file_get_contents版本：

01

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*/

08functionsend_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);

5send_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 */

07functionrequest_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;

30}

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