file_get_contents版本:

01 <?php

02 /**

03  * 发送post请求

04  * @param string $url 请求地址

05  * @param array $post_data post键值对数据

06  * @return string

07  */

08 functionsend_post($url, $post_data) {

09  

10     $postdata= http_build_query($post_data);

11     $options= array(

12         'http'=> array(

13             'method'=> 'POST',

14             'header'=> 'Content-type:application/x-www-form-urlencoded',

15             'content'=> $postdata,

16             'timeout'=> 15 * 60 // 超时时间(单位:s)

17         )

18     );

19     $context= stream_context_create($options);

20     $result= file_get_contents($url, false, $context);

21  

22     return$result;

23 }

使用如下:

1 $post_data= array(

2     'username'=> 'stclair2201',

3     'password'=> 'handan'

4 );

5 send_post('http://blog.snsgou.com', $post_data);

实战经验:

当我利用上述代码给另一台服务器发送http请求时,发现,如果服务器处理请求时间过长,本地的PHP会中断请求,即所谓的超时中断,第一个怀疑的是PHP本身执行时间的超过限制,但想想也不应该,因为老早就按照这篇文章设置了“PHP执行时间限制”(【推荐】PHP上传文件大小限制大全 ),仔细琢磨,想想,应该是http请求本身的一个时间限制,于是乎,就想到了怎么给http请求时间限制搞大一点。。。。。。查看PHP手册,果真有个参数 “ timeout ”,默认不知道多大,当把它的值设大一点,问题得已解决,弱弱地做个笔记~~~

Socket版本:

01 /**

02  * Socket版本

03  * 使用方法:

04  * $post_string = "app=socket&version=beta";

05  * request_by_socket('blog.snsgou.com', '/restServer.php', $post_string);

06  */

07 functionrequest_by_socket($remote_server,$remote_path,$post_string,$port= 80,$timeout= 30) {

08     $socket= fsockopen($remote_server, $port, $errno, $errstr, $timeout);

09     if(!$socket) die("$errstr($errno)");

10     fwrite($socket, "POST $remote_path HTTP/1.0");

11     fwrite($socket, "User-Agent: Socket Example");

12     fwrite($socket, "HOST: $remote_server");

13     fwrite($socket, "Content-type: application/x-www-form-urlencoded");

14     fwrite($socket, "Content-length: ". (strlen($post_string) + 8) . "");

15     fwrite($socket, "Accept:*/*");

16     fwrite($socket, "");

17     fwrite($socket, "mypost=$post_string");

18     fwrite($socket, "");

19     $header= "";

20     while($str= trim(fgets($socket, 4096))) {

21         $header.= $str;

22     }

23  

24     $data= "";

25     while(!feof($socket)) {

26         $data.= fgets($socket, 4096);

27     }

28  

29     return$data;

30 }

Curl版本:

01 /**

02  * Curl版本

03  * 使用方法:

04  * $post_string = "app=request&version=beta";

05  * request_by_curl('http://blog.snsgou.com/restServer.php', $post_string);

06  */

07 functionrequest_by_curl($remote_server, $post_string) {

08     $ch= curl_init();

09     curl_setopt($ch, CURLOPT_URL, $remote_server);

10     curl_setopt($ch, CURLOPT_POSTFIELDS, 'mypost='. $post_string);

11     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

12     curl_setopt($ch, CURLOPT_USERAGENT, "snsgou.com's CURL Example beta");

13     $data= curl_exec($ch);

14     curl_close($ch);

15  

16     return$data;

17 }

Curl版本(2)

01 /**

02  * 发送HTTP请求

03  *

04  * @param string $url 请求地址

05  * @param string $method 请求方式 GET/POST

06  * @param string $refererUrl 请求来源地址

07  * @param array $data 发送数据

08  * @param string $contentType

09  * @param string $timeout

10  * @param string $proxy

11  * @return boolean

12  */

13 functionsend_request($url, $data, $refererUrl= '', $method= 'GET', $contentType= 'application/json', $timeout= 30, $proxy= false) {

14     $ch= null;

15     if('POST'=== strtoupper($method)) {

16         $ch= curl_init($url);

17         curl_setopt($ch, CURLOPT_POST, 1);

18         curl_setopt($ch, CURLOPT_HEADER,0 );

19         curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1);

20         curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

21         curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);

22         curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);

23         if($refererUrl) {

24             curl_setopt($ch, CURLOPT_REFERER, $refererUrl);

25         }

26         if($contentType) {

27             curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:'.$contentType));

28         }

29         if(is_string($data)){

30             curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

31         } else{

32             curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

33         }

34     } elseif('GET'=== strtoupper($method)) {

35         if(is_string($data)) {

36             $real_url= $url. (strpos($url, '?') === false ? '?': ''). $data;

37         } else{

38             $real_url= $url. (strpos($url, '?') === false ? '?': ''). http_build_query($data);

39         }

40  

41         $ch= curl_init($real_url);

42         curl_setopt($ch, CURLOPT_HEADER, 0);

43         curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:'.$contentType));

44         curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

45         curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);

46         if($refererUrl) {

47             curl_setopt($ch, CURLOPT_REFERER, $refererUrl);

48         }

49     } else{

50         $args= func_get_args();

51         returnfalse;

52     }

53  

54     if($proxy) {

55         curl_setopt($ch, CURLOPT_PROXY, $proxy);

56     }

57     $ret= curl_exec($ch);

58     $info= curl_getinfo($ch);

59     $contents= array(

60             'httpInfo'=> array(

61                     'send'=> $data,

62                     'url'=> $url,

63                     'ret'=> $ret,

64                     'http'=> $info,

65             )

66     );

67  

68     curl_close($ch);

69     return$ret;

70 }

调用 WCF接口 的一个例子:$json = restRequest($r_url,'POST', json_encode($data));

以上就介绍了php实现post和get,包括了方面的内容,希望对PHP教程有兴趣的朋友有所帮助。
