Socket_php 팁을 사용하여 HTTP 요청을 보내는 PHP 방법

이 기사의 예에서는 PHP가 소켓을 사용하여 HTTP 요청을 보내는 방법을 설명합니다. 참고하실 수 있도록 모든 사람과 공유하세요. 자세한 내용은 다음과 같습니다.

소켓 모드:

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
//socket_set_option($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 메서드 :

$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);
}

원래 소켓 모드:

$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);
}

스트림 방법(get):

$http = <<<eof

$hdrs = array(

        'timeout'=>1, //超时 秒
        'method' => 'GET', //默认方式

    ),
);

$context = stream_context_create($hdrs);
echo file_get_contents('http://www.baidu.com', 0, $context);

스트리밍 방법 게시물:

$http = <<<eof

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);

참고: http1.1에는 Host 헤더가 포함되어야 하지만 http1.0에는 필요하지 않습니다.
