【问题描述】：

我正在尝试设置我的 Django Rest Framework 应用程序。不幸的是，我仍然无法正确获取媒体文件的 url。

我尝试将此答案中的行添加到我的 nginx 配置中，结果是“错误请求 (400)”：Django Rest framework swagger base url

应用程序正在 my-domain.com 上运行。

https://my-domain.com/user/

{
    "count": 1,
    "next": null,
    "previous": null,
    "results": [
        {
            "id": "512e0f9f-f08a-4a2d-8e1d-b933a16c0a1f",
            "date_joined": "2021-10-10T11:41:05.077828Z",
            "name": "Maxine Mustermann",
            "user_picture": "**http://127.0.0.1:8337**/mediafiles/images/usr1.jpeg"
        }
    ]
}

预期：https://my-domain.com/mediafiles/images/usr1.jpeg（虽然图片可以通过这个url访问）

返回：http://127.0.0.1:8337/mediafiles/images/usr1.jpeg

docker-compose 文件：

version: "3.8"

services:
  db:
    image: postgres:13-alpine
    volumes:
      - postgres_data_staging:/var/lib/postgresql/data/
    env_file:

    env_file:

    depends_on:
      - db

  nginx:
    build: ./nginx

nginx.conf：

upstream ae_backend {
    server web:8000;
}

server {
    listen 80;
    client_max_body_size 75M;
    server_name $DOMAIN www.$DOMAIN;

    location / {
        proxy_pass http://ae_backend;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
    }

    location /staticfiles/ {
        alias /home/api/web/staticfiles/;
    }

    location /mediafiles/ {
        alias /home/api/web/mediafiles/;
    }
}

服务器配置nginx/sites-enabled/my-api:

server {

    server_name my-domain.com;
    location = /favicon.ico { access_log off; log_not_found off; }
    # add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
    add_header 'Access-Control-Allow-Headers' 'Authorization';

    location / {
        proxy_pass http://127.0.0.1:8337;
    }

    listen [::]:443 ssl; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/my-domain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/my-domain.com/privkey.pem; # managed by Certbot

    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = my-domain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80;
    listen [::]:80;

    server_name my-domain.com;
    return 404; # managed by Certbot

    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
    add_header 'Access-Control-Allow-Headers' 'Authorization';
}

任何帮助和参考将不胜感激。

谢谢！！

【解决方案1】：

我将此部分编辑到我的服务器 nginx 配置中：

location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://127.0.0.1:8337;
    }

并确保 my-domain.com 列在“ALLOWED_HOSTS”(settings.py) 中。
