How does PHP realize the opening principle and process of QQ login?

PHP implements the opening principle and process implementation method of QQ login: first log in to QQ and enter the QQ Internet Management Center to create related applications; then obtain the relevant interfaces and download the demo related to QQ Internet; then add the API Copy the folder to the project; finally add the relevant code to the [inc.php] file.

PHP implements the opening principle and process implementation method of QQ login:

1. Enter the QQ Internet official website. Log in (you can use your own QQ or re-register a QQ account as a separate QQ for our project for management)

2. Click "Application Management" to enter the QQ Internet Management Center, where you can create related applications. For website applications and mobile applications. Select the application you want to fill in the information (you need to wait for about 7 days for review). If you pass the review, you will get the APP ID

and APP Key. Please take a small notebook and write it down! Please take a notebook and write it down! Please take a notebook and write it down! (Say important things three times!!!)

3. Obtain the relevant interface after passing the review: get_user_info.

4. Download the demo related to QQ Internet

5. If you look closely at the sdk, we will find that it contains 4 folders and 2 files, the most important of which is the API folder, and the rest I think you can ignore it (it’s okay if you read it). Follow this document step by step, and you can realize the login function.

6. Copy the API folder to your project. As for which folder of the project to copy to, as long as you can import it, it depends on your mood. After the preliminary preparations are done, the next step is to write the code.

7. Open the API folder you copied to the project. There is a comm folder in it. Open comm again and you will see a guy named inc.php . Open it. ! Fill in the APPID and APPKEY recorded above in your notebook into the relevant positions. The approximate form is like this

<?php die(&#39;forbidden&#39;); ?>
{"appid":"你的appid","appkey":"你的appkey","callback":"你的网站回调域","scope":"get_user_info"}

8. The code is as follows

<?php
/**
 * Created by PhpStorm.
 * User: qichao
 * Date: 2018/1/31
 * Time: 下午7:22
 */
namespace wechat\controllers;
use wechat\common\BaseController;
require(__DIR__ . &#39;/../tools/API/qqConnectAPI.php&#39;); //引入QQ互联SDK,这是按照我自己项目的路径引入的。
class QqloginController extends BaseController{
 //登录方法
 public function actionQqlogin(){
  $qc = new \QC();
  $qc->qq_login();
 }
 //这个方法是当你通过QQ登录成功以后想要跳转回来的地址，比如你想登录成功以后跳转到百度，那你把下文的$url改为百度链接即可！
 public function actionCallback(){
  header("Content-type: text/html; charset=utf-8");
　　　　/* 　　　　　　这里请根据你的项目开发需求(比如获取登录用户的昵称、头像、年龄等等)，进行相关代码的开发，具体数据获取方法，请查阅QQ互联文档
  $qc = new \QC();
  $access_token = $qc->qq_callback();
  $openid = $qc->get_openid();
  */
  $url = "http://wechat.xxx.cn/index.php?r=cms/home";
  header("Location:".$url);
  exit();
 }
}
