最近做跨境电子商务程序的第三方登录用到了PayPal登录，发上来给需要的人。<?php <br />
namespace Home\Controller;<br>
use Think\Controller;<br>
class User extends Controller{<br>
public function paypal(){<br>
$_SESSION['state'] = md5(uniqid(rand(), TRUE)); <br>
$client_id = '你的client_id';<br>
$client_secret = '你的client_secret';<br>
$nonce = time() . rand();<br>
$app_return_url = 'http://yourdomain/user/paypal_return'; //这里的返回地址必须要与你在paypal上创建client_id时填写的返回地址一致<br>
$scopes = 'profile+email+address+phone';<br>
$paypal_auth_url = "https://www.paypal.com/webapps/auth/protocol/openidconnect/v1/authorize?"<br>
."client_id=".$client_id<br>
."&response_type=code"<br>
."&scope=".$scopes<br>
."&nonce=".$nonce<br>
."&state=".$_SESSION['state']<br>
."&redirect_uri=".urlencode($app_return_url);<br>
//echo $paypal_auth_url;exit;<br>
header("Location: $paypal_auth_url"); <br>
}<br>
<br>
/**<br>
* Paypal返回地址<br>
* @return void<br>
*/<br>
public function paypal_return(){<br>
$code = trim($_GET['code']);<br>
<br>
$client_id = '你的client_id';<br>
$client_secret = '你的client_secret';<br>
//根据授权码获取到access_token <br>
if(!isset($_SESSION['access_token'])){ <br>
$token_url = "https://www.paypal.com/webapps/auth/protocol/openidconnect/v1/tokenservice"; <br>
$postvals = "client_id=".$client_id<br>
."&client_secret=".$client_secret<br>
."&grant_type=authorization_code"<br>
."&code=".$code;<br>
$response = Http::fsockopenDownload($token_url,array(<br>
'post' => $postvals,<br>
));<br>
$atoken = json_decode($response);<br>
$access_token = $atoken->access_token;<br>
$_SESSION['access_token'] = $access_token; //token可以保存起来使用，貌似15分钟后才会失效<br>
}<br>
//获取到用户资料<br>
$profile_url = "https://www.paypal.com/webapps/auth/protocol/openidconnect/v1/userinfo?"<br>
."schema=openid"<br>
."&access_token=".$_SESSION['access_token'];<br>
$profile = file_get_contents($profile_url);<br>
$profile = json_decode($profile);<br>
if(isset($profile->error)){<br>
exit($profile->message);<br>
}<br>
//注意：有些资料不一定会返回<br>
$email = $profile->email;<br>
$name = $profile->name;<br>
$first_name = $profile->family_name;<br>
$last_name = $profile->given_name;<br>
$phone = $profile->phone_number;<br>
$locale = $profile->locale;<br>
$address = $profile->address;<br>
}<br>
}<br>
