正如这里所建议的，我正在本地机器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

仪表板可在线获取。但是，当我使用有效的用户/密码登录时，Saleor API 会抛出这些错误，通过以下方式可见sudo journalctl -xe：

可能是什么原因？我该如何调试它？谢谢！=)

笔记

当我在本地运行 API 和仪表板时，在localhostor上127.0.0.1，一切都很好。当我通过服务器运行 API 并在其上部署仪表板时，会引发上述错误。

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 配置应该是不同的。任何想法？

更新：测试 NGINX

之前我在本地运行 Saleor API 和 Saleor storefront 时，没有报错。

但是我做了一个测试。我什至使用 NGINX 进行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：

控制台错误

结论

看起来NGINX是问题的原因。

通过按模块启动后端 Django 服务器解决了问题uwsgi：

  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一个）将请求传递给后端 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/;
        #}


    }

}
