I have written the following code to connect and retrieve a token from the Autodesk. but this does not work properly:
var client = new RestClient("https://accounts.autodesk.com");
client.Authenticator = OAuth1Authenticator.ForRequestToken(consumerKey, consumerSecret);
var request = new RestRequest("OAuth/RequestToken", Method.POST);
var response = await _client.Execute(request);
Executing the request it throws a bad request exception.
Response status code does not indicate success: 400 (Bad Request).
For consumerKey and consumerSecret I respectively used my email and the associated password that I've already registered in accounts.autodesk.com
How can I understand if I'm sending the request in a wrong format or I just send a wrong consumerKey and consumerSecret. And If they are wrong could you please guide me where I can obtain these parameters from Autodesk?
It's not at all your email and password that you need to use but API keys that are generated from your account on our developer portal.
Please sign up or login to the portal: https://developer.autodesk.com/
And follow the step by step tutorial in order to request a token, there are detailed explanations of the workflow there, it can't be easier than that:
https://developer.autodesk.com/en/docs/oauth/v2/tutorials.
I have created a C# sample and a lib but it hasn't been updated yet to use scopes, you can take a look at the discussion in the issues: https://github.com/Developer-Autodesk/view.and.data-dotnet-wpf.tutorial
Finally we are working on generated wrappers for our REST API's so we will be able to produce more stable samples pretty soon. Check out our blog for upcoming news about that: http://adndevblog.typepad.com/cloud_and_mobile

I'm exploring Bitso API (Bitso is a mexican crypto exchange).
The docs of the API is well explained at some languages such as Python and Ruby for its use. The problem here is that there are no examples using straight URLs for request.
What I'm planning to do is to create the URL that the code is creating on its requests function.
There is a request for balance account, that is the data I'd like to get.
According documentation, this is a private request that need some headers at the request (Key, nonce and signature), you can take a look here.
The code to make this request in Python is the following one:
import time
import hmac
import hashlib
import requests
bitso_key = "BITSO_KEY"
bitso_secret = "BITSO_SECRET"
nonce = str(int(round(time.time() * 1000)))
http_method = "GET"
request_path = "/v3/balance/"
json_payload = ""
# Create signature
message = nonce+http_method+request_path+json_payload
signature = hmac.new(bitso_secret.encode('utf-8'),
message.encode('utf-8'),
hashlib.sha256).hexdigest()
# Build the auth header
auth_header = 'Bitso %s:%s:%s' % (bitso_key, nonce, signature)
# Send request
response = requests.get("https://api.bitso.com/v3/balance/", headers={"Authorization": auth_header})
print(response.content)
So based in this I could say that the URL is something like this:
https://api.bitso.com/v3/balance/Bitso%20<Key>:<nonce>:<signature>
I'm sure that I'm wrong with that supposition, I understand that headers={"Authorization": auth_header} seems to be a JSON object used as header in the URL, but I'd like to know how that JSON object is translated at the URL to make a request. I'd like to copy-paste that URL at the browser and get the data as response.
I need that URL so I could use it to connect the service to a Business Intelligence tool.
Thanks!
According to the documentation this Authorization is a header in the request. You can try using postman but you still need hash the destination URL with your api key and the nonce to avoid replay attacks.
I've set up a MediaWiki server on an Azure website with the PluggableAuth and OpenID Connect extensions. The latter uses the PHP OpenID Connect Basic Client library. I am an administrator in the Azure AD domain example.com, wherein I've created an application with App ID URI, sign-on URL and reply URL all set to https://wiki.azurewebsites.net/. When I navigate to the wiki, I observe the following behavior (cookie values omitted for now):
Client Request
GET https://wiki.azurewebsites.net/ HTTP/1.1
RP Request
GET https://login.windows.net/example.com/.well-known/openid-configuration
IP Response
(some response)
RP Response
HTTP/1.1 302 Moved Temporarily
Location: https://login.windows.net/{tenant_id}/oauth2/authorize?response_type=code&redirect_uri=https%3A%2F%2Fwiki.azurewebsites.net%2F&client_id={client_id}&nonce={nonce}&state={state}
Client Request
(follows redirect)
IP Response
HTTP/1.1 302 Found
Location: https://wiki.azurewebsites.net/?code={code}&state={state}&session_state={session_state}
Client Request
(follows redirect)
RP Request (also repeats #2 & #3)
POST https://login.windows.net/{tenant_id}/oauth2/token
grant_type=authorization_code&code={code}&redirect_uri=https%3A%2F%2Fwiki.azurewebsites.net%2F&client_id={client_id}&client_secret={client_secret}
IP Response
(As interpreted by MediaWiki; I don't have the full response logged at this time)
AADSTS50001: Resource identifier is not provided.
