这是我的文件上传功能的django模型，当尝试上传具有日文名称的文件时，我的信息低于错误。

我可以上传普通文件，但是非英文名称的文件我会收到错误。

我尝试设置LANG变量，但我仍然遇到此错误。

有人可以请求帮助解决这个问题。

Answer 1

您需要正确设置您的语言环境 for Apache ;如果没有正确的语言环境，Python将回退到使用ASCII作为文件名。

将LANG环境变量设置为LANG=en_US.UTF-8到Apache envvars文件。在Debian和Ubuntu系统上，您可以在/etc/apache2/envvars，RedHat，/etc/sysconfig/httpd中找到它。

添加以下行：

EXPORT LANG=en_US.utf8

如果您无法找到envvars文件，请参阅ServerFault上的this question以获取有关如何查找该文件的更多提示。

Answer 2

默认情况下，您可能使用LANG = C语言环境运行Apache，这会破坏上传其名称中包含特殊字符的文件，至少在使用mod_wsgi运行时。

在/ etc / apache2 / envvars中激活UTF-8语言环境应解决此问题。

在httpd.conf中添加（或更改，如果它已经存在）：

AddDefaultCharset utf-8

日文名称的文件引发错误
