Support specifying properties on media type

[technicalpickles]

In addition to the custom media type to specify API version, some methods support a (raw, full, etc): https://developer.github.com/v3/media/

It'd be useful to be able to specify these per-request. I'm not sure how the best way to do that would be, as currently, you can pass in data to get, but it's treated as a query string.

A workaround for now is to make a new github instance with a custom apiVersion like:

      github = require('githubot')(robot, apiVersion: 'v3.raw')

You'd have to make other instances if you wanted a different property though.

Actually, that workaround doesn't work because it tries to JSON.parse the result, and it's just plain text coming back.

Indeed - I actually recently added a way to specify per-request options:

gh.withOptions(apiVersion: 'v3.raw').get "/foo"

But if we need to treat the response data as something other than JSON, we'd need a new option anyhow. I'm curious, do you have a specific use case in mind for this?

[technicalpickles]

Yep, the Contents API https://developer.github.com/v3/repos/contents/ . At the very least, I think if the apiVersion matches /raw/ probably should not JSON.parse.

I can think of two ways to handle this:

1. Check apiVersion against a regexp and if it matches certain things, treat the responses different. If we went with this version, we'd need to differentiate between apiVersion: 'v3.raw' and apiVersion: 'v3.raw+json', and I think that would end up a little weird since we're in the habit of automatically adding the +json for people.
2. Offer a new option, like raw: true or mediaType: 'raw', that would both modify the header and parse the response appropriately. I'm leaning towards this one because it makes it a little more obvious.

I think being able to specify the entire media type would be most flexible. Then, don't try to parse the response unless it has json in it. Thoughts?

Yeah, I was debating that too and came to the same tentative conclusion. We can have a mediaType option with default value of "+json". Then someone can set it to "raw" for raw files, or "raw+json" or whatever for weird cases. Githubot will combine it with the apiVersion and add a dot when necessary, and can just match against /\+json$/ and parse only those responses.
