Analysis of the implementation of the message withdrawal function of DingTalk interface and PHP

In the internal communication and collaboration of DingTalk enterprises, the message withdrawal function is a very important function. Users can use this function to recall messages when sending an incorrect message or recalling an inappropriate message. This article will introduce how to use the PHP programming language combined with the DingTalk interface to implement the message withdrawal function, and give corresponding code examples.

DingTalk provides a series of interfaces to meet the needs of internal corporate communication, including interfaces for withdrawing messages. Before using this interface, we first need to obtain the necessary parameters for calling the interface, such as access_token and message_id. access_token is the identity credential when accessing the DingTalk open platform interface, and is used to identify the caller's identity and permissions. message_id is the unique identifier of the message that needs to be recalled.

Next, we use PHP to write code to implement the message withdrawal function. First, we need to save the following code as a separate PHP file and upload it to the server:

<?php

// 定义钉钉接口地址
$url = 'https://oapi.dingtalk.com/robot/send?access_token=ACCESS_TOKEN';

// 定义待撤回的消息的message_id
$message_id = 'MESSAGE_ID';

// 定义发送的数据
$data = array(
    'msgtype' => 'actionCard',
    'actionCard' => array(
        'title' => '消息撤回',
        'text' => '',
        'hideAvatar' => '0',
        'btnOrientation' => '0',
        'singleTitle' => '撤回消息',
        'singleURL' => ''
    )
);

// 将数据转换为JSON格式
$json_data = json_encode($data);

// 发送HTTP请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// 解析返回数据
$result = json_decode($response, true);
if ($result['errcode'] == 0) {
    echo '消息撤回成功！';
} else {
    echo '消息撤回失败：' . $result['errmsg'];
}

?>

In the above code, we first define the address of the DingTalk interface and the message_id of the message to be withdrawn . We then define the message data to be sent, which includes the type of message, title, and content about the undo button. Next, we convert the data into JSON format and send the data to the DingTalk interface through an HTTP request. Finally, we parse the returned data, and if the withdrawal of the message is successful, a prompt message is output; if the withdrawal of the message fails, an error message is output.

It should be noted that ACCESS_TOKEN in the above code should be replaced with the real access_token, and MESSAGE_ID should be replaced with the real message_id. Before using the DingTalk interface, we need to obtain the legal access_token and the message_id of the message to be withdrawn.

When using the above code to implement the message withdrawal function, you can deploy it on the server and call the interface by accessing the URL of the PHP file. After successfully withdrawing the message, you will get the corresponding prompt information.

To summarize, this article introduces how to use the PHP programming language combined with the DingTalk interface to implement the message withdrawal function, and provides corresponding code examples. I hope this article can provide some help and reference to readers in need.
