Google QPX Express API PHP

Question

我正嘗試使用QPX Express API來爲我的網站搜索航班。

https://developers.google.com/qpx-express/v1/requests#Examples

我不知道如何運行

curl -d @request.json --header "Content-Type: application/json" https://www.googleapis.com/qpxExpress/v1/trips/search?key=xxxxxxxxxxxxxx 

從我的PHP文件

。我應該如何管理json文件。我應該做一個PHP文件並設置標題類型，我是否正確？

我找不到任何地方

任何你不需要創建和保存一個實際的JSON文件爲每個請求。您可以簡單地創建一個JSON字符串並將其作爲POST有效負載發送。就執行curl而言，您應該看到PHP Manual中的本地函數。具體而言，curl_init(),curl_setopt()和curl_exec()。下面是一個例子...

$url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=YOUR_API_KEY_HERE"; 

$postData = '{ 
    "request": { 
    "passengers": { 
     "adultCount": 1 
    }, 
    "slice": [ 
     { 
     "origin": "BOS", 
     "destination": "LAX", 
     "date": "2016-05-10" 
     }, 
     { 
     "origin": "LAX", 
     "destination": "BOS", 
     "date": "2016-05-15" 
     } 
    ] 
    } 
}'; 

$curlConnection = curl_init(); 

curl_setopt($curlConnection, CURLOPT_HTTPHEADER, array("Content-Type: application/json")); 
curl_setopt($curlConnection, CURLOPT_URL, $url); 
curl_setopt($curlConnection, CURLOPT_POST, TRUE); 
curl_setopt($curlConnection, CURLOPT_POSTFIELDS, $postData); 
curl_setopt($curlConnection, CURLOPT_FOLLOWLOCATION, TRUE); 
curl_setopt($curlConnection, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($curlConnection, CURLOPT_SSL_VERIFYPEER, FALSE); 

$results = curl_exec($curlConnection); 

你也可以使用一個數組來創造有效載荷，然後用json_encode()將其轉換成JSON字符串。

$postData = array(
    "request" => array(
     "passengers" => array(
      "adultCount" => 1 
     ), 
     "slice" => array(
      array(
       "origin" => "BOS", 
       "destination" => "LAX", 
       "date" => "2016-05-10" 
      ), 
      array(
       "origin" => "LAX", 
       "destination" => "BOS", 
       "date" => "2016-05-15" 
      ) 
     ) 
    ) 
); 

然後用

curl_setopt($curlConnection, CURLOPT_POSTFIELDS, json_encode($postData));
