PHP implements post and get

file_get_contents版本：

01

<?php

02

/**

03	* Send post request

04	* @param string $url request address

05	* @param array $post_data post key-value pair data

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);

Practical experience:

When I used the above code to send an http request to another server, I found that if the server takes too long to process the request, the local PHP will interrupt the request, which is the so-called timeout interrupt. The first one I suspect that the execution time of PHP itself exceeds the limit, but I shouldn’t think about it because I have set the “PHP execution time limit” according to this article a long time ago ([Recommended] PHP upload file size limit list). After careful consideration, I thought I thought it should be a time limit on the http request itself, so I thought of how to increase the time limit on the http request. . . . . . Check the PHP manual, and there is indeed a parameter "timeout", I don't know how big it is by default. When you set its value to a larger value, the problem will be solved. Let me make a note~~~

Socket version:

01

/**

02	* Socket version

03	* How to use:

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, 12

$socket

"User-Agent: Socket Example");

et, );

"HOST: $remote_server"

13

fwrite(

$sock et, ); $post_string) + 8) .

"Content-type: application/x-www-form-urlencoded"

$socket, "Content-length: ". (strlen(

""

);16

15 "Accept:*/*");

)

fwrite($socket ""17

,

);

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

18

,

"");$header=

19

""

;

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;

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