authorization_header(options)

Same as authorization_header/2 but defaults initial headers to include @user_agent.

authorization_header(arg1, headers)

Specs

authorization_header(Tentacat.Client.auth, list) :: list

There are two ways to authenticate through GitHub API v3:

  • Basic authentication
  • OAuth2 Token

This function accepts both.

Examples

iex> Tentacat.authorization_header(%{user: "user", password: "password"}, [])
[{"Authorization", "Basic dXNlcjpwYXNzd29yZA=="}]

iex> Tentacat.authorization_header(%{access_token: "92873971893"}, [])
[{"Authorization", "token 92873971893"}]

delete(url, headers \\ [], options \\ [])

Specs

delete(binary, headers, Keyword.t) ::
  {:ok, HTTPoison.Response.t | HTTPoison.AsyncResponse.t} |
  {:error, HTTPoison.Error.t}

Issues a DELETE request to the given url.

Returns {:ok, response} if the request is successful, {:error, reason} otherwise.

See request/5 for more detailed information.

Specs

delete!(binary, headers, Keyword.t) ::
  HTTPoison.Response.t |

get(url, headers \\ [], options \\ [])

Specs

Issues a GET request to the given url.

get(path, client, params \\ [], options \\ [])

Underlying utility retrieval function. The options passed affect both the return value and, ultimately, the number of requests made to GitHub.

Options:

  • :pagination - Can be :none, :manual, :stream, or :auto. Defaults to :auto :none will only return the first page. You won’t have access to the headers to manually paginate. :auto will block until all the pages have been retrieved and concatenated together. Most of the time, this is what you want. For example, Tentacat.Repositories.list_users("chrismccord") and Tentacat.Repositories.list_users("octocat") have the same interface though one call will page many times and the other not at all. :stream will return a Stream, prepopulated with the first page. :manual will return a 3 element tuple of {page_body, url_for_next_page, auth_credentials}, which will allow you to control the paging yourself.

Issues an HTTP request with the given method to the given url.

This function is usually used indirectly by get/3, post/4, put/4, etc

Args:

  • method - HTTP method as an atom (:get, :head, :post, :put, :delete, etc.)
  • url - target url as a binary string or char list
  • body - request body. See more below
  • headers - HTTP headers as an orddict (e.g., [{"Accept", "application/json"}])
  • options - Keyword list of options

Body:

  • binary, char list or an iolist
  • {:form, [{K, V}, ...]} - send a form url encoded
  • {:file, "/path/to/file"} - send a file

Options:

  • :timeout - timeout to establish a connection, in milliseconds. Default is 8000
  • :recv_timeout - timeout used when receiving a connection. Default is 5000
  • :stream_to - a PID to stream the response to
  • :proxy - a proxy to be used for the request; it can by a regular url or a {Host, Proxy} tuple
  • :proxy_auth - proxy authentication {User, Password} tuple
  • :ssl - SSL options supported by the ssl erlang module
  • :follow_redirect - a boolean that causes redirects to be followed
  • :max_redirect - an integer denoting the maximum number of redirects to follow

Timeouts can be an integer or :infinity

This function returns {:ok, response} or {:ok, async_response} if the request is successful, {:error, reason} otherwise.

Examples

request(:post, "https://my.website.com", "{\"foo\": 3}", [{"Accept", "application/json"}])

Specs

request!(atom, binary, binary, headers, Keyword.t) :: HTTPoison.Response.t

Issues an HTTP request with the given method to the given url, raising an exception in case of failure.

request!/5 works exactly like request/5 but it returns just the response in case of a successful request, raising an exception in case the request fails.
