PHP method to implement QQ quick login

Foreword:

PHP implements QQ quick login, listing three methods

Method one: process-oriented, callback address and first trigger login are written on a method page [because of if Make judgment],

Methods 2 and 3: Object-oriented

1. First call the login method and send a request to Tencent,
2. Tencent carries the unique corresponding parameters of this website OPENID, ACCESSTOKEN, return to the corresponding callback page,
3. After the callback page receives Tencent's parameters, it uses these two parameters to issue the corresponding request, such as querying the user's data.
4. Tencent performs corresponding operations, such as returning the user's data to you

Even if you don't understand it, it doesn't matter. Follow my process below to ensure that you can achieve it.

Preliminary preparation:

When using Tencent’s functions, you have to say hello to them!

QQ Internet homepage: http://connect.qq.com/

After entering the website, follow the following operations:

1. Enter the official website

2. Apply to create a [website] application

3. Fill in the information as required

Note the website address: fill in You need to set the URL for quick login, eg: http://www.test.com;

Callback address: After you send QQ quick login, Tencent will give you information, and this information will be accepted on this page. eg: http://www.test.com/accept_info.php

[For detailed application filling, please see the official tips, I will not go into details here]

4. After successful application, complete the information

##Final requirements, obtain APP_ID, APP_KEY

5. Code part:

In Write it in your corresponding PHP file, as follows

Method 1, process-oriented method
Usage method: After configuring $app_id, $app_secret, $my_url, copy the others as they are, and $user_data is the returned login information
Code:

//应用的APPID 
   $app_id = "你的APPID"; 
   //应用的APPKEY 
   $app_secret = "你的APPKEY"; 
   //【成功授权】后的回调地址，即此地址在腾讯的信息中有储存 
   $my_url = "你的回调网址"; 
  
   //Step1：获取Authorization Code 
   session_start(); 
   $code = $_REQUEST["code"];//存放Authorization Code 
   if(empty($code)) 
   { 
    //state参数用于防止CSRF攻击，成功授权后回调时会原样带回 
    $_SESSION['state'] = md5(uniqid(rand(), TRUE)); 
    //拼接URL 
    $dialog_url = "https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id="
     . $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
     . $_SESSION['state']; 
    echo("<script> top.location.href=&#39;" . $dialog_url . "&#39;</script>"); 
   } 
  
   //Step2：通过Authorization Code获取Access Token 
   if($_REQUEST[&#39;state&#39;] == $_SESSION[&#39;state&#39;] || 1) 
   { 
    //拼接URL 
    $token_url = "https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&"
     . "client_id=" . $app_id . "&redirect_uri=" . urlencode($my_url) 
     . "&client_secret=" . $app_secret . "&code=" . $code; 
    $response = file_get_contents($token_url); 
    if (strpos($response, "callback") !== false)//如果登录用户临时改变主意取消了，返回true!==false,否则执行step3 
    { 
     $lpos = strpos($response, "("); 
     $rpos = strrpos($response, ")"); 
     $response = substr($response, $lpos + 1, $rpos - $lpos -1); 
     $msg = json_decode($response); 
     if (isset($msg->error)) 
     { 
      echo "<h3 id="error">error:</h3>" . $msg->error; 
      echo "<h3 id="msg-nbsp">msg :</h3>" . $msg->error_description; 
      exit; 
     } 
    } 
  
    //Step3：使用Access Token来获取用户的OpenID 
    $params = array(); 
    parse_str($response, $params);//把传回来的数据参数变量化 
    $graph_url = "https://graph.qq.com/oauth2.0/me?access_token=".$params[&#39;access_token&#39;]; 
    $str = file_get_contents($graph_url); 
    if (strpos($str, "callback") !== false) 
    { 
     $lpos = strpos($str, "("); 
     $rpos = strrpos($str, ")"); 
     $str = substr($str, $lpos + 1, $rpos - $lpos -1); 
    } 
    $user = json_decode($str);//存放返回的数据 client_id ，openid 
    if (isset($user->error)) 
    { 
     echo "<h3 id="error">error:</h3>" . $user->error; 
     echo "<h3 id="msg-nbsp">msg :</h3>" . $user->error_description; 
     exit; 
    } 
    //echo("Hello " . $user->openid); 
    //echo("Hello " . $params[&#39;access_token&#39;]); 
  
    //Step4：使用<span style="font-family: Arial, Helvetica, sans-serif;">openid,</span><span style="font-family: Arial, Helvetica, sans-serif;">access_token来获取所接受的用户信息。</span> 
    $user_data_url = "https://graph.qq.com/user/get_user_info?access_token={$params[&#39;access_token&#39;]}&oauth_consumer_key={$app_id}&openid={$user->openid}&format=json"; 
      
    $user_data = file_get_contents($user_data_url);//此为获取到的user信息 
    } 
    else
    { 
     echo("The state does not match. You may be a victim of CSRF."); 
    }

Method 2, object-oriented using class QQ_LoginAction.class

Usage method:
1. Correctly configure APPID, APPKEY CALLBACK (callback URL) in QQ_LoginAction.class
2. In the calling method, the code is:

$qq_login = new \Component\QQ_LoginAction();    //引入此类文件即可 
$qq_login->qq_login();          //调用登录方法，向腾讯发出快速登录请求

3. In the callback page, the code is:

$qc = new \Component\QQ_LoginAction(); 
$acs = $qc->qq_callback();<span style="white-space:pre">    //access_token 
$oid=$qc->get_openid();<span style="white-space:pre">     //openid 
$user_data = $qc->get_user_info();<span style="white-space:pre">  //get_user_info()为获得该用户的信息，其他操作方法见API文档

4. $user_data is the returned user data.

Method three, object-oriented using the SDK provided by Tencent

Usage method: Tencent SDK, the API is very well written Detailed, no details
Address: http://wiki.connect.qq.com/%E7%BD%91%E7%AB%99%E6%8E%A5%E5%85%A5%E6%A6 %82%E8%BF%B0

In this way, QQ quick login is achieved. It is actually very simple. You can give it a try.

If you are still unclear, you can read the official introduction for more details.

Tips: How to test QQ quick login locally

Method: Modify the HOST configuration file
1. Open C :\Windows\System32\drivers\etc\host
2. Add 127.0.0.1 www.test.com
and then operate.

The above is the entire content of this article. I hope it will be helpful to everyone's learning. I also hope that everyone will support the PHP Chinese website.
