[PHP]代码

1. class Request{
3. public static function post($url, $post_data = '', $timeout = 5){//curl
5. $ch = curl_init();
7. curl_setopt ($ch, CURLOPT_URL, $url);
9. curl_setopt ($ch, CURLOPT_POST, 1);
11. if($post_data != ''){
13. curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
15. }
17. curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
19. curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
21. curl_setopt($ch, CURLOPT_HEADER, false);
23. $file_contents = curl_exec($ch);
25. curl_close($ch);
27. return $file_contents;
29. }
32. public static function post2($url, $data){//file_get_content
36. $postdata = http_build_query(
38. $data
40. );
44. $opts = array('http' =>
46. array(
48. 'method' => 'POST',
50. 'header' => 'Content-type: application/x-www-form-urlencoded',
52. 'content' => $postdata
54. )
56. );
60. $context = stream_context_create($opts);
63. $result = file_get_contents($url, false, $context);
65. return $result;
68. }
71. public static function post3($host,$path,$query,$others=''){//fsocket
74. $post="POST $path HTTP/1.1\r\nHost: $host\r\n";
76. $post.="Content-type: application/x-www-form-";
78. $post.="urlencoded\r\n${others}";
80. $post.="User-Agent: Mozilla 4.0\r\nContent-length: ";
82. $post.=strlen($query)."\r\nConnection: close\r\n\r\n$query";
84. $h=fsockopen($host,80);
86. fwrite($h,$post);
88. for($a=0,$r='';!$a;){
90. $b=fread($h,8192);
92. $r.=$b;
94. $a=(($b=='')?1:0);
96. }
98. fclose($h);
100. return $r;
102. }
