求帮忙看下，哪里有问题，另:上面这些参数用python是可以读出数据(json)来的

CURLOPT_HTTPHEADER：

一个用来设置HTTP头字段的数组。使用如下的形式的数组进行设置： array('Content-type: text/plain', 'Content-length: 100')    

<?php
function getwebcontent($url){
    $ch = curl_init();
    $data = array (
        'ap' => '2',
        'c1' => '4',
        'c2' => '4',
        'g_w' => '0100',
        'dd' => '0',
        'h' => '8',
        'iasign' => 'bedvkt2gyd9vkgrx',
        'pp' => '200',
    );
    $headers['X-rvt'] = 'IA401004bedvkt2gyd9vkgrx82lIsT';
    $headers['Referer'] = 'http://www.benmi.com/IA.html?c1=4&c2=4&g_w=0100&h=1';
    $headers['Accept-Language'] = 'zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3';
    $headers['Cookie'] = 'iasign=bedvkt2gyd9vkgrx;';
    $timeout = 20;
    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_POST, 1);
    curl_setopt ($ch, CURLOPT_VERBOSE , 0);
    curl_setopt ($ch, CURLOPT_HEADER, 1);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 0);
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0);
    curl_setopt ($ch, CURLOPT_POSTFIELDS, $data );
    curl_setopt ($ch, CURLOPT_HTTPHEADER , $headers);
    $contents = curl_exec($ch);
    curl_close($ch);
    return  $contents;
}
$c = getwebcontent('http://www.benmi.com/Ashx/IAPageAjax.ashx');
print($c);

追问

你有木在机子上跑一跑？这个是400错误，Invalid Header
帮忙研究下，我实在是懵了
