Description: simple login interfaces
A directory structure is as follows
Two implementation steps
1 Create a folder templates, add login.html file (page) in the folder
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>login</title>
</head>
<body>
<form action="/login/" method="POST">
<h1>用户名：<input name="username"></h1>
<h1>密码：<input name="password"></h1>
<input type="submit" value="登录">
</form>
</body>
</html>
