I am writing a code that send http post request. Now I write xml body in my code, and its working correctly.
But if I want to send request using xml file I get
undefined method `bytesize' for #
Did you mean? bytes
My code below
require 'net/http'
request_body = <<EOF
<xml_expamle>
EOF
uri = URI.parse('http://example')
post = Net::HTTP::Post.new(uri.path, 'content-type' => 'text/xml; charset=UTF-8')
post.basic_auth 'user','passcode'
Net::HTTP.new(uri.host, uri.port).start {|http|
http.request(post, request_body) {|response|
puts response.body
}
}
**But if I want to make send file**
require 'net/http'
request_body = File.open('example/file.xml')
uri = URI.parse('http://example')
post = Net::HTTP::Post.new(uri.path, 'content-type' => 'application/xml; charset=UTF-8')
post.basic_auth 'user','passcode'
Net::HTTP.new(uri.host, uri.port).start {|http|
http.request(post, request_body) {|response|
puts response.body
}
}
I get
undefined method `bytesize' for #
Did you mean? bytes
You need to load the file content to memory if you want to use it as a request body, use #read method:
request_body = File.open('example/file.xml').read
and it'll work.

I request information from an HTTP streaming service. It provides data in JSON format. Here is the documentation. Here is a part of the code I am using:
require 'uri'
require 'net/https'
require 'json'
uri = URI("https://api.tradier.com/v1/markets/events/session")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
http.read_timeout = 30
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
# Headers
request["Accept"] = "application/json"
request["Authorization"] = "Bearer xxx"
# Send synchronously
response = http.request(request)
# parses response
parse = JSON.parse(response.body)
#out puts values only from response
sessionid = parse.values[0]["sessionid"]
url = parse.values[0]["url"]
uri = URI("#{url}?sessionid=#{sessionid}&symbols=aapl")
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
http.read_timeout = 30
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
# Headers
request["Accept"] = "application/json"
request["Authorization"] = "Bearer xxx"
http.request request do |response|
response.read_body do |data|
puts data.class
# info = JSON.parse(data, :quirks_mode => true)
# puts info.values
end
end
I want to have the system continue the program. It seems that I need to use begin and rescue, but I cannot get them to work. When I request data, I get the following error:
`parse': 757: unexpected token at '{"type":"trade","symbol":"AAPL","exch":"Q","price":"191.23","size":"1081622","cvol":"18308460","date":"1528747200000","last":"191.23"}{"type":"summary","symbol":"AAPL","open":"191.35","high":"191.97","low":"190.21","prevClose":"191.7","close":"191.23"}' (JSON::ParserError)
The endpoint you are using is documented in Tradier API docs and it's a streaming endpoint.
It appears that the response is not chunked to contain just one JSON document per chunk. It however does appear that the documents are separated by linefeeds, making the response look like:
{ "json": "data" }
{ "more": "data" }
And that is not valid JSON. You probably need to parse them one by one by doing something like:
http.request request do |response|
response.read_body do |data|
data.each_line do |chunk|
info = JSON.parse(chunk)
puts info.inspect
end
end
end
If the response chunking happens in the middle of JSON documents, you must use some kind of buffered reader.
I have a Ruby script that issues a GET request to a restful API, but it ignores the params that I'm trying to pass in. I want to just get the activated users but it returns all of the users.
Am I not passing in my params correctly? This is my script:
require 'net/http'
require 'net/https'
require 'time'
require 'api-auth'
require 'json'
URL = 'https://<instance name>.mingle-api.thoughtworks.com/api/v2/users.xml'
OPTIONS = {:access_key_id => '<sign in name>', :access_secret_key => '<secret key>'}
PARAMS = {:user => { :activated => true } }
def http_get(url, options={}, params)
uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
body = params.to_json
request = Net::HTTP::Get.new(uri.request_uri)
request.body = body
request['Content-Type'] = 'application/json'
request['Content-Length'] = body.bytesize
ApiAuth.sign!(request, options[:access_key_id], options[:access_secret_key])
response = http.request(request)
users = response.body
if response.code.to_i > 300
raise StandardError, <<-ERROR
Request URL: #{url}
Response: #{response.code}
Response Message: #{response.message}
Response Headers: #{response.to_hash.inspect}
Response Body: #{response.body}
ERROR
end
puts users
end
http_get(URL, OPTIONS, PARAMS)
The response is XML of users, formatted like this:
<user>
<id type="integer">2228</id>
<name>NAME</name>
<login>example#example.com</login>
<email>example#example.com</email>
<light type="boolean">false</light>
<icon_path nil="true"></icon_path>
<activated type="boolean">true</activated>
<admin type="boolean">false</admin>
</user>
I'm still a beginner when it comes to coding, so any help is greatly appreciated! Thank you!
