我在uwsgi / emeror / Nginx服务器上编码有很大问题.
我的应用程序开发为批处理excel文件处理.

我使用最新版本的烧瓶和烧瓶扩展,并使用flask-excel.

我的应用程序在Digital Ocean / ubuntu服务器上运行,我的配置文件是：

/etc/init/uwsgi.conf

description "uWSGI"
start on runlevel [2345]
stop on runlevel [06]
respawn

env UWSGI=/home/lukas/www/abissk/venv/bin/uwsgi
env LOGTO=/home/lukas/logs/abissk/emperor.log
exec $UWSGI --master --emperor /etc/uwsgi/vassals --die-on-term --uid www-data --gid www-data --logto $LOGTO  

/etc/uwsgi/vassals/abissk_uwsgi.ini

[uwsgi]
plugins = python
#pcre = True

#application's base folder
base = /home/lukas/www/abissk/

#enable-threads = true

#python module to import
app = wsgi
module = %(app) 

home = %(base)venv
pythonpath = %(base)

#socket file's location
socket = /home/lukas/www/abissk/%n.sock

#permissions for the socket file
chmod-socket = 644

#the variable that holds a flask application inside the module imported at line #6
callable = app

#location of log files
logto = /home/lukas/logs/abissk/%n.log

/home/lukas/www/abissk/wsgi.py

# -*- coding: utf-8 *-*
from app.app import create_app
from app.settings import ProdConfig

app = create_app(config_object=ProdConfig)

在/ etc / Nginx的/启用的站点 – / abissk_Nginx

server {
    listen 80;
    server_name benela.abis.sk; 
    charset     utf-8;
    client_max_body_size 75M;

    location / { try_files $uri @yourapplication; }
    location @yourapplication {
        include uwsgi_params;
        uwsgi_pass unix:/home/lukas/www/abissk/abissk_uwsgi.sock;
    }

}

这是我的问题：
使用命令启动应用程序时：

 ~/www/abissk/venv/bin/uwsgi --ini /etc/uwsgi/vassals/abissk_uwsgi.ini

并上传excel文件工作得很好但是

当使用emperor与完全相同的配置文件(在/etc/init/uwsgi.conf中)启动相同的应用程序时,应用程序工作正常,但是当上传excel文件到批处理时,我只看到消息：“502 Bad Gateway”并在我的日志中是：

 UnicodeEncodeError: 'ascii' codec can't encode character '\xfd' in position 31: ordinal not in range(128)

我尝试使用apt-get / pip3安装安装uwsgi并且场景相同：当没有皇帝直接运行应用程序时,工作正常;当使用emperor运行应用程序(具有相同配置)时,每个上传excel文件到我的应用程序以崩溃结束：/

谢谢你的回答