Note that if I change the OpenID PHP client to provide the 'resource' parameter in step 8, I get the following error response from AAD instead:
RP Request
POST https://login.windows.net/{tenant_id}/oauth2/token
grant_type=authorization_code&code={code}&redirect_uri=https%3A%2F%2Fwiki.azurewebsites.net%2F&resource=https%3A%2F%2Fwiki.azurewebsites.net%2F&client_id={client_id}&client_secret={client_secret}
IP Response
AADSTS90027: The client '{client_id}' and resource 'https://wiki.azurewebsites.net/' identify the same application.
(This has come up before.)
Update
I've made some progress based on #jricher's suggestions, but after working through several more errors I've hit one that I can't figure out. Once this is all done I'll submit pull requests to the affected libraries.
Here's what I've done:
I've added a second application to the example.com Azure AD domain, with the App ID URI set to mediawiki://wiki.azurewebsites.net/, as a dummy "resource". I also granted the https://wiki.azurewebsites.net/ application delegated access to this new application.
Passing in the dummy application's URI as the resource parameter in step #8, I'm now getting back the access, refresh, and ID tokens in #9!
The OpenID Connect library requires that the ID token be signed, but while Azure AD signs the access token it doesn't sign the ID token. It comes with the following properties: {"typ":"JWT","alg":"none"}. So I had to modify the library to allow the caller to specify that unsigned ID tokens are considered "verified". Grrr.
Okay, next it turns out that the claims can't be verified because the OpenID Provider URL I specified and the issuer URL returned in the token are different. (Seriously?!) So, the provider has to be specified as https://sts.windows.net/{tenant_id}/, and then that works.
Next, I found that I hadn't run the MediaWiki DB upgrade script for the OpenID Connect extension yet. Thankfully that was a quick fix.
After that, I am now left with (what I hope is) the final problem of trying to get the user info from AAD's OpenID Connect UserInfo endpoint. I'll give that its own section.
Can't get the user info [Updated]
This is where I am stuck now. After step #9, following one or two intermediate requests to get metadata and keys for verifying the token, the following occurs:
RP Request:
(Updated to use GET with Authorization: Bearer header, per MSDN and the spec.)
GET https://login.windows.net/{tenant_id}/openid/userinfo
Authorization: Bearer {access_token}
IP Response:
400 Bad Request
AADSTS50063: Credential parsing failed. AADSTS90010: JWT tokens cannot be used with the UserInfo endpoint.
(If I change #10 to be either a POST request, with access_token in the body, or a GET request with access_token in the query string, AAD returns the error: AADSTS70000: Authentication failed. UserInfo token is not valid. The same occurs if I use the value of the id_token in place of the access_token value that I received.)
Help?
Update
I'm still hoping someone can shed light on the final issue (the UserInfo endpoint not accepting the bearer token), but I may split that out into a separate question. In the meantime, I'm adding some workarounds to the libraries (PRs coming soon) so that the claims which are already being returned in the bearer token can be used instead of making the call to the UserInfo endpoint. Many thanks to everyone who's helped out with this.
There's also a nagging part of me that wonders if the whole thing would not have been simpler with the OpenID Connect Basic Profile. I assume there's a reason why that was not implemented by the MediaWiki extension.
Update 2
I just came across a new post from Vittorio Bertocci that includes this helpful hint:
...in this request the application is asking for a token for itself! In Azure AD this is possible only if the requested token is an id_token...
This suggests that just changing the token request type in step 8 from authorization_code to id_token could remove the need for the non-standard resource parameter and also make the ugly second AAD application unnecessary. Still a hack, but it feels like much less of one.
Justin is right. For authorization code grant flow, your must specify the resource parameter in either the authorization request or the token request.
Use &resource=https%3A%2F%2Fgraph.windows.net%2F to get an access token for the Azure AD Graph API.
