I tried running this code from Ryan Bates's ruby cast but it doesn't work. I think it assumes the use of Savon 1.
require "savon"
client = Savon::Client.new("http://www.webservicex.net/uszip.asmx?WSDL")
response = client.request :web, :get_info_by_zip, body: { "USZip" => zip }
if response.success?
data = response.to_array(:get_info_by_zip_response, :get_info_by_zip_result, :new_data_set, :table).first
if data
#state = data[:state]
#city = data[:city]
#area_code = data[:area_code]
#time_zone = data[:time_zone]
puts #state
puts #city
puts #area_code
end
end
What is the correct implementation for Savon 2? I would like to copy and paste it and have it work.
Here is an excerpt from my Service-Wrapper class providing the SOAP-Services to other ruby objects. I initialize the client by providing the WSDL location and an own method for each SOAP operation. The thirdparty method is invoked with #client.call passing a block which creates a SOAP message with provided params.
class Client
include Singleton
def wsdl_method_to_call
begin
response = #client.call(:wsdl_method_to_call) do
message auth:CREDENTIALS, param_1: param_1_value, param_2: param_2_value
end
rescue
raise CustomServiceException.new("Error ... , response : #{response}")
end
end
def initialize()
#client = Savon::Client.new(wsdl: WSDL)
end
private
WSDL = "http://service_host/wsdl"
CREDENTIALS = "foo|bar"
end
so maybe you should try something like:
response = client.call(:get_info_by_zip) do
message USZip: zip
end

I am using the HTTParty gem to make a call to the GitHub API to access a list of user's repos.
It is a very simple application using Sinatra that displays a user's favourite programming language based on the most common language that appears in their repos.
I am a bit stuck on how I can write an RSpec expectation that mocks out the actual API call and instead just checks that json data is being returned.
I have a mock .json file but not sure how to use it in my test.
Any ideas?
github_api.rb
require 'httparty'
class GithubApi
attr_reader :username, :data, :languages
def initialize(username)
#username = username
#response = HTTParty.get("https://api.github.com/users/#{#username}/repos")
#data = JSON.parse(#response.body)
end
end
github_api_spec.rb
require './app/models/github_api'
require 'spec_helper'
describe GithubApi do
let(:github_api) { GithubApi.new('mock_user') }
it "receives a json response" do
end
end
Rest of the files for clarity:
results.rb
require 'httparty'
require_relative 'github_api'
class Results
def initialize(github_api = Github.new(username))
#github_api = github_api
#languages = []
end
def get_languages
#github_api.data.each do |repo|
#languages << repo["language"]
end
end
def favourite_language
get_languages
#languages.group_by(&:itself).values.max_by(&:size).first
end
end
application_controller.rb
require './config/environment'
require 'sinatra/base'
require './app/models/github_api'
class ApplicationController < Sinatra::Base
configure do
enable :sessions
set :session_secret, "#3x!ilt£"
set :views, 'app/views'
end
get "/" do
erb :index
end
post "/user" do
#github = GithubApi.new(params[:username])
#results = Results.new(#github)
#language = #results.favourite_language
session[:language] = #language
session[:username] = params[:username]
redirect '/results'
end
get "/results" do
#language = session[:language]
#username = session[:username]
erb :results
end
run! if app_file == $0
end
There are multiple ways you could approach this problem.
You could, as #anil suggested, use a library like webmock to mock the underlying HTTP call. You could also do something similar with VCR (https://github.com/vcr/vcr) which records the results of an actual call to the HTTP endpoint and plays back that response on subsequent requests.
But, given your question, I don't see why you couldn't just use an Rspec double. I'll show you how below. But, first, it would be a bit easier to test the code if it were not all in the constructor.
github_api.rb
require 'httparty'
class GithubApi
attr_reader :username
def initialize(username)
#username = username
end
def favorite_language
# method to calculate which language is used most by username
end
def languages
# method to grab languages from repos
end
def repos
repos ||= do
response = HTTParty.get("https://api.github.com/users/#{username}/repos")
JSON.parse(response.body)
end
end
end
Note that you do not need to reference the #username variable in the url because you have an attr_reader.
