How to use the Enterprise WeChat interface and PHP message template

1. Introduction
Enterprise WeChat is an enterprise-level communication tool designed for internal communication and collaboration. It provides a powerful open interface that allows us to integrate with Enterprise WeChat through our own system to realize functions such as sending and receiving messages. This article will introduce how to use the enterprise WeChat interface, and combine it with PHP message templates to show the sample code of the interface call in detail.

2. Preparation

1. Register an enterprise WeChat account and create an enterprise, obtain the enterprise ID and application ID;
2. In the background management of enterprise WeChat, configure the application The callback URL is used to receive messages pushed by Enterprise WeChat.

3. Send messages
Enterprise WeChat provides multiple types of messages, including text, pictures, voice, video, documents, etc. The following takes sending a text message as an example to introduce in detail the steps and code examples for sending a message.

1. Get access_token
   Before sending the message, we need to obtain the access_token for authentication. The access_token is valid for 2 hours and needs to be obtained again after expiration.

Sample code:

$url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=your_corpid&corpsecret=your_corpsecret";
$response = file_get_contents($url);
$result = json_decode($response, true);
$access_token = $result['access_token'];

2. Constructing message content
   Constructing message content needs to be carried out according to the message template of Enterprise WeChat. The specific content includes touser (member of the recipient) ID list), msgtype (message type), agentid (ID of enterprise application), text (text message content), safe (whether to encrypt or not), etc.

Sample code:

$data = array(
    'touser' => 'user1|user2',
    'msgtype' => 'text',
    'agentid' => your_agentid,
    'text' => array(
        'content' => 'Hello World!'
    ),
    'safe' => 0
);

$json_data = json_encode($data, JSON_UNESCAPED_UNICODE);

3. Send message
   After constructing the message content, we can send the message by calling the interface of Enterprise WeChat.

Sample code:

$url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=" . $access_token;
$response = http_post($url, $json_data);
$result = json_decode($response, true);
$errcode = $result['errcode'];
if ($errcode == 0) {
    echo "消息发送成功！";
} else {
    echo "消息发送失败，错误码：".$errcode;
}

function http_post($url, $data)
{
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($curl);
    curl_close($curl);
    return $response;
}

4. Receive messages
In addition to sending messages, we can also receive messages through the enterprise WeChat interface. When receiving a message, Enterprise WeChat will send the message to our preset callback URL in the form of a POST request.

Sample code:

$postdata = file_get_contents("php://input");
$msg = json_decode($postdata, true);
$type = $msg['MsgType'];

switch ($type) {
    case 'text':
        $content = $msg['Content'];
        // 处理文本消息
        break;
    case 'image':
        $mediaId = $msg['MediaId'];
        // 处理图片消息
        break;
    // 其他类型消息的处理
    default:
        break;
}

The above is the basic method of using the enterprise WeChat interface and PHP message template. By calling the interface, we can realize message interaction with Enterprise WeChat, thereby improving the communication efficiency and collaboration within the enterprise. I hope this article will be helpful to you in actual development!
