René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Absolute URLs without port","articleBody":"So I used this to build a dockerized API with Django Rest Framework. Since I develop several projects at once, I use a different port for local development. Turns out that Django or at least Django Rest Framework was not able to produce the right absolute URLs in the browsable API. Instead of `localhost:12345/api`, I only got `localhost/api`.\r\n\r\nWhat I tried:\r\n- setting `USE_X_FORWARDED_FOR_HOST` and `USE_X_FORWARDED_FOR_PORT` to True, see https://docs.djangoproject.com/en/3.0/ref/settings/#use-x-forwarded-host\r\n\r\nAnyway, what fixed it for me was using `$http_host` instead of `$host` in the nginx config.\r\n```\r\nserver {\r\n    listen 80;\r\n    # server_name localhost;\r\n    charset utf-8;\r\n\r\n    location /static {\r\n        alias /usr/share/nginx/static;\r\n    }\r\n\r\n    location / {\r\n        proxy_pass http://web:8000;\r\n        proxy_set_header Host $http_host;  # $host is without port, $http_host works\r\n        proxy_set_header X-Real-IP $remote_addr;\r\n        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;\r\n    }\r\n\r\n}\r\n```\r\n\r\nMy issue: https://github.com/lorey/socials-api/issues/4\r\nMy configuration: https://github.com/lorey/socials-api/tree/d7f0bca4df5be9c662ede96aac6ae89d17890404\r\n\r\nHope this helps anyone. Let me know if someone finds a better solution or can explain this.","author":{"url":"https://github.com/lorey","@type":"Person","name":"lorey"},"datePublished":"2020-05-06T10:22:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/66/dockerizing-django/issues/66"}
