php模拟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模拟post傳值的方法,file_get_contents、curl和socket。
第一種:file_get_contents來模拟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);
第二種:curl模拟post
function curl_post($url, $post){
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);
$data = curl_post("http://www.a.com/post/post.php", array('name'=>'caiknife','email'=>'caiknife#gmail.com'));
第三種:socket來模拟post
function socket_post($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'));
上面這三種方法最後看到的内容都是一樣的,都可以得到post的傳值;但是在是用socket的時候,發送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取得的内容是包含了header資訊的,要處理一下才能獲得真正的内容。
