如何使用PHP CURL模拟Ajax请求？ [英] How to emulate Ajax request using PHP CURL?

问题描述

当我发送带有CURL的Ajax请求时，我的代码是400 http_code错误。

I am getting 400 http_code error when I send a Ajax request with CURL below is my Code.

    $header = array(
    "Accept : application/json, text/javascript, */*; q=0.01",
    "Accept-Encoding : gzip, deflate",
    "Accept-Language : en-US,en;q=0.5",
    "Content-Type : application/json; charset=UTF-8",
    "Host : https://some.com",
    "Referer : https://some.com/dashboard/reports",
    "X-Requested-With : XMLHttpRequest"
     );
    $c      = curl_init('https://domain.com/report.php');
    //curl_setopt($c, CURLOPT_SSL_VERIFYPEER, false);
    //curl_setopt($c, CURLOPT_VERBOSE, true);

    curl_setopt($c, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
    curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt( $c, CURLOPT_POST, true );
    curl_setopt( $c, CURLOPT_POSTFIELDS, $data_url );
    curl_setopt($c, CURLOPT_HTTPHEADER, $header);
    //curl_setopt($ch, CURLOPT_HTTPHEADER, array("X-Requested-With: XMLHttpRequest"));

    curl_setopt($c, CURLOPT_COOKIEFILE, $cookie_jar);
    $page     = curl_exec($c);
    $httpcode = curl_getinfo($c);

//我在发出Curl请求后得到以下响应

// I am getting following response after making Curl request

推荐答案

我不确定是否会帮助您，但我能够使用以下代码成功查询SSL网站。
用户代理，cookiefile，SSL验证，为邮政数据和后续请求编码的url表单等几项内容应使用相同的cookie和代理数据

I am not sure it would help you but i am able to successfully query SSL site with the following code. There are several things like user agent, cookiefile, SSL verify, url form encoded for post data and subsequent request should use the same cookie and agent data

 $config['useragent'] = 'Mozilla/5.0 (Windows NT 6.2; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_USERAGENT, $config['useragent']);
curl_setopt($ch, CURLOPT_REFERER, 'http://google.com/');
$dir = dirname(__FILE__);
$config['cookie_file'] = $dir."/".md5($_SERVER['REMOTE_ADDR']) . '.txt';
curl_setopt($ch, CURLOPT_COOKIEFILE, $config['cookie_file']);
curl_setopt($ch, CURLOPT_COOKIEJAR, $config['cookie_file']);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_NOBODY, 0);    
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch,CURLOPT_HEADER,0);
$html=curl_exec($ch);

后续呼叫请求（请注意，它使用的是cookie，是在第一个请求中生成的useragent）

Subsequent call request(note it is using the cookie, useragent generated in first request)

$post = 'city_id=3&length-3';
$headers = array();
$headers[] = 'Accept: application/json, text/javascript, */*; q=0.01'; 
$headers[] = 'Accept-Language: en-US,en;q=0.5';
$headers[] = 'Content-Length:'.strlen($post);
$headers[] = 'Content-Type: application/x-www-form-urlencoded; charset=utf-8';
$headers[] = 'X-Requested-With: XMLHttpRequest';

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$link);
curl_setopt($ch, CURLOPT_USERAGENT, $config['useragent']);          
curl_setopt($ch, CURLOPT_COOKIEFILE, $config['cookie_file']);
curl_setopt($ch, CURLOPT_COOKIEJAR, $config['cookie_file']);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_NOBODY, 0);    
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch,CURLOPT_HEADER,0);
$linkhtml=curl_exec($ch);
