下面是一个贴吧回复的http post
<?php
$url = 'http://tieba.baidu.com/f/commit/post/add';
$cookie = '';
$postdata = array(
'ie=utf-8',
'kw=%E5%B0%8F%E5%86%B0hi',
'fid=14747058',
'tid=3265164327',
'floor_num=8',
'quote_id=56930253344',
'rich_text=1',
'tbs=f214b6d648c8cc5c1409296432',
'content=gg2',
'lp_type=0',
'lp_sub_type=0',
'new_vcode=1',
'tag=rr',
'repostid=56930253344',
'anonymous=0',
'vcode=',
'vcode_md5='
);
$postdata=implode("&",$postdata);
$header = array('Content-Type: application/x-www-form-urlencoded');
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
if ($postdata!='') curl_setopt($ch,CURLOPT_POSTFIELDS,$postdata);
if ($cookie!='') curl_setopt($ch,CURLOPT_COOKIE,$cookie);
if ($header!='') curl_setopt($ch,CURLOPT_HTTPHEADER,$header);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);//是否显示头信息
curl_setopt($ch,CURLOPT_HEADER,0); //是否输出页面内容
curl_setopt($ch,CURLOPT_TIMEOUT,20);//curl允许执行的最大时间
$re = curl_exec($ch);
curl_close($ch);
if($re[20] == 0)
{
echo "success";
}
else
{
echo "false";
}
?>
