mod_python req.subprocess_env未“看到”PythonOptions

Question

我在从Apache配置中获取一个环境变量时遇到了麻烦。（别问为什么要这样做，我不是最初写这个代码的人）

这是我在Apache配置中的内容。

<Location "/var/www">
    SetHandler python-program
    PythonHandler mod_python.publisher
    PythonOption MYSQL_PWD ###########
    PythonDebug On
</Location>

这是有问题的代码...

#this is the problem code in question.
def index(req):
    req.add_common_vars()
    os.environ["MYSQL_PWD"] = req.subprocess_env["MYSQL_PWD"] 
    req.content_type = "text/html"

    statText = getStatText()

这是我执行时得到的错误追踪信息。

os.environ["MYSQL_PWD"] = req.subprocess_env["MYSQL_PWD"]

KeyError: 'MYSQL_PWD'

Answer 1

os.environ["MYSQL_PWD"] = req.get_options()["MYSQL_PWD"]
