php实现post和get

file_get_contents版本:

01

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。
