修改index.py
#!/usr/bin/env Python # coding=utf-8 import tornado.web import methods.readdb as mrd class IndexHandler(tornado.web.RequestHandler): def get(self): usernames = mrd.select_columns(table="users",column="username") one_user = usernames[0][0] self.render("index.html", user=one_user) def post(self): username = self.get_argument("username") password = self.get_argument("password") user_infos = mrd.select_table(table="users",column="*",condition="username",value=username) if user_infos: db_pwd = user_infos[0][2] if db_pwd == password: self.write("welcome you: " + username) else: self.write("your password was not right.") else: self.write("There is no thi user.")
readdb.py 添加select_columns 方法
def select_columns(table, column ): sql = "select " + column + " from " + table cur.execute(sql) lines = cur.fetchall() return lines
修改index.html文件
<!DOCTYPE html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1" /> <title>Learning Python</title> </head> <body> <h2> 登录页面</h2> <p>用用户名为：{{user}}登录</p> <form method="POST"> <p><span>UserName:</span><input type="text" id="username"/></p> <p><span>Password:</span><input type="password" id="password" /></p> <p><input type="BUTTON" value="登录" id="login" /></p> </form> <script src="{{static_url(‘js/jquery-3.2.1.min.js‘)}}"></script> <script src="{{static_url(‘js/script.js‘)}}"></script> </body>
要求用户正确登录之后，跳转到另外一个页面，并且在那个页面中显示出用户的完整信息。
先修改 url.py 文件，在其中增加一些内容
#!/usr/bin/env Python # coding=utf-8 """ the url structure of website """ #!/usr/bin/env Python # coding=utf-8 """ the url structure of website """ from handlers.index import IndexHandler from handlers.user import UserHandler url = [ (r‘/‘, IndexHandler), (r‘/user‘, UserHandler), ]
然后就建立 handlers/user.py 文件
#!/usr/bin/env Python # coding=utf-8 import tornado.web import methods.readdb as mrd class UserHandler(tornado.web.RequestHandler): def get(self): username = self.get_argument("user") user_infos = mrd.select_table(table="users",column="*",condition="username",value=username) self.render("user.html", users = user_infos)
