Is it possible to make Savon allow redirects? I am currently receiving a 302 HTTP Error, but in reality this should just be a redirect instead of an error.
You can setup Savon to follow redirect setting up follow_redirects option to true.
Eg: client = Savon.client(wsdl: url, ssl_verify_mode: :none, follow_redirects: true)
Found here: https://github.com/savonrb/savon/issues/243
Savon uses httpi for the connection. httpi itself is a wrapper around curb, em_http, excon, httpclient, net_http and rack.
The file em_http.rb contains the comment that
automatic redirect following
is not supported by httpi.
So what I would try to send the call to the redirection target right away if that's possible.
To find the "real" URL you can use a tool like curl, for example:
curl -I www.yahoo.in
gives you
HTTP/1.1 301 Moved Permanently
Date: Thu, 18 Aug 2016 18:50:05 GMT
...

Location: http://in.yahoo.com/
Vary: Accept-Encoding
Content-Type: text/html; charset=UTF-8

The Location: key shows the address you want to try next. You might get another redirect. You'll have to try until the 200 OK is returned.

I have two DotNet MVC sites. One accesses a Web API from the other with an AJAX GET call.
This all worked, but has stopped functioning now. I've hardly made any changes on my side, so I'm wondering if my host might have made changes (in IIS, for example) that would stop this from working?
Here's how I initially got it working...
I installed the Microsoft.Aspnet.Cors and Microsoft.Aspnet.WebApi.Cors packages.
I added the following code...
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.EnableCors();
And in the controller for my API I added...
namespace Webscope.Controllers
{
[EnableCors(origins: "[URL of my other website]", headers: "*", methods: "*")]
public class EventAPIController : ApiController
This used to work, but now get the following error in the console:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https:[my website URL]/EventRead/1-1-2015/12-12-2099. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).
In response to #FoggyDay's answer below, I've called the API from Fiddler and got the following headers...
HTTP/1.1 200 OK
Cache-Control: no-cache
Pragma: no-cache
Content-Type: application/json; charset=utf-8
Expires: -1
Server: Microsoft-IIS/8.0
X-AspNet-Version: 4.0.30319
X-Frame-Options: AllowAll
X-Powered-By: ASP.NET
Date: Fri, 13 Mar 2020 03:56:39 GMT
Content-Length: 198
So it looks as if CORS headers have not been included in the response. Can anyone tell me why this would be?
UPDATE
I found some extraneous code from a previous attempt to get CORS working. Now that I've removed this code, I am seeing the CORS headers in Fiddler.
Access-Control-Allow-Headers: *
Access-Control-Allow-Methods: *
Access-Control-Allow-Origin: https://[ calling website's URL ]/
However I'm still getting the following error in my calling site's console...
Access to XMLHttpRequest at
'https://[ destination site URL ]/api/EventRead/1-1-2015/12-12-2099' from
origin '[ calling website's URL ]' has been blocked by CORS
policy: Response to preflight request doesn't pass access control
check: No 'Access-Control-Allow-Origin' header is present on the
requested resource.
SUGGESTIONS:
Back out your "new" changes. It sounds like you've inadvertantly introduced a second header.
Read this: Reason: CORS header 'Access-Control-Allow-Origin' missing
Look at your HTTP traffic, for example in Fiddler. Verify that you're sending the header ... and verify that you're allowing the correct combination of host and port.
If you're still having problems, post back with the exact error message and relevant HTTP headers.
I'm building a private Shopify app that returns custom shipping rates. Following the API docs, and with some help from this tutorial, I created a functional, proof-of-concept that returns some sample shipping rates in my store.
However, that proof-of-concept app is built in PHP, and the final version must be in Ruby on Rails. So I created a Rails app that returns exactly the same content as the PHP app—but for some reason the rates simply don't show up in the Shopify backend.
The only thing I notice that's different is the HTTP headers (I've tried monkeying around with them to match the PHP app, but to no avail). Is there anything obvious I'm missing here?
Here's a comparison of the HTTP response headers:
PHP:
Connection: Keep-Alive
Content-Encoding: gzip
Content-Length: 186
Content-Type: text/html; charset=UTF-8
Date: Tue, 16 May 2017 13:00:30 GMT
Keep-Alive: timeout=5, max=100
Server: Apache/2.4.18 (Ubuntu)
Vary: Accept-Encoding
Rails:
Cache-Control: max-age=0, private, must-revalidate
Connection: keep-alive
Content-Encoding: gzip
Content-Type: text/html; charset=utf-8
Date: Tue, 16 May 2017 12:57:38 GMT
ETag: W/"ce885edaa10636b3b7459dca958f44dd"
Server: nginx
Transfer-Encoding: chunked
Vary: Accept-Encoding
X-Request-Id: 54e2575e-c86a-4f44-a315-d0a3fbbc13f9
X-Runtime: 0.616974
Again, Shopify handles the PHP response fine, but fails silently on the Rails response. Is there anything in that second (Rails) block that Shopify might be rejecting?
Shopify unfortunately provides no error log or way to debug this type of issue—either they pull the rates from your app or not.
Here is my Rails rates_controller.rb:
class RatesController < ApplicationController
def index
ups_rates = {
rates: [
{
service_name: 'Endertech Overnight',
service_code: 'ETON',
total_price: '000',
currency: 'USD',
min_delivery_date: (DateTime.now + 1.days).strftime('%F %T %z'),
max_delivery_date: (DateTime.now + 2.days).strftime('%F %T %z')
},
{
service_name: 'Endertech Regular',
service_code: 'ETREG',
total_price: '000',
currency: 'USD',
min_delivery_date: (DateTime.now + 3.days).strftime('%F %T %z'),
max_delivery_date: (DateTime.now + 7.days).strftime('%F %T %z')
}
]
}
# Tested returning both application/json (default) or text/html
#render json: ups_rates
render body: ups_rates.to_json, content_type: "text/html"
end
end
I suspected maybe Shopify was caching very aggressively, so I've also tried destroying and recreating both my private app and the carrier service, as well as changing the callback_url. So far nothing has had any effect.
After a whole lot of digging, I found the answer: Shopify requests rates via POST, but my app was only responding to GET.
As a quick fix, I created a static route in routes.rb:
Rails.application.routes.draw do
post 'customrates', to: 'rates#index'
end
In retrospect, this was clearly stated in the documentation, I just hadn't noticed (after all, a rate request intuitively seems like a GET action).
For anyone else encountering this issue, try sending a POST via CURL to your callback_url, just to verify it's returning what it should:
curl -X POST http://yourcallbackurl.com
I don't know what I do wrong, but everytime I tried to obtain the token (after user authentication of course), the result is always Invalid grant_type parameter or parameter missing
Possibly related to Box API always returns invalid grant_type parameter on obtaining access token
Here is my fiddler result:

