我用Bottle做了一些编码。它非常简单,符合我的需求。但是,当我试图将应用程序包装到一个类中时,我坚持了下来:
import bottle
app = bottle
class App():
def __init__(self,param):
self.param = param
# Doesn't work
@app.route("/1")
def index1(self):
return("I'm 1 | self.param = %s" % self.param)
# Doesn't work
@app.route("/2")
def index2(self):
return("I'm 2")
# Works fine
@app.route("/3")
def index3():
return("I'm 3")
是否可以在Bottle中使用方法而不是函数?
答案 0 :(得分:39)
您的代码无效,因为您尝试路由到非绑定方法。非绑定方法没有self
的引用,如果尚未创建App
的实例,它们怎么可能?
如果要路由到类方法,首先必须初始化类,然后bottle.route()
初始化该对象上的方法,如下所示:
import bottle
class App(object):
def __init__(self,param):
self.param = param
def index1(self):
return("I'm 1 | self.param = %s" % self.param)
myapp = App(param='some param')
bottle.route("/1")(myapp.index1)
如果要在处理程序附近粘贴路径定义,可以执行以下操作:
def routeapp(obj):
for kw in dir(app):
attr = getattr(app, kw)
if hasattr(attr, 'route'):
bottle.route(attr.route)(attr)
class App(object):
def __init__(self, config):
self.config = config
def index(self):
pass
index.route = '/index/'
app = App({'config':1})
routeapp(app)
不要在bottle.route()
中执行App.__init__()
部分,因为您将无法创建两个App
类的实例。
如果您喜欢装饰器的语法而不是设置属性index.route=
,那么您可以编写一个简单的装饰器:
def methodroute(route):
def decorator(f):
f.route = route
return f
return decorator
class App(object):
@methodroute('/index/')
def index(self):
pass

下面很适合我:) 面向对象,易于遵循。
from bottle import Bottle, template
class Server:
def __init__(self, host, port):
self._host = host
self._port = port
self._app = Bottle()
self._route()
def _route(self):
self._app.route('/', method="GET", callback=self._index)
self._app.route('/hello/<name>', callback=self._hello)
def start(self):
self._app.run(host=self._host, port=self._port)
def _index(self):
return 'Welcome'
def _hello(self, name="Guest"):
return template('Hello {{name}}, how are you?', name=name)
server = Server(host='localhost', port=8090)
server.start()
答案 2 :(得分:24)
您必须扩展Bottle
课程。它的实例是WSGI Web应用程序。
from bottle import Bottle
class MyApp(Bottle):
def __init__(self, name):
super(MyApp, self).__init__()
self.name = name
self.route('/', callback=self.index)
def index(self):
return "Hello, my name is " + self.name
app = MyApp('OOBottle')
app.run(host='localhost', port=8080)
大多数例子都在做,包括之前提供给这个问题的答案,都是重复使用&#34;默认应用程序&#34;,而不是创建自己的应用程序,而不是使用面向对象和继承的便利。

我接受了@Skirmantas的回答并对其进行了一些修改以允许在装饰器中使用关键字参数,如方法,跳过等:
def routemethod(route, **kwargs):
def decorator(f):
f.route = route
for arg in kwargs:
setattr(f, arg, kwargs[arg])
return f
return decorator
def routeapp(obj):
for kw in dir(obj):
attr = getattr(obj, kw)
if hasattr(attr, "route"):
if hasattr(attr, "method"):
method = getattr(attr, "method")
else:
method = "GET"
if hasattr(attr, "callback"):
callback = getattr(attr, "callback")
else:
callback = None
if hasattr(attr, "name"):
name = getattr(attr, "name")
else:
name = None
if hasattr(attr, "apply"):
aply = getattr(attr, "apply")
else:
aply = None
if hasattr(attr, "skip"):
skip = getattr(attr, "skip")
else:
skip = None
bottle.route(attr.route, method, callback, name, aply, skip)(attr)

尝试这个,为我工作,文档开始也相当不错......