Use &resource=https%3A%2F%2Fmanagement.core.windows.net%2F to get a token for the Azure Service Management APIs.
...
Hope this helps
Microsoft's implementation of OpenID Connect (and OAuth2) has a known bug where it requires the resource parameter to be sent by the client. This is an MS-specific parameter and requiring it unfortunately breaks compatibility with pretty much every major OAuth2 and OpenID Connect library out there. I know that MS is aware of the issue (I've been attempting to do interoperability testing with their team for quite a while now), but I don't know of any plans to fix the problem.
So in the mean time, your only real path is to hack your client software so that it sends a resource parameter that the AS will accept. It looks like you managed to make it send the parameter, but didn't send a value that it liked.
I had issues getting this running on Azure, even though I got something working locally. Since I was trying to setup a private wiki anyway, I ended up enabling Azure AD protection for the whole site by turning on:
All Settings -> Features -> Authentication / Authorization
From within the website in https://portal.azure.com
This made it so you had to authenticate to Azure-AD before you saw any page of the site. Once you were authenticated a bunch of HTTP Headers are set for the application with your username, including REMOTE_USER. As a result I used the following plugin to automatically log the already authenticated user into Azure:
https://www.mediawiki.org/wiki/Extension:Auth_remoteuser
We have an assignment to check the compatibility of Quick connect project for Foursquare against the REST/JSON 1.1.
When I am testing the process, while invoking Rest API for query Check-in, the process is throwing an error – “OAuth token invalid or revoked”. Can you kindly help to fix this issue.
Access_token for this was generated by registering a sample app with Foursuare.com, having www.google.com as welcome page and redirect URL. Please let me know if this is causing the issue.
Also, let me know is there is any standard method to generate the access_token for this.
Thanks in advance.
Regards,
Shree.
It sounds like you're not following Foursquare's instructions on connecting properly, or need to reconnect to get a new access_token. Keep in mind that the access_token isn't the code that comes back in the redirect, the code needs to be used to exchange for the access_token.
I have successfully created my app and now want to connect it to a localhost to check the working of my app. I have been suggested to use restsharp for connecting to the server using php and json to receive data from server.
I have looked at codes for both but do not completely understand how the process works. I have looked into all forums but found could snippets with no explanation as how it works. I have even tried restsharp.org and google search results. Please explain me as to how this works.
RestSharp is a library that helps you invoking REST web services.
You use RestSharp on your client to invoke Rest style Web Services (send and receive data)
Here is an example on the usage of your service:
var client = new RestClient(baseUrl);
var request = new RestRequest("/*rest_resource*/", Method.POST);
// see Rest services
// set the request format - HTTP Content-Type text/xml
request.RequestFormat = DataFormat.Xml;
// add data to the request
request.AddBody("<books><book>RestSharp Book</book></books>");
/* send the request and if your service returns text put the as expected return type; otherwise you will get raw byte array*/
IRestResponse response = client.Execute(request);
//HTTP status code 200-success
Assert.IsTrue(response.StatusCode == HttpStatusCode.OK);
Assert.IsTrue(!string.IsNullOrEmpty(response.Data)); // the response is not empty
I have a web application for iPhone, which will ultimately run within a PhoneGap application - but for now I'm running it in Safari.
The application needs to access tweets from Twitter friends, including private tweets. So I've implemented OAuth using the Scribe library. I successfully bounce users to Twitter, have them authenticate, then bounce back.
At this point the web app has oAuth credentials (key and token) which it persists locally. From here on I'd like it to user the Twitter statuses/user_timeline.json method to grab tweets for a particular user. I have the application using JSONP requests to do this with unprotected tweets successfully; when it accesses the timeline of a private Twitter feed, an HTTP basic authentication dialog appears in the app.
I believe that I need to provide the OAuth credentials to Twitter, so that my web application can identify and authenticate itself. Twitter recommends doing so through the addition of an HTTP Authorization header, but as I'm using JSONP for the request I don't think this is an option for me. Am I right in assuming this?
My options therefore appear to either be putting the oAuth credentials as query-string parameters (which Twitter recommends against, but documentation suggests still supports); or proxying all the Tweets through an intermediate server. I'd rather avoid the latter.
