How PHP implements interface communication with DingTalk

Introduction:
With the widespread application of DingTalk in work scenarios, many enterprises and developers need to communicate with DingTalk via PHP. This article will introduce how to use PHP to implement interface communication with DingTalk, and come with code examples.

1. Obtain the credentials and secret keys of the DingTalk open platform application
Before communicating with DingTalk through the interface, we first need to obtain the credentials and secret keys of the DingTalk open platform application. The specific steps are as follows:

1. Log in to DingTalk Open Platform (https://open-dev.dingtalk.com/);
2. Create a new application or add it to an existing application Obtain the credentials and secret key;
3. The obtained credentials and secret key will be used for subsequent interface calls.

2. Call the DingTalk interface through PHP
The following is a simple example code for calling the DingTalk interface through PHP:

<?php
// 钉钉开放平台应用的凭证和秘钥
$appkey = 'your_appkey';
$appsecret = 'your_appsecret';

// 基础接口URL
$base_url = 'https://oapi.dingtalk.com';

// 获取access_token
$access_token_url = $base_url . '/gettoken?appkey=' . $appkey . '&appsecret=' . $appsecret;
$access_token_json = file_get_contents($access_token_url);
$access_token_arr = json_decode($access_token_json, true);
$access_token = $access_token_arr['access_token'];

// 发送消息
$message_url = $base_url . '/robot/send?access_token=' . $access_token;
$data = [
    'msgtype' => 'text',
    'text' => [
        'content' => 'Hello, DingTalk!'
    ]
];
$data_string = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $message_url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

echo $response;
?>

In the above code, we first pass the credentials and the secret key to obtain the access_token for accessing the DingTalk interface, and pass it as a parameter to the interface that sends the message. What is sent in the sample code is a text message. You can also call other interfaces to perform more complex operations according to your needs.

3. Supplementary instructions

1. If you need to call an interface that requires authorization, such as obtaining a list of department members, etc., you can perform OAuth2.0 authorization operations according to the documentation of DingTalk Open Platform;
2. In actual development, for security reasons, you can save the credentials and secret keys in a safe place and read them through other methods; in addition, you can use PHP's encryption function to encrypt the credentials and secret keys. The key is encrypted.

Conclusion:
This article introduces how to use PHP to implement interface communication with DingTalk, and comes with a simple sample code. Through these methods, you can easily make interface calls with DingTalk in PHP to further expand the functions of DingTalk. I hope this article will be helpful to readers who need to interface with DingTalk.
