php使用fsockopen函数发送post,get请求获取网页内容的方法
本文实例讲述了php使用fsockopen函数发送post,get请求获取网页内容的方法。分享给大家供大家参考。
具体实现代码如下:
复制代码 代码如下:$post =1;
$url = parse_url($url);
$host ='https://www.jb51.net';
$path ='/';
$query ='"post $path http/1.0 ";
$out .= "accept: */* ";
//$out .= "referer: $boardurl ";
$out .= "accept-language: zh-cn ";
$out .= "content-type: application/x-www-form-urlencoded ";
$out .= "user-agent: $_server[http_user_agent] ";
$out .= "host: $host ";
$out .= 'content-length: '.strlen($post)." ";
$out .= "connection: close ";
$out .= "cache-control: no-cache ";
$out .= "cookie: $cookie ";
$out .= $post;
} else {
$out = "get $path http/1.0 ";
$out .= "accept: */* ";
//$out .= "referer: $boardurl ";
$out .= "accept-language: zh-cn ";
$out .= "user-agent: $_server[http_user_agent] ";
$out .= "host: $host ";
$out .= "connection: close ";
$out .= "cookie: $cookie ";
}
$fp = @fsockopen(($ip "codetitle">复制代码 代码如下:resource fsockopen(string $hostname [,int $port = -1 [, int &$errno [,string &$errstr [, float $timeout = ini_get("default_socket_timeout") ]]]] )
启动一个套接字连接到指定的主机的资源,php支持在互联网领域的目标和unix在所支持的套接字传输列表说明,所支持的传输列表也可以检索使用stream_get_transports().
该插座预设会被启用,阻塞模式,你可以切换到非阻塞模式使用stream_set_blocking(),如果上面实例看不懂,就来看个简的吧,代码如下:
复制代码 代码如下:$fp = fsockopen("www.jb51.net", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno) ";
} else {
$out = "get / http/1.1 ";
$out .= "host: www.jb51.net";
$out .= "connection: close ";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
希望本文所述对大家的PHP程序设计有所帮助。