You are putting the parameters for the get request in the body, when you should be placing them in the URL, so that the end of the URL looks something like this:
?param1=value1¶m2=value2
Use a function like this (source):
require 'uri'
def hash_to_query(hash)
return URI.encode(hash.map{|k,v| "#{k}=#{v}"}.join("&"))
end
When you create the URI:
uri = URI.parse("#{url}?#{hash_to_query(params)}")
Passing the params via the URL did not work for me.
I ended up pulling the data from the XML that was returned instead of narrowing the search. This returns the correct data:
require 'net/http'
require 'net/https'
require 'time'
require 'api-auth'
require 'json'
require 'nokogiri'
URL = 'https://<instance name>.mingle-api.thoughtworks.com/api/v2/users.xml'
OPTIONS = {:access_key_id => '<sign in name>', :access_secret_key => '<secret key>'}
def http_get(url, options={})
uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
request = Net::HTTP::Get.new(uri.request_uri)
ApiAuth.sign!(request, options[:access_key_id], options[:access_secret_key])
response = http.request(request)
users = response.body
if response.code.to_i > 300
raise StandardError, <<-ERROR
Request URL: #{url}
Response: #{response.code}
Response Message: #{response.message}
Response Headers: #{response.to_hash.inspect}
Response Body: #{response.body}
ERROR
end
return users
end
def extract_active_users
all_users = Nokogiri::XML(http_get(URL, OPTIONS))
all_users.search('//user').each do |user|
active_user = user.xpath('activated')
if active_user.text == 'true'
puts user
end
end
end
extract_active_users
require 'net/http'
require 'rubygems'
require 'json'
url = URI.parse('http://www.xyxx/abc/pqr')
resp = Net::HTTP.get_response(url) # get_response takes an URI object
data = resp.body
puts data
this is my code in ruby, resp.data is giving me data in xml form.
rest api return xml data by default , and json if header content-type is application/json.
but i want data in json form.for this i have to set header['content-type']='application/json'.
but i do not know , how to set header with get_response method.to get json data.
def post_test
require 'net/http'
require 'json'
#host = '23.23.xxx.xx'
#port = '8080'
#path = "/restxxx/abc/xyz"
request = Net::HTTP::Get.new(#path, initheader = {'Content-Type' =>'application/json'})
response = Net::HTTP.new(#host, #port).start {|http| http.request(request) }
puts "Response #{response.code} #{response.message}: #{response.body}"
end
Use instance method Net::HTTP#get to modify the header of a GET request.
require 'net/http'
url = URI.parse('http://www.xyxx/abc/pqr')
http = Net::HTTP.new url.host
resp = http.get("#{url.path}?#{url.query.to_s}", {'Content-Type' => 'application/json'})
data = resp.body
puts data
You can simply do this:
uri = URI.parse('http://www.xyxx/abc/pqr')
req = Net::HTTP::Get.new(uri.path, 'Content-Type' => 'application/json')
res = Net::HTTP.new(uri.host, uri.port).request(req)
I'm sending a request with custom headers to a web service.
require 'uri'
require 'net/http'
uri = URI("https://api.site.com/api.dll")
https = Net::HTTP.new(uri.host, uri.port)
https.use_ssl = true
headers =
{
'HEADER1' => "VALUE1",
'HEADER2' => "HEADER2"
}
response = https.post(uri.path, headers)
puts response
It's not working, I'm receiving an error of:
/usr/lib/ruby/1.9.1/net/http.rb:1932:in `send_request_with_body': undefined method `bytesize' for #<Hash:0x00000001b93a10> (NoMethodError)
How do I solve this?
P.S. Ruby 1.9.3
Try this:
For detailed documentation, take a look at:
http://www.rubyinside.com/nethttp-cheat-sheet-2940.html
require 'uri'
require 'net/http'
uri = URI('https://api.site.com/api.dll')
https = Net::HTTP.new(uri.host, uri.port)
https.use_ssl = true
request = Net::HTTP::Post.new(uri.path)
request['HEADER1'] = 'VALUE1'
request['HEADER2'] = 'VALUE2'
response = https.request(request)
puts response
The second argument of Net::HTTP#post needs to be a String containing the data to post (often form data), the headers would be in the optional third argument.
As qqx mentioned, the second argument of Net::HTTP#post needs to be a String
Luckily there's a neat function that converts a hash into the required string:
response = https.post(uri.path, URI.encode_www_form(headers))
How do I send a JSON request in ruby? I have a JSON object but I dont think I can just do .send. Do I have to have javascript send the form?
Or can I use the net/http class in ruby?
