php发送get、post请求的6种方法简明总结
方法1:用file_get_contents以get方式获取内容：
<?php $url='https://www.nhooo.com/'; $html=file_get_contents($url); echo$html; ?>
方法2:用fopen打开url,以get方式获取内容：
<?php
$fp=fopen($url,‘r');
stream_get_meta_data($fp);
while(!feof($fp)){
$result.=fgets($fp,1024);
}
echo“urlbody:$result”;
fclose($fp);
?>
方法3：用file_get_contents函数,以post方式获取url
<?php $data=array(‘foo'=>‘bar'); $data=http_build_query($data); $opts=array( ‘http'=>array( ‘method'=>‘POST', ‘header'=>“Content-type:application/x-www-form-urlencodedrn”. “Content-Length:”.strlen($data).“rn”, ‘content'=>$data ) ); $context=stream_context_create($opts); $html=file_get_contents(‘http://localhost/e/admin/test.html',false,$context); echo$html; ?>
方法4：用fsockopen函数打开url，以get方式获取完整的数据，包括header和body,fsockopen需要PHP.ini中allow_url_fopen选项开启
<?php
functionget_url($url,$cookie=false)
{
$url=parse_url($url);
$query=$url[path].”?”.$url[query];
echo“Query:”.$query;
$fp=fsockopen($url[host],$url[port]?$url[port]:80,$errno,$errstr,30);
if(!$fp){
returnfalse;
}else{
$request=“GET$queryHTTP/1.1rn”;
$request.=“Host:$url[host]rn”;
$request.=“Connection:Closern”;
if($cookie)$request.=”Cookie:$cookien”;
$request.=”rn”;
fwrite($fp,$request);
while(!@feof($fp)){
$result.=@fgets($fp,1024);
}
fclose($fp);
return$result;
}
}
//获取url的html部分，去掉header
functionGetUrlHTML($url,$cookie=false)
{
$rowdata=get_url($url,$cookie);
if($rowdata)
{
$body=stristr($rowdata,”rnrn”);
$body=substr($body,4,strlen($body));
return$body;
}
returnfalse;
}
?>
方法5：用fsockopen函数打开url，以POST方式获取完整的数据，包括header和body
<?php
functionHTTP_Post($URL,$data,$cookie,$referrer=”")
{
//parsingthegivenURL
$URL_Info=parse_url($URL);
//Buildingreferrer
if($referrer==”")//ifnotgivenusethisscriptasreferrer
$referrer=”111″;
//makingstringfrom$data
foreach($dataas$key=>$value)
$values[]=”$key=”.urlencode($value);
$data_string=implode(“&”,$values);
//Findoutwhichportisneeded–ifnotgivenusestandard(=80)
if(!isset($URL_Info["port"]))
$URL_Info["port"]=80;
//buildingPOST-request:
$request.=”POST“.$URL_Info["path"].”HTTP/1.1n”;
$request.=”Host:“.$URL_Info["host"].”n”;
$request.=”Referer:$referern”;
$request.=”Content-type:application/x-www-form-urlencodedn”;
$request.=”Content-length:“.strlen($data_string).”n”;
$request.=”Connection:closen”;
$request.=”Cookie:$cookien”;
$request.=”n”;
$request.=$data_string.”n”;
$fp=fsockopen($URL_Info["host"],$URL_Info["port"]);
fputs($fp,$request);
while(!feof($fp)){
$result.=fgets($fp,1024);
}
fclose($fp);
return$result;
}
?>
方法6:使用curl库，使用curl库之前，可能需要查看一下php.ini是否已经打开了curl扩展
<?php $ch=curl_init(); $timeout=5; curl_setopt($ch,CURLOPT_URL,‘https://www.nhooo.com/'); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout); $file_contents=curl_exec($ch); curl_close($ch); echo$file_contents; ?>
