错误的卷曲用POST数据

Question

我想从这个URL使用PHP卷曲提取数据：

https://www.traveloka.com/en/flight/fullsearch?ap=JKTA.DPS&dt=14-10-2017.NA&ps=1.0.0&sc=ECONOMY

但我得到了以下错误：

"{"errorType":"SERVER_ERROR","userErrorMessage":"Unexpected server error occurred. We apologize for the inconvenience. Please try again later.","errorMessage":"Exception occurred in server."}".

我怎样才能提取数据从该链接与PHP卷曲？

这里是我的代码

$url = 'https://api.traveloka.com/en/v2/flight/search/oneway';    

$params = [ 
    'context' => [

$ch = curl_init($url);                  
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);   
curl_setopt($ch, CURLOPT_AUTOREFERER, true); 
curl_setopt($ch, CURLOPT_HEADER, false); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
curl_setopt($ch, CURLOPT_POST, 1);  
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params));                       
curl_setopt($ch, CURLOPT_REFERER, "https://www.traveloka.com/en/flight/fullsearch?ap=JKTA.DPS&dt=14-10-2017.NA&ps=1.0.0&sc=ECONOMY"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_VERBOSE, true); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                   
    "Host: api.traveloka.com",   
    "Accept: application/json, text/javascript, */*; q=0.01", 
    "Accept-Language: en-us,en;q=0.5", 
    "X-Requested-With: XMLHttpRequest",   
    "Connection: keep-alive", 
    "Pragma: no-cache", 
    "Cache-Control: no-cache")                  
);     

$result = curl_exec($ch); 

print_r($result); 

curl_close($ch);  

其实我没有做屏幕抓取，但我想抓取其中的JSON数据。我在浏览器中打开“网络”选项卡并查看XHR部分，然后我想从该XHR部分获取响应。那么如何做到这一点，我的代码有什么问题？

Answer 1

你想要做的就是所谓的Web报废，有很多工具可以用来做到这一点。 现在，请执行： https://github.com/FriendsOfPHP/Goutte 或https://github.com/duzun/hQuery.php。

按网址你给使用下面的代码，你会得到什么，而重定向链接：

使用curl的一般格式为：

与链接和参数与正确的API替换在这里给出：

  $ch = curl_init(); 

      $params = urldecode('{"ap":"' . 'JKTA.DPS' . '","dt":"' . '14-10-2017.NA' . '","ps":"' . '1.0.0'. '","sc":"' . 'ECONOMY'. '"}'); 



      $url = 'https://www.traveloka.com/en/flight/fullsearch?JsonData=' . $params; 
      curl_setopt($ch, CURLOPT_URL, $url); 
      curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
      // curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0"); 

      curl_setopt($ch, CURLOPT_HEADER, 0); 

      // Should cURL return or print out the data? (true = return, false = print) 
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

      // Timeout in seconds 
      curl_setopt($ch, CURLOPT_TIMEOUT, 10); 

      // Download the given URL, and return output 
      $output = curl_exec($ch); 

      // Close the cURL resource, and free system resources 
      curl_close($ch); 

      if (!empty($output)) { 
       $x = json_decode($output, true); 
         var_dump($x); 
        }else{ 
         return FALSE; 
        }
