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)) {
    echo fgets($fp, 128);
  }
  fclose($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)) {
    echo fgets($fp, 1024);
  }
  fclose($fp);
}

stream  方式（get）：

$http = <<<eof
host: www.baidu.com
user-agent: mozilla/5.0 (windows nt 6.1; wow64; rv:27.0) gecko/20100101 firefox/27.0

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);
echo file_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 (windows nt 6.1; wow64; rv:27.0) gecko/20100101 firefox/27.0

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);
echo file_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
