WeChat development message push implementation skills (with code)

This article mainly introduces the message push implementation techniques for WeChat development (with code). For information about the message push implementation code, friends who need it can refer to it.

Recently I have been developing WeChat public accounts and there is a need. It is such a message push. The edited message is sent to an application group in the WeChat enterprise account in the form of text. Take notes here. The following is the organized content:

//定义数据模型
 
public class Access_token
{
public Access_token()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
string _access_token;
string _expires_in;
 
///
 
 
/// 获取到的凭证
///
 
public string access_token
{
get { return _access_token; }
set { _access_token = value; }
}
 
 
///
 
 
/// 凭证有效时间，单位：秒
///
 
public string expires_in
{
get { return _expires_in; }
 
 
set { _expires_in = value; }
}
 
}

 public ActionResult index(string returnUrl)
{
 
GetAccess_token()；
 
IsExistAccess_Token()；
 
return View();
}
 
 
 
public static Access_token GetAccess_token()
{
string AppUrl = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?";
string AppID = "应用组的CorpID";//在设置-》权限管理-》系统管理组
string AppSecret = "应用组的Secret";//在设置-》权限管理-》系统管理组
WebClient webClient = new WebClient();
Byte[] bytes = webClient.DownloadData(string.Format("{0}corpid={1}&corpsecret={2}", AppUrl, AppID, AppSecret));
string result = Encoding.GetEncoding("utf-8").GetString(bytes);
JObject jObj = JObject.Parse(result);
 
string token = jObj["access_token"].ToString();
string expires_in = jObj["expires_in"].ToString();
 
Access_token mode = new Access_token();
mode.access_token = token;
mode.expires_in = expires_in;
return mode;
}
 
///

Determine whether the Access_Token has expired based on the current date. If it expires, a new Access_Token will be returned. Otherwise, the previous Access_Token will be returned.
