Implement cloud development of WeChat mini programs using ThinkPHP6

With the continuous development of Internet technology, the importance of mobile Internet has attracted more and more attention. WeChat Mini Program is a mobile application that has become popular in recent years. More and more companies and developers choose to use WeChat Mini Program for product promotion and development. WeChat mini program cloud development is a simpler and more efficient way.

ThinkPHP6 is a PHP framework that is efficient, simple, and easy to expand. This article will introduce how to use the ThinkPHP6 framework to implement WeChat applet cloud development.

1. Environment preparation

Before starting, you first need to prepare the following environment:

1. PHP environment: PHP7 and above need to be installed.
2. Composer package manager: used to install the ThinkPHP6 framework and other dependent packages.
3. MySQL database: used to store application data.
4. WeChat Developer Tools: used to develop and debug WeChat applets.

2. Install the ThinkPHP6 framework

1. Install the Composer package manager.
2. Create a new project and install the ThinkPHP6 framework:

Enter the project folder through the command line and enter the following command to install the ThinkPHP6 framework:

composer create-project topthink /think tp6 --prefer-dist

3. After the installation is completed, start the local server through the command line:

php think run

4. Open the browser and visit http://localhost:8000. If you can see the welcome page of the ThinkPHP6 framework, the installation is successful.

3. Configure the WeChat Mini Program Cloud Development Environment

1. Register a WeChat developer account, create a new Mini Program, and obtain the AppID and AppSecret.
2. Log in to the WeChat applet management platform and create an environment in the cloud development console.
3. Create a database in the environment and add the required collections (similar to tables in MySQL).

4. Create a file env.php in your local development environment (this file should not be under git version control).

   return [

    // 微信小程序配置
    'appid'     => 'wx***',
    'secret'    => '***',
   
    // 微信小程序云开发环境配置
    'env'       => '***',
   

   ];

5. Install and configure EasyWeChat SDK: API for accessing WeChat mini programs.

Enter the following command on the command line to install EasyWeChat SDK:

composer require overtrue/wechat

Create the file config/wechat.php, configure AppID, AppSecret and others Related Information.

use EasyWeChatFactory;

$options = [

'app_id'        => 'wx***',
'secret'        => '***',
'response_type' => 'array',
'log'           => [
    'level' => 'debug',
    'file'  => '/path/to/easywechat.log',
],

];

$app = Factory::officialAccount($ options);

4. Write business logic code

1. Create controller

The controller file in the ThinkPHP6 framework is placed in the app/controller directory . Create a new controller through the CLI command line, for example:

php think make:controller Index

2. Write business logic code

Next , write the required business logic code in the Index controller. For example, obtain user information from the background of the WeChat applet and add it to the database:

namespace appcontroller;

use think acadeConfig;
use think acadeDb;
use EasyWeChatFactory;

class Index
{

public function addUserInfo()
{
    // 获取微信用户信息
    $wechat_user = Factory::officialAccount(Config::get('wechat'))->oauth->user();
    
    // 插入用户数据
    $result = Db::name('user')->insert([
        'openid' => $wechat_user->getId(),
        'nickname' => $wechat_user->getNickname(),
        'avatar' => $wechat_user->getAvatar(),
    ]);

    if($result)
        return 'success';
    else
        return 'fail';
}

}

In the above code, user information is obtained through EasyWeChat SDK, and then through the DB operation mechanism of ThinkPHP6 Insert user information into the database.

3. Writing API interface

In the WeChat applet, the business logic code needs to be provided to the front-end for calls through the API interface. In ThinkPHP6, API interfaces can be written through methods in the controller.

For example, add the addUserInfo method in the Index controller to insert the user information obtained from the WeChat applet background into the database. In this controller, write the following code in the addUserInfo method:

public function addUserInfo()
{

// 获取微信用户信息
$wechat_user = Factory::officialAccount(Config::get('wechat'))->oauth->user();

// 插入用户数据
$result = Db::name('user')->insert([
    'openid' => $wechat_user->getId(),
    'nickname' => $wechat_user->getNickname(),
    'avatar' => $wechat_user->getAvatar(),
]);

if($result)
    return json(['message' => 'success', 'data' => []]);
else
    return json(['message' => 'fail', 'data' => []]);

}

The returned result is in json format , which is convenient for the WeChat applet front-end to receive and parse.

4. Summary

This article introduces how to use the ThinkPHP6 framework to implement WeChat applet cloud development. Generally speaking, this is a relatively efficient and convenient development method. Of course, if you want to have a deeper understanding of this technology, you still need continuous learning and practice.

The above are just some simple code examples. In real development, many factors need to be considered, such as data security, code readability and reusability, etc. I hope that while reading this article, readers can also practice and develop better WeChat applet cloud development applications.
