I need to call an external url to pull down some information from a remote database.
I tried setting up my call like this:
post_params = {'a' => 'b', 'b' => 'c',}
resp = Net::HTTP.post_form(URI.parse('https:/my.remoteserver.com/'), post_params)
This returns with a 400 Bad Request, however, due to the fact that the url is HTTPS.
If I format the call as a GET, however, and do something like this:
url = URI.parse("https:/my.remoteserver.com?a=b&b=c")
result = Net::HTTP.start(url.host, use_ssl: true, verify_mode: OpenSSL::SSL::VERIFY_NONE) do
|http| http.get url.request_uri, 'User-Agent' => 'MyLib v1.2'
end
Everything works fine. Unfortunately in my specific case I can't use GET. I assume there is a way to do this over POST but I just don't know what that would be. If anyone could help me out with this I'd really appreciate it. Thanks!
The key part of the other answer's link, and cause of your problem could be because you need to set use_ssl = true on the Net::HTTP element:
Example:
post_params = {'a' => 'b', 'b' => 'c',}
uri = URI 'https:/my.remoteserver.com/'
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true if uri.scheme == 'https'
resp = http.post_form(uri, post_params)

I am trying to call external API for my project and I have some troubles while using Net::HTTP in my rails lib . Here is my code
class ApiCall
def self.do_api_request(api_token, body)
require 'net/http'
require 'uri'
uri = URI.parse('https://sample.com')
header = {'Token' => api_token, 'Content-Type' => 'application/json', 'Accept' => 'application/json'}
request = Net::HTTP::Post.new(uri.request_uri, header)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = (uri.scheme == "https")
request.body = body
http.request(request)
end
end
This is how I use it (assume I knew the api_token and body):
body = {'id' => 2, 'age'=> 23};
ApiCall.do_api_request(api_token, body)
This way, it throws an error back:
NoMethodError: undefined method `bytesize' for Hash
Then after check online, seems like the body is hash instead of string, so I did this
body = URI.encode_www_form(body) and after rerun, it gives me :
400 bad request
I have no ideas how to put both header and body into a rails Net::HTTP method
Solution:
I know where the problem is. request body supposed to be string
so body = "{'id' : 2, 'age' : 23}" , I used body.to_json
I will suggest you to use HTTParty for calling an api. This is real simple to use. Following are the examples-
HTTParty.get("https://api.bigcommerce.com/stores/"+#store.store_hash+"/v3/catalog/categories", :headers => #your_header_data)
This will return the response. Also for post request,
HTTParty.post("https://api.bigcommerce.com/stores/"+#store.store_hash+"/v3/catalog/products", :headers => #auth, :body => product_json)
So you can pass body to in body param here.
I've build a listener for my IPN. I can receive the request via IPN Simulator and all the parameters are correct, but when I send it back to link for sending my request to make validations it will ALWAYS return INVALID.
I've tried changing the encoding on my PayPal account to UTF-8 but it didn't work.
I'm not using any gem for this and I'm not looking forward to this.
class PaymentNotificationController [:create] #Otherwise the request from PayPal wouldn't make it to the controller
def create
response = validate_IPN_notification(request.raw_post)
case response
when "VERIFIED"
P 'worked'
when "INVALID"
p 'did not work'
else
end
render :nothing => true, :status => 200, :content_type => 'text/html'
end
protected
def validate_IPN_notification(raw)
uri = URI.parse('https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_notify-validate')
#uri = URI.parse('https://www.paypal.com/cgi-bin/webscr?cmd=_notify-validate')
http = Net::HTTP.new(uri.host, uri.port)
http.open_timeout = 60
http.read_timeout = 60
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
http.use_ssl = true
response = http.post(uri.request_uri, raw,
'Content-Length' => "#{raw.size}",
'User-Agent' => "My custom user agent"
).body
end
end
Please help me, I've been stuck with it all afternoon and can't get it figured out.
I think your problem is not follow exactly what papal requires
From Paypal document
Your listener HTTP POSTs the complete, unaltered message back to PayPal.
Note This message must contain the same fields, in the same order, as the original IPN from PayPal, all preceded by cmd=_notify-validate. Further, this message must use the same encoding as the original.
So you validate function would be:
def validate_IPN_notification(ipn_url)
validate_url = "#{ipn_url}?cmd=_notify-validate"
# Post validate_url
...
end
Note that the ipn_url is the same url of IPN
It turned out to be a Windows problem which I don't know how to fix.
I tried the same thing on my Ubuntu 15 and it worked perfectly.
I am trying to make a http get request as specified in the title.
What I've written:
uri = URI.parse("https://myaddress.com")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
#data = http.get(uri.request_uri)
The request is sent where I want it to be sent and I receive an Unauthorized response (as expected, because I did not specify the basic auth).
I've tried
http.basic_auth 'user', 'pass'
But there's no such method for the type of my http variable.
How can I add the auth details?
Update: I tried to use something like here RUBY - SSL, Basic Auth, and POST, but after replacing Post with Get, I cannot use the 'use_ssl', nor 'verify_mode' attributes (I get no such attribute error).
Update 2: I figured out that I can set the 'use_ssl' attribute on a Net::HTTP object and the 'basic_auth' on a Net::HTTP::Get object.
