微信平台接入Web页面功能接口（C#）

微信平台接入web页面功能接口

今年因工作需要，通过微信平台接入公司的Wap页面，回忆下，记录内容，方面以后使用。

1.成为开发者后，你才可以使用公众平台的开发功能。需要填写URL和ToKen,接口配置信息。

2.服务器端开发如下接口，等待微信服务器调用。

URL：

用来接收微信服务器数据的接口URL，

http://192.168.0.199/weixin/****.ashx（该地址不固定，可以由后台开发者根据实际情况自己拟定，但只支持80端口）

Token：

开发者可以任意拟定，已备用作生成签名（该Token会和接口URL中包含的Token进行比对，从而验证安全性）。

请求方式：

Get

接收参数：

参数	描述
signature	微信加密签名，signature结合了开发者填写的token参数和请求中的timestamp参数、nonce参数。
timestamp	时间戳
nonce	随机数
echostr	随机字符串

响应微信服务器：

开发者通过检验signature对请求进行校验（下面有校验方式）。若确认此次GET请求来自微信服务器，请原样返回echostr参数内容，则接入生效，否则接入失败。

加密/校验流程如下：

1. 将token、timestamp、nonce三个参数进行字典序排序

2. 将三个参数字符串拼接成一个字符串进行sha1加密

3. 开发者获得加密后的字符串可与signature对比，标识该请求来源于微信

3. 在公众平台网站的高级功能 – 开发模式页，点击“成为开发者”按钮，填写URL和Token。提交信息后，微信服务器将发送GET请求到填写的URL上，进行接入验证。

4.C#代码

object signature = context.Request.QueryString["signature"];
    object timestamp = context.Request.QueryString["timestamp"];
    object nonce = context.Request.QueryString["nonce"];
    object echoStr = context.Request.QueryString["echoStr"];
    if (signature != null && signature.ToString() != "" && timestamp != null && timestamp.ToString() != "" && nonce != null && nonce.ToString() != "" && echoStr != null && echoStr.ToString() != "")
            {
                CheckSignature(signature.ToString(), timestamp.ToString(), nonce.ToString(), echoStr.ToString(), token);
            }

        /// <summary>
        /// 验证微信 字典排序后 返回随机数
        /// </summary>
        /// 将token、timestamp、nonce三个参数进行字典排序
        /// 将三个参数字符串拼接成一个字符串sha1加密
        /// 获取加密后的字符串可与signature 对比 如果为true则返回随数
        /// <returns></returns>
        private void CheckSignature(string signature, string timestamp, string nonce, string echoStr, string Token)
        {

            string[] ArrTmp = { Token, timestamp, nonce };
            Array.Sort(ArrTmp);     //首º¡Á先¨¨字Á?典Ì?排?序¨°
            string tmpStr = string.Join("", ArrTmp);
            tmpStr = FormsAuthentication.HashPasswordForStoringInConfigFile(tmpStr, "SHA1");  //sha1
            tmpStr = tmpStr.ToLower();
            if (tmpStr == signature)
            {
                if (!string.IsNullOrEmpty(echoStr))
                {
                    System.Web.HttpContext.Current.Response.Write(echoStr);
                    System.Web.HttpContext.Current.Response.End();
                }
            }
        }

5.验证通过后，就可以得到appid 和secret参数了

6.创建菜单

（1）目前自定义菜单最多包括3个一级菜单，每个一级菜单最多包含5个二级菜单。一级菜单最多4个汉字，二级菜单最多7个汉字，多出来的部分将会以“...”代替。请注意，创建自定义菜单后，由于微信客户端缓存，需要24小时微信客户端才会展现出来。建议测试时可以尝试取消关注公众账号后再次关注，则可以看到创建后的效果。

目前自定义菜单接口可实现两种类型按钮，如下：

click：

用户点击click类型按钮后，微信服务器会通过消息接口推送消息类型为event       的结构给开发者（参考消息接口指南），并且带上按钮中开发者填写的key值，开发者可以通过自定义的key值与用户进行交互；

view：

用户点击view类型按钮后，微信客户端将会打开开发者在按钮中填写的url值        （即网页链接），达到打开网页的目的，建议与网页授权获取用户基本信息接口结合，获得用户的登入个人信息。

（2）示例：

接口调用请求说明

http请求方式：POST（请使用https协议）

https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN

请求示例

{

     "button":[

     {   

          "type":"click",

          "name":"今日歌曲",

          "key":"V1001_TODAY_MUSIC"

      },

      {

           "type":"click",

           "name":"歌手简介",

           "key":"V1001_TODAY_SINGER"

      },

      {

           "name":"菜单",

           "sub_button":[

           {     

               "type":"view",

               "name":"搜索",

               "url":"http://www.soso.com/"

            },

            {

               "type":"view",

               "name":"视频",

               "url":"http://v.qq.com/"

            },

            {

               "type":"click",

               "name":"赞一下我们",

               "key":"V1001_GOOD"

            }]

       }]

 }

参数说明

参数	是否必须	说明
button	是	一级菜单数组，个数应为1~3个
sub_button	否	二级菜单数组，个数应为1~5个
type	是	菜单的响应动作类型，目前有click、view两种类型
name	是	菜单标题，不超过16个字节，子菜单不超过40个字节
key	click类型必须	菜单KEY值，用于消息接口推送，不超过128字节
url	view类型必须	网页链接，用户点击菜单可打开链接，不超过256字节

返回结果

正确时的返回JSON数据包如下：

{"errcode":0,"errmsg":"ok"}

错误时的返回JSON数据包如下（示例为无效菜单名长度）：

{"errcode":40018,"errmsg":"invalid
button name size"}

7.接口逻辑操作 统一接口

（1）菜单也可以为：

"\"type\":\"click\"," +

"\"name\":\"快乐每一天\"," +

"\"key\":\"yc_jbcg\""+

以xml文本形式传递参数
