Sharing of Approval Application Development Tips for Connecting Enterprise WeChat Interface and PHP

Sharing of tips on docking the Enterprise WeChat interface and PHP approval application development

As a communication tool specially created for enterprises, Enterprise WeChat has powerful interface functions and can be connected with the enterprise's approval system to achieve Automate the approval process. This article will introduce the basic steps of enterprise WeChat interface docking, and share the skills of developing approval applications in combination with PHP.

1. Basic steps for enterprise WeChat interface docking

1. Register an enterprise WeChat account and create an application
   Enter the enterprise WeChat open platform (https://work.weixin.qq.com /), register a corporate account, and create your own application. Obtain the CorpID, Secret, and AgentID of the application. These parameters are needed for interface docking.
2. Get access_token
   Before sending an API request, you need to obtain the access_token to verify the calling authority of the interface. The access_token can be obtained through the interface provided by Enterprise WeChat. The specific implementation code is as follows:

$corpid = '企业的CorpID';
$corpsecret = '应用的Secret';
$url = 'https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=' . $corpid . '&corpsecret=' . $corpsecret;
$result = file_get_contents($url);
$json_result = json_decode($result, true);
$access_token = $json_result['access_token'];

3. Send a request
   Use the obtained access_token to send a request through the interface provided by Enterprise WeChat. function operation. For example, if you need to obtain a list of departments, you can use the following code:

$department_url = 'https://qyapi.weixin.qq.com/cgi-bin/department/list?access_token=' . $access_token;
$department_result = file_get_contents($department_url);
$department_list = json_decode($department_result, true);

4. Processing the returned results
   According to the results returned by the interface, perform corresponding processing. Usually, the return result of the enterprise WeChat interface is returned in JSON format, which can be converted into an array or object for processing using the json_decode function.

2. Approval application development skills

Based on the interface docking of Enterprise WeChat, rich approval applications can be developed to realize automated approval processes in various business scenarios. Here are some development tips to share.

1. Configure the approval process
   In the development process of the approval application, it is necessary to configure the approval process according to the actual needs of the enterprise. You can use the custom approval process interface provided by Enterprise WeChat to create, modify and query the approval process. For example, you can use the following code to create an approval process:

$create_process_url = 'https://qyapi.weixin.qq.com/cgi-bin/oa/applyevent?access_token=' . $access_token;
$data = array(
    // 审批流程的定义信息
);
$result = http_post_json($create_process_url, $data);

2. Initiating and processing approval applications
   A common need for developing approval applications is to enable employees to initiate approval applications in Enterprise WeChat, And be able to process application results in a timely manner. You can use the approval application interface provided by Enterprise WeChat to implement the function of initiating and processing approval applications. For example, the following is a code sample for initiating an approval application:

$apply_url = 'https://qyapi.weixin.qq.com/cgi-bin/oa/applyevent?access_token=' . $access_token;
$data = array(
    // 审批申请的具体信息
);
$result = http_post_json($apply_url, $data);

3. Receive and process approval notifications
   When there is a new approval notification, Enterprise WeChat will send a callback URL configured to the developer Send notification. Developers need to prepare an interface to receive and process approval notifications. For example, the following is a code example for receiving approval notification:

$json_data = file_get_contents("php://input");
$data = json_decode($json_data, true);
// 处理审批通知的逻辑

The above is a sharing of the approval application development skills for connecting the enterprise WeChat interface with PHP. I hope it will be helpful to developers in the development process of enterprise WeChat. Enterprise WeChat provides powerful interface functions. Combined with the flexibility of PHP, it can realize more complex approval processes and improve work efficiency and convenience. Developers can have an in-depth understanding of the interface documents of Enterprise WeChat based on actual needs, and flexibly apply the interface to create better tools for the enterprise's approval process.
