I figured out what's going on... For some reason, OAuth.NET isn't discovering when a resource is unprotected. I hacked OAuth.NET to allow the token lookup to be circumvented and to allow you to retrieve a resource without including an access token. I'll be uploading new dlls to http://code.google.com/p/nfapi/ shortly (new source code and hacked OAuth.NET DLLs are already there).
I'll have to look into it. I haven't implemented all of the functionality, just the basic catalog and queue stuff. The CatalogTitle object has a Synopsis link; I'd imagine a request to that link will return the information. I'll try calling that to see what comes back when you call it, and wrapping it in another function call if necessary.
hi shattered arm,
i use oauth. but when i send request_token i gives me invalid signature error everytime it gives me. can you please tell me what is doing wrong we are ? here i post my code
string str1 = "";
string str = "";
string consumerKey = "kwznqsw3kcwdgs6hdyepabzb";
string consumerSecret = "MGUpw4pvGP";
Uri uri = new Uri("http://api.netflix.com/oauth/request_token");
OAuthBase oAuth = new OAuthBase();
string nonce = oAuth.GenerateNonce();
string timeStamp = oAuth.GenerateTimeStamp();
string sig = oAuth.GenerateSignature(uri,
consumerKey, consumerSecret,
string.Empty, string.Empty,
"GET", timeStamp, nonce,
OAuthBase.SignatureTypes.HMACSHA1, out str, out str);
sig = HttpUtility.UrlEncode(sig);
string strsig = "HMAC-SHA1";
string strver = "1.0";
StringBuilder sb = new StringBuilder("GET&");
sb.AppendFormat(uri.ToString());
sb.AppendFormat("?oauth_consumer_key={0}&", consumerKey);
sb.AppendFormat("oauth_nonce={0}&", nonce);

sb.AppendFormat("oauth_signature_method={0}&", strsig);

hi,
i use your NFAPI dll but i got error on getting oauthservice "Could not find section 'oauth.net.consumer' in the configuration file associated with this domain."
hi,
now i am getting a request_token and go to step for user authorization here link for user authorization
https://api-user.netflix.com/oauth/login?oauth_consumer_key=key&applica
tion_name=filmjamr&oauth_token=h96us4j2t9xshmc27pjsuvn3&oauth_callback=http://filmjamr.com
now i want to know that what i get when it callback to this url if this gives access_token then in what form mean (in xml or a querystring) and when i get this access_token then how to get user_id
hi,
i am getting request_token and access_token but not getting userid because this function rq_OnReceiveAccessToken not fired how this is fired
here my code
private OAuthResource GetAccessKey(string uri, NameValueCollection parameters)
{
OAuthRequest rq = OAuthRequest.Create(
new Uri(uri),
_getService,
_requestToken,
_accessToken); // Create the request
rq.OnReceiveAccessToken +=new EventHandler<AccessTokenReceivedEventArgs>(rq_OnReceiveAccessToken);
OAuthResponse response = rq.GetResource(parameters); //get the response
if (response.HasProtectedResource)
{
return response.ProtectedResource;
}
else
{
_requestToken = response.Token; //if you got here, it means you only have the request token and need to direct the user to the login page.
I'm not familiar with this library, but you can also get the user resource URL by calling users/current, using the new access token for auth. See http://developer.netflix.com/blog/read/This_Weeks_API_Update_a_Note_on_Interfaces for more info.
ShatteredArm, I checked out your source using SVN and am trying to run your application EXACTLY as-is with no changes whatsoever. The ONLY thing I have edited is the App.config to include my values for apikey, secret, and applicationname. But I keep getting "The remote server returned an error: (401) Unauthorized." on line 242 in NetflixService.cs. Any advice?
anybody is there pls help.I have used Shattered Arm project but after getting Access token i m unable to get the userid.Will it be returned with the Access token or one more step i have to do to get userid ? i have already posted my code above please help me friends i m stuck how to get the user id .help......................................
hi michael i use the nfapi dll and code which provide by shattered arm but i am stuck when i am getting access_token it does not return userid i don't know but how i get userid

