以下是html代码：
<form action="/download3.php" method="post">
<input type="hidden" value="download" name="action">
<input type="hidden" value="25036" name="id">
<input type="hidden" value="7bfe3df68502dc18dfeeeb57" name="uhash">
<input name="imageField" type="image" width="140" height="55" src="http://style.bttiantang.cc/style/download.gif" style="cursor:pointer;">
</form>
我使用 simple_html_dom 工具在操作 /download3.php 之前添加根网址。但它失败了。是否可以模拟下载操作？
我使用chrome控制台获取以下数据： 请求标题

Referer，Origin和Content-Length是不同的。 服务器是否可以检查Referer和Origin？ 内容的哪些部分构成内容长度？ 是否有可能改变3个人？
