#delete(argument) ⇒ Hash

Delete an existing resource

Examples:

resp = @http.delete(Requests::Customer.remove_session)
assert resp.code == 204

Parameters:

  • argument (Hash, String) —

    hash containing at least key :path or a string with the path

Returns:

  • (Hash) —

    response
    Including at least the symbol keys:
    :data = the response data body.
    :message = plain text response.
    :code = code response (200=ok,500=wrong...).
    All keys in response are lowercase.
    data, message and code can also be accessed as attributes like .message .code .data.
    In case of fatal error returns { fatal_error: "the error description", code: nil, message: nil, data: '' }

#get(arg, save_data: '') ⇒ Hash

Get data from path

Examples:

resp = @http.get(Requests::Customer.get_profile)
assert resp.code == 200
resp = @http.get("/customers/1223")
assert resp.message == "OK"
resp = @http.get("/assets/images/logo.png", save_data: './tmp/')
resp = @http.get("/assets/images/logo.png", save_data: './tmp/example.png')

Parameters:

  • arg (Hash, String) —

    hash containing at least key :path or a string with the path

  • save_data (String) (defaults to: '') —

    the path or path and file name where we want to save the response data

Returns:

  • (Hash) —

    response.
    Including at least the symbol keys:
    :data = the response data body.
    :message = plain text response.
    :code = code response (200=ok,500=wrong...).
    All keys in response are lowercase.
    data, message and code can also be accessed as attributes like .message .code .data.

#head(argument) ⇒ Hash

Implementation of the http HEAD method.
Asks for the response identical to the one that would correspond to a GET request, but without the response body.
This is useful for retrieving meta-information written in response headers, without having to transport the entire content.

Parameters:

  • argument (Hash, String) —

    hash containing at least key :path or directly an string with the path

Returns:

  • (Hash) —

    response
    Including at least the symbol keys:
    :message = plain text response.
    :code = code response (200=ok,500=wrong...).
    All keys in response are lowercase.
    message and code can also be accessed as attributes like .message .code.
    In case of fatal error returns { fatal_error: "the error description", code: nil, message: nil }

#post(*arguments) ⇒ Hash

Post data to path

Examples:

resp = @http.post(Requests::Customer.update_customer)
assert resp.code == 201
resp = http.post( {
                    path: "/api/users",
                    data: {name: "morpheus", job: "leader"}
                   } )
pp resp.data.json

Parameters:

  • arguments (Hash) —

    containing at least keys :data and :path.
    In case :data not supplied and :data_examples array supplied, it will be taken the first example as :data.

  • arguments (Array<path, data, additional_headers>) —

    path (string).
    data (json data for example).
    additional_headers (Hash key=>value).

Returns:

  • (Hash) —

    response
    Including at least the symbol keys:
    :data = the response data body.
    :message = plain text response.
    :code = code response (200=ok,500=wrong...).
    All keys in response are lowercase.
    data, message and code can also be accessed as attributes like .message .code .data.
    In case of fatal error returns { fatal_error: "the error description", code: nil, message: nil, data: '' }

#send_request(request_hash) ⇒ Hash

It will send the request depending on the :method declared on the request hash
Take a look at https://github.com/MarioRuiz/Request-Hash

Examples:

resp = @http.send_request Requests::Customer.remove_session
assert resp.code == 204

Parameters:

  • request_hash (Hash) —

    containing at least key :path and :method. The methods that are accepted are: :get, :head, :post, :put, :delete, :patch

Returns:

  • (Hash) —

    response
    Including at least the symbol keys:
    :data = the response data body.
    :message = plain text response.
    :code = code response (200=ok,500=wrong...).
    All keys in response are lowercase.
    data, message and code can also be accessed as attributes like .message .code .data.
    In case of fatal error returns { fatal_error: "the error description", code: nil, message: nil, data: '' }
