為什么我從 api 收到 400 Bad Request 錯誤

Question

我正在嘗試調用 shiplogic API（基於 AWS），但出現400 Bad Request錯誤。

我嘗試了各種方法來請求來自 AWS API（例如 S3）的響應，我嘗試為 cURL 請求創建自己的簽名，現在我正在嘗試此代碼。

$host = "api.shiplogic.com";
$accessKey = 'AKIA55D****';
$secretKey = 'cx0WDJLNj1Bmn2**';
$requestUrl = 'https://api.shiplogic.com';
$uri = '/tracking/shipments';
$httpRequestMethod = 'GET';
$data = '{"tracking_reference": "M3RPH"}';

require 'AWS/aws-autoloader.php';;
use Aws\Signature\SignatureV4;
use Aws\Credentials\Credentials;
use GuzzleHttp\Client;
use GuzzleHttp\Psr7\Request;
use Psr\Http\Client\ClientInterface;

$signature = new SignatureV4('execute-api', 'af-south-1');
$credentials = new Credentials($accessKey, $secretKey);
$psr7Request = new Request($httpRequestMethod, $requestUrl.$uri, ["content-type"=>"application/json"], $data);
$client = new Client([$requestUrl, 'timeout' => 30]);
$sr = $signature->signRequest($psr7Request, $credentials);
$response = $client->send($sr);
var_dump($response);

簡短的錯誤是： PHP Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: GET https://api.shiplogic.com/tracking/shipments resulted in a 400 Bad Request response: Invalid or incomplete input

完整的錯誤是：

PHP Fatal error:  Uncaught GuzzleHttp\Exception\ClientException: Client error: `GET https://api.shiplogic.com/tracking/shipments` resulted in a `400 Bad Request` response:
Invalid or incomplete input

Answer 1

文檔說您需要在查詢字符串上傳遞tracking_reference參數（就像您對 Postman 所做的那樣）：

https://api.shiplogic.com/tracking/shipments?tracking_reference=G9G

但這不是您的代碼所做的：

$data = '{"tracking_reference": "M3RPH"}';
$psr7Request = new Request($httpRequestMethod, $requestUrl.$uri, ["content-type"=>"application/json"], $data)

異常消息清楚地表明 URL 中缺少該參數：

`GET https://api.shiplogic.com/tracking/shipments` resulted in a `400 Bad Request` response

你應該這樣做：

$psr7Request = new Request($httpRequestMethod, $requestUrl.$uri.'?tracking_reference=M3RPH');

Answer 2

我在使用 Creatio API 時遇到了同樣的問題。 就像您的情況一樣，API 在 Postman 中工作，但在 Z2FEC392304A5C23AC138DA2274 中使用 Curl 時卻沒有。 有時 postman 在 HTTP 請求中發送一些額外的標頭。 在我的例子中，postman 匿名發送了一個cookie header。 所以要檢查這一點：導航到出現在應用程序右側的 Postman 的代碼部分。 選擇 PHP 作為編程語言，它將為您顯示完整的Curl請求。

希望這可以幫助！
