CentOS 7 / Apache / mod_wsgi - UnicodeDecodeError：'ascii' 编解码器无法解码位置 2727 中的字节 0xc2：序数不在范围内(128)

我已经使用 mod_wsgi 在 Apache（httpd）中部署了一个 Python Web 应用程序（使用 Pyramid）。

启动 Apache 服务后，当我们向 Web 应用程序发出 http 请求时，会发生以下错误（来自 Apache 日志）...

该 Web Python 应用程序在所有这些发行版中均可完美运行：Ubuntu 14.04、Debian 8、RedHat 6、CentOS 6、Suse 12 和 openSUSE 13，但在 CentOS 7 中则不行... =[

我们在“CentOS 7”中使用“Python 3.2.2”、“mod_wsgi 4.3.2”和“Apache 2.4.6”。Web应用程序建立在 Pyramid Web Framework 之上（http://docs.pylonsproject.org/projects/pyramid/en/latest/）。

这是一个相当常见的错误！到目前为止，我还没有找到获取有关此错误的更多信息的方法。

我们已经尝试了所有方法来解决这个问题，但我们就是不知道为什么会发生这种情况... =[

请帮我！

答案1

出现此问题的原因是CentOS 7 的文件包含对 ascii 无效的 /etc/mime.types字符"³"（line ）（未扩展）。 为了解决这个问题，我不得不对我的 Python 3.2.2 进行一些修改并重新加载我的应用程序。 解决方案是删除该字符或任何其他无效（ascii）字符！ @MichaelHampton "application/vnd.geocube+xml g3 g³"



"³"


谢谢！
