I am trying to connect to rackspace using their api and passing my username and api key but i get this error :
The remote server returned an error: (401) Unauthorized.
here is my code :
UserCredentials userCreds = new UserCredentials("myusername", "myapikey");
Connection connection = new Connection(userCreds);
I have followed this tutorial :
http://www.rackspace.com/knowledge_center/index.php/Sample_CSharp_Application
have asked their support and they say we can connect with same key using curl...and they couldnt provide much help.
anyone has any idea?
thanks
for anyone else who got same problem here i found the solution, you basically need to include the api uri :
http://blog.chmouel.com/2011/01/04/how-to-use-the-rackspace-cloud-uk-api/
Your sample works but I was looking for a direct way, without the wrapper. This seems to work as well, and uses direct restful access to the Rackspace API.
Hope it helps. Cheers.
string url = "https://auth.api.rackspacecloud.com/v1.0";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Headers.Add("X-Auth-User:" + userName);
request.Headers.Add("X-Auth-Key:" + apiKey);
request.Method = "GET";
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
string[] keys = response.Headers.AllKeys;
foreach (var k in keys)
Console.WriteLine(response.Headers[k]);
}

Am using WebRequest to validate Url before saving it to Db, But for some url's am getting 403 forbidden error. Please suggest me how can i resolve this issue or any alternate way for this.
i have used code like below.
var webRequest = WebRequest.Create(url);
var webResponse = webRequest.GetResponse();
i also tried WebClient in local its working but when we deploy its throwing same error. Please find the WebClient code aswell
using (WebClient webClient = new WebClient())
{
webClient.Headers.Add("user-agent", "test");
string content = webClient.DownloadString(url);
}
The main purpose we are used this to check when user enters any url attacks.. Please suggent if any way to resolve this
I get following error: "The remote server returned an error: (401) Unauthorized" in this line:
using (HttpWebResponse httpResponse = request.GetResponse() as HttpWebResponse) {}
Here is the complete code:
string clientSecretKey = ConfigurationManager.AppSettings["ClientSecretKey"];
const string ChargeUrl = "https://api.stripe.com/v1/charges?amount={0}¤cy={1}&source={2}&description={3}";
string requestUrl = HttpUtility.UrlPathEncode(
String.Format(ChargeUrl, 1000, "usd", "tok_19xLu8HN9aKw9vrkUsflNWOI", "Test charge to text#example.com") );
HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
request.Headers.Add("Authorization", "sk_test_example");
request.ContentType = "application/x-www-form-urlencoded";
request.Method = "POST";
using (HttpWebResponse httpResponse = request.GetResponse() as HttpWebResponse)
{/* some code */}
At the beginning I thought the error was caused because the token can't used more than one time, but I changed it and got the same error. I'm not sure what is causing the error.
The issue here is that you are passing the API key but not using Bearer authentication which is what Stripe's API expects. You need to change your Authorization header like this:
request.Headers.Add("Authorization", "Bearer sk_test_example");
I know you mentioned in the comments that you can't use a third-party library but I wanted to mention one just in case. Stripe.net lets you use Stripe's API in .Net easily without having to rewrite the logic yourself. Handling errors, encoding parameters and sub-hashes properly, managing authentication and JSON decoding, all of this will take a lot of time and trial and error to build from scratch while this library would handle all of this for you.
You're initializing a variable for the secret key but not using it. Try modifying the request url to start with "https://" + clientSecretKey + ":#api..."
This is, of course, assuming clientSecretKey is the Stripe key.
Be careful putting a secret key somewhere on your server that it isn't hidden from a user / client.
I'm hoping I've done something knuckle-headed here and there is an easy answer. I'm simply trying to retrieve the list of comments for a page on my site. I use the social plug-in and then retrieve the comment id via the edge event. Server side I send the page id back and do a simple request using a HttpWebRequest. Worked well back in October, but now I get an 'internal error' response from FB. I can use the same url string put it into a browser and get the comments back in the browser in json.
StringBuilder url = new StringBuilder();
url.Append("https://graph.facebook.com/comments/?ids=" + comment.page);
string requestString = url.ToString();
HttpWebRequest request = WebRequest.Create(requestString) as HttpWebRequest;
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
Ideas? Thanks much in advance.
Since you're using the Facebook C# SDK (per your tag), try:
var url = "{your url}";
var api = new Facebook.FacebookClient(appId,appSec);
dynamic commentsObj = api.Get("/comments/?ids=" + url);
dynamic arrayOfComments = commentsObj[url].data
I'm writing a .NET app that runs on a Windows computer. It is not accessible through the browser. The problem is, I can't authenticate like I should. I'm currently coding in C# .NET, more specific in C#.
I have a webbrowser control on my form.
The user logs on to facebook through this webbrowser control.
After the logon, I start the authentication procedure.
I then retreive a code.
Here's where it goes wrong. With this code I want to obtain an access token.
The generated request URL looks like: https://graph.facebook.com/oauth/access_token?client_id=____MY_APP_ID______&redirect_uri=http://localhost/&client_secret=_____MY_APP_SECRET_____&code=____MY_RETREIVED_CODE_____ and is made through the code below.
