Question

我尝试通过PayPal实现登录。基本上，我只是复制了这个例子：How to Implement User Log-in with PayPal。但是，我收到第二个响应的400 - 错误请求错误（在PayPal登录包含文件中）。我无法做出太多错误，也许有人知道怎么了错的。结果：

我的代码:( ppinit.php只定义常量）

require_once(dirname(__FILE__)."/ppinit.php");

$requestData = '?grant_type=authorization_code&code='.getGet("code").'&return_url=http://localhost/paypal/return';

$response = \Httpful\Request::get("https://" . PAYPAL_API_URL . "/v1/identity/openidconnect/tokenservice" . $requestData)
->authenticateWith(PAYPAL_CLIENT_ID, PAYPAL_CLIENT_SECRET)
->send();

$jsonResponse = json_decode($response->raw_body);

if(isset($jsonResponse->error))
{
    echo "Fehler bei der Anmeldung mit PayPal.";
    echo "<br/>";
    exit;
}
//that's the one that does not work.
$response = \Httpful\Request::get("https://" . PAYPAL_API_URL . "/v1/identity/openidconnect/userinfo/?schema=openid")
->contentType("application/json")
->authorization($jsonResponse->access_token)
->authenticateWith(PAYPAL_CLIENT_ID, PAYPAL_CLIENT_SECRET)
->send();
$ppuser = json_decode($response);

Answer 1

一般来说， HTTP 400错误请求意味着发送的请求格式错误，即客户端发送到服务器的数据流没有遵循规则 - read more

很难说出这些错误的确切来源，因为可能有很多，但我建议你将你的HTTP调用包装在try / catch块中，并追踪错误的原因。因此，在这种情况下，您可以用以下代码替换代码：

try {
    $response = \Httpful\Request::get("https://" . PAYPAL_API_URL . "/v1/identity/openidconnect/tokenservice" . $requestData)
        ->authenticateWith(PAYPAL_CLIENT_ID, PAYPAL_CLIENT_SECRET)
        ->send();
} catch (Exception $e) {
    var_dump($e->getMessage());
    exit(1);
}

如果您正在使用命名空间，请在\之前添加Exception - ＆gt; \Exception

Answer 2

使用下面的代码替换第二个请求。

try 
{
    $params = array('access_token' => $jsonResponse->access_token);
    $userInfo = OpenIdUserinfo::getUserinfo($params, $paypal);

} catch (Exception $ex) 
{
    echo $ex;
    exit(1);
}
