這篇文章主要介紹了php發送post請求的三種方法,分別使用curl、file_get_content、fsocket來實現post提交數據,需要的朋友可以參考下

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;

??? }
}
