I am making a call to a webservice via HTTPClient ruby gem. The location doesn't matter, but let's say it is at: https://mywebservice.com/api/v1/accounts/login/
When I send a post request:
url = "https://mywebservice.com/api/v1/accounts/login/"
client = HTTPClient.new
client.post url
I get a 404 response, that the page was not found. I setup a proxy and checked out exactly what was being sent it seems like the gem is messing up the url, it actually sends the request to:
https://mywebservice.comhttps://mywebservice.com:443/api/v1/accounts/login/
I am completely lost, I have no why it is doing that. Does it have anything to do with the fact that it's https and I should handle https differently?
Thanks
Yes, if you are requesting a https url do this:
require 'net/http'
require 'net/https'
require 'uri'
uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
#you need to set this field to true
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
response = http.request(request)
Here is a link that should help:
http://bibwild.wordpress.com/2012/04/30/httpclient-is-a-nice-http-client-forin-ruby/
You should post to an uri with a body of params. Something like
client.post "http://mysite.com:8080", data
where data is a hash with the required parameters for the page.
For instance:
data = {"var" => "var"}

I dont know how to put my key into my requests so they are sent back as
{"status"=>"400", "message"=>"Token parameter is required."}
This is the code I have been using
require 'net/http'
require 'json'
token = 'YiwwVvywLngtPT***************'
url = 'https://www.ncdc.noaa.gov/cdo-web/api/v2/stations?locationid=FIPS:23&limit=5&sortfield=mindate'
uri = URI(url)
response = Net::HTTP.get(uri)
response.authorization = token
puts JSON.parse(response)
I have tried a couple different things I've found on the internet but all of them just give errors for
undefined method `methodname' for #<String:0x00007fd97519abd0>
According to the API documentation (based on the URL you referenced), you need to provide the token in a header named token.
So, you should probably try some variation of the below (code untested):
token = 'YiwwVvywLngtPT***************'
url = 'https://www.ncdc.noaa.gov/cdo-web/api/v2/stations?locationid=FIPS:23&limit=5&sortfield=mindate'
uri = URI(url)
request = Net::HTTP::Get.new(uri)
request['token'] = token
response = Net::HTTP.start(uri.hostname, uri.port) do |http|
http.request(request)
end
More information about Net:HTTP headers can be found in this StackOverflow answer.
As a side note, if you are not locked on using Net::HTTP, consider switching to a friendlier HTTP client, perhaps HTTParty. Then, the complete code looks like this:
require 'httparty'
token = 'YiwwVvywLngtPT***************'
url = 'https://www.ncdc.noaa.gov/cdo-web/api/v2/stations?locationid=FIPS:23&limit=5&sortfield=mindate'
response = HTTParty.get url, headers: { token: token }
puts response.body
I try create POST request with SSL but without OpenSSL::SSL::VERIFY_NONE because it is opend up security attacks and without PEM certificate.
But I catch problems, my ruby code for send POST request:
post '/test/test1' do
cross_origin
post_data = request.body.read
res_Data = JSON.parse(post_data)
userName = res_Data['username']
#responseFromServer=''
uri = URI('https://test.com/test1')
Net::HTTP.start(uri.host, uri.port,
:use_ssl => uri.scheme == 'https',
:verify_mode => OpenSSL::SSL::VERIFY_NONE) do |http|
request = Net::HTTP::Post.new uri.request_uri
request.basic_auth 'aa', 'bb'
request.body = {'username' =>userName}.to_json
response = http.request request
#responseFromServer = response.body.to_s
end
newJson = JSON.parse(#responseFromServer)
status_msg = newJson['status']['status_msg']
if (status_msg == "Success")
return 'true'
end
return 'false'
end
It is method worked but he use OpenSSL::SSL::VERIFY_NONE. How to create method for send POST request without OpenSSL::SSL::VERIFY_NONE and PEM sertificate?
