python环境搭建
1.安装python(Ubuntu自带2.7.4，其实可以不用重装)
wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz
tar -zxvf Python-2.7.6.tgz
cd Python-2.7.6
./configure
make
sudo make install
然后使用 python -V 查看版本 >> Python 2.7.6
参考：http://lutaf.com/141.htm
2.安装setuptools (无需最新2.0，使用0.9.8即可)
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-0.9.8.tar.gz#md5=243076241781935f7fcad370195a4291（这是setuptools-0.9.8压缩包下载地址）
tar -zxvf setuptools-0.9.8.tar.gz
cd setuptools-0.9.8
sudo python setup.py build
sudo python setup.py install
然后使用sudo easy_install 如果返回error: No urls, filenames, or requirements specified (see --help)表示安装成功
3.安装web.py
sudo easy_install web.py
然后,新建文件server.py(任意目录)，并运行python server.py,然后打开浏览器输入http://localhost:8080/
import web
urls = (
'/(.*)', 'hello'
)
app = web.application(urls, globals())
class hello:
def GET(self, name):
if not name:
name = 'World'
return 'Hello, ' + name + '!'
if __name__ == "__main__":
app.run()
4.安装mysql
sudo apt-get install mysql-server
安装完成之后输入
mysql -u root -p
然后创建测试数据库test
mysql> show databases;
mysql> create database test;
mysql> use test;
创建测试数据表
CREATE TABLE post_list (
id INT AUTO_INCREMENT,
title TEXT,
content TEXT,
primary key (id)
);
insert into post_list (title,content) values ('hello','This is hello world');
5.简单博客API, app.py
#!/usr/local/bin/python
#coding=utf-8
import web
import json
# routes
urls = (
'/hello/(.*)', 'Hello',
'/', 'List',
'/view/(\d+)', 'View',
'/new', 'New',
'/delete/(\d+)', 'Delete',
'/edit/(\d+)', 'Edit',
)
app = web.application(urls, globals())
# database instance
db = web.database(dbn = 'mysql', db = 'test', user = 'root', pw = 'password')
# Hello World
class Hello:
def GET(self, name = 'World'):
return 'Hello, ' + name + '!'
#查看文章类
class View:
def GET(self, id):
try:
return json.dumps(db.select('post_list', where = 'id='+str(int(id)), vars = locals())[0])
except IndexError:
return None
#首页类
class List:
def GET(self):
posts = db.select('post_list', order = 'id DESC')
return json.dumps(posts.list())
#新建文章类
class New:
def GET(self):
form = web.input()
db.insert('post_list',
title = form.title,
content = form.content)
raise web.seeother('/')
#删除文章类
class Delete:
def GET(self, id):
db.delete('post_list', where = 'id = ' + str(int(id)), vars = locals())
raise web.seeother('/')
#编辑文章类
class Edit:
def GET(self, id):
form = web.input()
db.update('post_list',
where = ' id = ' + str(int(id)),
vars = locals(),
title = form.title,
content = form.content)
raise web.seeother('/')
#定义404错误显示内容
def notfound():
return web.notfound("Sorry, the page you were looking for was not found.")
app.notfound = notfound
#运行
if __name__ == '__main__':
app.run()
6.运行python app.py, 通过浏览器访问http://localhost:8080/就能看到了