github_api_spec.rb
require './app/models/github_api'
require 'spec_helper'
describe GithubApi do
subject(:api) { described_class.new(username) }
let(:username) { 'username' }
describe '#repos' do
let(:github_url) { "https://api.github.com/users/#{username}/repos" }
let(:github_response) { instance_double(HTTParty::Response, body: github_response_body) }
let(:github_response_body) { 'response_body' }
before do
allow(HTTParty).to receive(:get).and_return(github_response)
allow(JSON).to receive(:parse)
api.repos
end
it 'fetches the repos from Github api' do
expect(HTTParty).to have_received(:get).with(github_url)
end
it 'parses the Github response' do
expect(JSON).to have_received(:parse).with(github_response_body)
end
end
end
Note that there is no need to actually load or parse any real JSON. What we're testing here is that we made the correct HTTP call and that we called JSON.parse on the response. Once you start testing the languages method you'd need to actually load and parse your test file, like this:
let(:parsed_response) { JSON.parse(File.read('path/to/test/file.json')) }
You can mock those API calls using https://github.com/bblimke/webmock and send back mock.json using webmock. This post, https://robots.thoughtbot.com/how-to-stub-external-services-in-tests walks you through the setup of webmock with RSpec (the tests in the post mock GitHub API call too)
I will go ahead and apologize upfront as I am new to ruby and rails and I cannot for the life of me figure out how to implement using hashids in my project. The project is a simple image host. I have it already working using Base58 to encode the sql ID and then decode it in the controller. However I wanted to make the URLs more random hence switching to hashids.
I have placed the hashids.rb file in my lib directory from here: https://github.com/peterhellberg/hashids.rb
Now some of the confusion starts here. Do I need to initialize hashids on every page that uses hashids.encode and hashids.decode via
hashids = Hashids.new("mysalt")
I found this post (http://zogovic.com/post/75234760043/youtube-like-ids-for-your-activerecord-models) which leads me to believe I can put it into an initializer however after doing that I am still getting NameError (undefined local variable or method `hashids' for ImageManager:Class)
so in my ImageManager.rb class I have
require 'hashids'
class ImageManager
class << self
def save_image(imgpath, name)
mime = %x(/usr/bin/exiftool -MIMEType #{imgpath})[34..-1].rstrip
if mime.nil? || !VALID_MIME.include?(mime)
return { status: 'failure', message: "#{name} uses an invalid format." }
end
hash = Digest::MD5.file(imgpath).hexdigest
image = Image.find_by_imghash(hash)
if image.nil?
image = Image.new
image.mimetype = mime
image.imghash = hash
unless image.save!
return { status: 'failure', message: "Failed to save #{name}." }
end
unless File.directory?(Rails.root.join('uploads'))
Dir.mkdir(Rails.root.join('uploads'))
end
#File.open(Rails.root.join('uploads', "#{Base58.encode(image.id)}.png"), 'wb') { |f| f.write(File.open(imgpath, 'rb').read) }
File.open(Rails.root.join('uploads', "#{hashids.encode(image.id)}.png"), 'wb') { |f| f.write(File.open(imgpath, 'rb').read) }
end
link = ImageLink.new
link.image = image
link.save
#return { status: 'success', message: Base58.encode(link.id) }
return { status: 'success', message: hashids.encode(link.id) }
end
private
VALID_MIME = %w(image/png image/jpeg image/gif)
end
end
And in my controller I have:
require 'hashids'
class MainController < ApplicationController
MAX_FILE_SIZE = 10 * 1024 * 1024
MAX_CACHE_SIZE = 128 * 1024 * 1024
#links = Hash.new
#files = Hash.new
#tstamps = Hash.new
#sizes = Hash.new
#cache_size = 0
class << self
attr_accessor :links
attr_accessor :files
attr_accessor :tstamps
attr_accessor :sizes
attr_accessor :cache_size
attr_accessor :hashids
end
def index
end
def transparency
end
def image
##imglist = params[:id].split(',').map{ |id| ImageLink.find(Base58.decode(id)) }
#imglist = params[:id].split(',').map{ |id| ImageLink.find(hashids.decode(id)) }
end
def image_direct
#linkid = Base58.decode(params[:id])
linkid = hashids.decode(params[:id])
file =
if Rails.env.production?
