Create a Github Token Using Elixir HTTPoison Library

Question

I want to create a Github token in Elixir using the HTTPoison library, but I just can't figure out how to send the HTTPoison parameter.

When using curl it will be something like this

 $ curl -i -u "ColdFreak" -H "X-GitHub-OTP: 123456" -d '{"scopes": ["repo", "user"], "note" : "getting-started"}' https://api.github.com/authorizations 

when I use the HTTPoison library, I just can't figure out how to publish it.

 url = "https://api.github.com/authorizations" HTTPoison.post!(url, [scopes: ["repo", "user"], note: "getting-started"], %{"X-GitHub-OTP" => "12345"}) 

then he gave an error something like this

 ** (ArgumentError) argument error :erlang.iolist_to_binary([{"scopes", ["repo", "user"]}, {"note", "getting-started"}]) (hackney) src/hackney_client/hackney_request.erl:338: :hackney_request.handle_body/4 (hackney) src/hackney_client/hackney_request.erl:79: :hackney_request.perform/2 

Can someone tell me how to do it right.

Answer 1

The problem is with your body. HTTPoison expects either a binary or a tuple in the format {:form, [foo: "bar"]} :

 HTTPoison.post!(url, {:form, [scopes: "repo, user", note: "getting-started"]}, %{"X-GitHub-OTP" => "610554"}) 

or

 HTTPoison.post!(url, "{\"scopes\": \"repo, user\", \"note\": \"getting-started\"}", %{"X-GitHub-OTP" => "610554"}) 

You can use the Poison library to generate the JSON above:

 json = %{scopes: "repo, user", note: "getting-started"} |> Poison.encode! HTTPoison.post!(url, json, %{"X-GitHub-OTP" => "610554"})
