PHP使用socket发送HTTP请求的方法
本文实例讲述了PHP使用socket发送HTTP请求的方法。分享给大家供大家参考,具体如下:
socket方式:
$socket=socket_create(AF_INET,SOCK_STREAM,SOL_TCP); //socket_set_option($socket,SOL_SOCKET,SO_SNDTIMEO,array("sec"=>20,"usec"=>0)); socket_connect($socket,'www.baidu.com',80); //里面的换行代表\r\n注意拷贝的代码后面可能有空格 $http=<<<eof GET/HTTP/1.0 Accept:*/* User-Agent:Lowell-Agent Host:www.baidu.com Connection:Close eof; socket_write($socket,$http,strlen($http)); while($str=socket_read($socket,1024)) { echo$str; } socket_close($socket);
fsockopen方式:
$fp=fsockopen("www.baidu.com",80,$errno,$errstr,30); if(!$fp){ echo"$errstr($errno)<br/>\n"; }else{ $out="GET/HTTP/1.1\r\n"; $out.="Host:www.baidu.com\r\n"; $out.="Connection:Close\r\n\r\n"; fwrite($fp,$http); while(!feof($fp)){ echofgets($fp,128); } fclose($fp); }
原始socket方式:
$fp=stream_socket_client("tcp://www.baidu.com:80",$errno,$errstr,30); if(!$fp){ echo"$errstr($errno)<br/>\n"; }else{ $http=<<<eof GET/HTTP/1.0 Accept:*/* User-Agent:Lowell-Agent Host:www.baidu.com Connection:Close eof; fwrite($fp,$http); while(!feof($fp)){ echofgets($fp,1024); } fclose($fp); }
stream 方式(get):
$http=<<<eof Host:www.baidu.com User-Agent:Mozilla/5.0(WindowsNT6.1;WOW64;rv:27.0)Gecko/20100101Firefox/27.0 Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language:zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3 Cookie:BAIDUID=79D98B1AD8436C57B967E111E484F1CD:FG=1;BDUSS=lF-UFFOanFPVG92NmF4U3NiTEoxOFh4YVBCTnZaMUtoTUNhZmxrWThwN25IaUJVQVFBQUFBJCQAAAAAAAAAAAEAAADzo1gKc2lxaW5pYW8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAOeR-FPnkfhTU;BAIDUPSID=79D98B1AD8436C57B967E111E484F1CD;BD_UPN=13314352;BD_HOME=1;H_PS_PSSID=10047_1435_10874_10212_10501_10496_10753_10796_10219_10355_10666_10597_10095_10658_10442_10700_10460_10360_10618;sug=3;sugstore=0;ORIGIN=2;bdime=0 Connection:keep-alive Cache-Control:max-age=0 eof; $hdrs=array( 'http'=>array( 'header'=>$http, 'timeout'=>1,//超时秒 'method'=>'GET',//默认方式 'protocol_version'=>'1.1',//默认为1.0 ), ); //参数格式参考http://php.net/manual/zh/context.http.php //curl方式的格式可以参考;http://php.net/manual/zh/context.curl.php $context=stream_context_create($hdrs); echofile_get_contents('http://www.baidu.com',0,$context);
stream 方式post:
$postdata=http_build_query(array('act'=>'save','id'=>387171)); $http=<<<eof Host:www.baidu.com User-Agent:Mozilla/5.0(WindowsNT6.1;WOW64;rv:27.0)Gecko/20100101Firefox/27.0 Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language:zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3 Content-Type:application/x-www-form-urlencoded;charset=UTF-8 Cookie:BAIDUID=79D98B1AD8436C57B967E111E484F1CD:FG=1;BDUSS=lF-UFFOanFPVG92NmF4U3NiTEoxOFh4YVBCTnZaMUtoTUNhZmxrWThwN25IaUJVQVFBQUFBJCQAAAAAAAAAAAEAAADzo1gKc2lxaW5pYW8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAOeR-FPnkfhTU;BAIDUPSID=79D98B1AD8436C57B967E111E484F1CD;BD_UPN=13314352;BD_HOME=1;H_PS_PSSID=10047_1435_10874_10212_10501_10496_10753_10796_10219_10355_10666_10597_10095_10658_10442_10700_10460_10360_10618;sug=3;sugstore=0;ORIGIN=2;bdime=0 Connection:keep-alive Cache-Control:max-age=0 eof; #注意post方式需要增加Content-Type $hdrs=array( 'http'=>array( 'header'=>$http, 'timeout'=>1,//超时秒 'method'=>'POST', 'content'=>$postdata, 'protocol_version'=>'1.1',//默认为1.0 ), ); //参数格式参考http://php.net/manual/zh/context.http.php //curl方式的格式可以参考;http://php.net/manual/zh/context.curl.php $context=stream_context_create($hdrs); echofile_get_contents('http://test.cm/song.php',0,$context);
注意:http1.1中必须包含Host头,而http1.0中则可以没有
