前言:

PHP实现QQ快速登录,罗列了三种方法

方法一:面向过程,回调地址和首次触发登录写到了一个方法页面【因为有了if做判断】,

方法二,三:面向对象

1.先调用登录方法,向腾讯发送请求,
2.腾讯携带本网站唯一对应参数OPENID,ACCESSTOKEN,返回到对应回调页面,
3.回调页面接受到腾讯的参数后,通过这个两个参数,再发出对应的请求,如查询用户的数据。
4.腾讯做出对应的操作,如返回这个用户的数据给你

即使你没看懂,也没关系,按照我下面的流程来,保证你可以实现。

前期准备:

使用人家腾讯的功能,总得和人家打招呼吧!

QQ互联首页:http://connect.qq.com/

进入网址后,按如下操作来:

一.进入官网


二.申请创建【网站】应用


三.按要求填写资料

注意网站地址:填写你要设置快速登录的网址,eg:http://www.test.com;

回调地址:填写你发送QQ快速登陆后,腾讯得给你信息,这个信息往此页面接受。eg:http://www.test.com/accept_info.php

【详细的申请填写,请见官方提示,这里不做赘述】


四.申请成功后,完善信息

最终要求,获得APP_ID ,APP_KEY

五.代码部分:

在你对应的PHP文件内写入,如下
方法一,面向过程法
使用方法:配置$app_id,$app_secret,$my_url后,其他原封复制即可,$user_data为返回的登录信息
代码:

//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(""); 
   } 
 
   //Step2:通过Authorization Code获取Access Token 
   if($_REQUEST['state'] == $_SESSION['state'] || 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 "

error:

" . $msg->error; echo "

msg :

" . $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['access_token']; $str = file_get_contents($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 "

error:

" . $user->error; echo "

msg :

" . $user->error_description; exit; } //echo("Hello " . $user->openid); //echo("Hello " . $params['access_token']); //Step4:使用openid,access_token来获取所接受的用户信息。 $user_data_url = "https://graph.qq.com/user/get_user_info?access_token={$params['access_token']}&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."); }

方法二,面向对象 使用类QQ_LoginAction.class
使用方法:
1.在QQ_LoginAction.class中正确配置 APPID,APPKEY CALLBACK(回调网址)
2.在调用方法中,代码:

$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.在回调页面中,代码:

$qc = new \Component\QQ_LoginAction(); 
$acs = $qc->qq_callback();    //access_token 
$oid=$qc->get_openid();     //openid 
$user_data = $qc->get_user_info();  //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即为返回的用户数据。
5.QQ_LoginAction.class.php 文件代码:【用的ThinkPHP3.2】

<?php 
namespace Component; 
 
session_start(); 
define('APPID','XXXX');   //appid

方法三,面向对象 使用腾讯给的SDK
使用方法:腾讯SDK,API写的很详细,不做赘述
地址:http://wiki.connect.qq.com/%E7%BD%91%E7%AB%99%E6%8E%A5%E5%85%A5%E6%A6%82%E8%BF%B0

这样就实现了QQ快捷登录,其实很简单的,大家可以试一试。
还有什么不清楚的,可以看看官方介绍,更详细,

Tips:如何在本地测试QQ快速登录
方法:修改HOST配置文件
1. 打开C:\Windows\System32\drivers\etc\host
2. 添加127.0.0.1 www.test.com
然后操作就可以了。

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
