与Beaker进行Bottle.py会话 [英] Bottle.py session with Beaker

问题描述

第一次提问者.

我目前正在努力使用Bottle微型框架正确使用Beaker.这是有问题的程序:

I'm currently struggling on how to use Beaker properly using the Bottle micro-framework. Here's the problematic program:

#!/usr/bin/python
# -*- coding: utf-8 -*-
# filename: server.py

import bottle as app
from beaker.middleware import SessionMiddleware

session_options = {
    'session.type': 'file',
    'session.data_dir': './session/',
    'session.auto': True,
}
app_middlware = SessionMiddleware(app.app(), session_options)
app_session = app.request.environ.get('beaker.session')

@app.route('/login')
def login():
    app_session = app.request.environ.get('beaker.session')
    app_session['logged_in'] = True

@app.route('/logout')
def logout():
    app_session = app.request.environ.get('beaker.session')
    if app_session.get('logged_in'):
        app_session['logged_in'] = False
        return 'You are logged out'
    app.redirect('/login')

@app.route('/dashboard')
def dashboard():
    app_session = app.request.environ.get('beaker.session')
    if app_session.get('logged_in'):
        return 'You are logged in'
    app.redirect('/login')

app.debug(True)
app.run(app=app_middlware, reloader=True)

如果您注意到了，我会继续在每个def块上调用app_session = app.request.environ.get('beaker.session')，这样它就不会返回类似以下的错误:TypeError: 'NoneType' object does not support item assignment ---似乎Python无法识别其功能之外的变量(如果我错了，请纠正我).

If you noticed, I keep on calling app_session = app.request.environ.get('beaker.session') on every def block so just it will not return an error like: TypeError: 'NoneType' object does not support item assignment --- it seems that Python doesn't recognize variables that is outside its function (correct me if I'm wrong).

这是问题:

1. 我应该怎么做才能只有一个app_session = app.request.environ.get('beaker.session')实例，以便每个def块都可以使用它(我真的需要一个实例，因为它是要检查和使用的同一会话).
2. 如果这是唯一的方法(虽然很丑)，那么我是否应该仅合并需要会话的所有路由，以便可以实现app_session的单个实例?

1. What should I do to only have one instance of app_session = app.request.environ.get('beaker.session') so it can be available to every def blocks (I really need one instance since it's the same session to be checked and used).
2. If this is the only way (it's ugly though), then should I just combine all routes that requires a session just so I can achieve the single instance of app_session?

类似的东西:

@app.route('/<path:re:(login|dashboard|logout)\/?>')
def url(path):
    app_session = app.request.environ.get('beaker.session')
    if 'login' in path:
        app_session['logged_in'] = True
    elif 'logout' in path:
        if app_session.get('logged_in'):
            # app_session.delete() it doesn't seem to work?
            app_session['logged_in'] = False
            return 'You are logged out'
        app.redirect('/login')
    elif 'dashboard' in path:
        if app_session.get('logged_in'):
            return 'You are logged in'
        app.redirect('/login')

推荐答案

在bottle应用程序中使用beaker很容易.首先，设置您的Bottle应用程序:

Using beaker in your bottle application is easy. First, set up your Bottle app:

import bottle
from bottle import request, route, hook
import beaker.middleware

session_opts = {
    'session.type': 'file',
    'session.data_dir': './session/',
    'session.auto': True,
}

app = beaker.middleware.SessionMiddleware(bottle.app(), session_opts)

随后:

bottle.run(app=app)

有了这个选项，每次您收到请求时，您的Beaker会话都将以 request.environ['beaker_session'].为了方便起见，我通常会这样做:

With this in place, every time you receive a request, your Beaker session will be available as request.environ['beaker_session']. I usually do something like this for convenience:

@hook('before_request')
def setup_request():
    request.session = request.environ['beaker.session']

这可以安排在处理任何请求之前运行setup_request；我们使用的是bottle.request变量(请参见前面的import语句)，它是线程局部变量，其中包含有关当前请求的信息.从现在开始，只要需要，我就可以引用request.session，例如:

This arranges to run setup_request before handling any request; we're using the bottle.request variable (see the earlier import statement), which is a thread-local variable with information about the current request. From this point on, I can just refer to request.session whenever I need it, e.g.:

@route('/')
def index():
    if 'something' in request.session:
       return 'It worked!'

    request.session['something'] = 1
