GET的html：
<html>
<body>
<form action="http://localhost:8099" method="get">
<input name="a" type="text" value="Hello" />
<input name="" type="submit" value="提交" />
</form>
</body>
</html>
POST的html：
<form action="http://localhost:8099" enctype="MULTIPART/FORM-DATA"
method="POST">
<INPUT NAME="userfile1" TYPE="file">
<input type="submit" value="submit"/>
</form>
POST其实是水的，因为看书里面获取上传的文件内容那段代码太长了，不想写。。就直接数了一下前面报文有多少字，直接从那后面开始读了。
