request(client \\ %Tesla.Client{}, options)
Specs

Options
:method
- the request method, one of [:head, :get, :delete, :trace, :options, :post, :put, :patch]:url
- either full url e.g. "http://example.com/some/path" or just "/some/path" if usingTesla.Middleware.BaseUrl
:query
- a keyword list of query params, e.g.[page: 1, per_page: 100]
:headers
- a keyworld list of headers, e.g.[{"content-type", "text/plain"}]
:body
- depends on used middleware:- by default it can be a binary
- if using e.g. JSON encoding middleware it can be a nested map
- if adapter supports it it can be a Stream with any of the above
:opts
- custom, per-request middleware or adapter options
