【问题描述】：

我在 php 中创建一个简单的 web 应用程序，它使用 paypal 的 adaptivePayments/Pay Api，我使用 POSTMAN 进行了一些测试，一切正常，我发出初始请求，我得到了我的 payKey，也有了这个 payKey，我可以使用 /AdaptivePayments/PaymentDetails Api 检查交易状态，问题是当我尝试通过 php 代码发出请求时：

    $endpoint = 'https://svcs.sandbox.paypal.com/AdaptivePayments/Pay';

    $payload['actionType']                       = "PAY";
    $payload['clientDetails']['applicationId']   = "APP-80W284485P519543T";
    $payload['clientDetails']['ipAddress']       = "xxx.xxx.xxx.xxx";
    $payload['currencyCode']                     = "USD";
    $payload['feesPayer']                        = "EACHRECEIVER";
    $payload['memo']                             = "Transaction";
    $payload['receiverList']['receiver']         = $receivers;
    $payload['requestEnvelope']['errorLanguage'] = "en_US";
    $payload['returnUrl']                        = "URL";
    $payload['cancelUrl']                        = "URL";

    $json = json_encode($payload);

    $ch = curl_init($endpoint);

    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'X-PAYPAL-SECURITY-USERID: ACCOUNT',
        'X-PAYPAL-SECURITY-PASSWORD: PASSWORD',
        'X-PAYPAL-SECURITY-SIGNATURE: SIGNATURE',
        'X-PAYPAL-REQUEST-DATA-FORMAT: JSON',
        'X-PAYPAL-RESPONSE-DATA-FORMAT: JSON',
        'X-PAYPAL-APPLICATION-ID: APP-80W284485P519543T',
        'Content-Type: application/json',
        'Content-Length: ' . strlen($json)
    ));

    $result = curl_exec($ch);

$receivers 是一个 PHP 数组，其中包含有关电子邮件和付款金额的信息，如下所示：

Array
(
    [0] => Array
        (
            [amount] => 19.8
            [email] => [e-mail]
            [primary] => 
        )


    [1] => Array
        (
            [amount] => 20.7
            [email] => [e-mail]
            [primary] => 
        )


    [2] => Array
        (
            [amount] => 45
            [email] => [e-mail]
            [primary] => 1
        )
    )

我没有收到任何错误，我什至得到了用于创建 html 按钮的 payKey，以便用户可以为他的商品付款，问题是当我检查付款状态 /AdaptivePayments/PaymentDetails 时，我得到：

    "responseEnvelope": 
        "timestamp": "2015-08-06T23:59:23.075-07:00",
        "ack": "Success",
        "correlationId": "bab22ca0bd887",
        "build": "17603431"
    ,
    "cancelUrl": "https://23410a33.ngrok.com/universal-bank-of-souls/",
    "currencyCode": "USD",
    "paymentInfoList": null,
    "returnUrl": "https://23410a33.ngrok.com/universal-bank-of-souls/",
    "status": "CREATED",
    "payKey": "AP-8ML17897XK803351A",
    "actionType": "PAY",
    "feesPayer": "EACHRECEIVER",
    "sender": 
        "useCredentials": "false"
    

由于某种奇怪的原因，paypalInfoList 为空，因此用户在单击 paypal 按钮时会看到错误（交易错误）。

正如我之前所说，如果我使用 POSTMAN 进行交易，然后检查状态，我会得到正确的响应：

    "responseEnvelope": 
        "timestamp": "2015-08-07T00:14:08.510-07:00",
        "ack": "Success",
        "correlationId": "b9049ba0d4cf1",
        "build": "17603431"
    ,
    "cancelUrl": "URL",
    "currencyCode": "USD",
    "memo": "Bank of souls payment",
    "paymentInfoList": 
        "paymentInfo": [
            
                "receiver": 
                    "amount": "123.30",
                    "email": "[e-mail]",
                    "primary": "false",
                    "paymentType": "SERVICE",
                    "accountId": "SLKM4ZQ5FMSHG"
                ,
                "pendingRefund": "false"
            ,
            
                "receiver": 
                    "amount": "510.30",
                    "email": "[e-mail]",
                    "primary": "false",
                    "paymentType": "SERVICE",
                    "accountId": "8PUDR7LSRS4MJ"
                ,
                "pendingRefund": "false"
            ,
            
                "receiver": 
                    "amount": "704.00",
                    "email": "[e-mail]",
                    "primary": "true",
                    "paymentType": "SERVICE",
                    "accountId": "E29BAQX7C7P3N"
                ,
                "pendingRefund": "false"
            
        ]
    ,
    "returnUrl": "URL",
    "status": "CREATED",
    "payKey": "AP-9MU4806743660523S",
    "actionType": "PAY",
    "feesPayer": "EACHRECEIVER",
    "reverseAllParallelPaymentsOnError": "false",
    "sender": 
        "useCredentials": "false"
    

（paymentInfoList实际上包含一个json对象与货物，但这是使用POSTMAN手动请求）

这可能是 PHP 问题吗？一些调试 curl 连接的想法会对我有很大帮助。

PD：我一整天都在调试这个，我什至打印了 $json 变量（我得到了 json 格式）并直接在邮递员及其作品中复制/粘贴，但由于某种原因，使用 curl 的相同请求不是发送 $receivers 信息。

【问题讨论】：

看起来交易根本没有完成。这就是为什么它仍然显示已创建。获得 PayKey 后，您必须将用户重定向到 PayPal，以便他们可以登录并完成付款（除非您使用的是预先批准密钥，但我看不到您是。）您是否正在执行重定向并实际完成付款？

【参考方案1】：

已解决，我正在使用两个不同的 api 凭据发出请求（创建订单和请求订单信息），而且，当接收到与原始不同的 api 凭据时，paypal 似乎隐藏了订单商品，但仍显示状态订单的（创建、完成等）
