fsockopen读取、发送cookie及注意事项 -代码示例

function httpPost($url, $data,$cookieStr='')
{
$url_array = parse_url($url);
$host = $url_array['host'];
$port = isset($url_array['port'])?($url_array['port']):80;

if(!($conn = fsockopen($host,$port,$errno, $errstr, 30)))
{
return false;
}

$header = "POST ".$url." HTTP/1.1\r\n";
$header.= "Host : {$host}\r\n";
$header.= "Content-type: application/x-www-form-urlencoded\r\n";
$header.= "Content-Length:".strlen($data)."\r\n";
$header.= "Connection: close\r\n";
//这里是用来写cookie的
if (!empty($cookieStr)) {
$header.="Cookie: ".$cookieStr."\r\n";
}
//注意下面开头还加了个换行，结尾是两个换行
$header.= "\r\n{$data}\r\n\r\n";

//写数据
fwrite($conn,$header);

//这里读cookie
$cookieStr=array();
//下面的判断，读到空行时，说明头已经结束了，接下来是内容。
while( ($line=trim(fgets($conn))) != "" )
{
$header.=$line; /*   */
if(strstr($line,"Set-Cookie:"))
{
list($coo,$cookieLine)=explode(" ",$line);
$cookieStr[] = $cookieLine;
}
}
//if($len <= 0)
//{
//    return false;
// }
//读数据
//$body=fread($conn,$len);
while (!feof($conn)) {
$body .= fread($conn, 8192);
}

fclose($conn);

$result['body'] = $body;
$result['cookieArr'] = $cookieStr;

return $result;