Even following the curl example gives the same error. Any help would be appreciated.

Looks like Box requires a correct Content-Type: application/x-www-form-urlencoded request header in addition to properly URL encoding the parameters. The same seems to apply to refresh and revoke requests.
Also, per RFC 6749, the redirect_uri is only
REQUIRED, if the "redirect_uri" parameter was included in the authorization request
as described in Section 4.1.1, and their values MUST be identical.
I was facing a similar issue.
The problem is not with Content-Type.
The issue is with the lifecycle of code you receive.
One key aspect not mentioned in most places is that the code you get on redirect lasts only 30 seconds.
To get the access token and refresh token, you have to make the post request in 30 seconds or less.
If you fail to do that, you get the stated error. I found the info here.
Below code worked for me. Keep in mind, the 30-second rule.
import requests
url = 'https://api.box.com/oauth2/token'
data = [
('grant_type', 'authorization_code'),
('client_id', 'YOUR_CLIENT_ID'),
('client_secret', 'YOUR_CLIENT_SECRET'),
('code', 'XXXXXX'),
]
response = requests.post(url, data=data)
print(response.content)
Hope that helps.
You are missing the redirect URI parameter. Try:
POST https://api.box.com/oauth2/token HTTP/1.1
Host: api.box.com
Content-Length: 157
Expect: 100-continue
Connection: Keep-Alive
grant_type=authorization_code&code=nnqtYcoik7cjtHQYyn3Af8uk4LG3rYYh&client_id=[myclientId]&client_secret=[mysecret]&redirect_uri=[your-redirect-uri]
I have also face same issue implementing oauth2. I have add Content-Type: application/x-www-form-urlencoded. When I add content-type my issue solved.
Check and add valid content-type.
Not sure who might need this in the future but be sure you're sending a POST request to get the access token and not trying to retrieve it by using GET or if you're testing- pasting in the address bar won't work, you need to send a POST request with the data in the BODY and not as query parameter.
Also the code usually lasts for a few seconds, so you need to use it as soon as its sent back.
I'm trying to get the Facebook 'like' button working on a site that has some job listings for different companies - each company can have various incoming links (such as http://apply.co/xentrix_studios or http://apply.co/xentrix_studios/facebook that are redirected to a general list of that company's jobs at http://apply.co/jobs.
Here's the Facebook debug for one of the links: https://developers.facebook.com/tools/debug/og/object?q=apply.co%2Fxentrix_studios
Look at the redirect path. Facebook is going from /xentrix_studios to /jobs to the root at http://apply.co. So, the readings it's giving us are for the root url, which is obviously not what we want.
How can I get Facebook to just stay at the right page after it follows the incoming link?
Your server is returning a 301 redirect for that URL. If you want Facebook to treat a URL as being a real URL, it needs to return content including the meta tags that tell Facebook what image/description/etc to use.
I checked this with
curl -A "facebookexternalhit/1.1" -i "http://apply.co/xentrix_studios"
The response was

