Rails 3发布到外部Web服务

Question

Lets say I have a blog post that a user is creating and I want to send all of the data to an external web service as XML with a specific schema so it can be ingested into that web service.

I have been looking into the ActionDispatch::Request

And I read this Using Ruby on Rails to POST JSON/XML data to a web service post and answer

However I got an error saying content_type was not a valid method for request. So I changed that line to call the header method and create a header for content-type with the appropriate information

Ok... so now where to go?

This is my code so far:

url= URI.parse('http://10.29.3.47:8080/ingest')
response = Net::HTTP::Post.new(url.path)
request.headers["Content-Type"] = 'application/json'
request.body = 'all of my xml data and schema which is far too long to type here'
response = Net::HTTP.start(url.host, url.port) {|http| http.request(request)}
assert_equal '201 Created', response.get_fields('Status')

I get an error saying that request.body is also not a valid method call, but when I look at the API the only thing matching body is "body()" which does not take arguments. So how do I pass the content of my post to the web service?

Thank you for the help!

You had response = Net::HTTP::Post.new(url.path) instead of request = Net::HTTP::Post.new(url.path) and you add headers with add_field .

require 'net/http'
require 'uri'
url= URI.parse('http://10.29.3.47:8080/ingest')
request = Net::HTTP::Post.new(url.path)
request.add_field 'Content-Type', 'application/json'
request.body = 'all of my xml data and schema which is far too long to type here'
response = Net::HTTP.start(url.host, url.port) {|http| http.request(request)}
