PHP realizes enterprise WeChat interface docking skills and performance optimization

Small and medium-sized enterprises are increasingly using Enterprise WeChat for internal communication and collaboration. Interfacing with Enterprise WeChat is one of the inevitable tasks for developers. This article will introduce the skills of PHP to implement enterprise WeChat interface docking, and provide some suggestions for performance optimization.

1. Obtain access_token

When connecting with Enterprise WeChat, you first need to obtain access_token. access_token is a globally unique ticket called by the enterprise WeChat interface and is valid for 2 hours. We can obtain the access_token through the following code:

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

    if (isset($result['access_token'])) {
        return $result['access_token'];   
    } else {
        // 处理获取失败的情况
    }
}

2. Send a message

Enterprise WeChat provides a variety of message types, including text, pictures, links, cards, videos, etc. The following is an example of sending a text message:

function sendTextMessage($access_token, $touser, $content) {
    $url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={$access_token}";
    $data = array(
        'touser' => $touser,
        'msgtype' => 'text',
        'text' => array(
            'content' => $content
        )
    );

    $options = array(
        'http' => array(
            'method' => 'POST',
            'header' => "Content-type: application/json",
            'content' => json_encode($data)
        )
    );

    $context = stream_context_create($options);
    $response = file_get_contents($url, false, $context);
    $result = json_decode($response, true);

    if ($result['errcode'] == 0) {
        // 消息发送成功
    } else {
        // 处理消息发送失败的情况
    }
}

3. Performance Optimization

1. Caching access_token

Getting access_token is a frequent operation. In order to avoid Frequently calling the interface to obtain access_token, we can cache the access_token, use caching tools such as Redis or Memcached to store the access_token, and set an appropriate expiration time.

2. Using concurrent requests

The efficiency of interface calls can be improved by using multi-threads or multi-processes for concurrent requests. You can use PHP's cURL extension to implement concurrent requests. The following is a sample code that uses cURL extension to implement concurrent requests:

function sendConcurrentRequest($urls) {
    $mh = curl_multi_init();
    $handles = array();

    foreach ($urls as $key => $url) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_multi_add_handle($mh, $ch);

        $handles[$key] = $ch;
    }

    $running = null;
    do {
        curl_multi_exec($mh, $running);
    } while ($running > 0);

    $results = array();
    foreach ($handles as $key => $ch) {
        $results[$key] = curl_multi_getcontent($ch);
        curl_multi_remove_handle($mh, $ch);
    }

    curl_multi_close($mh);

    return $results;
}

The above is a brief introduction to the skills and performance optimization of PHP's implementation of enterprise WeChat interface docking. In practical applications, more detailed implementation and adjustments need to be made according to specific needs. I hope this article can provide you with some help in implementing enterprise WeChat interface docking in PHP.
