在主管中运行 uwsgi 出错但在命令行中运行良好

Question

我在 supervisord 下运行 uwsgi 时遇到了一些问题。

主要问题是我用命令行运行uwsgi --ini /home/satori/mysite/src/mysite_uwsgi.ini，一切正常，但是当我在supervisorctl下运行它时，当我上传一个非ASCII字符名称的文件时，服务器返回500。

但它不会发生如果我在命令行中运行，文件已正确上传。

我认为问题与我的主管配置文件有关，可能是一些环境问题。我的配置文件在/etc/supervisord.conf

这是我的 mysite_uwsgi.ini 文件，位于/home/satori/mysite/src/mysite_uwsgi.ini

# mysite_uwsgi.ini file
[uwsgi]

# Django-related settings
# the base directory (full path)
chdir           = /home/satori/mysite/src
# Django's wsgi file
module          = mysite.wsgi
# the virtualenv (full path)
#home            = /home/ubuntu/mysite/bin

#plugins         = python34

# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 10
# the socket (use the full path to be safe
socket          = /home/satori/mysite/src/mysite.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 666
# clear environment on exit
vacuum          = true

这是 supervisord.conf 中的相关设置

[program:mysite]
command=uwsgi --ini /home/satori/mysite/src/mysite_uwsgi.ini
autostart=true
autorestart=true
user=root
log_stderr=true
stdout_logfile=/var/log/mysite.log

这是 500 错误：

UnicodeEncodeError at /upload/view/
'ascii' codec can't encode characters in position 37-38: ordinal not in range(128)

models.py

# encoding: utf-8
import os
from django.db import models
from django.conf import settings


def get_upload_path(instance, filename):
    filename = ''.join([ch for ch in filename if ord(ch) < 128])
    return os.path.join("user_%d" % instance.owner.id, filename)


class Picture(models.Model):
    """This is a small demo using just two fields. The slug field is really not
    necessary, but makes the code simpler. ImageField depends on PIL or
    pillow (where Pillow is easily installable in a virtualenv. If you have
    problems installing pillow, use a more generic FileField instead.
    """
    file = models.ImageField(upload_to=get_upload_path)
    slug = models.SlugField(max_length=50, blank=True)
    owner = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)

    def __str__(self):
        return self.file.name

    @models.permalink
    def get_absolute_url(self):
        return ('upload-new', )

    def save(self, *args, **kwargs):
        self.slug = self.file.name
        super(Picture, self).save(*args, **kwargs)

    def delete(self, *args, **kwargs):
        """delete -- Remove to leave file."""
        self.file.delete(False)
        super(Picture, self).delete(*args, **kwargs)

你应该把它添加到你的 uwsgi.ini 文件中

env = PYTHONIOENCODING=UTF-8

另外，不确定这是否是您所做的，但我使用 str 而不是 unicode。我正在使用一个需要 str 的插件，在这种情况下你可以写：

def __str__(self):
    return YourModel.__unicode__(self)
