PayPal Orders v2：请求格式不正确、语法不正确或违反架构

Question

我正在尝试使用 PayPal API。以下是 Curl 用法的参考：https://developer.paypal.com/docs/api/orders/v2/

在 google 中搜索后，我发现 link 显示了类似的错误：但是，没有给出修复它的提示。 https://www.paypal-community.com/t5/REST-APIs/Request-is-not-well-formed-syntactically-incorrect-or-violates/td-p/2090480

我在 PHP 和 Laravel

中有以下代码

$client = new \GuzzleHttp\Client();
$response = $client->request('POST', $uri, [
        'headers' => [
            'Accept' => 'application/json',
            'Accept-Language' => 'en_US',
            'Content-Type' => 'application/json',
            'Authorization' => "Bearer " . $this->token
        ],
        'form_params' => [
            "intent" => "CAPTURE",
            "purchase_units" => [
                "amount" => [
                    "currency_code" => "USD",
                    "value" => "100.00"
                ]
            ]
        ]
    ]
);

当我运行代码时，出现以下错误

GuzzleHttp\Exception\ClientException Client error: POST https://api.sandbox.paypal.com/v2/checkout/orders resulted in a 400 Bad Request response: {"name":"INVALID_REQUEST","message":"Request is not well-formed, syntactically incorrect, or violates schema.","debug_id (truncated...)

更新 1 - 修改了答案中的代码，但仍然是相同的错误消息

$response = $client->request('POST', $uri, [
        'headers' => [
            'Accept' => 'application/json',
            'Accept-Language' => 'en_US',
            'Content-Type' => 'application/json',
            'Authorization' => "Bearer " . $this->token
        ],
        'form_params' => [
            "intent" => "CAPTURE",
            "purchase_units" => [
                [
                    "amount" => [
                        "currency_code" => "USD",
                        "value" => "100.00"
                    ]
                ]
            ]
        ]
    ]
);

Answer 1

文档说：

purchase_units: array (contains the purchase_unit object) An array of purchase units. Each purchase unit establishes a contract between a customer and merchant. Each purchase unit represents either a full or partial order that the customer intends to purchase from the merchant.

你现在的 purchase_units 是 purchase_unit，不是 purchase_unit 的数组，试试把你的 form_params 改成

[
    "intent" => "CAPTURE",
    "purchase_units" => [
       [ 
          "amount" => [
            "currency_code" => "USD",
            "value" => "100.00"
          ]
       ]
    ]
]

Answer 2

    'form_params' => [

PayPal REST API 不使用表单参数。

您需要发送一个 'json' 数据对象。见 GuzzleHttp client documentation.

Answer 3

下面的代码适合我。

$client = new \GuzzleHttp\Client();
$response = $client->request('POST', $uri, [
        'json' => [
            "intent" => "CAPTURE",
            "purchase_units" => [
                [
                    "amount" => [
                        "currency_code" => "USD",
                        "value" => "100.00"
                    ]
                ]
            ]
        ],
        'headers' => [
            'Accept' => 'application/json',
            'Accept-Language' => 'en_US',
            'Content-Type' => 'application/json',
            'Authorization' => "Bearer " . $this->token
        ]
    ]            
);
