Accessing Uploaded Attachments and Images Return HTTP 302 with Location /403

[chenhongbao]

Describe the bug

Add images and attachment to a post successfully, no error shows up, and then reopen the post, but image isn't displayed and attachement can't be downloaded.

I inspect the network activities. Refreshing the post with the image sends HTTP GET, but receives HTTP 302 response with location /403.

Clicking the attachment sends the HTTP GET, but receives HTTP 302 response with location /403.

To Reproduce

Steps to reproduce the behavior:

1. Unpack binary distribution from github, to directory ~/apache-answer-1.4.5-bin-linux-amd64, where there is the executable.
2. Follow the guide on the official site.
3. Run the command and set up database, email and admin.

ubuntu@VM-0-8-ubuntu:~/apache-answer-1.4.5-bin-linux-amd64$ sudo ./answer init -C ./answer-data/

4. Run the command to bring up the forum.

ubuntu@VM-0-8-ubuntu:~/apache-answer-1.4.5-bin-linux-amd64$ sudo nohup ./answer run -C ./answer-data/

5. Login, create a new question, post an image or upload an attachment.
6. Go back to landing page and reopen the previous post to examine the image and attachement, can't be shown or downloaded.
7. Inspect the network activities with dev tool and locate the URL:

http://plusai.site/uploads/files/post/5smfTQVm1EU/test.pdf
http://plusai.site/uploads/post/5smt4sbUZA9.png

8. On server, navigate to the data directory, which is

~/apache-answer-1.4.5-bin-linux-amd64/answer-data

The path to previous uploaded files are

~/apache-answer-1.4.5-bin-linux-amd64/answer-data/uploads/files/post/5smfTQVm1EU.pdf
~/apache-answer-1.4.5-bin-linux-amd64/answer-data/uploads/post/5smt4sbUZA9.png

9. confi.yaml after initialization is like
   ui: base_url: "" api_base_url: ""

There is no public_url arttribute.

Expected behavior

Image is displayed, and attachment can be downloaded by clicking the link.

@chenhongbao Is the following the cause of the problem?

• picture not diplay normally #667
• Getting HTTP 302 -> /403 on displaying uploaded images after answer "update" #722

[chenhongbao]

@LinkinStars Yes, they are similar issues. However, I also tried uploading attachment, saying pdf file, can it couldn't be accessed, neither. I kept logged in during the process, so /403 was not for my log in/out status.

So I conclude that Apache Answer doesn't support the direct access to the static resources on server.

Is my guess right? Or how can it be fixed?

@chenhongbao I need to check the issue with your config.

1. If you have login required turned off, please reply directly.
2. If you have login required set to on, you must use the domain to access your site. If you use IP, you will not be able to access your files, whether you are logged in or not. Images in the private mode can still be accessed when not logged in #502
3. If you have set login required to on and are using a domain to access your site and still can't access your files, please try clearing your cache, and if you still can't access them, please continue to comment below. picture not diplay normally #667 (comment)
