Amadeus Flight search api 在 curl php 中傳遞 access_token 時出錯

Question

我正在集成 amadeus flight search api 並在使用 access_token 時出錯。 我猜問題在於檢索訪問令牌？

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

我需要獲取從源到目的地的所有航班以及價格詳情。

$curls = curl_init();
curl_setopt($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);

我在您的代碼中發現了一些錯誤並修復了它以使其正常工作：

1. 隨着你使用的PHP版本，需要添加curl_setopt($curls, CURLOPT_RETURNTRANSFER, true); 確保它不僅打印 API 響應，而且還返回它（請參閱此帖子）
2. 您需要在 Bearer 和訪問令牌之間留一個空格： array('Authorization: Bearer ' .$data['access_token']));
3. 您嘗試調用的示例是錯誤的，返回日期早於離開日期。 我將其更改為一個更簡單的示例： 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 。 請查看API 參考文檔以了解您可以使用的不同查詢參數。
4. 在調用 API 之前，您需要將CURLOPT_POST更改為 false （因為您嘗試調用的 API 是GET ）

在下面找到完整的例子：

$curls = curl_init();
curl_setopt($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專家，我相信代碼可以改進。
