本文介绍了在Django管理中上传文件时出现UnicodeEncodeError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的问题与相似，但提出的解决方案不适合我。我试图通过Django管理应用程序上传一个名为Testaråäö.txt的文件。
我正在用Gunicorn 0.13.4和Nginx运行Django 1.3.1 0.7.6.7在Debian 6服务器上。数据库是PostgreSQL 8.4.9。其他的Unicode数据保存到数据库没有问题，所以我想这个问题一定是用文件系统。
我已经设置了
http {
charset utf-8;
}
在我的nginx.conf中。 LC_ALL和LANG被设置为'sv_SE.UTF-8'。运行语言环境验证这一点。我甚至尝试在我的nginx初始化脚本中设置LC_ALL和LANG，以确保locale设置正确。

解决方案
看来，运行django服务的服务是apache，gunicorn + supervisor ，守护进程等...并不总是使用正确的环境变量。在这种情况下，监督员启动gunicorn，所以你必须明确告诉主管使用环境选项来使用utf-8：
$ b $
environment = LANG = en_US.UTF-8，LC_ALL = en_US.UTF-8，LC_LANG = en_US.UTF-8
My question is similar to the one reported here, but the proposed solution doesn't work for me. I'm trying to upload a file called 'Testaråäö.txt' via the Django admin app.
I'm running Django 1.3.1 with Gunicorn 0.13.4 and Nginx 0.7.6.7 on a Debian 6 server. Database is PostgreSQL 8.4.9. Other Unicode data is saved to the database with no problem, so I guess the problem must be with the filesystem somehow.
I've set
http {
charset utf-8;
}
in my nginx.conf. LC_ALL and LANG is set to 'sv_SE.UTF-8'. Running 'locale' verifies this. I even tried setting LC_ALL and LANG in my nginx init script just to make sure locale is set properly.
Here's the traceback:

UPDATE: I tried running Gunicorn with debugging turned on, and the file uploads without any problem at all. I suppose this must mean that the issue is with Nginx. Still beats me where to look, though. Here are the raw response headers from Gunicorn and Nginx, if it makes any sense:
Gunicorn:

解决方案
It seems that it is a common problem that the service that runs the django service, be it apache, gunicorn + supervisor, daemontools, etc... doesn't always use the correct environment variables.
In this case, gunicorn is started by supervisor, so you have to explicitly tell supervisor to use utf-8 using the environment option:
environment=LANG=en_US.UTF-8, LC_ALL=en_US.UTF-8, LC_LANG=en_US.UTF-8
