PHP发送POST请求的三种方式 分别使用curl file_get_content fsocket 来实现post提交数据
class Request{
public static function post($url,$post_data = '',$timeout = 5){//curl
$ch = curl_init();
curl_setopt ($ch,CURLOPT_URL,$url);
curl_setopt ($ch,CURLOPT_POST,1);
if($post_data != ''){
curl_setopt($ch,CURLOPT_POSTFIELDS,$post_data);
}
curl_setopt ($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
curl_setopt($ch,CURLOPT_HEADER,false);
$file_contents = curl_exec($ch);
curl_close($ch);
return $file_contents;
}
public static function post2($url,$data){//file_get_content
$postdata = http_build_query(
$data
);
$opts = array('http' =>
array(
'method' => 'POST','header' => 'Content-type: application/x-www-form-urlencoded','content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents($url,false,$context);
return $result;
}
public static function post3($host,$path,$query,$others=''){//fsocket
$post="POST $path HTTP/1.1\\r\\nHost: $host\\r\\n";
$post.="Content-type: application/x-www-form-";
$post.="urlencoded\\r\\n${others}";
$post.="User-Agent: Mozilla 4.0\\r\\nContent-length: ";
$post.=strlen($query)."\\r\\nConnection: close\\r\\n\\r\\n$query";
$h=fsockopen($host,80);
fwrite($h,$post);
for($a=0,$r='';!$a;){
$b=fread($h,8192);
$r.=$b;
$a=(($b=='')?1:0);
}
fclose($h);
return $r;
}
}
