<html>
<body>
<form action="/upload" enctype="multipart/form-data" method="post">
<input name="myfile" type="file">
<input type="submit" value="Submit">
</form>
</body></html>
其中python中UploadHandler中的“/upload”一定要出现在index.html中的表单的action属性中，必须一致。
action和methhod 都是对当前form的提交进行设置
action="提交到地址以及相关参数"
method="设置提交方式"