puts "#{Base58.encode(ImageLink.find(linkid).image.id)}.png"
File.open(Rails.root.join('uploads', "#{Base58.encode(ImageLink.find(linkid).image.id)}.png"), 'rb') { |f| f.read }
else
puts "#{hashids.encode(ImageLink.find(linkid).image.id)}.png"
File.open(Rails.root.join('uploads', "#{hashids.encode(ImageLink.find(linkid).image.id)}.png"), 'rb') { |f| f.read }
end
send_data(file, type: ImageLink.find(linkid).image.mimetype, disposition: 'inline')
end
def upload
imgparam = params[:image]
if imgparam.is_a?(String)
name = File.basename(imgparam)
imgpath = save_to_tempfile(imgparam).path
else
name = imgparam.original_filename
imgpath = imgparam.tempfile.path
end
File.chmod(0666, imgpath)
%x(/usr/bin/exiftool -all= -overwrite_original #{imgpath})
logger.debug %x(which exiftool)
render json: ImageManager.save_image(imgpath, name)
end
private
def save_to_tempfile(url)
uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = uri.scheme == 'https'
http.start do
resp = http.get(uri.path)
file = Tempfile.new('urlupload', Dir.tmpdir, :encoding => 'ascii-8bit')
file.write(resp.body)
file.flush
return file
end
end
end
Then in my image.html.erb view I have this:
<%
#imglist.each_with_index { |link, i|
id = hashids.encode(link.id)
ext = link.image.mimetype.split('/')[1]
if ext == 'jpeg'
ext = 'jpg'
end
puts id + '.' + ext
%>
Now if I add
hashids = Hashids.new("mysalt")
in ImageManager.rb main_controller.rb and in my image.html.erb I am getting this error:
ActionView::Template::Error (undefined method `id' for #<Array:0x000000062f69c0>)
So all in all implementing hashids.encode/decode is not as easy as implementing Base58.encode/decode and I am confused on how to get it working... Any help would be greatly appreciated.
I would suggest loading it as a gem by including it into your Gemfile and running bundle install. It will save you the hassle of requiring it in every file and allow you to manage updates using Bundler.
Yes, you do need to initialize it wherever it is going to be used with the same salt. Would suggest that you define the salt as a constant, perhaps in application.rb.
The link you provided injects hashids into ActiveRecord, which means it will not work anywhere else. I would not recommend the same approach as it will require a high level of familiarity with Rails.
You might want to spend some time understanding ActiveRecord and ActiveModel. Will save you a lot of reinventing the wheel. :)
Before everythink you should just to test if Hashlib is included in your project, you can run command rails c in your project folder and make just a small test :
>> my_id = ImageLink.last.id
>> puts Hashids.new(my_id)
If not working, add the gem in gemfile (that anyway make a lot more sence).
Then, I think you should add a getter for your hash_id in your ImageLink model.
Even you don't want to save your hash in the database, this hash have it's pllace in your model. See virtual property for more info.
Remember "Skinny Controller, Fat Model".
class ImageLink < ActiveRecord::Base
def hash_id()
# cache the hash
#hash_id ||= Hashids.new(id)
end
def extension()
# you could add the logic of extension here also.
ext = image.mimetype.split('/')[1]
if ext == 'jpeg'
'jpg'
else
ext
end
end
end
Change the return in your ImageManager#save_image
link = ImageLink.new
link.image = image
# Be sure your image have been saved (validation errors, etc.)
if link.save
{ status: 'success', message: link.hash_id }
else
{status: 'failure', message: link.errors.join(", ")}
end
In your template
<%
#imglist.each_with_index do |link, i|
puts link.hash_id + '.' + link.extension
end # <- I prefer the do..end to not forgot the ending parenthesis
%>
All this code is not tested...
I was looking for something similar where I can disguise the ids of my records. I came across act_as_hashids.
https://github.com/dtaniwaki/acts_as_hashids
This little gem integrates seamlessly. You can still find your records through the ids. Or with the hash. On nested records you can use the method with_hashids.
To get the hash you use to_param on the object itself which result in a string similar to this ePQgabdg.
Since I just implemented this I can't tell how useful this gem will be. So far I just had to adjust my code a little bit.
I also gave the records a virtual attribute hashid so I can access it easily.
attr_accessor :hashid
after_find :set_hashid
private
def set_hashid
self.hashid = self.to_param
end
I'm learning how to work with HTTParty and API and I'm having an issue with my code.
Users/admin/.rbenv/versions/2.0.0-p481/lib/ruby/2.0.0/uri/generic.rb:214:in `initialize': the scheme http does not accept registry part: :80 (or bad hostname?)
I've tried using debug_output STDOUT both as an argument to my method and after including HTTParty to have a clue but with no success. Nothing gets displayed:
require 'httparty'
class LolObserver
include HTTParty
default_timeout(1) #timeout after 1 second
attr_reader :api_key, :playerid
attr_accessor :region
def initialize(region,playerid,apikey)
#region = region_server(region)
#playerid = playerid
#api_key = apikey
end
def region_server(region)
case region
when "euw"
self.class.base_uri "https://euw.api.pvp.net"
self.region = "EUW1"
when "na"
self.class.base_uri "https://na.api.pvp.net"
self.region = "NA1"
end
end
def handle_timeouts
begin
yield
#Timeout::Error, is raised if a chunk of the response cannot be read within the read_timeout.
