EasyWeChat and PHP tips for implementing sharing functions in WeChat mini programs

With the popularity of WeChat mini programs, developers are paying more and more attention to how to implement sharing functions in WeChat mini programs. In this article, we will introduce how to use EasyWeChat and PHP to develop the sharing function of WeChat applet and provide code examples.

1. Preparatory work

Before we start, we need to prepare some basic development environment and materials:

1. WeChat public platform account: Register a WeChat public Platform account and create a mini program.
2. EasyWeChat: Install the EasyWeChat library, which provides many convenient functions to interact with the WeChat interface.
3. PHP environment: Set up a PHP environment and install the Composer package management tool.

2. EasyWeChat configuration

First, we need to introduce EasyWeChat into the project. EasyWeChat can be easily installed using Composer. Just run the following command in the project root directory:

composer require overtrue/wechat

After the installation is complete, introduce EasyWeChat's automatic loading file into the project:

require_once 'vendor/autoload.php';

Next , we need to configure EasyWeChat. Create a config.php file in the project root directory and configure it according to the following code:

<?php
return [
    'app_id' => 'YOUR_APP_ID',
    'secret' => 'YOUR_APP_SECRET',
    'token' => 'YOUR_TOKEN',
    'log' => [
        'level' => 'debug',
        'file' => 'path/to/log.log',
    ],
];

Replace YOUR_APP_ID, YOUR_APP_SECRET and YOUR_TOKEN with the AppID, AppSecret and Token of your applet. The log configuration is optional and is used for logging.

3. Implement the sharing function

After completing the configuration of EasyWeChat, we start to implement the sharing function.

1. Get access_token

The sharing function requires access_token. We can use the API provided by EasyWeChat to obtain access_token. Add the following code to the config.php file:

$wechat = new EasyWeChatFoundationApplication(require_once 'config.php');
$accessToken = $wechat->access_token;
$token = $accessToken->getToken();

2. Generate sharing link

Through the API provided by EasyWeChat, we can generate customized sharing links. In the following code, we generate a link to share the circle of friends:

$shareLink = 'https://api.weixin.qq.com/cgi-bin/wxaapp/createwxaqrcode?access_token='.$token.'&path=pages/index/index&scene=123';

The path parameter is used to specify the page path of the mini program, and the scene parameter is used to specify the scene value.

3. Call the WeChat interface

Finally, we need to call the WeChat interface to share. In the following code, we use PHP's curl library to send a POST request:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token='.$token);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode([
    'touser' => 'OPENID',
    'msgtype' => 'news',
    'news' => [
        'articles' => [
            [
                'title' => '分享标题',
                'description' => '分享描述',
                'url' => $shareLink,
                'picurl' => '分享图片URL',
            ],
        ],
    ],
], JSON_UNESCAPED_UNICODE));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);

Replace OPENID with the user's openid, title, description, url and picurl are the shared title, description, link and image URL respectively .

4. Summary

Through the combination of EasyWeChat and PHP, we can easily realize the sharing function of WeChat applet. In this article, we introduce how to configure EasyWeChat, obtain access_token, generate sharing links and call the WeChat interface. I hope these tips can be helpful to your WeChat mini program development.
