AttributeError: 'WSGIRequest' object has no attribute 'app'
按照建议 here，我在本地计算机上使用这些命令构建 Saleor 仪表板，然后将其复制到远程服务器：
cd ~/repos/fork/saleor-dashboard
git checkout 2.11.1
npm14 --verbose install
export API_URI="https://api.mydomain.com/graphql/"
export GTM_ID="GTM-K9ZZ3R8"
npm14 run build
ls build/dashboard/
scp -i ~/Documents/webserver-key-pair.pem -r build/dashboard ec2-user@3.1.16.71:/srv/www/mydomain/
问题
仪表板可在线使用。但是当我使用有效的 user/pass 登录时，Saleor API 抛出这些错误，由 sudo journalctl -xe:

备注
当我 运行 在 API 和本地仪表板时，在 localhost 或 127.0.0.1 上，一切都很好。当我 运行 API 服务器并在其上部署仪表板时抛出上述错误。
更新
我正在使用 NGINX 为 Saleor API、仪表板和店面提供服务：
server {
server_name mydomain.com;
root /srv/www/mydomain.com/storefront;
location / {
index index.html index.htm;
}
}
server {
server_name dashboard.mydomain.com;
root /srv/www/mydomain.com/dashboard;
location / {
index index.html index.htm;
}
}
server {
server_name api.mydomain.com;
location / {
proxy_pass http://127.0.0.1:8000/;
}
location /graphql {
proxy_pass http://127.0.0.1:8000/graphql/;
}
}
我觉得既然网络应用程序是 WSGI 一个，NGINX 配置应该不同。有什么想法吗？
更新：测试 NGINX
之前我在本地运行SaleorAPI和Saleor店面时，没有报错
但是我做了一个测试。我什至将 NGINX 用于 localhost 通信：
server {
listen 8001;
server_name localhost;
location / {
proxy_pass http://127.0.0.1:8000/;
}
location /graphql {
proxy_pass http://127.0.0.1:8000/graphql/;
}
}
然后我开始店面：
cd ~/repos/fork/saleor-storefront
export GTM_ID="GTM-K7ZZ3R1"
export API_URI="http://localhost:8001/graphql/"
npm14 start
ℹ ｢wds｣: Project is running at http://localhost:3000/
然后浏览器DevTools控制台抛出同样的错误：
结论
看起来 NGINX 是问题的原因。
通过 uwsgi 模块启动后端 Django 服务器解决了问题：
cd /home/ec2-user/repos/fork/saleor
source saleor-venv/bin/activate
export DEBUG="False"
export ALLOWED_CLIENT_HOSTS="localhost,127.0.0.1,dashboard.mydomain.com,mydomain.com,api.mydomain.com"
export ALLOWED_GRAPHQL_ORIGINS="*"
export ALLOWED_HOSTS=".localhost,127.0.0.1,.mydomain.com"
export CREATE_IMAGES_ON_DEMAND="False"
export DEFAULT_COUNTRY="US"
export DEFAULT_CURRENCY="USD"
export SECRET_KEY="Some random text!"
### In production, UWSGI is required rather than this:
#python3.9 manage.py runserver
python3.9 -m pip install uwsgi
### HTTP is just for testing:
#uwsgi --http :8000 --ini saleor/wsgi/uwsgi.ini
### SOCKET is required for NGINX:
uwsgi --socket :8000 --ini saleor/wsgi/uwsgi.ini
并使用 NGINX 通过 uwsgi 协议（而不是 http 协议）将请求传递到后端 Django 服务器：
http {
# the upstream component nginx needs to connect to
# for Saleor API
upstream django_api {
server 127.0.0.1:8000;
}
server {
server_name api.mydomain.com;
charset utf-8;
# max upload size
client_max_body_size 75M;
# Django media
location /media {
alias /home/ec2-user/repos/fork/saleor/media;
}
location /static {
alias /home/ec2-user/repos/fork/saleor/static;
}
# Finally, send all non-media requests to the Django server.
location / {
uwsgi_pass django_api;
include /home/ec2-user/repos/fork/saleor/uwsgi_params;
}
location /graphql {
uwsgi_pass django_api;
include /home/ec2-user/repos/fork/saleor/uwsgi_params;
}
#location / {
# proxy_pass http://127.0.0.1:8000/;
#}
#location /graphql {
# proxy_pass http://127.0.0.1:8000/graphql/;
#}
}
