C#微信接口之推送模板消息功能示例

本文实例讲述了c#微信接口之推送模板消息功能。分享给大家供大家参考，具体如下：

public string sendtempletmessge()
{
   string strreturn = string.empty;
   try
   {
     #region 获取access_token
     string apiurl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=你的appid&secret=你的secret";
     webrequest request = webrequest.create(@apiurl);
     request.method = "post";
     webresponse response = request.getresponse();
     stream stream = response.getresponsestream();
     encoding encode = encoding.utf8;
     streamreader reader = new streamreader(stream, encode);
     string detail = reader.readtoend();
     var jd = jsonconvert.deserializeobject<wxapi>(detail);
     string token = (string)jd.access_token;
     #endregion
     #region 组装信息推送，并返回结果（其它模版消息于此类似）
     string url = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=" + token;
     string temp = "{\"touser\": \"" + userinfo.openid + "\"," +
            "\"template_id\": \"f3krrjjeyldf4tndtg-ojervgedgjjdxcy4t9kuwm70\", " +
            "\"topcolor\": \"#ff0000\", " +
            "\"data\": " +
            "{\"first\": {\"value\": \"您好，您有一条回款通知信息\"}," +
            "\"keyword1\": { \"value\": \"单位名称\"}," +
            "\"keyword2\": { \"value\": \"日期\"}," +
            "\"keyword3\": { \"value\": \"金额\"}," +
            "\"keyword4\": { \"value\": \"业务员\"}," +
            "\"remark\": {\"value\": \"\" }}}";
     #endregion
   //核心代码
   getresponsedata(temp, @url);
     strreturn = "推送成功";
   }
   catch (exception ex)
   {
    strreturn = ex.message;
   }
   return strreturn;
}
/// <summary>
/// 返回json数据
/// </summary>
/// <param name="jsondata">要处理的json数据</param>
/// <param name="url">要提交的url</param>
/// <returns>返回的json处理字符串</returns>
public string getresponsedata(string jsondata, string url)
{
   byte[] bytes = encoding.utf8.getbytes(jsondata);
   httpwebrequest request = (httpwebrequest)webrequest.create(url);
   request.method = "post";
   request.contentlength = bytes.length;
   request.contenttype = "json";
   stream reqstream = request.getrequeststream();
   reqstream.write(bytes, 0, bytes.length);
   //声明一个httpwebrequest请求
   request.timeout = 90000;
   //设置连接超时时间
   request.headers.set("pragma", "no-cache");
   httpwebresponse response = (httpwebresponse)request.getresponse();
   stream streamreceive = response.getresponsestream();
   encoding encoding = encoding.utf8;
   streamreader streamreader = new streamreader(streamreceive, encoding);
   string strresult = streamreader.readtoend();
   streamreceive.dispose();
   streamreader.dispose();
   return strresult;
}

涉及到的实体：

public class wxapi
{
  public string access_token { set; get; }
}
