Cache 设置**
-
-Cache主要用来保存全局access_token以及js-sdk中的ticket：
-默认采用memcache存储。当然也可以直接实现`cache/cache.go`中的接口

-
-	}
-
-
-```
-
-
-### 被动回复消息
-
-回复消息需要返回 `*message.Reply` 对象结构体如下：
-
-```go
-type Reply struct {
-	MsgType MsgType  //消息类型
-	MsgData interface{}  //消息结构
-}
-
-```
-注意：`return nil`表示什么也不做
-

-```go
-	text := message.NewText("回复文本消息")
-	return &message.Reply{message.MsgTypeText, text}
-```
-####  回复图片消息

-
-```go
-articles := make([]*message.Article, 1)
-
-article := new(message.Article)
-article.Title = "标题"
-article.Description = "描述信息信息信息"
-article.PicURL = "http://ww1.sinaimg.cn/large/65209136gw1f7vhjw95eqj20wt0zk40z.jpg"
-article.URL = "https://github.com/silenceper/wechat"
-articles[0] = article
-
-news := message.NewNews(articles)
-return &message.Reply{message.MsgTypeNews,news}
-```
-**字段说明：**
-
-Title：图文消息标题
-
-Description：图文消息描述
-
-PicUrl	：图片链接，支持JPG、PNG格式，较好的效果为大图360*200，小图200*200

-
-## 自定义菜单
-
-通过` wechat.GetMenu()`获取menu的实例
-
-### 自定义菜单创建接口
-
-以下是一个创建二级菜单的例子

-
-buttons := make([]*menu.Button, 1)
-btn := new(menu.Button)
-
-//创建click类型菜单
-btn.SetClickButton("name", "key123")
-buttons[0] = btn
-
-//设置btn为二级菜单
-btn2 := new(menu.Button)
-btn2.SetSubButton("subButton", buttons)
-
-buttons2 := make([]*menu.Button, 1)
-buttons2[0] = btn2
-
-//发送请求
-err := mu.SetMenu(buttons2)
-if err != nil {
-	fmt.Printf("err= %v", err)
-	return
-}
-
-```
-
-**创建其他类型的菜单：**
-
-```go
-//SetViewButton view类型
-func (btn *Button) SetViewButton(name, url string)
-
-// SetScanCodePushButton 扫码推事件
-func (btn *Button) SetScanCodePushButton(name, key string)
-
-//SetScanCodeWaitMsgButton 设置 扫码推事件且弹出"消息接收中"提示框
-func (btn *Button) SetScanCodeWaitMsgButton(name, key string)
-
-//SetPicSysPhotoButton 设置弹出系统拍照发图按钮
-func (btn *Button) SetPicSysPhotoButton(name, key string)
-
-//SetPicPhotoOrAlbumButton 设置弹出拍照或者相册发图类型按钮
-func (btn *Button) SetPicPhotoOrAlbumButton(name, key string) {
-
-// SetPicWeixinButton 设置弹出微信相册发图器类型按钮
-func (btn *Button) SetPicWeixinButton(name, key string)
-
-// SetLocationSelectButton 设置 弹出地理位置选择器 类型按钮
-func (btn *Button) SetLocationSelectButton(name, key string)
-
-//SetMediaIDButton  设置 下发消息(除文本消息) 类型按钮
-func (btn *Button) SetMediaIDButton(name, mediaID string)
-
-//SetViewLimitedButton  设置 跳转图文消息URL 类型按钮
-func (btn *Button) SetViewLimitedButton(name, mediaID string) {
-
-```
-
-### 自定义菜单查询接口
-
-```go
-mu := wc.GetMenu()
-resMenu,err:=mu.GetMenu()
-```
->返回结果 resMenu 结构参考 ./menu/menu.go 中ResMenu 结构体
-
-### 自定义菜单删除接口
-
-```go
-mu := wc.GetMenu()
-err:=mu.DeleteMenu()
-```
-
-### 自定义菜单事件推送
-
- 请参考 消息管理 - 事件推送
-
-### 个性化菜单接口
-**添加个性化菜单**
-
-```go
-
-func (menu *Menu) AddConditional(buttons []*Button, matchRule *MatchRule) error
-```
-
-**删除个性化菜单**
-
-```go
-//删除个性化菜单
-func (menu *Menu) DeleteConditional(menuID int64) error
-
-```
-**测试个性化菜单匹配结果**
-
-```go
-//菜单匹配
-func (menu *Menu) MenuTryMatch(userID string) (buttons []Button, err error) {
-
-```
-
-### 获取公众号菜单配置
-
-```go
-//获取自定义菜单配置接口
-func (menu *Menu) GetCurrentSelfMenuInfo() (resSelfMenuInfo ResSelfMenuInfo, err error)
-
-```
-
-## 微信网页开发
-
-### Oauth2 授权
-
-具体授权流程请参考微信文档：[网页授权](http://mp.weixin.qq.com/wiki/4/9ac2e7b1f1d22e9e57260f6553822520.html)
-
-**1.发起授权**
-
-```go
-oauth := wc.GetOauth()
-err := oauth.Redirect("跳转的绝对地址", "snsapi_userinfo", "123dd123")
-if err != nil {
-	fmt.Println(err)
-}
-
-```
-> 如果不希望直接跳转，可通过 oauth.GetRedirectURL 获取跳转的url
-
-**2.通过code换取access_token**
-
-```go
-code := c.Query("code")
-resToken, err := oauth.GetUserAccessToken(code)
-if err != nil {
-	fmt.Println(err)
-	return
-}
-
-```
-**3.拉取用户信息(需scope为 snsapi_userinfo)**
-
-```go
-//getUserInfo
-userInfo, err := oauth.GetUserInfo(resToken.AccessToken, resToken.OpenID)
-if err != nil {
-	fmt.Println(err)
-	return
-}
-fmt.Println(userInfo)
-
-```
-**刷新access_token**
-
-```go
-func (oauth *Oauth) RefreshAccessToken(refreshToken string) (result ResAccessToken, err error)
-
-```
-**检验access_token是否有效**
-
-```go
-func (oauth *Oauth) CheckAccessToken(accessToken, openID string) (b bool, err error)
-```
-
-### 获取js-sdk配置
-
-```go
-js := wc.GetJs()
-cfg, err := js.GetConfig("传入需要的调用js-sdk的url地址")
-if err != nil {
-	fmt.Println(err)
-	return
-}
-fmt.Println(cfg)
-```
-其中返回的cfg结构体如下：
-
-```go
-type Config struct {
-	AppID     string `json:"app_id"`
-	Timestamp int64  `json:"timestamp"`
-	NonceStr  string `json:"nonce_str"`
