curl中的paypal MALFORMED REQUEST错误

Question

我在贝宝API中面临MALFORMED_REQUEST

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://api.sandbox.paypal.com/v1/payments/payment");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{
"intent":"authorize",
"payer":{
    "payment_method":"credit_card",
    "funding_instruments":[{
        "credit_card":{
            "number":"5555555555554444",
            "type":"mastercard",
            "expire_month":07,
            "expire_year":22,
            "cvv2":123,
            "first_name":"FName",
            "last_name":"Lname",
            "billing_address":{
                "line1":"address,",
                "city":"City",
                "state":"state",
                "postal_code":"postal_code",
                "country_code":"country_code"
            }
        }
    }]
},
"transactions":[{
    "amount":{
        "total":"10",
        "currency":"CAD",
        "details":{
            "subtotal":"10",
            "tax":"0",
            "shipping":"0"
        }
    }
}]}");
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array();
$headers[] = "Content-Type: application/json";
$headers[] = "Authorization: Bearer myAccessToken";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);

在这里，我呼叫curl以获得贝宝的授权

jsonlint.com显示此json格式可以

但我仍然得到了类似的回应

{"name":"MALFORMED_REQUEST","message":"The request JSON is not well formed.","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#MALFORMED_REQUEST","debug_id":"9d7454a8637ae"}

没有弄清楚我错在哪里？有人知道吗？提前感谢！

Answer 1

您的问题是"expire_month": 07中的07。我认为这个值应该是一个字符串。不确定您在jsonint中粘贴了什么，但问题中不是JSON。

如注释所示，不要滚动您自己的JSON。使用可用的工具

$data = [
    'intent' => 'authorize',
    'payer' => [
        'payment_method' => 'credit_card',
        'funding_instruments' => [[
            'credit_card' => [
                'number' => '5555555555554444',
                'type' => 'mastercard',
                'expire_month' => '07',
                'expire_year' => '22',
                'hopefully you get the idea' => 'by now'
            ]
        ]]
    ]
];
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));

Answer 2

如错误所示，您的JSON格式不正确。您不需要传递来转义您的请求参数。请尝试删除这些代码或尝试此开箱即用的示例代码。
