php模擬post傳值在日常的工作中用到的不是很多,但是在某些特定的場合還是經常用到的。
下面,我整理了三種php模擬post傳值的方法,file_get_contents、curl和socket。
第一種:file_get_contents來模擬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);
第二種:curl模擬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);
第三種:socket來模擬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);
上面這三種方法最後看到的內容都是一樣的,都可以得到post的傳值;但是在是用socket的時候,傳送header資訊時必須要注意header的完整資訊,比如content type和content length必須要有,connection: close和post資料之間要空一行,等等;而通過socket取得的內容是包含了header資訊的,要處理一下才能獲得真正的內容。