#Timeout::Error, is raised if a connection cannot be created within the open_timeout.
rescue Net::OpenTimeout, Net::ReadTimeout
#todo
end
end
def base_path
"/observer-mode/rest/consumer/getSpectatorGameInfo"
end
def current_game_info
handle_timeouts do
url = "#{ base_path }/#{region}/#{playerid}?api_key=#{api_key}"
puts '------------------------------'
puts url
HTTParty.get(url,:debug_output => $stdout)
end
end
end
I verified my URL which is fine so I'm lost as to where the problem is coming from.
I tested with a static base_uri and it doesn't change anything.
The odd thing is when I do:
HTTParty.get("https://euw.api.pvp.net/observer-mode/rest/consumer/getSpectatorGameInfo/EUW1/randomid?api_key=myapikey")
Everything is working fine and I'm getting a response.
HTTParty doesn't seem to like the way you set your base_uri.
Unless you need it to be like that just add another attr_reader called domain and it will work.
require 'httparty'
class LolObserver
include HTTParty
default_timeout(1) #timeout after 1 second
attr_reader :api_key, :playerid, :domain
attr_accessor :region
def initialize(region,playerid,apikey)
#region = region_server(region)
#playerid = playerid
#api_key = apikey
end
def region_server(region)
case region
when "euw"
#domain = "https://euw.api.pvp.net"
self.region = "EUW1"
when "na"
#domain = "https://na.api.pvp.net"
self.region = "NA1"
end
end
def handle_timeouts
begin
yield
#Timeout::Error, is raised if a chunk of the response cannot be read within the read_timeout.
#Timeout::Error, is raised if a connection cannot be created within the open_timeout.
rescue Net::OpenTimeout, Net::ReadTimeout
#todo
end
end
def base_path
"/observer-mode/rest/consumer/getSpectatorGameInfo"
end
def current_game_info
handle_timeouts do
url = "#{domain}/#{ base_path }/#{region}/#{playerid}?api_key=#{api_key}"
puts '------------------------------'
puts url
HTTParty.get(url,:debug_output => $stdout)
end
end
end
I'm fairly new to Ruby. I'm trying to write a RSpec test against the following class:
require 'rest-client'
class Query
def initialize
##log = Logger.new(STDOUT)
RestClient.log = ##log
##user = "joe#example.com"
##password = "joe123"
end
def get_details
begin
url = "http://api.example.com/sample/12345"
resource = RestClient::Resource.new(url, :user => ##user,
:password => ##password, :content_type => :json, :accept => :json)
details = resource.get
rescue => e
throw e # TODO: something more intelligent
end
end
end
I've discovered that unlike RestClient.get which returns a Response, Resource.get returns the body of the response as a String. I'd like to get Response working, because I will want to expand this to make different sub-resource calls.
Is there a way that I can find out the HTTP status code of the GET call response? That would allow me to write a test like:
require 'rspec'
require_relative 'query'
describe "Query site" do
before :all do
#query = Query.new
end
it "should connect to site" do
details = #query.get_details
expect(details).to_not be_nil
expect(details.code).to eq(200)
expect(details.body).to match /description12345/
end
end
Get returns an instance of the class RestClient::Response that inherits from the String class.
You can still check the return code by calling the method code details.code. Other methods are for example details.headers and details.cookies
I'd like to stream data from an HTTP GET request to an HTTP POST or PUT request. I'd prefer to use Ruby and have already made an attempt using EventMachine and EM-HTTP-Request.
Here's my attempt, to be called using:
HttpToS3Stream.new(src_url, dest_bucket, dest_key, aws_access_key_id, aws_secret_access_key)

#put_stream = S3PutStream.new(#s3_bucket, #s3_key, #s3_access_key_id, #s3_secret_access_key, #get_stream.content_length)
# set listener on get stream, starts request, pipes data to put stream
#get_stream.listener = #put_stream
}
end
end

end
end
HttpToS3Stream.new(src_url, dest_bucket, dest_key, aws_access_key_id, aws_secret_access_key)
It seems to be working but always stops at 33468 bytes. Not sure what that's about. Now, by passing chunks directly to #listener.send_data, it is processing the entire GET body. However, the upload is not occurring successfully.
How can I get this to work? And is there a name for what I'm trying to do? I'm having trouble searching for more information.
Any help is appreciated.
