Description

When Gitea is not installed in its own domain (eg. git.example.com), but is prefixed instead (eg. example.com/git), the Swagger UI is unable to make exemplary curl requests.

URLs to swagger.v1.json itself are valid - explore field has https://example.com/git/swagger.v1.json value and the same address is under [ Base URL: /api/v1 ] line.

Nevertheless, Swagger UI tries to make requests to https://example.com/api/v1/ endpoint, ignoring the /git prefix. This results with 404.

Maybe swagger.v1.json could be changed to template containing line

"basePath": "{{AppSubUrl}}/api/v1",

instead of

"basePath": "/api/v1",

so AppSubURL is not ignored, or something?

If gitea is not installed, any URL except /install must not be visit, or it's a bug.

It happens after installation, when Gitea is deployed with path prefix (AppSubURL), eg. gitea.io/try instead of try.gitea.io, so when you click on Explore on main page, it redirects you to gitea.io/try/explore/repos.