Now the question is how can I make them work together?
Well, I ended up finding an answer. Maybe this will help others:
url = URI.parse('https://myaddress.com')
req = Net::HTTP::Get.new(url.path)
req.basic_auth 'user', 'pass'
sock = Net::HTTP.new(url.host, url.port)
sock.use_ssl = true
sock.verify_mode = OpenSSL::SSL::VERIFY_NONE
resp = sock.start {|http| http.request(req) }
I am trying to perform an HTTP authorization using Ruby on Rails. Here is what I'm trying:
res = http.post(uri.request_uri,
:Authorization => cobSessionToken,
"coBrandSessionCredential=loginToken=#{cobSessionToken}&userLogin=#{login}&userPassword=#{password}")
render :json => {"isValid" => true, "Body" => JSON.parse(res.body)}
This doesn't seem to work. How can I perform an authorization?
how about something like this?
url = URI.parse('https://my.url.com/path')
req = Net::HTTP::Post.new(url.path)
req.basic_auth 'user', 'pass'
req.use_ssl = true
req.form_data({'key1' => 'val1', 'key2' => 'val2'})
resp = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
puts resp
I would recommend using something like postman (its a free google program you can get at the google store) to make sure the error is not on the server side. Use Net:http it comes with ruby so you do not need to install it but you have to require it.
Require it by:
require "net/http"
require "uri"
Use this cheatsheet I think you need basic_auth.rb You will see how to form the request.
I have multiple bruises today, trying to learn two things at once... the API for Postmark and Rails HTTP requests.
Goal: Use Postmark add-on for Heroku to send production email.
I am trying to combine this article on HTTP requests...
http://docs.ruby-lang.org/en/2.0.0/Net/HTTP.html
... with this API reference for Postmark...
http://developer.postmarkapp.com/developer-send-api.html
Unfortunately, the examples from Postmark are done in curl and I have not succeeded in translating them into a HTTP request. I suspect the problem centers around the headers -- the parts of the transmission other than the body.
The rescue clause seen in the code below traps the error 'connection reset by peer'. At this point I don't know if I am even close to the right format for the headers that provide Postmark authentication.
I have the proper server token (in the config entry) and the From email has been given the required Postmark signature.
def send_production_email(email_address, subject, email_body)
# Use API to interact with Heroku add-on Postmark
# http://developer.postmarkapp.com/developer-send-api.html
uri = URI('https://api.postmarkapp.com/email')
# Form the request
req = Net::HTTP::Post.new(uri)
# Set request headers -- SUSPECT THIS IS WRONG
req['Accept'] = 'application/json'
req['Content-Type'] = 'application/json'
req['X-Postmark-Server-Token'] = Rails.application.config.postmark_token
rbody ={
'From' => 'Support <michael#mydomain.com>',
'To' => email_address,
'Subject' => subject,
'HtmlBody' => wrap_html(email_body),
'TextBody' => email_body
}.to_json
req.body = rbody
# Send the request, waiting for the response
begin
response = Net::HTTP.new(uri.host, uri.port).start {|http| http.request(req) }
rescue Exception => e
logthis("http request error: #{e.message}")
return
end
# ...parsing section omitted since I do not get that far...
end
A second attempt was formatted this way, but results in the same peer reset error:
rbody ={
'From' => 'Support <michael#disambiguator.com>', # TODO: replace email when domain is live
'To' => email_address,
'Subject' => subject,
'HtmlBody' => wrap_html(email_body),
'TextBody' => email_body
}.to_json
uri = URI('https://api.postmarkapp.com/email')
http = Net::HTTP.new(uri.host, uri.port)
# http.use_ssl = true
request = Net::HTTP::Post.new(uri.path, {'Content-Type' => 'application/json', 'Accept' => 'application/json', 'X-Postmark-Server-Token' => Rails.application.config.postmark_token})
request.body = rbody
# Send the request, waiting for the response
begin
response = http.request(request)
rescue Exception => e
logthis("http request error: #{e.message}")
return
end
I am grateful for any guidance!
I’m a Wildbit’s employee and the maintainer of the official Postmark Ruby gem.
The "connection reset by peer" error is the result of you trying to send an unencrypted HTTP request to an endpoint expecting secure communication via HTTPS. So, if you change this line:
Net::HTTP.new(uri.host, uri.port).start {|http| http.request(req) }
to:
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
response = http.start { |http| http.request(req) }
then you should be able to receive a response from the API. I see that you have this line in the second example, but it is commented. Since you’re doing this as an exercise, I’d like to add that when using net/http you don’t usually have to work with the underlying classes like Net::HTTP::Post. It’s generally simpler to use the higher level API provided by instances of the Net::HTTP class. Here is an example of how your method could be simplified by using it:
def send_production_email(email_address, subject, email_body)
uri = URI('https://api.postmarkapp.com/email')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
headers = {'Accept' => 'application/json',
'Content-Type' => 'application/json',
'X-Postmark-Server-Token' => Rails.application.config.postmark_token}
payload = {'From' => 'tema#wildbit.com',
'To' => email_address,
'Subject' => subject,
'HtmlBody' => email_body,
'TextBody' => email_body}
http.post(uri.request_uri, payload.to_json, headers)
rescue => e
puts "http request error: #{e.message}"
end
