Enterprise WeChat interface docking and PHP approval application development tutorial

Enterprise WeChat is an enterprise communication tool launched by Tencent, which provides powerful enterprise-level functions, such as organizational structure management, enterprise application management, messaging Synchronize with address book and more. Enterprise WeChat opens a wealth of interfaces for developers to connect and develop applications, providing more personalized and customized enterprise-level applications.

This article will focus on the docking of the enterprise WeChat interface and the development of PHP approval applications. The following are detailed steps and code examples:

Step one: Create an enterprise WeChat application and obtain interface credentials

In the enterprise WeChat developer platform (https://open.work.weixin. Create a new enterprise WeChat application in qq.com/). During the creation process, you can select "Approval Application" as the application type and obtain a unique AgentId and Secret.

Step 2: Obtain access_token

Obtain access_token by sending a GET request to the enterprise WeChat interface. The specific code examples are as follows:

$corpid = '企业ID';
$corpsecret = '应用Secret';

$url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={$corpid}&corpsecret={$corpsecret}";

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

$access_token = $data['access_token'];

Step 3: Receive approval events

The enterprise WeChat approval application needs to monitor the approval events, which can be achieved by calling the callback URL provided by Enterprise WeChat. Specific code examples are as follows:

$callback_data = file_get_contents('php://input');
$data = json_decode($callback_data , true);

$eventType = $data['EventType'];
$approvalEvent = $data['Event']['Approval'];

if ($eventType == 'open_approval_change') {
    // 处理审批事件
}

Step 4: Processing approval events

The processing logic of approval events will be written according to actual needs, which can realize the creation of approval applications, update of approval results, etc. Function. The following is a simple sample code:

function createApproval($approvalData, $access_token) {
    $url = "https://qyapi.weixin.qq.com/cgi-bin/oa/applyevent?access_token={$access_token}";

    $data = [
        'creator_userid' => '创建人用户ID',
        'template_id' => '审批模板ID',
        'approver' => [
            'userid' => ['审批人用户ID']
        ],
        'notifyer' => [
            'userid' => ['抄送人用户ID']
        ],
        'notify_type' => '0',
        'apply_data' => $approvalData
    ];

    $options = [
        'http' => [
            'header' => "Content-type: application/json
",
            'method' => 'POST',
            'content' => json_encode($data)
        ]
    ];

    $context = stream_context_create($options);
    $response = file_get_contents($url, false, $context);

    $result = json_decode($response, true);

    if ($result['errcode'] == 0) {
        // 审批创建成功
    } else {
        // 审批创建失败
    }
}

The above code sample demonstrates how to create an approval application and send the request to the enterprise WeChat interface. Specific parameters and data structures can be adjusted and expanded according to the official WeChat Enterprise documents.

Through the above steps, we can complete the docking of the enterprise WeChat interface and the development of PHP approval applications. Enterprise WeChat provides a wealth of interfaces and functions, and can carry out customized application development according to the needs of the enterprise, improving the communication efficiency and work efficiency of the enterprise. I hope this article will be helpful for you to understand and apply the enterprise WeChat interface and PHP development.