Please note that my redirect URL is http://localhost. This should be okay, right?
Also, in my App Settings, I have the following information.
Site URL: http://localhost/
Site Domain: localhost
private String ExchangeCodeForToken(String code, Uri redirectUrl)
{
var TokenEndpoint = new Uri("https://graph.facebook.com/oauth/access_token");
var url = TokenEndpoint + "?" +
"client_id=" + _AppID + "&" +
"redirect_uri=" + redirectUrl + "&" +
"client_secret=" + _AppSecret + "&" +
"code=" + code;
var request = WebRequest.CreateDefault(new Uri(url));
using (var response = request.GetResponse())
{
using (var responseStream = response.GetResponseStream())
{
using (var responseReader = new StreamReader(responseStream))
{
var responseText = responseReader.ReadToEnd();
var token = responseText.Replace("access_token=", "");
return token;
}
}
}
}
When I execute this, I get this error:
error http://www.imageupload.org/getfile.php?id=50131&a=447f6fcc0ebd4d3f8e8a59a3a6e36ac3&t=4de0841c&o=0889D68FDC35508BA2C6F2689FCBAB7C30A8670CC9647EE598701D8BEC13ED278F0989D393&n=autherror.png&i=1
Webexception was unhandled by user code
The remote server returned an error: (400) Bad Request.
Here's where I think I might be going wrong:
Are my app settings correct?
Should my redirect url be http://localhost, even if there isn't actually a service listening there?
Most importantly:
how do I get rid of this error and retreive the access token?
Thanks in advance!
You get this error because you are not supposed to call this URL from a Desktop app : as far as I know, you can not use the token endpoint for Desktop app authentication. Also, you can get the access token directly (no need to ask for a code first). Here is what you have to do.
Load the following URL in your embedded web browser :
https://www.facebook.com/dialog/oauth?
client_id=YOUR_APP_ID&
redirect_uri=https://www.facebook.com/connect/login_success.html
The user will be asked to log in and will be redirected to this URL with the access token in the URL :
https://www.facebook.com/connect/login_success.html#access_token=...
So you have to detect the redirect and retrieve the access token from the URL.
Thanks quinten!
However, I've managed to solve my own problem by using the C# Facebook SDK.
This software development kit has been a really great help!
There are a lot of samples included (including authorisation)
Anyone who programs in .NET with facebook should check it out! Coding for facebook is now much easier.

I'm attempting to use Fogbugz's BugzScout in order to automatically submit unhanded application exceptions to my Fogbugz on demand Account. I've written up a wrapper class for it and everything appears to be just groovy - on my box. Testing the same code in the production environment, behind a Proxy that requires authentication, I have had nothing but issues.
I went to work modifying the BugzScout code in order to get it to authenticate with the Proxy, and after trying many different methods suggested via a Google search, found one that works! But now I'm getting an "Connection actively refused" error from Fogbugz itself, and I don't know what to do.
Here is the code where the BugzScout connects via a .net WebClient to submit a new case, with my modifications to deal with our Proxy. What am I doing that would cause Fogbugz to refuse my request? I've removed all non web-client related code from the procedure for ease of reading.
public string Submit(){
WebClient client = new WebClient();
WebProxy proxy = new WebProxy();
proxy.UseDefaultCredentials = true;
client.Proxy = proxy;
Byte[] response = client.DownloadData(fogBugzUrl);
string responseText = System.Text.Encoding.UTF8.GetString(response);
return (responseText == "") ? this.defaultMsg : responseText;
}
The url is correct and the case is filled in properly- this has been verified.
EDIT: Additional info.
Using Fogbugz on Demand.
Using FogBugz.net code in it's entirety, with only these additions
WebProxy proxy = new WebProxy();
proxy.UseDefaultCredentials = true;
client.Proxy = proxy;
Error occurs when attempting to connect to both https://oursite.fogbugz.com/scoutsubmit.asp and http://oursite.fogbugz.com//scoutsubmit.asp (except one says port 443, and the other port 80, obviously)
I don't know anything about web authentication so I can't tell you what kind I'm using- if you tell me where to look I'd be happy to answer that for you.
Got the fix from Fogbugz- this is the appropriate network code to get though the proxy authentication and not mis-authenticate with Bugzscout.
WebRequest.DefaultWebProxy.Credentials = CredentialCache.DefaultNetworkCredentials;
WebRequest request = WebRequest.Create(fogBugzUrl);
request.ContentType = "application/x-www-form-urlencoded";
request.Method = "POST";
request.Proxy.Credentials = CredentialCache.DefaultNetworkCredentials;
Stream requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
Is your fogbugzUrl using HTTP Basic Authentication? Is it SSL (hosted on On Demand?)
The connection actively refused message would be coming from the web server itself, not really FogBugz.
Can you post the HTTP Status Code?
One thing to note if you are using FogBugz On Demand is you HAVE to use the https:// url (not the http url).
