为什么我从 api 收到 400 Bad Request 错误

Question

我正在尝试调用 shiplogic API（基于 AWS），但出现400 Bad Request错误。

我尝试了各种方法来请求来自 AWS API（例如 S3）的响应，我尝试为 cURL 请求创建自己的签名，现在我正在尝试此代码。

$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);

简短的错误是： 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

完整的错误是：

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

Answer 1

文档说您需要在查询字符串上传递tracking_reference参数（就像您对 Postman 所做的那样）：

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

但这不是您的代码所做的：

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

异常消息清楚地表明 URL 中缺少该参数：

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

你应该这样做：

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

Answer 2

我在使用 Creatio API 时遇到了同样的问题。 就像您的情况一样，API 在 Postman 中工作，但在 Z2FEC392304A5C23AC138DA2274 中使用 Curl 时却没有。 有时 postman 在 HTTP 请求中发送一些额外的标头。 在我的例子中，postman 匿名发送了一个cookie header。 所以要检查这一点：导航到出现在应用程序右侧的 Postman 的代码部分。 选择 PHP 作为编程语言，它将为您显示完整的Curl请求。

希望这可以帮助！