EDIT
SSL/HTTPS request
Update: There are some good reasons why this code example is bad. It introduces a potential security vulnerability if it's essential you use the server certificate to verify the identity of the server you're connecting to. There's a fix for the issue though!
require "net/https"
require "uri"
uri = URI.parse("https://secure.com/")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
response.body
response.status
response["header-here"] # All headers are lowercase
SSL/HTTPS request with PEM certificate
require "net/https"
require "uri"
uri = URI.parse("https://secure.com/")
pem = File.read("/path/to/my.pem")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.cert = OpenSSL::X509::Certificate.new(pem)
http.key = OpenSSL::PKey::RSA.new(pem)
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
request = Net::HTTP::Get.new(uri.request_uri)
My question: How to create POST method without PEM and OpenSSL::SSL::VERIFY_NONE?
This question is quite misleading, but I try my best to figure it out. Here is my advise:
Do you want to connect to a service that is only available through https and you do not care if the certificate is valid?
Then you can use :verify_mode => OpenSSL::SSL::VERIFY_NONE when initializing the Net::HTTP client.
You will have some kind of transport security, but you cannot be sure the server you are talking to is the one you think it is. You are vulnerable.
Do you want to connect to a service that is available both through https and http, and you do not care about transport security?
Then you should use the http://... endpoint.
Do you want to connect to a service and you care about transport security?
Then you should definitely use the https://... endpoint.
Do not override :verify_mode!
If you are getting certificate verification errors, make sure you have the correct Certificate Authority installed on your system.
I'm trying to send get request with:
require "net/https"
require "uri"
...
uri = "https://graph.facebook.com/v2.2/#{event_id}?access_token=#{access_token}"
uri = URI.parse(uri)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Get.new(uri.request_uri)
response = http.request(request)
response.body
Facebook sent me an acces_token with | char, and because of it uri = URI.parse(uri) throws an error: URI::InvalidURIError: bad URI(is not URI?) https:/ ....
Is there any other parser, or should I manually extract these host, port, request_uri values? What's the best way of fixing it?
access_token looks like 141112112181111|9Alz3xW7P0CQ_DRomJN2oMeiwXs
event_id is for example 385101904985590
edit: just realized that it's structure is APP_ID|some_token
Have you tried encoding the URI with URI#encode?
uri = 'http://foobar.com?foo=something|weird'
uri = URI.encode(uri)
uri = URI.parse(uri) => #<URI::HTTP:0x007fe2f48775b0 URL:http://foobar.com?foo=something%7Cweird>
Don't try to inject variables into URI query parameters, especially tokens and keys and such as that's a good route to creating an invalid one. Instead, rely on the URI class and let it handle as much as possible.
require 'uri'
event_id = 1
access_token = 'foo|bar'
uri = URI.parse("https://graph.facebook.com/v2.2/#{event_id}")
uri.query = URI.encode_www_form(['access_token', access_token])
uri.to_s # => "https://graph.facebook.com/v2.2/1?access_token&foo%7Cbar"
If you want something more full-featured, Addressable::URI is very nice.
See "Parsing string to add to URL-encoded URL" for more information.
I use Calabsh to test iOS app. Duringtest I need to create POST request to change some values and then verify that changes are reflected in UI.
Request looks like:
wwww.testserver.com/userAddMoney?user_id=1&amount=999
To authorize on server I need to pass special parameters to Header of request:
Headers: X-Testing-Auth-Secret: kI7wGju76kjhJHGklk76
require 'net/http'
uri = URI.parse('http://www.testserver.com/userAddMoney?user_id=1&amount=999')
http = Net::HTTP.new(uri.host,uri.port)
## https.use_ssl = true # use https, need require net/https
req = Net::HTTP::Post.new(uri.path)
req['X-Testing-Auth-Secret'] = 'kI7wGju76kjhJHGklk76'
res = http.request(req)
Docs here: Net::HTTP::Post Net::HTTPSession
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))
