前言

已经想学开发网站很久了，奈何只会Python，但不会HTML语言。

一、web2py

当初学时觉得最容易上手的工具。

二、使用步骤

1.找到一个可以帮助网站运营的工具——pythonanywhere

入口：https://www.pythonanywhere.com/

1）创建账户；

Start running……;

Create a Beginner account;

注册;

创建成功;

2）创建网站

点击Open Web tab后Add a new web app（我已经有一个创建好的网站被我停用了，这时免费的网站只能创建一个，所以需要删除原来的网站才能创建新的）;

一路next(什么注册选择都自己选）;

using this domain already exists说明网络仓库已经有这个文件夹了，而创建新的网站APP需要空的文件路径，因此直接把上面的Directory路径修改一下就好了，Admin Password是网站管理密码（创建需要等待几分钟）；

成功创建，接下来是网站管理了；

每当你对网站进行修改后，若是刷新网站后没有更新，则是要点击下面的绿色按钮Reload ……；

若是你想一直让这个网站运行下去，则是要每隔三个月点击黄色按钮Run……；

以我的注册网站为例，进入welcome

这是网站的后台入口界面，点击蓝色按钮admin；

对menu.py

主要是看上面的菜单栏有些不爽，将他们都隐去。

记得保存。

修改default.py

由于需要自定义网站，所以需要将默认网站接口进行修改。将代码修改以下：

# -*- coding: utf-8 -*-
# -------------------------------------------------------------------------
# This is a sample controller
# this file is released under public domain and you can use without limitations
# -------------------------------------------------------------------------

# ---- example index page ----
def index():
    return auth.wiki() 

# ---- API (example) -----
@auth.requires_login()
def api_get_user_email():
    if not request.env.request_method == 'GET': raise HTTP(403)
    return response.json({'status':'success', 'email':auth.user.email})

# ---- Smart Grid (example) -----
@auth.requires_membership('admin') # can only be accessed by members of admin groupd
def grid():
    response.view = 'generic.html' # use a generic view
    tablename = request.args(0)
    if not tablename in db.tables: raise HTTP(403)
    grid = SQLFORM.smartgrid(db[tablename], args=[tablename], deletable=False, editable=False)
    return dict(grid=grid)

# ---- Embedded wiki (example) ----
def wiki():
    auth.wikimenu() # add the wiki to the menu
    return auth.wiki() 

# ---- Action for login/register/etc (required for auth) -----
def user():
    """
    exposes:

    use @auth.requires_login()
        @auth.requires_membership('group name')
        @auth.requires_permission('read','table name',record_id)
    to decorate functions that need access control
    also notice there is http://..../[app]/appadmin/manage/auth to allow administrator to manage users
    """
    return dict(form=auth())

# ---- action to server uploaded static content (required) ---
@cache.action()
def download():
    """
    allows downloading of uploaded files
    http://..../[app]/default/download/[filename]
    """
    return response.download(request, db)

视图修改layout.html
