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 using Tesla.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

Examples:

ExampleApi.request(method: :get, url: "/users/path")

You can also use shortcut methods like:

ExampleApi.get("/users/1")
