与 PayPal 连接：获取状态 4​​00（错误请求）

Question

在根据访问代码获取访问令牌期间，我面临来自 PayPal 的 400 个错误请求响应。我通过以下参考链接https://developer.paypal.com/docs/connect-with-paypal/integrate/#1-create-the-app

我完美地遵循了 5 个步骤，但在第 1 步中遇到了问题。6. 看下面我的代码：

请求部分：

$curl = curl_init();

$base_token = "{client_id:secret}";

$data = array(

    CURLOPT_URL => "https://api.sandbox.paypal.com/v1/oauth2/token",

    CURLOPT_RETURNTRANSFER => true,

    CURLOPT_CUSTOMREQUEST => "POST",

    CURLOPT_POSTFIELDS => array(

        'grant_type' => 'authorization_code',

        'code' => '{authorization_code}'

    ),

    CURLOPT_HTTPHEADER => array(

        "Authorization: Basic ".$base_token,

    ),

);

curl_setopt_array($curl,$data );

$response = curl_exec($curl);

curl_close($curl);

响应部分：

stdClass Object (

    [name] => Bad Request

    [debug_id] => 5837077aa8787

    [message] => java.lang.IllegalArgumentException

    [details] => Array

        (

        )

)

Answer 1

解决问题见我下面的代码：$base_token = '{client_id:secret}';$curl = curl_init();$data = array(    CURLOPT_URL => "https://api.sandbox.paypal.com/v1/oauth2/token",    CURLOPT_RETURNTRANSFER => true,    CURLOPT_CUSTOMREQUEST => "POST",    CURLOPT_SSL_VERIFYPEER => false,    CURLOPT_POSTFIELDS => http_build_query(array(        'grant_type'=>'authorization_code',        'code'=> $request->code,    )),    CURLOPT_HTTPHEADER => array(        "Content-Type: application/x-www-form-urlencoded",    ),    CURLOPT_USERPWD => $base_token);curl_setopt_array($curl, $data);$response = curl_exec($curl);curl_close($curl);

Answer 2

将数组传递给 CURLOPT_POSTFIELDS 会将内容类型设置为multipart/form-data. 这是错误的。您需要将查询字符串传递给 CURLOPT_POSTFIELDS。CURLOPT_POSTFIELDS => http_build_query(array(        'grant_type' => 'authorization_code',        'code' => '{authorization_code}'    )),
