This article uses Java to develop the WeChat public account case code, how to access the public account, how about the subscription accountReceive messages, has certain reference value, interested friends can refer to it

WeChat public account development is generally aimed at enterprises and organizations. Individuals can generally only apply for a subscription account, and the interface called is limited. Let’s briefly describe the access. Steps for public account :

1. First, you need an email address to register on the WeChat public account platform;
Registration methods include subscription account, public account, mini program and enterprise account , personally we can only choose the subscription account

2. After registration, we log in to the official account platform --->Development--->Basic configuration, here we need to fill in the URL and token , the URL is the interface we use the server;

3. If the Java Web server program is compiled and deployed on the server and can run, the online interface can be performed on the WeChat official accountDebugging ：

1). Select the appropriate interface
2) The system will generate the parameter table of the interface. You can directly fill in the corresponding parameter value in the text box (red asterisk indicates This field is required)
3) Click the Check Problem button to get the corresponding debugging information

eg: Steps to obtain access_token:

1), Interface type: basic support
2), Interface list: Get access_token interface/token
3), fill in the corresponding parameters: grant_type, appid, secret
4), click to check Question
5) If the verification is successful, the result and prompt will be returned. The result is: 200 ok. The prompt: Request successful means the verification is successful.

What we verify more here is the message interface debugging: text Messages, picturesmessages, voice messages, videomessages, etc

4. If you don’t understand the interface, you can enter development-->Development Developer tools-->Developer documentation for query

5. Interface permissions: Subscription accounts mainly have basic support, receiving messages and some interfaces in web services

Below we will mainly talk about the case of how subscription accounts receive messages:

1. You need to apply for a personal WeChat subscription account
2. URL server And server-side code deployment (you can use Tencent Cloud or Alibaba Cloud server)

1), AccountsServlet.java class, verification comes from WeChat Message processing of the server and WeChat server

package cn.jon.wechat.servlet;

 public void doGet(HttpServletRequest request, HttpServletResponse response) 
  throws ServletException, IOException {

  //微信加密簽名

  PrintWriter out = response.getWriter(); 
  //通過(guò)校驗(yàn)signature對(duì)請(qǐng)求進(jìn)行校驗(yàn)，若校驗(yàn)成功則原樣返回echostr，表示接入成功，否則接入失敗 
  if(SignUtil.checkSignature(signature,timestamp,nonce)){ 
  out.print(echostr); 
  } 
  out.close(); 
  out = null; 
//  response.encodeRedirectURL("success.jsp"); 
  
  
 } 
 /**

 public void doPost(HttpServletRequest request, HttpServletResponse response) 
  throws ServletException, IOException {

 } 
 
 public void init() throws ServletException { 
 // Put your code here

}

2), SignUtil.java class, request verification tool class, the token needs to be consistent with the token filled in WeChat

package cn.jon.wechat.utils;

 return stnStr!=null?stnStr.equals(signature.toUpperCase()):false; 
 }

 } 
}

3), AccountsService.java service class, mainly for message request and response processing, and when the user follows your official account, you can set the default Push message