Pawan, I've got a wrapper around the API that you can use as is or as a sample for writing your own.
Hi Allen
Thanx For Provideing me the link and i have dowbloaded the files from http://www.codeplex.com/WrapNetflix/Release/ProjectReleases.aspx?ReleaseId=20682
but Allene when I m running it in by adding them in solution because the solution file is not there then it is giving me error for "My.Settings.ConsumerKey","My.Settings.ConsumerSecret" That they are not the member of "WindowsApplication1.My.setting".
Am i wrong some where?.pls if you can provide me any sample application or documentation for using this NetflixBinaries_0.4.
I'm working with Visual Studio 2008/Visual Basic and the oAuth.net library.
I'm having difficulty with the authentication token. My code sends the user to the authentication site with a well formed authentication request. The site then redirects (via the browser and a custom url handler) back to my application which catches the oAuth string as a StartupNextInstance argument.
My question: how do I store the returned oAuth string as a IToken? I cannot find a IToken class method that builds a IToken from a simple string. Sounds like a simple problem, but I'm stuck.
If I know a NetFlix subscriber's user id and password, how can I use your NFAPI API to create a NetflixService service to access protected data, such as, Queue?
I'm working on a WPF application and do not want the user going to NETFLIX login page and authorize the application in NETFLIX web page.

I figured out what's going on... For some reason, OAuth.NET isn't discovering when a resource is unprotected. I hacked OAuth.NET to allow the token lookup to be circumvented and to allow you to retrieve a resource without including an access token. I'll be uploading new dlls to http://code.google.com/p/nfapi/ shortly (new source code and hacked OAuth.NET DLLs are already there).

shatteredarm... how would you make a request for a title's synposis with your dll's? Assuming I already have the uri for the title's synposis
ShatteredArm – 4 years ago
I'll have to look into it. I haven't implemented all of the functionality, just the basic catalog and queue stuff. The CatalogTitle object has a Synopsis link; I'd imagine a request to that link will return the information. I'll try calling that to see what comes back when you call it, and wrapping it in another function call if necessary.
ShatteredArm – 4 years ago
Added synopsis. Just call CatalogDal.GetSynopsis with the CatalogTitle object (needs to have synopsis link set for it to work).

Jonathan Allen is also working on a .NET API. Maybe you should collaborate. See: http://developer.netflix.com/forum/read/31573.

hi,
i am getting request_token and access_token but not getting userid because this function rq_OnReceiveAccessToken not fired how this is fired
here my code
private OAuthResource GetAccessKey(string uri, NameValueCollection parameters)
{
OAuthRequest rq = OAuthRequest.Create(
new Uri(uri),
_getService,
_requestToken,
_accessToken); // Create the request
rq.OnReceiveAccessToken +=new EventHandler<AccessTokenReceivedEventArgs>(rq_OnReceiveAccessToken);
OAuthResponse response = rq.GetResource(parameters); //get the response
if (response.HasProtectedResource)
{
return response.ProtectedResource;
}
else
{
_requestToken = response.Token; //if you got here, it means you only have the request token and need to direct the user to the login page.
throw new OAuthNotAuthorizedException();
}
}
void rq_OnReceiveAccessToken(object sender, AccessTokenReceivedEventArgs e)
{
_accessToken = e.AccessToken;
_UserID = e.AdditionalParameters["user_id"];
OAuthRequest req = sender as OAuthRequest;
req.ResourceUri = new Uri(req.ResourceUri.AbsoluteUri.Replace("{userid}", _UserID)); //TODO
}
thanks & regards

I'm not familiar with this library, but you can also get the user resource URL by calling users/current, using the new access token for auth. See http://developer.netflix.com/blog/read/This_Weeks_API_Update_a_Note_on_Interfaces for more info.

ShatteredArm, I checked out your source using SVN and am trying to run your application EXACTLY as-is with no changes whatsoever. The ONLY thing I have edited is the App.config to include my values for apikey, secret, and applicationname. But I keep getting "The remote server returned an error: (401) Unauthorized." on line 242 in NetflixService.cs. Any advice?
Elfie – 3 years ago
ShatteredArm, nevermind! I had to delete the existing tokens file and that made it work perfectly.

Michael Hart – 3 years ago
Pawan, you might check out how some of the libraries on the resource page do this. I'm sure there is likely source available for some of them.

Pawan, I've got a wrapper around the API that you can use as is or as a sample for writing your own.

I'm working with Visual Studio 2008/Visual Basic and the oAuth.net library.
I'm having difficulty with the authentication token. My code sends the user to the authentication site with a well formed authentication request. The site then redirects (via the browser and a custom url handler) back to my application which catches the oAuth string as a StartupNextInstance argument.
My question: how do I store the returned oAuth string as a IToken? I cannot find a IToken class method that builds a IToken from a simple string. Sounds like a simple problem, but I'm stuck.
Thank you,

Hi ShatteredArm,
If I know a NetFlix subscriber's user id and password, how can I use your NFAPI API to create a NetflixService service to access protected data, such as, Queue? I'm working on a WPF application and do not want the user going to NETFLIX login page and authorize the application in NETFLIX web page.
