php - 使用 cURL 和 PHP 发送 POST 数据以检索航空公司信息

Question

我总是使用 PHP Simple HTML DOM Parser 来制作网页抓取脚本，但这次我需要使用 cURL，因为表单使用 POST，我不知道为什么我的脚本不起作用。

我正在使用 Burp Proxy 来获取所有 POST 信息。

我想使用 cURL 进行查询。

这是函数，我将使用 http://flyfirstnation.com例如:

<?php

function curl_get_contents($url)
{
  $curl_moteur = curl_init();
  curl_setopt($curl_moteur, CURLOPT_URL, $url);
  curl_setopt($curl_moteur, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt ($curl_moteur, CURLOPT_POST, true);
  curl_setopt ($curl_moteur, CURLOPT_POSTFIELDS, '{"FormData":{"Origin":["LOS"],"VarsSessionID":"","Destination":["ABV"],"DepartureDate":["24-Jan-2014"],"ReturnDate":["28-Jan-2014","28-Jan-2014"],"Adults":"1","Children":"0","Seniors":0,"Students":0,"Infants":"0","Youths":0,"Teachers":0,"SeatedInfants":0,"EVoucher":"","SearchUser":"PUBLIC"},"IsMMBChangeFlightMode":false}');


  curl_setopt($curl_moteur,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

  curl_setopt($curl_moteur, CURLOPT_FOLLOWLOCATION, 1);
  $web = curl_exec($curl_moteur);
  curl_close($curl_moteur);
  return $web;
}


echo curl_get_contents('reservations.flyfirstnation.com');

?>

这是我收到的错误消息:

Answer 1

这似乎是 CURLOPT_POSTFIELDS 值的问题，它必须是一个键值 PHP 数组，如下所示:

$postFields = array(
    "FormData" => array(
        "Origin" => array(
        ...
        )
    )
);
