Python 具有日语名称的文件引发错误

这是我的django模型的文件上传功能，当一个用户试图上传一个有日本名字的文件时，我发现下面的错误

我可以上传普通的文件，但非英文名称的文件会出错

我尝试设置LANG变量，但仍然出现此错误

有人能帮你解决这个问题吗。

你需要为Apache设置正确的语言环境；如果没有正确的区域设置，Python会使用

ASCII

作为文件名

将

LANG

环境变量设置为Apache

envvars

文件的

LANG=en_US.UTF-8

。在Debian和Ubuntu系统上，您可以在

/etc/apache2/envvars

中，在RedHat上，在

/etc/sysconfig/httpd

中找到

添加行：

class FileUpload(models.Model):
    cstr = models.CharField(max_length=50)
    file_nm = models.CharField(max_length=250,editable=False,verbose_name='Name')
    file_type_cd = models.CharField(max_length=10,editable=False, verbose_name='Type')
    file_size_val = models.CharField(max_length=25,editable=False, verbose_name='Size in MB')
    file_upld_dts = models.DateTimeField(default =datetime.datetime.now() ,editable=False, verbose_name='Uploaded Date & Time')
    fileupload = models.FileField(upload_to=fs,verbose_name='File to Upload')
    file_title = models.CharField(max_length=250,verbose_name='Title')
    fileretention = models.IntegerField(default=18,verbose_name = '# months of Retention')
    def __unicode__(self):
        return unicode(self.file_nm)

如果您在查找

envvars

文件时遇到问题，请参阅ServerFault以获取有关如何查找该文件的更多提示。

可能您在默认情况下使用LANG=C语言环境运行Apache，这至少在使用mod_wsgi运行时会中断上载名称中带有特殊字符的文件

在/etc/apache2/envvars中激活UTF-8区域设置可以解决此问题

在httpd.conf中添加（或更改，如果已经存在）：

---

什么是

fs

（如在

models.FileField（upload_-to=fs，verbose_-name='File-to-upload'）

）设置为？fs=FileSystemStorage（location='/tmp'）你能试着把它设置成

u'/tmp'

？以及

manage.py shell

是什么，然后

导入系统；print sys.getfilesystemencoding（）

说你的文件系统编码是？@MartijnPieters不起作用你怎么知道这件事的？我在/etc/sysconfig/httpd和/etc/init.d/httpd中都设置了LANG变量，但我仍然没有退出errorDjango调试输出错误时显示环境变量；验证是否在此处设置了

LANG

。创建一个调试视图来验证

sys.getfilesystemencoding（）

，也许也可以。@MartijnPieters 20年了，是吗？别担心，我很快就会赶上的：）这很奇怪，当你通过一个视图ANSI_X3.4-1968为Apache设置字符集时，我得到了下面的值；是Python根据env vars确定了区域设置，而

AddDefaultCharset

对此没有影响。@MartijnPieters开发人员正在apache中使用mod_wsgi运行该站点。因此，我想需要在两端添加字符集。

mod_wsgi

仍然运行Python解释器（在Apache进程中或在单独的守护进程中）。Python使用的是

sys.getfilesystemencoding（）

，它在UNIX上完全基于区域设置（

LANG

和

LC.*

vars）。啊！太好了，我明白了。谢谢@MartijnPieters我补充道谢谢@MartijnPieters

EXPORT LANG=en_US.utf8

AddDefaultCharset utf-8
