如何将wsgi.url_scheme设置为瓶中的https？

Question

我想将所有请求重定向http到https.

是否有一个通用的方法来设置wsgi.url_scheme,以https在Python 2.7瓶的应用程序？

该应用程序的一般结构是:

setup.py  // contains 'install_requires'  
wsgi  
 - myapplication.py  // the custom application containing bottle routes

wsgi.url_scheme 似乎与环境变量有关:

http://wsgi.readthedocs.org/en/latest/definitions.html#envvar-wsgi.url_scheme

但我不确定如何实际"设置"环境变量https以及是否可以在setup.py或myapplication.py文件中完成.

这里有一段代码:

https://github.com/defnull/bottle/issues/347

def i_am_https_dammit(app):
    def https_app(environ, start_response):
        environ['wsgi.url_scheme'] = 'https'
        return app(environ, start_response)
    return https_app

但是我不知道如何实现这个要点,因为我对应用程序的调用是来自软木塞而且只是使用:

application=default_app()  
session_opts = {
    'session.cookie_expires': True,
    'session.encrypt_key': 'please use a random key and keep it secret!',
    'session.httponly': True,
    'session.timeout': 3600 * 24,  # 1 day
    'session.type': 'cookie',
    'session.validate_key': True,
}
application = SessionMiddleware(application, session_opts)

如果我不理解您的问题,请原谅我,但为什么不为您的Bottle应用程序安装一个简单的重定向插件？像这样的东西:

import bottle

app = bottle.app()

def redirect_http_to_https(callback):
    '''Bottle plugin that redirects all http requests to https'''

    def wrapper(*args, **kwargs):
        scheme = bottle.request.urlparts[0]
        if scheme == 'http':
            # request is http; redirect to https
            bottle.redirect(bottle.request.url.replace('http', 'https', 1))
        else:
            # request is already https; okay to proceed
            return callback(*args, **kwargs)
    return wrapper

bottle.install(redirect_http_to_https)

@bottle.route('/hello')
def hello():
    return 'hello\n'

bottle.run(host='127.0.0.1', port=8080)

用卷曲测试:

% 05:57:03 !3000 ~>curl -v 'http://127.0.0.1:8080/hello'
* Connected to 127.0.0.1 (127.0.0.1) port 8080 (#0)
> GET /hello HTTP/1.1
> User-Agent: curl/7.30.0
> Host: 127.0.0.1:8080
> Accept: */*
>
* HTTP 1.0, assume close after body
< HTTP/1.0 303 See Other

< Location: https://127.0.0.1:8080/hello
< Content-Type: text/html; charset=UTF-8

有关插件如何工作的详细信息,请参阅Bottle文档.

简而言之,该插件通过拦截所有请求和检查协议("方案")来工作.如果方案是"http",则插件指示Bottle将HTTP重定向返回到相应的安全(https)URL.