Trying for hours to get a request token using Google OAuthGetRequestToken but it always returns "signature_invalid".
For a test I use the oAuth Playground to successfully request the token. Here are the results:

I am using Fiddler to trace my calls. It returns the Signature base string:

Aside from the oauth_timestamp and oauth_nonce (which should be different), the base string are pretty much identical.
Anyone know what I am doing wrong?
Update 11/20/2011 Thinking it might be something wrong with my RSA-SHA signing, I have since tried HMAC-SHA. It gives the same results. I thought it might be beneficial to include the Fiddler results (I added carriage returns to have it format better).

Update 11/24/2011 - I want to add more information based on the answers from #Meysam and #Bob Aman. First, my domain is properly registered with Google. I have been using AuthSub for quite some time now with Target URL path prefix set to http://www.embeddedanalytics.com/authsubsuccess.html. Now when I go to the Manage Domains section it states my oAuth consumer key is www.embeddedanalytics.com. Now perhaps this could be a problem. In the Registration for Web-Based Applications document it states:
If you're using the OAuth interface, this URL (the "Target URL path prefix") must match the value of the oauth_consumer_key parameter
In my case I have a target URL different from my oauth_consumer_key. Could this be a problem? I use www.embeddedanalytics.com as the consumer_key in the playground and it works. I don't want to mess with the target URL because it is currently being used with my AuthSub authorizations.
I assume you have not registered your application domain with Google. Therefore, whatever consumer secret you are using to sign your request (in HMAC-SHA1 method) will be denied unless you provide anonymous as your oauth_consumer_key and consumer secret. This way, Google will recognize you as an unregistered application and will successfully return you a Request Token.
If you use the HMAC-SHA1 method, the Consumer Secret and Token Secret will be used to sign your requests. These two secret parameters are known both to your application, and Google, and act like a secret key in a symmetric encryption algorithm.
In order to use RSA-SHA1 method however, you should have already uploaded your Public Key to the server (Google Server) during the registration process of your application. After that, you will use your Private Key to sign your OAuth requests. In your case, since you have not registered your application, Google is not aware of your Public Key, and therefore using RSA-SHA1 method to sign your requests with an unknown Private Key is of no use.
The first method is usually preferred over the RSA-SHA1 method for performance reasons. (symmetric encryption is faster than asymmetric one)
So this is the way I could successfully get a Request Token in the OAuth Playground:
Set 'oauth_consumer_key' to anonymous (unless you have
registered your application and have a real Consumer Key)
Set 'consumer secret' to anonymous (unless you have registered your
application and have a real Consumer Secret)
Choose https://www.google.com/analytics/feeds/ as the scope of request.
Press 'Request token' button

This will redirect you to the login page of Google (if you are not signed in) and then to the page you grant access to the application.

*Note: One time, I got the signature_invalid response too, even though I had entered anonymous credentials. But after trying again and pressing 'Request token' button one or two more times I made it. I think this should be due to how nonce and timestamp parameters work to sign the request. This could be the cause of problem. Read this article for more info.

Managing the OAuth key and secret
Registration for Web-Based Applications
Googler here. Haven't fielded OAuth 1 questions in a long time because everyone's moving to OAuth 2 (and you should too) but I'll try to go through the usual suspects on invalid signature errors:
Your server's clock may be wrong. There's a timestamp component and it needs to match ours pretty closely. Try updating your clock against one of the major reference time servers. This happens, but it's an uncommon issue.
Depending on how low-level the OAuth client you're using is, you may have forgotten to supply part of the key used to generate the signature. The key has two pieces, colon-separated, IIRC. In some parts of the protocol, only one half is needed, but for other parts of the protocol, you need both. I've seen cases where someone kept supplying only the first half when both were needed. Actually, I think I made this mistake myself a couple times.
Probably not an issue in your case, because you haven't even gotten past the request token, but OAuth 1 requires you to sign the URI query parameters. Failure to do this will cause the signature base strings to mismatch, thus causing the signature to be invalid.
By far the most common issue is improper encoding. This usually gets expressed as signatures that work sometimes, but fail other times, because sometimes you get lucky and nothing needs to get encoded. I suspect this is what #Meysam ran into based on his comment that he pressed the button a few more times and suddenly it worked.
By the way, if you have to use OAuth 1, you should be using HMAC-SHA1 unless you've got a really good reason to do RSA-SHA1.
