Enterprise WeChat interface docking and PHP check-in application development tutorial

Introduction:
Enterprise WeChat is an instant messaging tool specially provided for enterprises, and its interface can be used to develop some powerful enterprise applications , such as a clock-in application. This article will introduce how to use PHP language to connect with the enterprise WeChat interface and develop a simple but practical check-in application.

1. Create an enterprise WeChat application
   First, we need to create an application in the enterprise WeChat background. Log in to the enterprise WeChat backend, enter the [Applications and Mini Programs] - [Application Management] page, click the [Create Application] button, and fill in the application name, application logo and other information in the pop-up dialog box. After completing the creation, we can obtain the AgentID, CorpID and Secret of the application.
2. Get access_token
   When using the enterprise WeChat interface for docking, we need to obtain an access_token, which is valid for a certain period of time to facilitate subsequent interface calls. We can obtain the access_token through the following code:

$corpId = "你的CorpID";
$secret = "你的Secret";

$url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=".$corpId."&corpsecret=".$secret;
$result = file_get_contents($url);
$result = json_decode($result, true);

$accessToken = $result["access_token"];

3. Punch-in application development
   Let’s take a simple clock-in application as an example. The sample code is as follows:

$userId = "打卡用户的UserID";
$time = time();

$curl = curl_init();

$url = "https://qyapi.weixin.qq.com/cgi-bin/checkin/getcheckindata?access_token=".$accessToken;
$data = [
    "userid" => $userId,
    "opencheckindatatype" => 3,
    "starttime" => strtotime("-7 days"),  // 从7天前开始获取打卡记录
    "endtime" => $time,
];

curl_setopt_array($curl, [
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => json_encode($data),
    CURLOPT_HTTPHEADER => [
        'Content-Type: application/json',
        'Content-Length: ' . strlen(json_encode($data)),
    ],
]);

$response = curl_exec($curl);
curl_close($curl);

$result = json_decode($response, true);

if (isset($result["errmsg"]) && $result["errmsg"] == "ok") {
    $checkinData = $result["checkindata"];
    
    foreach ($checkinData as $data) {
        $date = date("Y-m-d", $data["checkin_time"]);
        $checkinType = $data["checkin_type"];
        
        echo "打卡日期：".$date." 打卡类型：".$checkinType."
";
    }
} else {
    echo "获取打卡记录失败";
}

In the above code, we obtain the check-in record of the specified user by calling the checkin interface of Enterprise WeChat. Among them, $userId is the UserID of the user to be queried, and $time is the current timestamp. After sending a request through the CURL library and getting the response, we can parse the returned JSON data, obtain the punch-in record, and display it.

Conclusion:
Through the introduction of this article, we learned how to use the enterprise WeChat interface for docking and developed a simple clock-in application. Of course, real enterprise WeChat application development is far more than this, and we can further expand application functions according to our own needs. This requires us to have a better understanding of the enterprise WeChat interface document and develop it based on actual project needs. Hope this article can help you!
