调用QQ登录接口,首先要到QQ互联完善开发者认证信息,并通过审核,然后创建一个网站应用,获得APP ID和APP Key,通过审核后即可调用基本接口get_user_info(获得用户信息),实现QQ登录网站功能。
废话不多,上示例代码(QQ登录李维山博客):
<?php header("Content-Type: text/html;charset=utf-8"); //应用APP ID $app_id = "101486017"; //应用APP Key $app_secret = "13a1811780f29d7a5b64e598c38a4494"; //应用填写的网站回调域 $my_url = "http://www.msllws.top/qqlogin"; //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='".$dialog_url."'</script>"); } //Step2:通过Authorization Code获取Access Token if($_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); //如果用户临时改变主意取消登录,返回true!==false,否则执行step3 if (strpos($response, "callback") !== false) { $lpos = strpos($response, "("); $rpos = strrpos($response, ")"); $response = substr($response, $lpos + 1, $rpos - $lpos -1); $msg = json_decode($response); if (isset($msg->error)) { echo "<h3>error:</h3>".$msg->error; echo "<h3>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['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($user->error)) { echo "<h3>error:</h3>".$user->error; echo "<h3>msg :</h3>".$user->error_description; exit; } //Step4:使用openid和access_token获取用户信息 $user_data_url = "https://graph.qq.com/user/get_user_info?access_token={$params['access_token']}&oauth_consumer_key={$app_id}&openid={$user->openid}&format=json"; $user_data = file_get_contents($user_data_url);//获取到的用户信息 //以下为授权成功后的自定义操作 if($user_data){ // ...... echo("<script> top.location.href='http://www.msllws.top'</script>"); }else{ echo '未知错误'; } }else{ echo("The state does not match. You may be a victim of CSRF."); }