I access the Twitter API using URLs of the form
http://api.twitter.com/1/statuses/user_timeline.json?user_id=29191439&oauth_nonce=XXXXXXXXXXX&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1272323042&oauth_consumer_key=XXXXXXXXXX&oauth_signature=XXXXXXXXXX&oauth_version=1.0
When user_id is a public user, this works fine. When user_id is a private user, I get that HTTP Basic Auth dialog. Any idea what I'm doing wrong? I'm hoping it's something embarrassingly simple like "forgetting an important parameter"...
The oAuth stanza needs to be exact, as per http://dev.twitter.com/pages/auth#auth-request - I ended up building an Authorization: header that I could first check with curl.
I built it using the really helpful interactive request checker at http://hueniverse.com/2008/10/beginners-guide-to-oauth-part-iv-signing-requests/
Here's a friends API request for a protected user:
curl -v -H 'Authorization: OAuth realm="https://api.twitter.com/1/friends/ids.json", oauth_consumer_key="XXXXXXXXXXXXXXXX", oauth_token="XXXXXXXXXXXXXXXX", oauth_nonce="XXXXXXXXXXXXXXXX", oauth_timestamp="1300728665", oauth_signature_method="HMAC-SHA1", oauth_version="1.0", oauth_signature="XXXXXXXXXXXXXXXX%3D"' https://api.twitter.com/1/friends/ids.json?user_id=254723679
It's worth re-iterating that as you've tried to do, instead of setting the Authorization header via e.g. jquery's beforeSend function, that for cross-domain JSONP requests (which can't add HTTP headers) you can make oAuth requests by putting all the relevant key/value pairs in the GET request. This should hopefully help out various other questioners, e.g
Set Headers with jQuery.ajax and JSONP?
Modify HTTP Headers for a JSONP request
Using only JQuery to update Twitter (OAuth)
Your request looks like it has a couple of problems; it's missing the user's oauth_token plus the oauth_signature doesn't look like it has been base64 encoded (because it's missing a hex encoded = or ==, %3 or %3D%3D respectively).
Here's my GET equivalent using oAuth encoded querystring params, which you can use in a cross-domain JSONP call:
https://api.twitter.com/1/friends/ids.json?user_id=254723679&realm=https://api.twitter.com/1/friends/ids.json&oauth_consumer_key=XXXXXXXXXXXXXXXX&oauth_token=XXXXXXXXXXXXXXXX&oauth_nonce=XXXXXXXXXXXXXXXX&oauth_timestamp=1300728665&oauth_signature_method=HMAC-SHA1&oauth_version=1.0&oauth_signature=XXXXXXXXXXXXXXXX%3D
I was struggling with similar problem of making JSONP requests from Jquery, the above answer helped just to add what I did to achieve my solution.
I am doing server to server oauth and then I send oauth token, secret, consumer key and secret (this is temporary solution by the time we put a proxy to protect consumer secret). You can replace this to token acquiring code at client.
Oauth.js and Sha1.js download link!
Once signature is generated.
Now there are 2 problems:
JSONP header cannot be edited
Signed arguments which needs to be sent as part of oauth have problem with callback=? (a regular way of using JSONP).
As above answer says 1 cannot be done.
Also, callback=? won't work as the parameter list has to be signed and while sending the request to remote server Jquery replace callback=? to some name like callback=Jquery1232453234. So a named handler has to be used.
function my_twitter_resp_handler(data){
console.log(JSON.stringify(data));
}
and getJSON did not work with named function handler, so I used
var accessor = {
consumerSecret: XXXXXXXXXXXXXXXXXXXXXX,
tokenSecret : XXXXXXXXXXXXXXXXXXXXXX
};
var message = { action: "https://api.twitter.com/1/statuses/home_timeline.json",
method: "GET",
parameters: []
};
message.parameters.push(['realm', "https://api.twitter.com/1/statuses/home_timeline.json"]);
message.parameters.push(['oauth_version', '1.0']);
message.parameters.push(['oauth_signature_method', 'HMAC-SHA1']);
message.parameters.push(['oauth_consumer_key', XXXXXXXXXXXXXXXX]);
message.parameters.push(['oauth_token', XXXXXXXXXXXXXXX]);
message.parameters.push(['callback', 'my_twitter_resp_handler']);
OAuth.completeRequest(message, accessor);
var parameterMap = OAuth.getParameterMap(message.parameters);
