看看代码的执行结果吧
class Foo(object):
def __init__(self, local):
object.__setattr__(self, '_Foo__local', local)
def get(self):
return self.__local
a = Foo('a')
print(a.get())
#结果a
再来一个
class Bar(object):
def __init__(self, name):
self.__name = name
b = Bar('hello')
print(b._Bar__name)
# 结果hello
Flask中关于代理的使用
from werkzeug.local import LocalStack, LocalProxy
from flask import Flask
app = Flask()
app.run()
test_stack = LocalStack()
test_stack.push({'abc': '123'})
test_stack.push({'abc': '1234'})
def get_item():
return test_stack.pop()
item = LocalProxy(get_item)
print(item['abc'])
print(item['abc'])
这个呢?
from werkzeug.local import LocalStack
test_stack = LocalStack()
test_stack.push({'abc': '123'})
test_stack.push({'abc': '1234'})
def get_item():
return test_stack.pop()
item = get_item()
print(item['abc'])
print(item['abc'])
