php curl模拟登陆 模拟发帖 菜鸟求救

[wonderwiller]

需要模拟登陆发帖的网站:
http://bbs.miaozhan360.com/forum.php
账号密码都是 wonderwiller

我的代码:
<?php
//$discuz_url = 'http://127.0.0.1/discuz/';//论坛地址
//$login_url = $discuz_url .'logging.php?action=login';//登录页地址

$login_url='http://bbs.miaozhan360.com/member.php?mod=logging&action=login&loginsubmit=yes&infloat=yes&lssubmit=yes';

$post_fields = array();
//以下两项不需要修改
$post_fields['loginfield'] = 'username';
$post_fields['loginsubmit'] = 'true';
//用户名和密码，必须填写
$post_fields['username'] = 'wonderwiller';
$post_fields['password'] = 'wonderwiller';
//安全提问
$post_fields['questionid'] = 0;
$post_fields['answer'] = '';
//@todo验证码
$post_fields['seccodeverify'] = '';

//获取表单FORMHASH
$ch = curl_init($login_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$contents = curl_exec($ch);
curl_close($ch);



preg_match('/<input\s*type="hidden"\s*name="formhash"\s*value="(.*?)"\s*\/>/i', $contents, $matches);
if(!empty($matches)) {
$formhash = $matches[1];
} else {
die('Not found the forumhash.');
}



//POST数据，获取COOKIE,cookie文件放在网站的temp目录下
$cookie_file = tempnam('./temp','cookie');

$ch = curl_init($login_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
$co=curl_exec($ch);
curl_close($ch);

echo $co;

//取到了关键的cookie文件就可以带着cookie文件去模拟发帖,fid为论坛的栏目ID
//$send_url = $discuz_url."post.php?action=newthread&fid=2";
$send_url='http://bbs.miaozhan360.com/forum.php?mod=post&action=newthread&fid=53';


$ch = curl_init($send_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
$contents = curl_exec($ch);
curl_close($ch);

//这里的hash码和登陆窗口的hash码的正则不太一样，这里的hidden多了一个id属性
preg_match('/<input\s*type="hidden"\s*name="formhash"\s*id="formhash"\s*value="(.*?)"\s*\/>/i', $contents, $matches);
if(!empty($matches)) {
$formhash = $matches[1];
} else {
die('Not found the forumhash.');
}


$post_data = array();
//帖子标题
$post_data['subject'] = 'test2';
//帖子内容
$post_data['message'] = 'test2';
$post_data['topicsubmit'] = "yes";
$post_data['extra'] = '';
//帖子标签
$post_data['tags'] = 'test';
//帖子的hash码，这个非常关键！假如缺少这个hash码，discuz会警告你来路的页面不正确
$post_data['formhash']=$formhash;


$ch = curl_init($send_url);
curl_setopt($ch, CURLOPT_REFERER, $send_url); //伪装REFERER
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
$mycontents = curl_exec($ch);
curl_close($ch);
echo $mycontents;
//清理cookie文件
unlink($cookie_file);

?>

遇到的问题很多啊

问题1：真实手工登陆时候输入账号密码后 会出现输入验证码的页面 可是模拟登陆时候 却迟迟不显示验证码页面 这是为何？如何修改代码呢？如何顺利登陆成功呢？

这是目前困扰菜鸟我的一大难题 诸位兄弟情发表见解
谢谢

简单看了下，估计是js判断的，你直接看JS代码，先获得验证码，再一起提交。而不是提交获得验证码。

获取验证码，返回的是图片,header 注意改下如

<?php 
header('Content-Type:image/png');
showAuthcode('验证码图片地址');
function showAuthcode( $authcode_url )
{
    
    $ch = curl_init($authcode_url);
    curl_setopt($ch, CURLOPT_REFERER, "来源页写下，有些程序会判断来源页");
    curl_exec($ch);
    curl_close($ch);
}
?>
