Ruby NoMethodError (undefined method `set_body_int

问题:

I am new to Ruby programming. I am trying to get the google XRDS with HTTP GET request, but running in to the NoMethodError (undefined method `set_body_internal') Error. Below is my code. Any help is much appreciated.

require "net/https"
require "uri"

class OpenidController < ApplicationController

  def getOpenIdXRD
    print "Hello...\n"
    uri = URI.parse("https://gmail.com/.well-known/host-meta")
    print "Hello...1\n"
    # Shortcut
    #response1 = Net::HTTP.get_response(uri)

    http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl = true
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE
    print "Hello...2\n"
    File response1 = http.request(request)
    print "Hello...3\n"
    response1.body
    response1.status
    # Will print response.body
    # Net::HTTP.get_print(uri)  
  end

end

Here is my output:

回答1:

You haven't actually assigned a value to the request parameter ...

response1 = http.request(request)

... also ...

File response1 

... doesn't make much sense there - perhaps you want to write the result to a File?

Lastly, if you simply want to do a GET, something based on this should work for you ...

url = " ... insert valid path here ..."

res = Net::HTTP.start('... hostname here ...', 80) {|http|
  http.get(url)
}
puts res.body
