ThinkPHP6 third-party login integration: realize one-click login function

In modern Internet applications, users can log in to applications through third-party platforms, which greatly facilitates users registration and login process. ThinkPHP is a well-known PHP framework, and the integration of third-party login is relatively simple. This article will introduce how to use the ThinkPHP6 framework to implement the one-click login function.

1. Create a third-party application

First, we need to register an application on the target third-party platform to obtain the necessary information such as the application's AppID and AppSecret. This article takes WeChat login as an example. The steps are as follows:

• Log in to the WeChat open platform (https://open.weixin.qq.com/) and register a developer account.
• Create an application on the open platform and obtain the AppID and AppSecret.

2. Install ThinkPHP6 and related dependency packages

Use Composer to install the ThinkPHP6 framework and related dependency packages and run the following command:

composer create-project topthink/think tp6

3. Configure third-party login information

Add the following configuration information to the .env file in the project:

# 微信登录配置
WECHAT_APPID=YOUR_WECHAT_APPID
WECHAT_SECRET=YOUR_WECHAT_SECRET
WECHAT_REDIRECT_URI=YOUR_REDIRECT_URI

Change YOUR_WECHAT_APPID, Replace YOUR_WECHAT_SECRET and YOUR_REDIRECT_URI with the application information you obtained on the WeChat open platform.

4. Create controllers and routes

In ThinkPHP6, we can quickly create controllers and routes through commands. Execute the following command:

php think make:controller ThirdLogin

In the generated controller file, we add the logic of WeChat login and callback methods. The sample code is as follows:

<?php
namespace appcontroller;

use thinkController;
use thinkacadeConfig;

class ThirdLogin extends Controller
{
    // 微信登录
    public function wechatLogin()
    {
        // 构造授权请求URL
        $redirectUri = urlencode(Config::get('app.url') . '/thirdLogin/wechatCallback');
        $url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=" . 
               Config::get('wechat.appid') . 
               "&redirect_uri=" . 
               $redirectUri .
               "&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect";
        
        // 跳转到微信授权页面
        return redirect($url);
    }

    // 微信登录回调
    public function wechatCallback()
    {
        // 获取回调时微信返回的code
        $code = input('get.code');
        
        // 根据code获取access_token
        // ...
        
        // 根据access_token获取用户信息
        // ...
        
        // 登录逻辑
        // ...
    }
}

Then, we need to add routing configuration in the route.php file in the route directory. The sample code is as follows:

<?php
use thinkacadeRoute;

// 第三方登录
Route::get('login/wechat', 'ThirdLogin/wechatLogin');
Route::get('thirdLogin/wechatCallback', 'ThirdLogin/wechatCallback');

5. Implementing the front-end page

In the front-end page, we add a function that jumps to the WeChat login page after clicking a button. The sample code is as follows:

<button onclick="redirect()">微信登录</button>

<script>
    function redirect() {
        window.location.href = '/login/wechat';
    }
</script>

So far, we have completed the one-click login function integrating WeChat login in the ThinkPHP6 framework.

It should be noted that this article is just a simple example. In actual development, you also need to handle error callbacks, logic for obtaining access_token and user information, etc.
