访问Plone实例环境变量的方法

访问Plone实例环境变量的方法

我们在配置Plone实例时，通常会配置某些环境变量参数：

……
zserver-threads = 8
# If you want Zope to know about any additional eggs, list them here.
# e.g. eggs = ${buildout:eggs} my.package
eggs =    

    ${eggs:main}

environment-vars =

    zope_i18n_allowed_languages zh_CN zh_TW en zh 
    zope_i18n_compile_mo_files false
……



在Plone 模块中可以参考下面代码，访问预定义的环境变量：

import os

COMPILE_MO_FILES_KEY = 'zope_i18n_compile_mo_files'
COMPILE_MO_FILES = os.environ.get(COMPILE_MO_FILES_KEY, False)
 ALLOWED_LANGUAGES_KEY = 'zope_i18n_allowed_languages'
ALLOWED_LANGUAGES = os.environ.get(ALLOWED_LANGUAGES_KEY, None)
 if ALLOWED_LANGUAGES is not None:
     ALLOWED_LANGUAGES = ALLOWED_LANGUAGES.strip().replace(',', ' ')
ALLOWED_LANGUAGES = frozenset(ALLOWED_LANGUAGES.split())
