Amadeus Flight Search API在curl PHP中传递access_token时出错

如何解决Amadeus Flight Search API在curl PHP中传递access_token时出错

我正在集成amadeus飞行搜索api并在使用access_token时出错。我猜问题出在获取访问令牌吗？

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

我需要获得所有从来源到目的地的航班，并提供价格详细信息。

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

解决方法

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：

对于使用的PHP版本，您需要添加curl_setopt($curls,CURLOPT_RETURNTRANSFER,true);以确保它不仅打印API响应，而且还返回它（请参见this post）
您需要在Bearer和访问令牌之间留一个空格：array('Authorization: Bearer ' .$data['access_token']));
您尝试调用的示例是错误的，返回日期早于脱离日期。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 reference documentatio n来了解您可以使用的不同查询参数。
在进行API调用之前，您需要将CURLOPT_POST更改为false（因为您要调用的API是GET）

在完整的示例下面查找：

$curls = curl_init();
curl_setopt($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,true);
$token = curl_exec($curls);
$data = json_decode($token,true);

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

curl_setopt($curls,array('Authorization: Bearer ' .$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，我相信代码可以改进。
