Sharing of voucher application skills for connecting the enterprise WeChat interface with PHP

With the rapid development of the mobile Internet, enterprises have an increasingly urgent need for instant communication and collaboration. As a communication tool specially created for enterprises, Enterprise WeChat has become the first choice of more and more enterprises. In order to meet the personalized needs of enterprises, WeChat Enterprise provides a wealth of application interfaces for developers to carry out customized development. This article will share relevant knowledge about Enterprise WeChat interface docking, and focus on how to use PHP language to apply for Enterprise WeChat credentials.

Basic concepts of enterprise WeChat interface docking

1. Certificate (Token): When an enterprise accesses the enterprise WeChat interface, it needs to provide a certificate for verification and decryption.
2. Application (Agent): The application provided by Enterprise WeChat can be understood as a functional module on Enterprise WeChat.
3. Authorized enterprise application: An application created by an enterprise on Enterprise WeChat and authorized by the enterprise.

Application and use of enterprise WeChat interface certificate
Before connecting to the enterprise WeChat interface, you first need to apply for a certificate. The following is an example of using PHP code to implement voucher application:

<?php
  $corpID = "企业ID";
  $corpSecret = "应用Secret";

  $getTokenUrl = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$corpID&corpsecret=$corpSecret";

  $response = file_get_contents($getTokenUrl);
  $result = json_decode($response, true);

  $accessToken = $result['access_token'];
?>

In the above code, the part that needs to be replaced:

1. Enterprise ID (corpID): obtained through the enterprise WeChat background, as The unique identifier of the enterprise.
2. Application Secret (corpSecret): When creating an application, Enterprise WeChat will generate an application Secret for obtaining credentials.

Through the above code, we can obtain a valid access certificate (accessToken), which is valid for 2 hours. In the subsequent development process, you can use this credential to access the interface of Enterprise WeChat.

Use the credentials to access the enterprise WeChat interface
After obtaining the credentials, we can use the credentials to access the enterprise WeChat interface. The following is an example of using PHP code to query the department list:

<?php
  $url = "https://qyapi.weixin.qq.com/cgi-bin/department/list?access_token=$accessToken";

  $response = file_get_contents($url);
  $result = json_decode($response, true);

  // 输出查询结果
  print_r($result);
?>

In the above code, what needs to be noted is the variable $accessToken, which is the valid voucher we obtained in the voucher application.

Through the above examples, we can see that the process of applying for credentials and accessing the enterprise WeChat interface is not complicated. It only takes a few simple steps to connect with Enterprise WeChat.
