Teach you step by step how to connect PHP to the Enterprise WeChat interface

Enterprise WeChat is an instant messaging and office platform for enterprises developed by Tencent. For many enterprises, it is very important to interface with Enterprise WeChat. It can achieve seamless connection with the enterprise's internal system and provide convenience for information exchange and business processing.

This article will introduce how to use the PHP programming language to implement the interface with Enterprise WeChat. This will be explained in detail below using specific examples.

1. Configure Enterprise WeChat interface information

First, we need to configure the interface information in the Enterprise WeChat background. Log in to the enterprise WeChat backend management interface, click the "Applications and Mini Programs" menu, select the application to be connected, and enter the application details page. In the "Interfaces and Integration" column, click "Modify Configuration".

In the interface configuration, fill in the "URL" field, that is, Enterprise WeChat will send messages to the URL address. Fill in the "Token" field. Token is used to verify the legitimacy of the interface message. After filling in, save the configuration.

2. Set up a PHP development environment

Next, we need to set up a PHP development environment. You can use tools such as XAMPP or WAMP to build a local PHP environment.

3. Write PHP code

1. Create a PHP file that receives corporate WeChat messages, such as "wechat.php", and write the following code:

<?php
// 验证消息的合法性
$token = "your_token"; // 与企业微信配置中的Token保持一致
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$echostr = $_GET["echostr"];

$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr, SORT_STRING);
$tmpStr = implode($tmpArr);
$tmpStr = sha1($tmpStr);

if ($tmpStr == $signature) {
    echo $echostr;
    exit;
}

// 接收消息并处理
$postData = file_get_contents('php://input');
$xmlData = simplexml_load_string($postData, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUser = $xmlData->FromUserName;
$toUser = $xmlData->ToUserName;
$content = $xmlData->Content;

// 处理业务逻辑

// 回复消息
$reply = "收到消息：" . $content;
$response = "<xml>
<ToUserName><![CDATA[" . $fromUser . "]]></ToUserName>
<FromUserName><![CDATA[" . $toUser . "]]></FromUserName>
<CreateTime>" . time() . "</CreateTime>
<MsgType><![CDATA[text]]></MsgType>
<Content><![CDATA[" . $reply . "]]></Content>
</xml>";

echo $response;
?>

2. In the code, first verify the validity of the interface message. If the verification passes, return the "echostr" in the interface configuration. Next, by obtaining POST data, parsing the message in XML format, processing the business logic, and replying to the message.

4. Test interface docking

1. Place the written "wechat.php" file in the "htdocs" directory of the PHP development environment.
2. Start tools such as XAMPP or WAMP, open the browser, and enter the interface address, for example: http://localhost/wechat.php.
3. Log in to the enterprise WeChat backend, enter the application details page that needs to be connected, click the "Send Message" button, and send a message for testing.

Through the above steps, we can realize the connection between PHP and the enterprise WeChat interface. By writing corresponding business logic code, you can achieve richer functions, such as customizing menus, sending graphic messages, etc.

Summary

This article uses specific examples to teach you step by step how to connect PHP to the enterprise WeChat interface. By configuring the enterprise WeChat interface information, building a PHP development environment, and writing corresponding code, the function of receiving and replying to messages is realized. In this way, seamless connection with corporate WeChat can be achieved, making it convenient for enterprises to exchange information and handle business.

In actual applications, more functions can be implemented through the API interface provided by Enterprise WeChat, such as obtaining member information, sending template messages, etc. Through continuous learning and practice, we can make better use of the interfaces provided by Enterprise WeChat to optimize the company's business processes and improve work efficiency. I hope this article is helpful to everyone, welcome to read and refer to it.
