I'm trying to POST the following data to a Rails server (running on WebRick) from Android.
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<data>
<email>email.test#name.com</email>
<password>APassw0rd</password>
<remember_me>1</remember_me>
</data>
Now, the funny thing is that these data never show up in the params field in the controller.
Webrick does not output any parsing error. (And I guess it would post an error if it received a POST with no data attached:
Started POST "/users/sign_in.xml" for 192.168.1.94 at 2012-12-14 17:33:20 +0100
Processing by Users::SessionController#create as XML
Completed 500 Internal Server Error in 22643ms
I also found no trace of the data in the request.env variable. Actually, I see no HTTP_BODY in the dump fields. How can one see the raw body of the request? Would webrick really not complain if it received a POST with no attached data?
request.env would show the data as an IO object so you wouldn't be able to see your xml directly.
request.raw_post should return the raw data.
For rails to try and parse your xml into the params hash directly you need to set the content type of the request to application/xml. The 'processing as xml' stuff means that rails will try to render an xml response and doesn't necessarily have any bearing on the format of the posted data

I am working on the implementation of a payment system on my website. But as the payment system works according to the old model, all requests go through XML. I need to send XML (the code is attached below) to the URL and get a response. How could i send XML post request with Ruby on Rails. I need to send in to this url https://setmpos.ykb.com/PosnetWebService/XML?xmldata=%3CposnetRequest%3E%0D%0A++%3Cmid%3E... Where xmldata is query parametr.

I am trying to upload a csv file to Rails and parse it into a db. I have tried using both Paw and Postman to send the http request, specifying POST, attaching the csv file, and specifying Content-Type as application/csv
The request header:
POST /skate_parks/import HTTP/1.1
Content-Type: text/csv
Host: localhost:3000
Connection: close
User-Agent: Paw/2.3.4 (Macintosh; OS X/10.11.5) GCDHTTPRequest
Content-Length: 11663
Name,Address,Suburb,Postcode,State,Business Category,LGA,Region,
Aireys Inlet Skate Park,Great Ocean Road,Aireys Inlet,3231,VIC,Skate Parks,Surf Coast,Barwon S/W, etc...
The controller skate_parks_controller.rb
def import
SkatePark.import(params[:body])
end
The model
class SkatePark < ApplicationRecord
require 'csv'
def self.import(file)
CSV.foreach("file", headers: true) do |row|
skate_park_hash = row.to_hash
skate_park = SkatePark.where(name: skate_park_hash["name"])
if skate_park.count == 1
skate_park.first.update_attributes(skate_park_hash)
else
SkatePark.create!(skate_park_hash)
end
end
end
end
The error
Started POST "/skate_parks/import" for ::1 at 2016-05-26 13:48:34 +1000
Processing by SkateParksController#import as HTML
Completed 500 Internal Server Error in 3ms (ActiveRecord: 0.0ms)

The problem is params[:body] is nil, so you're essentially calling SkatePark.import(nil). Rails doesn't put the raw POST body into params like you've apparently assumed it does.
You have two options. The better option, in my opinion, is to upload the data as multipart/form-data. Rather than putting the raw data into the POST body, you'll do the same thing a browser does when a user chooses a file in an <input type="file">, which is to say you'll encode it as form data. When you do that, you will be able to access the data through params, as described in the Form Helpers Rails Guide under "Uploading Files." (Since you apparently aren't using a form, you can skip to "What Gets Uploaded" to see how to handle the data you receive.)
To test this with Postman, follow the instructions for "form-data" under "Request body" in the Sending Requests docs, which I'll excerpt here for posterity:
multipart/form-data is the default encoding a web form uses to transfer data. This simulates filling a form on a website, and submitting it. The form-data editor lets you set key/value pairs (using the key-value editor) for your data. You can attach files to a key as well.
Your other option is to access the POST body directly via request.raw_post as described here: How to access the raw unaltered http POST data in Rails? This is not very "Railsy," however, and among other things will be harder to test.
I send a get request to a local (separate from app) jetty web server
RestClient.get("ip/command/core/get-version", {})
Then I do a JSON.parse() on the response.
As a result I get
{"revision"=>"r2407", "full_version"=>"2.5 [r2407]", "full_name"=>" [r2407]", "version"=>"2.5"}
What's wrong? How do I turn it into a hash, so I can extract the full_version property?
String returned by service is html encoded. Try decoding it first:
JSON.parse(CGI.unescape_html(response_body))
Your JSON response looks to be encoded into HTML entities.
If you are using Ruby, try decoding the response using CGI.unescape_html prior to running JSON.parse. Running the result of that method through JSON.parse should give you your hash.
We have a function in our Rails code that accepts a JSON POST body:
contacts = ActiveSupport::JSON.decode(request.raw_post.gsub("+", ""))
(I'm aware that I can get this from params["_json"] as well, but we have extremely large (MBs) POST bodies that do not get put into params["_json"] for some reason (and + throws errors too).
Since the JSON is usually sent from a mobile client, it's important to us to optimize the upload size. We want to switch to having the POST body gzipped.
However, no matter what we do, we get the same error with no line number:
MultiJson::DecodeError (743: unexpected token at ''):
We have tried:
gzipped_contacts = Zlib::GzipReader.new(StringIO.new(request.raw_post)).read
contacts = ActiveSupport::JSON.decode(gzipped_contacts.gsub("+", ""))
This:
gzipped_contacts = ActiveSupport::Gzip.decompress(request.raw_post)
contacts = ActiveSupport::JSON.decode(gzipped_contacts.gsub("+", ""))
And the solution found here: Rails: how to unzip a compressed xml request body?
I'm pretty sure this is not occurring at the controller level because I can't log anything there, so it needs to be done in the middleware or at the server (but I can't find anything for Nginx that lets us deflate). Please assist!
Ok, turns out the iPhone client was sending the wrong headers. So the solution for anyone encountering this is to see the advice here:
Rails: how to unzip a compressed xml request body?
And verify that you are sending Content-Type: gzip/json.
I am working on a flex application which communicates with a Rails backened.
When i request for some data, It sends back xml feed.
In some cases, if given parameters are not valid, then rails return an error feed with status code = 422 as following
email is wrong
But I dont get this feed in FaultEvent of Flex, How could i read error feed?
Thanks
Are you getting the result in ResultEvent in such cases? I am not sure for what all HTTP error codes FaultEvent will get invoke(I know only it goes for 404 and 500). May be its still going to ResultEvent as a valid result!
You can use HTTPService instead of URLLoader.
Flex HTTP results will not include the actual underlying HTTP response codes. It just doesn't work. (TM)
