Practical steps for implementing image and text message push through Enterprise WeChat interface and PHP

1. Introduction
Enterprise WeChat is an enterprise-level application platform that integrates instant messaging, enterprise management, application development and other functions. Within the enterprise, enterprise WeChat can be used to communicate, collaborate and manage quickly and conveniently. Among them, graphic messages are a commonly used form of push content, which can attract users' attention and provide rich information display. This article will introduce how to push corporate WeChat graphic messages through PHP, and provide specific practical steps and code examples.

2. Preparation work
Before starting the implementation, the following preparation work needs to be done:

1. Apply for enterprise WeChat application: first create or obtain an enterprise WeChat application, and obtain the corresponding CorpID and Secret.
2. Install the PHP environment: Make sure the PHP environment has been installed on the machine and the cURL extension is enabled.

3. Obtain Access Token
Access Token is the identity credential when accessing the interface through the Enterprise WeChat API and needs to be obtained and updated again. Access Token can be obtained through the following code:

<?php
$corpid = "企业的CorpID";
$corpsecret = "企业应用的Secret";

$url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$corpid&corpsecret=$corpsecret";
$result = json_decode(file_get_contents($url));
$access_token = $result->access_token;
?>

Replace "CorpID of the enterprise" and "Secret of the enterprise application" in the above code with the actual CorpID and Secret.

4. Construct graphic messages
Before constructing graphic messages, you need to understand the format requirements of corporate WeChat graphic messages:

$msg = array(
    "touser" => "UserID1|UserID2", //指定用户，多个用户使用竖线分隔
    "agentid" => 1000002, //企业应用的agentid
    "msgtype" => "news", //消息类型，固定为news
    "news" => array(
        "articles" => array(
            array(
                "title" => "标题",
                "description" => "描述",
                "url" => "跳转链接",
                "picurl" => "图片链接"
            ),
            //可以添加更多的文章
        )
    )
);

Construct corresponding graphic message content according to needs .

5. Push graphic messages
Using the constructed graphic message and Access Token, you can push graphic messages through the Enterprise WeChat API. The following is a code example for pushing a graphic message:

<?php
$url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=$access_token";
$data = json_encode($msg);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt( $ch,CURLOPT_SSL_VERIFYHOST,false);
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER,false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);

$response = json_decode($result);
if ($response->errcode == 0) {
    echo "推送成功";
} else {
    echo "推送失败：" . $response->errmsg;
}
?>

Replace $msg in the above code with the constructed graphic message.

6. Summary
Through the above steps, we can push corporate WeChat graphic messages through PHP. First obtain the Access Token, then construct the content of the graphic message, and finally use the Enterprise WeChat API to push the message. This makes it easy to push graphic messages to designated users in Enterprise WeChat, providing relevant information and content display.

I hope this article will be helpful to everyone in understanding the enterprise WeChat interface and how to implement image and text message push with PHP, and trigger more interest in learning and practice. In practice, you need to pay attention to protecting the enterprise's CorpID and Secret, and ensuring the validity of the Access Token used in the code. At the same time, you can further explore the applications of other enterprise WeChat interfaces to expand more functions and implement requirements. I wish you all success in your enterprise WeChat development practice!
