标签: javascript php ajax curl

当我发送带有CURL的Ajax请求时,我收到400 http_code错误是我的代码。

    $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);

//在发出Curl请求后我得到了以下回复

我不确定它会对您有所帮助,但我能够使用以下代码成功查询SSL站点。 有一些事情,如用户代理,cookiefile,SSL验证,为发布数据编码的url表单,后续请求应使用相同的cookie和代理数据

 $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);

后续的呼叫请求(注意它是使用cookie,在第一次请求中生成的useragent)

$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);
