求大神给个php示例代码模拟登录http://www.19lou.com/login

逐步分析 就行

人家做了防跨站访问的话就不能实现了

不知道php的curl会不会在302重定向的时候，丢失cookie, 刚刚看了看，在login之后是302重定向了

在python的urllib2遇到302时候，默认设置会丢失cookie,所以个人感觉如果你提交的参数没有问题的话，　可能是这个原因。

你想要的curl，bash版本：

curl 'https://www.19lou.com/login' -H 'Pragma: no-cache' -H 'Origin: http://www.19lou.com' -H 'Accept-Encoding: gzip, deflate' -H 'Accept-Language: zh-CN,zh;q=0.8,ja;q=0.6,en;q=0.4' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.116 Safari/537.36' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H 'Cache-Control: no-cache' -H 'Referer: http://www.19lou.com/login' -H 'Cookie: JSESSIONID=1F755C103A98DD613F80F3AFB99B3EC9; sys=67174666.20480.0000; _DM_SID_=b13ac27ac3d29a85ad6094b375981b8f; _DM_S_=487781a528838b00e091f3d500a33239' -H 'Connection: keep-alive' -H 'DNT: 1' --data 'refererUrl=aHR0cDovL3d3dy4xOWxvdS5jb20%3D&checked=0&userName=wangtets123&userPass=%231234567890&captcha=&remember=1&ssl=true' --compressed

善用chrome的F12，很强大的。

谢谢大家。已经解决
代码如下

<?php
function login_post($url, $cookie, $post) { 
    $curl = curl_init();//初始化curl模块 
    curl_setopt($curl, CURLOPT_URL, $url);//登录提交的地址 
    curl_setopt($curl, CURLOPT_HEADER, 0);//是否显示头信息 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 0);//是否自动显示返回的信息 
    curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie); //设置Cookie信息保存在指定的文件中 
    curl_setopt($curl, CURLOPT_POST, 1);//post方式提交 
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post));//要提交的信息 
    curl_exec($curl);//执行cURL 
    curl_close($curl);//关闭cURL资源，并且释放系统资源 
} 
function get_content($url1, $cookie) { 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $url1); 
    curl_setopt($ch, CURLOPT_HEADER, 0); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie); //读取cookie 
    $rs = curl_exec($ch); //执行cURL抓取页面内容 
    curl_close($ch); 
    return $rs; 
} 

$post = array ( 
   'refererUrl'=>'aHR0cDovL3d3dy4xOWxvdS5jb20v',
   'checked'=>'0',
   'userName'=>$user,
   'userPass'=>$pass,
    'captcha'=>'',
    'remember'=>'1',
    'ssl'=>'true', 
); 
$url = "https://www.19lou.com/login";
$cookie = dirname(__FILE__) . '/sss.txt'; 
//登录后要获取信息的地址 
$url1 = "http://www.19lou.com/wap/myinfo/index"; 
//模拟登录 
login_post($url, $cookie, $post); 
//获取登录页的信息 
echo $content = get_content($url1, $cookie);

简单测试了一下，没有特殊的校验啊，传这些参数就好了，refererUrl这个参数可以从

这个链接的r=处找到

================分割线======================
贴代码吧

function curl_post_contents($url, $params, $cookie_file, $has_cookie, $use_http_build_query = false, $headers = array(), $time_out = 30)
{
    if ($use_http_build_query) {
        $params = http_build_query($params);
    }

    $curlHandle = curl_init();
    if ($headers) {
        curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);
    }
    curl_setopt($curlHandle, CURLOPT_POST, 1);
    curl_setopt($curlHandle, CURLOPT_URL, $url);
    curl_setopt($curlHandle, CURLOPT_SSL_VERIFYPEER, 0); //让CURL支持HTTPS访问
    curl_setopt($curlHandle, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curlHandle, CURLOPT_CONNECTTIMEOUT, $time_out);
    curl_setopt($curlHandle, CURLOPT_TIMEOUT, $time_out);
    curl_setopt($curlHandle, CURLOPT_POSTFIELDS, $params);
    curl_setopt($curlHandle, CURLOPT_FOLLOWLOCATION, 1);//跳转到重定向的地址
    if ($has_cookie)
        curl_setopt($curlHandle, CURLOPT_COOKIEFILE, $cookie_file);
    else
        curl_setopt($curlHandle, CURLOPT_COOKIEJAR, $cookie_file);
    $result = curl_exec($curlHandle);

    curl_close($curlHandle);
    return $result;
}



$data = array(
    'refererUrl'=>'aHR0cDovL3d3dy4xOWxvdS5jb20=',
    'checked' => 0,
    'userName' => 'wangtets123',
    'userPass' => '#1234567890',
    'ssl' => true
);
$url = 'https://www.19lou.com/login';
$cookie_file = dirname(__FILE__)."/pic.cookie";
$result = curl_post_contents($url,$data,$cookie_file,false,true);
echo $result;

cookie放在pic.cookie里面，接下来要做什么把这个cookie放进去就好了
