In ruby built-in library Net::HTTP it's possible. In the code of Faraday there's no mention of MKCOL anywhere.
How to send MKCOL in Faraday?
There seems to be a filter on the allowed http methods:
https://github.com/lostisland/faraday/blob/v0.15.3/lib/faraday/connection.rb#L15
You can make a call by doing:
Faraday::Connection::METHODS << :mkcol
f = Faraday.new('http://localhost:3000')
f.run_request(:mkcol, '/mypath', { 'param-foo' => 'test' }, { 'X-fake-header' => 'test' })

I want to use the Microsoft Translate API and I am already stuck obtaining the access token.
This is how my code looks like:
authUri = "https://datamarket.accesscontrol.windows.net/v2/OAuth2-13/"
paramHash = {
"client_id" => "test",
"client_secret" => "*****",
"scope" => "http://api.microsofttranslator.com",
"grant_type" => "client_credentials"
}
postData = Net::HTTP.post_form(URI.parse(authUri), paramHash)
puts postData.body
But this won't terminate and after a while I get a Timeout Error:
`rescue in rbuf_fill': Timeout::Error (Timeout::Error)
I already tried the a Rest-Client gem and curl. Both worked perfectly fine, but I don't like incorporating another gem for such a simple task.
When I send the post request to localhost and listen with netcat I see the exact same requests (except for User-Agent, but even changing that didn't solve the problem)
I'm setting up an application which can make LastFM API Requests.
These are simple get requests and I'm using the HTTParty gem.
My function is as follows:
def get_albums
self.class.base_uri "http://ws.audioscrobbler.com/2.0/"
options = {
:user => "Gerard1992",
:method => "user.gettopalbums",
:api_key => Constants::LASTFM_API_KEY,
:format => "json"
}
puts options.to_query
self.class.get "/?#{options.to_query}", {} #options don't work
end
This piece of code that's shown above works. The get request returns a set of JSON. My problem is that this /?#{options.to_query} doesn't look that neat. And neither does the actual (now empty {}) options parameter. How do I get the HTTParty options parameter to work like it should?
This is what I've tried, but both cases failed:
self.class.get "/", options
self.class.get "/", options => options
I appreciate the help.
The correct option for query parameters in HTTParty is :query, so what you want is:
self.class.get "/", query: options
You can see all the available parameters in the docs.
Send :verify => false in options hash
I've been trying to figure this out all day, and it's driving me crazy.
I have two rails apps, ServerApp and ClientApp. ClientApp gets data from ServerApp through an API, using the Her gem. Everything was great until I needed pagination information.
This is the method I am using to get the orders (this uses kamainari for pagination and ransack for search):
# ServerApp
def search
#search = Order.includes(:documents, :client).order('id desc').search(params[:q])
#orders = #search.result(distinct: true).page(params[:page]).per(params[:per])
respond_with #orders.as_json(include: :documents)
end
It returns an array of hashes in json, which Her uses as a collection of orders. That works fine.
# Response
[
{
"client_id": 239,
"created_at": "2013-05-15T15:37:03-07:00",
"id": 2422,
"ordered_at": "2013-05-15T15:37:03-07:00",
"origin": "online",
"updated_at": "2013-05-15T15:37:03-07:00",
"documents": [
{ ... }
]
},
...
]
But I needed pagination information. It looked like I needed to send it as metadata with my json. So I change my response to this:
respond_to do |format|
format.json do
render json: { orders: #orders.as_json(include: :documents), metadata: 'sent' }
end
end
This does indeed send over metadata, so in my ClientApp I can write #orders.metadata and get 'sent'. But now my orders are nested in an array inside of 'orders', so I need to use #orders.orders, and then it treats it like an array instead of a Her collection.
After doing some reading, it seemed sending pagination info through headers was the way a lot of other people did this (I was able to get the headers set up in an after_filter using this guide). But I am even more lost on how to get those response headers in my ClientApp - I believe I need a Faraday Middleware but I just am having no luck getting this to work.
If anyone knows how I can just get this done, I would be very grateful. I can't take another day of banging my head against the wall on this, but I feel like I am just one vital piece of info away from solving this!
I encountered the same issue and solved it by adding my own middleware and rewriting the "parse" and "on_complete" methods without that much hassle and avoiding the use of global variables.
