Set up TLS proxy for Google Cloud Endpoint APIs

Question

I have been viewing my Google App Engine endpoint APIs in the API explorer (localhost) without issues, now am getting this:

in full it says:

You are exploring an API that is described or served via HTTP instead of HTTPS. This is insecure and may be blocked by your browser. To fix this, set up a TLS proxy for your API. Alternatively, you can tell your browser to allow active content via HTTP at this site (on Chrome, click the shield in the URL bar), but this will not improve security or dismiss this message.

This is one of the API methods I have in my endpoint:

@ApiMethod(
        name = "insert",
        path = "movie",
        httpMethod = ApiMethod.HttpMethod.POST)
public Movie insert(Movie movie) throws UnauthorizedException {
    ...
}

Since I do not know what's causing this all of a sudden, I do not know what else to show.I've tried updating my browsers (Firefox, Opera, Chrome) with no luck.

Answer 1

The same problem appeared to me today

For now if you are using chrome you can click on the shield icon on the right of the URL bar and click on something saying load scripts anyway and your API should appear.

Answer 2

You will likely want to use a browser-based workaround, such as the shield icon on Chrome. This was recently added to address a security vulnerability. Unfortunately, we are unable to do better than this. A colleague suggests that stunnel may be viable for setting up a TLS proxy, if you want to go that route.
