php - Amadeus Flight search api在curl php中传递access_token时出错

问题描述

我正在集成 amadeus 航班搜索 api 并在使用 access_token 时出错。我想问题在于检索访问令牌？

{ "errors": [ { "code": "38191", "title": "Invalid HTTP header", "detail": "Missing or invalid format for mandatory Authorization header", "status": "401" } ] }

我需要获取从源头到目的地的所有航班以及价格详情。

$curls = curl_init();
curl_setopt($curls, CURLOPT_URL, 'https://test.api.amadeus.com/v1/security/oauth2/token'); 
curl_setopt($curls, CURLOPT_POST, true);
curl_setopt($curls, CURLOPT_POSTFIELDS, "grant_type=client_credentials&client_id=$secretid&client_secret=$secretkey");
curl_setopt($curls, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
$token = curl_exec($curls);
$data = json_decode($token,true);

curl_setopt($curls, CURLOPT_URL, 'https://test.api.amadeus.com/v2/shopping/flight-offers?originLocationCode=SYD&destinationLocationCode=BKK&departureDate=2020-10-01&returnDate=2020-08-05&adults=2&includedAirlineCodes=TG&max=3');

curl_setopt($curls, CURLOPT_HTTPHEADER, array('Authorization: Bearer' .$data['access_token']));
$result = curl_exec($curls);
    if (curl_errno($curls)) {
        echo 'Error:' . curl_error($curls);
    }
//print_r ($result);
curl_close ($curls);

解决方案

我在您的代码中发现了一些错误并对其进行了修复以使其正常工作：

  1. 对于您使用的 PHP 版本，您需要添加curl_setopt($curls, CURLOPT_RETURNTRANSFER, true);以确保它不仅打印 API 响应，而且还返回它（请参阅这篇文章）
  2. 您需要在 Bearer 和访问令牌之间留一个空格：array('Authorization: Bearer ' .$data['access_token']));
  3. 您尝试调用的示例是错误的，返回日期早于出发日期。我将其更改为一个更简单的示例：https://test.api.amadeus.com/v2/shopping/flight-offers?originLocationCode=EWR&destinationLocationCode=MIA&departureDate=2020-09-10&returnDate=2020-09-17&adults=1&max=1. 请查看API 参考文档以了解您可以使用的不同查询参数。
  4. 在进行 API 调用之前，您需要将 更改CURLOPT_POST为 false （因为您尝试调用的 API 是GET）

在下面找到完整的示例：

$curls = curl_init();
curl_setopt($curls, CURLOPT_URL, 'https://test.api.amadeus.com/v1/security/oauth2/token');
curl_setopt($curls, CURLOPT_POST, true);
curl_setopt($curls, CURLOPT_POSTFIELDS, "grant_type=client_credentials&client_id=$secretid&client_secret=$secretkey");
curl_setopt($curls, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($curls, CURLOPT_RETURNTRANSFER, true);
$token = curl_exec($curls);
$data = json_decode($token,true);

curl_setopt($curls, CURLOPT_URL, 'https://test.api.amadeus.com/v2/shopping/flight-offers?originLocationCode=EWR&destinationLocationCode=MIA&departureDate=2020-09-10&returnDate=2020-09-17&adults=1&max=1');
curl_setopt($curls, CURLOPT_POST, false);

curl_setopt($curls, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' .$data['access_token']));
$result = curl_exec($curls);
    if (curl_errno($curls)) {
        echo 'Error:' . curl_error($curls);
    }
print_r ($result);
curl_close ($curls);

注意：我不是 PHP 专家，我确​​信代码可以改进。
