页面完成后的最终布局
可以看到，页面共同的部分是顶部导航和底部导航
所以我们可以把页面顶部导航和底部导航部分单独定义一个文件home.html，然后让需要使用顶部导航和底部导航的页面都继承home.html页面
1.创建父模板home.html
在templates目录的home目录下创建home.html页面，用来定义页面顶部导航和底部导航部分

2.1 定义登录视图函数login
@home.route("/login/", methods=['GET', 'POST'])
def login():
form = LoginForm()
if form.validate_on_submit(): # 如果用户输入的用户名和密码符合验证条件
data = form.data # 获取用户输入的表单数据

elif not user.check_pwd(data.get("pwd")): # 如果从数据库查询到用户名但密码不匹配
flash("用户名或密码错误！", "err")
return redirect(url_for("home.login"))
session['user'] = user.name # 定义session信息
session['user_id'] = user.id
userlog = Userlog( # 定义用户登录日志
user_id=user.id,
ip=request.remote_addr
)
db.session.add(userlog) # 添加用户登录日志
db.session.commit()
return redirect(url_for("home.user"))
return render_template("home/login.html", form=form)2.2 在home目录下创建登录前端页面login.html，继承home.html页面

3.1 定义退出视图函数logout
@home.route("/logout/")
def logout():
session.pop("user", None) # 从session中删除用户名
session.pop("user_id", None) # 从session中删除用户id
return redirect(url_for("home.login"))3.2 在home目录下创建登录前端页面logout.html，继承home.html页面
