I have a request that looks like this;
uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
request.body = purchase_xml
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
response = http.request(request)
result = Hash.from_xml(response.body)
However result = Hash.from_xml(response.body) gives me this error:
#<RuntimeError: Illegal character '&' in raw string "ybs_autocreate_status=ERROR&ybs_auto
Change any instances of & to & when you are not referring to a character code.

Trying to parse the json string with JSON.parse I get unexpected token error
require "net/http"
require "uri"
url = URI.parse("https://url-goes-here")
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
req = Net::HTTP::Get.new(url.request_uri)
req['Accept'] = 'application/json'
res = Net::HTTP.new(url.host, url.port).start do |http|
http.request(req)
end
json = JSON.parse(res)
puts json
Data in response looks like JSONP, rather old method of doing rpc. Instead of returning plain JSON it outputs some_js_callback_function_name({here_goes: the_json}), usually there's also a parameter that controls the function name.
To get json from it - trim the function call before parsing:
json_data = res.body.gsub(/\A[^(]+\(/, '').gsub(/\)\s*\z/, '')
json = JSON.parse(json_data)
I have a Rails 5 app and have a form where I want the user to enter their email address and be added as a contact. THIS QUESTION go me pretty close. The response error I am getting is: {"errors":[{"field":null,"message":"access forbidden"}]}which looks like an authentication issue. Here is my code...
def email_signup
email_address = params[:email_address]
url = URI("https://api.sendgrid.com/v3/contactdb/recipients")
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new(url)
request["authorization"] = 'Bearer <<my_api_key>>'
request["content-type"] = 'application/json'
request.body = "[{\"email\" : email_address}]"
response = http.request(request)
redirect_to jobs_url, notice: response.read_body
end
What am I missing?
OK...I had two issues that needed to be addressed. First, I had the << in the string portion of my API key, the other was that the request body wasn't formatted quite right. Here is what worked for me:
def email_signup
email_address = params[:email_address]
url = URI("https://api.sendgrid.com/v3/contactdb/recipients")
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new(url)
request["authorization"] = 'Bearer SG.Q9sdfsd9s098sdf89sf809sdf809sd'
request["content-type"] = 'application/json'
request.body = [{"email": email_address}].to_json
response = http.request(request)
redirect_to jobs_url, notice: response.read_body
end
I’m using Rails 4.2.7 and this code for making a Net::Http get request
req = Net::HTTP::Get.new(url)
if !headers.nil?
headers.each do |k, v|
req[k] = v
end
end
res = Net::HTTP.new(uri.host, uri.port).start do |http|
http.use_ssl = (uri.scheme == "https")
http.request(req)
end
status = res.code
content_type = res['content-type']
content_encoding = res['content-encoding']
content = res.body
However, when I make one in which the scheme is “https”, I get the following error
Error during processing: use_ssl value changed, but session already started
/Users/davea/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/net/http.rb:758:in `use_ssl='
/Users/davea/Documents/workspace/myproject/app/helpers/webpage_helper.rb:118:in `block in get_content'
/Users/davea/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/net/http.rb:853:in `start'
How do I set https while still being able to make my GET request?
According to docs, use_ssl
must be set before starting session.
This is my usual flow:
uri = URI 'some endpoint with encoded params'
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
headers = headers.each_with_object({}) { |(k, v), hash| hash[k] = v }
http.get(uri.request_uri, initheader = headers)
See the docs on get.
Sidenote on your
if !headers.nil?
It would be more readable if you just check for presence:
if headers.present?
Or even shorter:
if headers # would return true unless it's nil or false
In Ruby 2.0.0p195, Rails 4.0.0, Net::HTTP::Post.new request returns empty body of response.
#toSend = {
"zuppler_store_id" => 'X3r82l89',
"user_id" => '1'
}.to_json
uri = URI("http://smoothpay.com/zuppler/gen_token_post.php")
http = Net::HTTP.new(uri.host,uri.port)
req = Net::HTTP::Post.new uri
req.content_type = "application/json"
req.body = #toSend # or "[ #{#toSend} ]" ?
res = Net::HTTP.start(uri.host, uri.port) {|http| http.request(req)}
puts "Response #{res.code} - #{res.message}: #{res.body}"
This code returns "Response 200 - OK:"
But it should return like this: {"result":"success","token":"843e5be88fb8cee7d324244929177b4e"}
You can check it by typing this url:
http://smoothpay.com/zuppler/gen_token_test.php
Why is res.body empty?
Seems like that service doesn't like the POST request to be application/json.
This works:
uri = URI("http://smoothpay.com/zuppler/gen_token_post.php")
http = Net::HTTP.new(uri.host,uri.port)
req = Net::HTTP::Post.new uri
req.body = "zuppler_store_id=X3r82l89&user_id=1"
res = Net::HTTP.start(uri.host, uri.port) {|http| http.request(req)}
res.body # => "{\"result\":\"success\",\"token\":\"9502e49d454ab7b7dd2699a26f742cda\"}"
In other words, give the service application/x-www-form-urlencoded. Peculiarly, it will hand you back text/html which you'll have to JSON.parse. Weird service.
I am trying to get json form url :
uri = URI.parse("http://84.38.185.251:9262/send")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
response.code # => 301
response.body # => The body (HTML, XML, blob, whatever)
response["cache-control"] # => public, max-age=2592000
puts response.body
but i get an error :`EOFError (end of file reached):
app/controllers/sensors_controller.rb:35:in sensinfo'
sensors_controller.rb:35:
response = http.request(request)
What am i did wrong?
this error mostly get for using https
If it is https then
Please try this one
uri = URI.parse("https://84.38.185.251:9262/send")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Get.new(uri.request_uri)
http.use_ssl = true
response = http.request(request)
Note aditional
http.use_ssl = true
If it is not https
http.use_ssl = false
or you can add the condition
http.use_ssl = true if domain =~ /^https/
you can get more on this https://web.archive.org/web/20140226183826/http://expressica.com/2012/02/10/eoferror-end-of-file-reached-issue-when-post-a-form-with-nethttp/
I think it is a some sort of bug; typhoeus seems to work:
require 'typhoeus'
response = Typhoeus.get("http://84.38.185.251:9262/send")
p response.body
#=> {"ids":"-1","data":{"temp":"nan","h":"-1"},"status":"255","voltage":"-1"}
