本文实例讲述了PHP模拟http请求的方法。分享给大家供大家参考,具体如下:
方法一:利用php的socket编程来直接给接口发送数据来模拟post的操作。
建立两个文件post.php,getpost.php
post.php内容如下:
1
2
3
4
5
6
7
8
9
10
11
12
13
14

24
25
26
27

<?php $flag = 0; $params = '' ; $errno = '' ; $errstr = '' ; //要post的数据 $argv = array ( 'var1' => 'abc' , 'var2' => 'how are you , my friend??' ); //构造要post的字符串 foreach ( $argv as $key => $value ) { if ( $flag !=0) { $params .= "&" ; $flag = 1; } $params .= $key . "=" ; $params .= urlencode( $value ); $flag = 1; } $length = strlen ( $params ); //创建socket连接 $fp = fsockopen ( "localhost" ,81, $errno , $errstr ,10) or exit ( $errstr . "--->" . $errno ); //构造post请求的头 $header = "POST /flandy/getpost.php HTTP/1.1\r\n" ; $header .= "Host:127.0.0.1\r\n" ; $header .= "Referer:/flandy/post.php\r\n" ; $header .= "Content-Type: application/x-www-form-urlencoded\r\n" ; $header .= "Content-Length: " . $length . "\r\n" ; $header .= "Connection: Close\r\n\r\n" ; //添加post的字符串 $header .= $params . "\r\n" ; //发送post的数据 fputs ( $fp , $header ); $inheader = 1; while (! feof ( $fp )) { $line = fgets ( $fp ,1024); //去除请求包的头只显示页面的返回数据 if ( $inheader && ( $line == "\n" || $line == "\r\n" )) { $inheader = 0; } if ( $inheader == 0) { echo $line ; } } fclose( $fp ); ?> |
getpost.php的内容如下:
1
2
3
4
5
6
|
<?php echo "this is the data posted" ; echo "<pre>" ; print_r( $_REQUEST ); echo "</pre>" ; ?> |
结果输出:
1
2
3
4
5
6
|
this is the data posted Array ( [var1] => abc [var2] => how are you , my friend?? ) |
以上代码在本机81端口下已经通过测试。
方法二:使用PHP的curl扩展或HttpClient.class.php类,这两个非常类似,下面简单的列出curl的实现代码。
两个文件post2.php和getpost2.php
post2.php的内容如下:
1
2
3
4
5
6
7
8
9
10
11
12
13

<?php $psecode = 'NDE005' ; $website = 'www.baidu.com' ; $amt = 1; $pwd = 123456; $ch = curl_init(); $curl_url = "http://localhost:81/flandy/getpost2.php?web=" . $website . "&pwd=" . $pwd . "&action=check&pseid=" . $psecode . "&amt=" . $amt ; curl_setopt( $ch , CURLOPT_URL, $curl_url ); curl_setopt( $ch , CURLOPT_POST, 1); curl_setopt( $ch , CURLOPT_RETURNTRANSFER, 1); //不直接输出,返回到变量 $curl_result = curl_exec( $ch ); $result = explode ( ',' , $curl_result ); curl_close( $ch ); print_r( $result ); ?> |
getpost2.php的内容如下:
1
2
3
4
5
6
|
<?php echo "returndata<br>" ; echo "<pre>" ; print_r( $_REQUEST ); echo "</pre>" ; ?> |
结果输出:
1
2
3
4
5
6
7
8
9
10
|
Array ( [0] => returndata Array ( [web] => 'wwwbaiducom' [pwd] => 123456 [action] => check [pseid] => 'NDE005' [amt] => 1 ) ) |
方法三:这个要借助第三方类库HttpClient

<?php require_once 'HttpClient.class.php' ; $params = array ( 'web' => 'www.baidu.com' , 'pwd' => '123456' , 'action' => 'check' , 'pseid' => 'NDE005' , 'amt' => 1); $pageContents = HttpClient::quickPost( 'http://localhost:81/flandy/getpost3.php' , $params ); $result = explode ( ',' , $pageContents ); print_r( $result ); ?> |
希望本文所述对大家PHP程序设计有所帮助。
