DingTalk interface and PHP sign-in application development guide

DingTalk is a very popular enterprise-level communication tool. It provides a rich interface that allows developers to customize development according to their own needs. In this article, I will introduce to you how to use the DingTalk interface and PHP to develop a check-in application.

First, we need to create a custom robot on the DingTalk open platform. Open the DingTalk Open Platform website, register an account and log in. Enter the open platform console, click "Robot Management" in the left menu, and then click "Customize" to create a custom robot. After the creation is completed, a webhook address will be obtained, which will be used in subsequent development.

Next, we need to create a PHP project and introduce the dependency libraries required for development. We can use Composer to manage dependencies. In the composer.json file in the project root directory, add the following content:

{
    "require": {
        "guzzlehttp/guzzle": "^6.0"
    }
}

Then execute the composer install command and wait for the installation of dependent libraries to be completed.

Create a sign.php file in the project as the main logic file of the sign-in application.

Before you start writing code, you need to introduce dependent libraries and configuration items. I use the Guzzle library to send HTTP requests, so I need to introduce the Guzzle library files into the code.

<?php

require 'vendor/autoload.php';

use GuzzleHttpClient;

// 配置项
$webhook = '这里填入你的钉钉机器人webhook地址';
$secret = '这里填入你的钉钉机器人密钥';

Next, we need to write a sign-in function to handle the user's sign-in request.

function sign()
{
    global $webhook, $secret;
    
    // 获取当前时间戳
    $timestamp = time() * 1000;
    
    // 生成签名
    $sign = base64_encode(hash_hmac('sha256', $timestamp . "
" . $secret, $secret, true));
    
    // 构造请求数据
    $data = [
        'msgtype' => 'text',
        'text' => [
            'content' => '用户X已签到'
        ]
    ];
    
    // 发送请求
    $client = new Client();
    $client->request('POST', $webhook . '&timestamp=' . $timestamp . '&sign=' . urlencode($sign), [
        'json' => $data
    ]);
}

In this function, first get the current timestamp and generate a signature based on the timestamp and key. Then construct the request data and store the check-in content in the content field. Finally, use the Guzzle library to send a POST request to send the check-in information to the DingTalk robot.

Next step, we need to add a route to handle the user's check-in request.

// 路由处理
if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_POST['action']) && $_POST['action'] === 'sign') {
    sign();
    echo '签到成功';
    exit();
}

In this code, we determine whether the request method is POST, and determine whether there is an action parameter, and the value of this parameter is sign. If these conditions are met, the check-in function is called and a success message is returned.

Finally, we also need to add a button and corresponding form for sending a check-in request to the front-end page.

<!DOCTYPE html>
<html>
<head>
    <title>签到应用</title>
</head>
<body>
    <form method="post">
        <input type="hidden" name="action" value="sign">
        <button type="submit">签到</button>
    </form>
</body>
</html>

In this way, our sign-in application is developed.

Run the PHP project, visit this page, and click the sign-in button to complete the sign-in. After the sign-in is successful, DingTalk Robot will receive a notification message indicating that the user has signed in.

Through this example, we can see that it is quite simple to develop a check-in application by combining the DingTalk interface and PHP. Developers can conduct more complex customized development based on their own needs by combining other interfaces provided by DingTalk.
