HTTP/1.1 400 错误请求 Sabre REST Api

Question

目前正在使用 Sabre Dev Studio 的测试开发者帐户并尝试使用他们的 REST Api - Instaflights_Search.

我正在创建身份验证并获得访问令牌，但当我尝试发送请求时出现问题。我正在使用 curl 和 php.

创建 headers

function callRestApi($url,$access_token) {

    $ch = curl_init();

    $header = array();
    $header[] = "Authorization: Bearer " .$access_token;
    $header[] = "Accept: application/json";
    $header[] =  'Content-Type: application/json';

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_HTTPGET, 1);
    curl_setopt($ch, CURLOPT_VERBOSE, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $result = curl_exec($ch);
    curl_close($ch);
    return json_decode($result,true);
}


$url = "https://api.test.sabre.com/v1/shop/flights?origin=JFK&destination=LAX&departuredate=2016-05-30&returndate=2016-05-31";

$access_token = callForToken();

$server_response = callRestApi($url,$access_token);

Saber 的回应是：

   array(5) {
     ["status"]=>
     string(12) "NotProcessed"
     ["type"]=>
     string(10) "Validation"
     ["errorCode"]=>
     string(30) "ERR.2SG.CLIENT.INVALID_REQUEST"
     ["timeStamp"]=>
     string(29) "2016-05-19T22:36:51.041-05:00"
     ["message"]=>
     string(60) "Request is invalid: The request should have the JSON payload"
    }

并且 HTTP 1/1 请求 header 读取为：

*   Trying 151.193.52.94...

知道 header 有什么问题吗？

编辑于 2016 年 5 月 23 日 构建请求 header 的更正版本如下：

     function callRestApi($url,$access_token) {

      $header2 = array(
      'Authorization : Bearer '.$access_token,
      'Accept : */*'
      );

      $ch = curl_init();
      curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
      curl_setopt($ch, CURLOPT_VERBOSE, true);
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
      curl_setopt($ch, CURLOPT_URL, $url);
      curl_setopt($ch, CURLOPT_HTTPHEADER, $header2);
      $result = curl_exec($ch);
      curl_close($ch);
      return json_decode($result,true);
   }

Answer 1

嗯，我发现有两件事可能会为您指明正确的方向：

Sabre 响应中的错误消息提到缺少 JSON 有效载荷。作为请求的一部分，您是否有意省略数据？（有些服务写得不好，需要一个主体，即使它是空的（“{}”）。）
也许他们的 API 坏了？如果您查看 HTTP 请求（在您的第二个块中），请注意 URL 是如何更改的？指定的 return 日期变量甚至无效（您提供了“2016-05-31”并且它更改（自动重定向？）为“2016-05-315”。也就是说，除非您 copy/pasted 来自两个不同的请求。

希望对您有所帮助。

Answer 2

您是否看过 Sabre github 存储库中的 php 示例代码？

https://github.com/SabreDevStudio/SACS-Php

它使用 IntaFlights 和 curl，因此它可能提供了一种方法来处理您正在测试的 API 和您的环境。