Here's the code:
class CustomParserMiddleware < Her::Middleware::DefaultParseJSON
def parse(env)
json = parse_json(env[:body])
pagination = parse_json(env[:response_headers][:pagination_key]) || {}
errors = json.delete(:errors) || {}
metadata = json.delete(:metadata) || {}
{
:data => json,
:errors => errors,
:metadata => {
:pagination => pagination,
:additional_metadata => metadata
},
end
def on_complete(env)
env[:body] = case env[:status]
when 204
parse('{}')
else
parse(env)
end
end
end
then, you can access the pagination as follows:
model = Model.all
model.metadata[:pagination]
I finally got this working. The trick was to use a global variable in the faraday on_complete - I tried to find a better solution but this was the best I could do. Once again, I got the header code from here. Here's the full guide to how to get pagination working with Her:
First, on my server side, I have the Kaminari gem, and I pass page and per as params to the server from the client. (This is also using ransack for searching)
def search
#search = Order.order('id desc').search(params[:q])
#orders = #search.result(distinct: true).page(params[:page]).per(params[:per])
respond_with #orders.as_json(include: :items)
end
My client makes the request like so:
#orders = Order.search(q: { client_id_eq: #current_user.id }, page: params[:page], per: 3)`
Back on the server, I have this in my ApiController (app controller for api):
protected
def self.set_pagination_headers(name, options = {})
after_filter(options) do |controller|
results = instance_variable_get("##{name}")
headers["X-Pagination"] = {
total_count: results.total_count,
offset_value: results.offset_value
}.to_json
end
end
In the server orders_controller.rb, I set the pagination headers for the search method:
class OrdersController < ApiController
set_pagination_headers :orders, only: [:search]
...
end
Now to receive the headers we need a Faraday middleware in Her on the client.
# config/initializers/her.rb
Her::API.setup url: Constants.api.url do |c|
c.use TokenAuthentication
c.use HeaderParser # <= This is my middleware for headers
c.use Faraday::Request::UrlEncoded
c.use Her::Middleware::DefaultParseJSON
c.use Faraday::Adapter::NetHttp
c.use Faraday::Response::RaiseError
end
# lib/header_parser.rb
# don't forget to load this file in application.rb with something like:
# config.autoload_paths += Dir[File.join(Rails.root, "lib", "*.rb")].each { |l| require l }
class HeaderParser < Faraday::Response::Middleware
def on_complete(env)
unless env[:response_headers]['x-pagination'].nil?
# Set the global var for pagination
$pagination = JSON.parse(env[:response_headers]['x-pagination'], symbolize_names: true)
end
end
end
Now back in your client controller, you have a global variable of hash called $pagination; mine looks like this:
$pagintation = { total_count: 0, offset_value: 0 }`
Finally, I added Kaminari gem to my client app to paginate the array and get those easy pagination links:
#orders = Kaminari.paginate_array(#orders, total_count: $pagination[:total_count]).page(params[:page]).per(params[:per_page])`
I hope this can help someone else, and if anyone knows a better way to do this, let me know!
You can pass header options to Faraday when setting up the connection, see the docs at http://rubydoc.info/gems/faraday/0.8.7/Faraday/Connection:initialize
Sometimes it helps to do a curl request first, esp. use -vv option for verbose output where you will see all headers. (Maybe you can attach some log outputs from the Server too)
You can use e.g. clogger (http://clogger.rubyforge.org/) do monitor header information on the Rails server side
Currently using Pusher and RSpec.
Pusher.should_receive( :trigger ).with( 'message', { :data => '12345' })
This would work, except the call is Pusher[ 'channel-id' ].trigger...
How to mock this with RSpec?
Well [] is a function name so it can be stubbed. In the Pusher source you see: def_delegators :default_client, :webhook, :channel, :[] So all of these methods are forwarded to default_client. So this is actually a chain of methods.
I would do what you want to do like this.
mock_client = mock('client')
Pusher.stub(:[]).with('channel-id').and_return(mock_client)
mock_client.should_receive( :trigger ).with( 'message', { :data => '12345' })
I do not have rspec handy right now, but see no reason why it would not work.
Newer versions of Pusher support a shallower API that is easier to stub:
expect(Pusher).to receive(:trigger).with("channel-id", "message", { data: "12345" })
Pusher.trigger("channel-id", "message", { data: "12345" })
There is also pusher-fake which starts up a fake server for your tests, so you don't have to stub – it lets your app both send and receive via that fake server.
Michael Papile's answer is essentially correct. Here's the code I used:
Pusher.stub_chain( :[] , :trigger )
Pusher[ channel_id ].should_receive( :trigger ).with( 'message', { :data => '12345' })
Actually, it turns out this code does not work because it does not match channel_id.
Is there any example of WSDL Parser using SOAP4R? I'm trying to list all operations of WSDL file but I can't figure it out :( Can you post me some tutorial?
Thx
Maybe that isn't answer you want, but I recommend you switch to Savon. For example, your task looks like this snippet (this example taken from github's savon page):
require "savon"
# create a client for your SOAP service
client = Savon::Client.new("http://service.example.com?wsdl")
client.wsdl.soap_actions
# => [:create_user, :get_user, :get_all_users]
# execute a SOAP request to call the "getUser" action
response = client.request(:get_user) do
soap.body = { :id => 1 }
end
response.body
# => { :get_user_response => { :first_name => "The", :last_name => "Hoff" } }
