[转载]维权接口

1.你需确定维权URL通知地址；

在“商户功能→商户信息→修改→维权通知URL”查看维权通知URL。（区分大小写）

2.添加用户维权入口

在服务号自定义菜单添加名称叫“维权”的菜单，该菜单不分层级，不分位置，微信自动跳转到维权页面。。

3.获取维权通知XML数据。

在ResponseHandler类（微信支付----没我想的那么难:http://www.2cto.com/weixin/201408/323334.html ）添加获取XML参数的方法：

/**获取XML参数**/
       public string getMpParameter(string parameter) {
           string s = (string)xmlMap[parameter];
           return (null == s) ? "" : s;
       }

在URL通知页面获取数据：

if (!IsPostBack) {
           //创建支付应答对象
           ResponseHandler resHandler = new ResponseHandler(Context);
           resHandler.init();
           resHandler.setKey(TenpayUtil.key, TenpayUtil.appkey);
           //判断签名
           if (resHandler.isWXsignfeedback()) {
               string AppId = resHandler.getMpParameter("AppId");
               string TimeStamp = resHandler.getMpParameter("TimeStamp");
               string OpenId = resHandler.getMpParameter("OpenId");
               string AppSignature = resHandler.getMpParameter("AppSignature");
               string MsgType = resHandler.getMpParameter("MsgType");
               string FeedBackId = resHandler.getMpParameter("FeedBackId");
               string TransId = resHandler.getMpParameter("TransId");
               string Reason = resHandler.getMpParameter("Reason");
               string Solution = resHandler.getMpParameter("Solution");
               string ExtInfo = resHandler.getMpParameter("ExtInfo");
               string SignMethod = resHandler.getParameter("SignMethod");
               string txt = string.Empty;
               if (MsgType.ToLower().Trim() == "request") {
                 //新增维权操作
               }
               else {
                 //用户确认处理完毕操作
               }
 
               //回复服务器处理成功
               Response.Write("OK");
               Response.Write("OK:" + resHandler.getDebugInfo());
           }
           else {
               //sha1签名失败
               Response.Write("fail");
               Response.Write("fail:" + resHandler.getDebugInfo());
           }
           Response.End();
       }

4.申请消除投诉

如您已经跟客户达成一致，可申请消除用户投诉！

/// <summary>
    /// 向微信发送撤销投诉申请
    /// </summary>
    /// <returns></returns>
    private void MessageToTx(string accessToken, string openId, string feedBackId) {
        string url = "https://api.weixin.qq.com/payfeedback/update?access_token={0}&openid={1}&feedbackid={2}";
        url = string.Format(url, accessToken, openId, feedBackId);
        HttpWebRequest webRequest2 = (HttpWebRequest)WebRequest.Create(url);
        webRequest2.ContentType = "text/html; charset=UTF-8";
        webRequest2.Method = "GET";
        webRequest2.UserAgent = "Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1";
        HttpWebResponse httpWebResponse2 = (HttpWebResponse)webRequest2.GetResponse();
        StreamReader swRead = new StreamReader(httpWebResponse2.GetResponseStream(), System.Text.Encoding.GetEncoding("UTF-8"));
        Write(swRead.ReadToEnd());
    }
