curl中的paypal MALFORMED REQUEST错误 - paypal MALFORMED REQUEST error in curl

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！

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));

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。
