php模拟post传值在日常的工作中用到的不是很多,但是在某些特定的场合还是经常用到的。
下面,我整理了三种php模拟post传值的方法,file_get_contents、curl和socket。
?
第一种:file_get_contents来模拟post
?
- <?php
- ?
- function file_get_contents_post($url, $post){
- ?
-     $options = array(
- ‘http‘=> array(
- ‘method‘=>‘POST‘,
- ‘content‘=> http_build_query($post),
- ),
- );
- ?
-     $result = file_get_contents($url,false, stream_context_create($options));
- return $result;
- ?
- }
- ?
- $data = file_get_contents_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));
- var_dump($data);
?
第二种:curl模拟post
?
- <?php
- ?
- function curl_post($url, $post){
- ?
-     $options = array(
-         CURLOPT_RETURNTRANSFER =>true,
-         CURLOPT_HEADER         =>false,
-         CURLOPT_POST           =>true,
-         CURLOPT_POSTFIELDS     => $post,
- );
- ?
- ?
-     $ch = curl_init($url);
-     curl_setopt_array($ch, $options);
-     $result = curl_exec($ch);
-     curl_close($ch);
- return $result;
- }
- ?
- $data = curl_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));
- ?
- var_dump($data);
?
第三种:socket来模拟post
?
- <?php
- ?
- function socket_post($url, $post){
-     $urls = parse_url($url);
- if(!isset($urls[‘port‘])){
-         $urls[‘port‘]=80;
- }
- ?
-     $fp = fsockopen($urls[‘host‘], $urls[‘port‘], $errno, $errstr);
- if(!$fp){
-         echo "$errno, $errstr";
- exit();
- }
- ?
-     $post = http_build_query($post);
-     $length = strlen($post);
-     $header =<<<HEADER
- ?
- <span class="Apple-tab-span" style="white-space:pre"></span>POST {$urls[‘path‘]} HTTP/1.1
- <span class="Apple-tab-span" style="white-space:pre"></span>Host:{$urls[‘host‘]}
- <span class="Apple-tab-span" style="white-space:pre"></span>Content-Type: application/x-www-form-urlencoded
- <span class="Apple-tab-span" style="white-space:pre"></span>Content-Length:{$length}
- <span class="Apple-tab-span" style="white-space:pre"></span>Connection: close
- <span class="Apple-tab-span" style="white-space:pre"></span>{$post}
- <span class="Apple-tab-span" style="white-space:pre"></span>HEADER;
- ?
-     fwrite($fp, $header);
-     $result =‘‘;
- while(!feof($fp)){
-         $result .= fread($fp,512);
- }
-     $result = explode("\r\n\r\n", $result,2);
- return $result[1];
- ?
- }
- ?
- $data = socket_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));
- var_dump($data);
?
上面这三种方法最后看到的内容都是一样的,都可以得到post的传值;但是在是用socket的时候,发送header信息时必须要注意header的完整信息,比如content type和content length必须要有,connection: close和post数据之间要空一行,等等;而通过socket取得的内容是包含了header信息的,要处理一下才能获得真正的内容。
