这篇文章主要介绍了php自定义类fsocket模拟post或get请求的方法,涉及php使用socket模拟post及get请求的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了php自定义类fsocket模拟post或get请求的方法，分享给大家供大家参考，具体如下：

zsocket.class.php文件如下：

1. <?php
2. class ZSocket {
3. /*
4. * Init
5. */
6. private function _fsockopen($host, $port, &$errno, &$errstr, $timeout){
7. $ip = @gethostbyname($host);
8. $s = @socket_create(AF_INET, SOCK_STREAM, 0);
9. if(socket_set_nonblock($s)){
10. $r = @socket_connect($s, $ip, $port);
11. if ($r || socket_last_error() == EINPROGRESS) {
12. $errno = EINPROGRESS;
13. return $s;
14. }
15. }
16. $errno = socket_last_error($s);
17. $errstr = socket_strerror($errno);
18. socket_close($s);
19. return false;
20. }
21. /*
22. * 设置Cookie
23. */
24. private function _setCookie($cookie){
25. $_cookies = explode("; ",$cookie);
26. $_tmp = explode("=",$_cookies[0]);
27. setcookie($_tmp[0], $_tmp[1]);
28. return $_cookies;
29. }
30. /*
31. * 获取返回数据header内容
32. */
33. private function _getDataHeader(&$fp,&$reHeader,&$cookies){
34. $maxlen = 0;
35. while(!feof($fp)){
36. $line = fgets($fp,1024);
37. if(substr($line, 0, 12) == 'Set-Cookie: '){ $cookies[] = $this->_setCookie(substr($line, 12)); }
38. $reHeader .= $line;
39. if(substr($line, 0, 16) == 'Content-Length: '){
40. $maxlen = intval(substr($line, 16, -2));
41. }
42. if($line == "\r\n" || $line == "") break;
43. }
44. return $maxlen;
45. }
46. /*
47. * 获取返回数据正文内容
48. */
49. private function _getDataBody(&$fp,$maxlen){
50. $reData = "";
51. while(!feof($fp)){
52. $line = fgets($fp,$maxlen+1);
53. $reData .= $line;
54. if(strlen($line) < $maxlen) $maxlen = $maxlen - strlen($line);
55. else break;
56. }
57. return $reData;
58. }
59. /*
60. * 设置并返回要发送的header内容
61. */
62. public function get_HeaderInfo($host,$type='GET',$file='/',$params=array(),$head=array(),$cookies=array()){
63. $_params = $_cookies = '';
64. if(is_array($params)){
65. foreach($params as $key=>$value){
66. $_params .= "&".$key."=".urlencode($value);
67. }
68. $_params = (strlen($_params) > 1) ? substr($_params,1) : '';
69. }else if(is_string($params)){
70. $_params = urlencode($params);
71. }
72. foreach($cookies as $key=>$value){
73. $_cookies .= "; ".$key."=".urlencode($value);
74. }
75. $_cookies = (strlen($_cookies) > 2) ? substr($_cookies,2) : '';
76. $file .= ($type == 'GET') ? ($_params == '' ? '' : '?'.$_params) : '';
77. $header = $type." ".$file." HTTP/1.1\r\n";
78. $header .= "Host: ".$host."\r\n";
79. //$header .= "Referer: ".get_ip()."\r\n";
80. //$header .= "X-Forwarded-For: ".get_ip()."\r\n";
81. $header .= ($type == 'GET') ? '' : "Content-Type: application/x-www-form-urlencoded\r\n";
82. if(is_array($head) && $head != array()){
83. foreach($head as $k=>$v){
84. $header .= $k.": ".$v."\r\n";
85. }
86. }
87. $header .= "Content-Length: ".strlen($_params)."\r\n";
88. if($_cookies != '') $header .= "Cookie: ".$_cookies."\r\n";
89. /*
90. foreach($_SERVER as $name => $value){
91. if(substr($name, 0, 5) == 'HTTP_' && $name != 'HTTP_HOST'){
92. $header .= str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5))))).":".$value."\r\n";
93. }
94. }
95. */
96. $header .= "Connection: Close\r\n\r\n";
97. $header .= $_params."\r\n";
98. return $header;
99. }
100. /*
101. * 发送,并返回结果 Array
102. */
103. public function get_SendData($host,$port=80,$header=''){
104. if(function_exists('fsockopen')){
105. $fp = fsockopen($host,$port,$errno,$errstr,10);
106. }else if(function_exists('pfsockopen')){
107. $fp = pfsockopen($host,$port,$errno,$errstr,10);
108. }else if(function_exists('stream_socket_client')){
109. $fp = stream_socket_client($host.':'.$port,$errno,$errstr,10);
110. }else{
111. $fp = $this->_fsockopen($host,$port,$errno,$errstr,10);
112. }
113. $fp = fsockopen($host,$port,$errno,$errstr,10);
114. if(!$fp) return array('header'=>'','data'=>$errstr."--->".$errno,'cookie'=>'');
115. $reHeader = $reData = "";
116. $cookies = array();
117. fputs($fp,$header);
118. $maxlen = $this->_getDataHeader($fp,$reHeader,$cookies);
119. $reData = $this->_getDataBody($fp,$maxlen);
120. fclose($fp);
121. return array('header'=>$reHeader,'data'=>$reData,'cookie'=>$cookies);
122. }
123. }

demo代码如下：

1. $host = 'www.phpfensi.com';
2. $port = '80';
3. $type = 'POST';
4. $file = '/';
5. $params = '';
6. //include_once('include/zsocket.class.php'); //include
7. $zsk = new ZSocket();
8. $header = $zsk->get_HeaderInfo($host,$type,$file,$params);
9. $data = $zsk->get_SendData($host,$port,$header);
10. /*
11. echo "<!--\r\n";
12. print_r($header);
13. print_r($data);
14. echo "-->\r\n";
15. */
16. var_dump($header);
17. var_dump($data);
