php发送post请求(转)
在使用采集的时候 需要发送post请求。有3种方法。
第一种方法:file_get_contents();
function request_by_other($remote_server,$post_string){
$context = array(
'http'=>array(
‘method’=>’POST’,
‘header’=>’Content-type: application/x-www-form-urlencoded’.”\r\n”.
‘User-Agent : Jimmy\’s POST Example beta’.”\r\n”.
‘Content-length: ‘.strlen($post_string)+8,
‘content’=>’mypost=’.$post_string)
);
$stream_context = stream_context_create($context);
$data = file_get_contents($remote_server,FALSE,$stream_context);
return $data;
}
直接调用函数即可
$post_string = "app=request&version=beta";
request_by_other('http://weiyeying.cn/index.php',$post_string);
第二种方法curl();
curl看你php环境支不支持 如果不支持会报错。需要开启curl扩展即可。
function request_by_curl($remote_server,$post_string){
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$remote_server);
curl_setopt($ch,CURLOPT_POSTFIELDS,'mypost='.$post_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_USERAGENT,"Jimmy's CURL Example beta");
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$post_string = "app=request&version=beta";
request_by_curl('http://weiyeying.cn/index.php',$post_string);
第三张方法:Socket()
function request_by_socket($remote_server,$remote_path,$post_string,$port = 80,$timeout = 30){
$socket = fsockopen($remote_server,$port,$errno,$errstr,$timeout);
if (!$socket) die("$errstr($errno)");
fwrite($socket,"POST $remote_path HTTP/1.0\r\n");
fwrite($socket,"User-Agent: Socket Example\r\n");
fwrite($socket,"HOST: $remote_server\r\n");
fwrite($socket,"Content-type: application/x-www-form-urlencoded\r\n");
fwrite($socket,"Content-length: ".strlen($post_string)+8."\r\n");
fwrite($socket,"Accept:*/*\r\n");
fwrite($socket,"\r\n");
fwrite($socket,"mypost=$post_string\r\n");
fwrite($socket,"\r\n");
$header = "";
while ($str = trim(fgets($socket,4096))) {
$header.=$str;
}
$data = "";
while (!feof($socket)) {
$data .= fgets($socket,4096);
}
return $data;
}
执行函数即可
$post_string = "app=socket&version=beta";
request_by_socket('weiyeying.cn','/restServer.php',$post_string);
