我正尝试使用QPX Express API来为我的网站搜索航班。

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

我不知道如何运行

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

从我的PHP文件

。我应该如何管理json文件。我应该做一个PHP文件并设置标题类型，我是否正确？

我找不到任何地方

任何你不需要创建和保存一个实际的JSON文件为每个请求。您可以简单地创建一个JSON字符串并将其作为POST有效负载发送。就执行curl而言，您应该看到PHP Manual中的本地函数。具体而言，curl_init(),curl_setopt()和curl_exec()。下面是一个例子...

$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); 

你也可以使用一个数组来创造有效载荷，然后用json_encode()将其转换成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" 
      ) 
     ) 
    ) 
); 

然后用

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