Serving the Swagger UI over HTTPS fails

[lysnikolaou]

Hey hey,

thanks for the awesome work you've been doing 🚀. We have encountered an error, that we think is related to how drf-spectacular serves the schema as HTML.

Describe the bug
Trying to access the Swagger UI on our staging system, which can only be accessed through HTTPS, fails with

Errors
 
Fetch errorFailed to fetch http://<URL>/schema
Fetch errorPossible mixed-content issue? The page was loaded over https:// but a http:// URL was specified. Check that you are not attempting to load mixed content.

Expected behavior
We'd expect that we could deploy our docs and serve it over HTTPS without problems.

hey! this was likely introduced due to #173 . i will have a look later today.

@lysnikolaou can you confirm that this works for you? pretty sure it should. would do a minor release afterwards

[lysnikolaou]

Hey @tfranzel, thanks for the quick response! Unfortunately, pip installing the master branch from this repo does not resolve the issue.

[tfranzel]

thanks for checking it out so quickly. i'm a bit puzzled here. i made all rendered urls relative so no http/s mixing should be going on for swagger ui. are you certain your install has the most-recent master?

pip install git+git://github.com/tfranzel/drf-spectacular.git@26273bb9ae33c6865bd0df9fa07ad19daa45175a

to be sure but pip install -U ....@master should be the same (+1 unrelated commit).

Yup, it must have been some wrong configuration on my part. Upgrading to 0.11.1 fixes this. Thanks a bunch for the quick fix.
