Bottle是一個(gè)使用Python語言編寫的符合WSGI規(guī)范Web框架.它提供根據(jù)URL參數(shù)轉(zhuǎn)發(fā)請(qǐng)求(映射),模板,key/value數(shù)據(jù)庫,內(nèi)置多種第三方WSGI/HTTP服務(wù)器適配器和模板引擎.整個(gè)框架只有一個(gè)文件不依賴第三方擴(kuò)展庫.
安裝或依賴你可以使用easy_install bottle或下載bottle.py到你工作目錄下.Python版本要求2.5+或3.x(使用2to3轉(zhuǎn)換)
特性和例子輕量級(jí)不需要安裝和配置.你只要獲得一份bottle.py拷貝就可以編碼了!簡(jiǎn)單的"Hello World" Bottle應(yīng)用大致如下:
from bottle import route, run
@route('/')
def index():
return 'Hello World!'
run(host='localhost', port=8080)就是這么簡(jiǎn)單.運(yùn)行它并打開瀏覽器訪問http://localhost:8080/.
良好的URL風(fēng)格根據(jù)映射語法提取動(dòng)態(tài)URL參數(shù).
@route('/hello/:name')
def hello(name):
return 'Hello, %s' % name獲取使用完整的正則去匹配.
@route('/friends/(?<name>(Alice|Bob))')
def friends(name):
return 'Hello, %s! Good to see you :)' % name靜態(tài)文件,重定向和HTTP錯(cuò)誤下面的方法可以方便的處理日常工作.
from bottle import send_file, redirect, abort
@route('/static/:filename')
def static_file(filename):
send_file(filename, root='/path/to/static/files')
@route('/wrong/url')
def wrong():
redirect("/right/url")
@route('/restricted')
def restricted():
abort(401, "Sorry, access denied.")POST,GET,Header和Cookies可以當(dāng)做一個(gè)簡(jiǎn)單的dict()來使用
from bottle import request, response
@route('/hello/cookie')
def cookie():
name = request.COOKIES.get('name', 'Stranger')
response.header['Content-Type'] = 'text/plain'
return 'Hello, %s' % name
@route('/hello/cookie', method='POST')
def set_cookie():
if 'name' in request.POST:
name = request.POST['name']
response.COOKIES['name'] = name
return 'OK'模板Bottle自帶了一個(gè)簡(jiǎn)單快速的輕量級(jí)模板引擎
@get('/hello/template/:names')
def pretty_hello(names):
names = names.split(',')
return template('hello', title='Hello World', names=names)這里是模板:
<html>
<head>
<title>{{title}}</title>
</head>
<body>
%for name in names:
<p>Hello, <strong>{{name}}</strong></p>
%end
</body>
</html>也可以使用mako模板獲得更多功能
from bottle import mako_template as templateHTTP服務(wù)器Bottle自帶了HTTP服務(wù)器,當(dāng)然也支持在cherrypy, flup,paste和fapws3運(yùn)行應(yīng)用.
from bottle import PasteServer
run(server=PasteServer)缺少的特性和Bug缺陷Bottle不包括:
- ORM:你可以選擇(SQLAlchemy, Elixir)
- HTML幫助類,會(huì)話,認(rèn)證:自己動(dòng)手吧
- 擴(kuò)展:抱歉還沒有
有些可能不會(huì)工作:
- 在Python 3.x下多文件上傳會(huì)有問題,因?yàn)閏gi.FileStorage修改了.
Benchmark本地使用ApacheBench在我的AMD 2800+(2GB)測(cè)試Bottle 0.4.2 run(server=PasteServer)
