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：
publicstringSendTempletMessge()
{
stringstrReturn=string.Empty;
try
{
#region获取access_token
stringapiurl="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=你的appid&secret=你的secret";
WebRequestrequest=WebRequest.Create(@apiurl);
request.Method="POST";
WebResponseresponse=request.GetResponse();
Streamstream=response.GetResponseStream();
Encodingencode=Encoding.UTF8;
StreamReaderreader=newStreamReader(stream,encode);
stringdetail=reader.ReadToEnd();
varjd=JsonConvert.DeserializeObject(detail);
stringtoken=(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）
stringurl="https://api.weixin.qq.com/cgi-bin/message/template/send?access_token="+token;
stringtemp="{\"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(Exceptionex)
{
strReturn=ex.Message;
}
returnstrReturn;
}
///
///返回JSon数据
///
///要处理的JSON数据
///要提交的URL
///返回的JSON处理字符串
publicstringGetResponseData(stringJSONData,stringUrl)
{
byte[]bytes=Encoding.UTF8.GetBytes(JSONData);
HttpWebRequestrequest=(HttpWebRequest)WebRequest.Create(Url);
request.Method="POST";
request.ContentLength=bytes.Length;
request.ContentType="json";
Streamreqstream=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");
HttpWebResponseresponse=(HttpWebResponse)request.GetResponse();
StreamstreamReceive=response.GetResponseStream();
Encodingencoding=Encoding.UTF8;
StreamReaderstreamReader=newStreamReader(streamReceive,encoding);
stringstrResult=streamReader.ReadToEnd();
streamReceive.Dispose();
streamReader.Dispose();
returnstrResult;
}