With header - content type = json and body the json object?
uri = URI('https://myapp.com/api/v1/resource')
body = { param1: 'some value', param2: 'some other value' }
headers = { 'Content-Type': 'application/json' }
response = Net::HTTP.post(uri, body.to_json, headers)
require 'net/http'
require 'json'
def create_agent
uri = URI('http://api.nsa.gov:1337/agent')
http = Net::HTTP.new(uri.host, uri.port)
req = Net::HTTP::Post.new(uri.path, 'Content-Type' => 'application/json')
req.body = {name: 'John Doe', role: 'agent'}.to_json
res = http.request(req)
puts "response #{res.body}"
rescue => e
puts "failed #{e}"
end
HTTParty makes this a bit easier I think (and works with nested json etc, which didn't seem to work in other examples I've seen.
require 'httparty'
HTTParty.post("http://localhost:3000/api/v1/users", body: {user: {email: 'user1#example.com', password: 'secret'}}).body
This works on ruby 2.4 HTTPS Post with JSON object and the response body written out.
require 'net/http' #net/https does not have to be required anymore
require 'json'
require 'uri'
uri = URI('https://your.secure-url.com')
Net::HTTP.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https') do |http|
request = Net::HTTP::Post.new(uri, 'Content-Type' => 'application/json')
request.body = {parameter: 'value'}.to_json
response = http.request request # Net::HTTPResponse object
puts "response #{response.body}"
end
real life example, notify Airbrake API about new deployment via NetHttps
require 'uri'
require 'net/https'
require 'json'
class MakeHttpsRequest
def call(url, hash_json)
uri = URI.parse(url)
req = Net::HTTP::Post.new(uri.to_s)
req.body = hash_json.to_json
req['Content-Type'] = 'application/json'
# ... set more request headers
response = https(uri).request(req)
response.body
end
private
def https(uri)
Net::HTTP.new(uri.host, uri.port).tap do |http|
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
end
end
end
project_id = 'yyyyyy'
project_key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
url = "https://airbrake.io/api/v4/projects/#{project_id}/deploys?key=#{project_key}"
body_hash = {
"environment":"production",
"username":"tomas",
"repository":"https://github.com/equivalent/scrapbook2",
"revision":"live-20160905_0001",
"version":"v2.0"
}
puts MakeHttpsRequest.new.call(url, body_hash)
Notes:
in case you doing authentication via Authorisation header set header req['Authorization'] = "Token xxxxxxxxxxxx" or http://api.rubyonrails.org/classes/ActionController/HttpAuthentication/Token.html
A simple json POST request example for those that need it even simpler than what Tom is linking to:
require 'net/http'
uri = URI.parse("http://www.example.com/search.json")
response = Net::HTTP.post_form(uri, {"search" => "Berlin"})
I like this light weight http request client called `unirest'
gem install unirest
usage:
response = Unirest.post "http://httpbin.org/post",
headers:{ "Accept" => "application/json" },
parameters:{ :age => 23, :foo => "bar" }
response.code # Status code
response.headers # Response headers
response.body # Parsed body
response.raw_body # Unparsed body
It's 2020 - nobody should be using Net::HTTP any more and all answers seem to be saying so, use a more high level gem such as Faraday - Github
That said, what I like to do is a wrapper around the HTTP api call,something that's called like
rv = Transporter::FaradayHttp[url, options]
because this allows me to fake HTTP calls without additional dependencies, ie:
if InfoSig.env?(:test) && !(url.to_s =~ /localhost/)
response_body = FakerForTests[url: url, options: options]
else
conn = Faraday::Connection.new url, connection_options
Where the faker looks something like this
I know there are HTTP mocking/stubbing frameworks, but at least when I researched last time they didn't allow me to validate requests efficiently and they were just for HTTP, not for example for raw TCP exchanges, this system allows me to have a unified framework for all API communication.
Assuming you just want to quick&dirty convert a hash to json, send the json to a remote host to test an API and parse response to ruby this is probably fastest way without involving additional gems:
JSON.load `curl -H 'Content-Type:application/json' -H 'Accept:application/json' -X POST localhost:3000/simple_api -d '#{message.to_json}'`
Hopefully this goes without saying, but don't use this in production.
The net/http api can be tough to use.
require "net/http"
uri = URI.parse(uri)
Net::HTTP.new(uri.host, uri.port).start do |client|
request = Net::HTTP::Post.new(uri.path)
request.body = "{}"
request["Content-Type"] = "application/json"
client.request(request)
end
data = {a: {b: [1, 2]}}.to_json
uri = URI 'https://myapp.com/api/v1/resource'
https = Net::HTTP.new uri.host, uri.port
https.use_ssl = true
https.post2 uri.path, data, 'Content-Type' => 'application/json'
Using my favourite http request library in ruby:
resp = HTTP.timeout(connect: 15, read: 30).accept(:json).get('https://units.d8u.us/money/1/USD/GBP/', json: {iAmOne: 'Hash'}).parse
resp.class
=> Hash
