I am writing some C# code to perform multiple commits to SVN in one pass, much like the tool svnmucc. So far I've been using SharpSvn to do the rest of the necessary communication with SVN, so I'm thinking I can take advantage of it to accomplish the following:
How can I get the credentials (username, password) that are used by SharpSvn?
I'd like to do something like this:
using (SvnClient svnClient = new SvnClient())
{
SomeFictitiousCredentialsClass credentials = svnClient.Authentication.FictitiousGetCachedCredentialsMethod();
// Call my code that performs svnmucc-like work here, passing username and password
// obtained from 'credentials' variable.
}
Sharpsvn doesn't have an api that provides you the credentials from Subversion. It mostly implements the libsvn_client api, and at this level there is no access to this data.
SharpSvn gets a callback from the subversion libraries when these need credentials; in most cases after the builtin password store fails to authenticate.
If your svnmucc code also uses the Subversion apis, you can just plugin the subversion predefined authentication handlers..
SharpSvn itself doesn't have svnmucc support yet. (There was some talk about somebody who liked to add this to SharpSvn, but I haven't got any news about this lately)
While the other answer is still valid for all current versions of SharpSvn, SvnMucc support has just landed in the development code for SharpSvn. So soon it will be possible to perform SvnMucc like operations from .Net.
using SharpSvn;
SvnCommitResult cr;
using (SvnMultiCommandClient mucc = new SvnMultiCommandClient("http://my-repos/svn/"))
{
mucc.CreateDirectory("trunk");
mucc.CreateDirectory("branches");
mucc.CreateDirectory("tags");
mucc.CreateDirectory("trunk/src");
mucc.SetProperty("", "svn:auto-props", "*.cs = svn:eol-style=native");
mucc.SetProperty("", "svn:global-ignores", "bin obj");
mucc.Commit(out cr); // Commit r1
}
using (SvnClient client = new SvnClient())
{
client.CheckOut("http://my-repos/svn/", #"C:\wc");
}
There is a slightly different syntax available if you would like to perform the operation from an existing SvnClient, but this is the general idea.

I want to download release asset zipball´s in a C# application for further use.
I´m using Octokit to get all release informations from the repo, including the respective browserdownload_url.
After some research it seemed to me, that you cant download this release asset zip´s via octokit, so trying with httpclient as suggested by some SO posts, that were asking these questions.
The release zip´s are on a Github Enterprise Repository, so they require Authentication.
And that is probably my issue, i cant make the authentication work with the httpClient...
The request always responds with Code 404
(which is the regular behaviour if you try by putting the url into the regular browser without logging in)
My actual implementation looks like this
public void DownloadRelease(string dlUrl, string targetPath)
{
var githubToken = "aaaaaaaaaaabbbbbbbbbcccccccccdddddddddd"; //Token created in the github developer settings with all available rights
//dlUrl = https://github.server.de/organization/project/releases/download/v1.2.34/release.zip
using (var client = new System.Net.Http.HttpClient())
{
var credentials = string.Format(System.Globalization.CultureInfo.InvariantCulture, "{0}:", githubToken);
credentials = Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes(credentials));
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", credentials);
//client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", githubToken);
var contents = client.GetByteArrayAsync(dlUrl).Result;
System.IO.File.WriteAllBytes(targetPath, contents);
}
}
Update:
At the End we followed the way of using the curl way:
https://docs.github.com/en/enterprise-server#3.0/rest/reference/repos#download-a-repository-archive-zip
And one more mistake on my end: There were releases without downloadable Asset IDs which i didnt catch in the code.
Based on the documentation (https://docs.github.com/en/enterprise-server#2.22/rest/overview/other-authentication-methods#via-oauth-and-personal-access-tokens) my best guess is, that your crendentials are wrong.
The docs say, the format should be username:token, yet you are only using token followed by a colon : - that doesn't look right to me, either.
So essentially you need to refactor your credentials variable a bit:
var credentials = $"{username}:{githubToken}";
If I have the following code:
var token = System.Security.Principal.WindowsIdentity.GetCurrent();
I get a WindowsIdentity that is Kerberos based. I need to make a call with a header like this:
Authorize: Negotiate <Kerberos Token Here>
Is there a way to convert that token object into a Base64 string?
As the maintainer of the Kerberos.NET as mentioned in the other answer, you can always go that route. However, if you want SSO using the currently signed in Windows identity you have to go through Windows' SSPI stack.
Many .NET clients already support this natively using Windows Integrated auth, its just a matter of finding the correct knobs. It's unclear what client you're using so I can't offer any suggestions beyond that.
However if this is a custom client you have to call into SSPI directly. There's a handful of really good answers for explaining how to do that such as: Client-server authentication - using SSPI?.
The aforementioned Kerberos.NET library does have a small wrapper around SSPI: https://github.com/dotnet/Kerberos.NET/blob/develop/Kerberos.NET/Win32/SspiContext.cs
It's pretty trivial:
using (var context = new SspiContext($"host/yourremoteserver.com", "Negotiate"))
{
var tokenBytes = context.RequestToken();
var header = "Negotiate " + Convert.ToBase64String(tokenBytes);
...
}
I could not get this to work, but I was able to get a token using the excellent Kerberos.NET NuGet package. With that I was able to get it like this:
var client = new KerberosClient();
var kerbCred = new KerberosPasswordCredential("UserName", "p#ssword", "domain");
await client.Authenticate(kerbCred);
Console.WriteLine(client.UserPrincipalName);
var ticket = await client.GetServiceTicket("http/ServerThatWantsTheKerberosTicket.domain.net");
return Convert.ToBase64String(ticket.EncodeGssApi().ToArray());
As an aside, I needed help figuring out what the SPN value was for the GetServiceTicket and the project maintainer was fantastically helpful (and fast!).
I'm usinng skybrud social to allow users to log into my site via Facebook, but am having a problem.
For some reason, the response never contains anything other than the Name and Id of the user... everything else is null.
var url = client.GetAuthorizationUrl(state, "public_profile", "email");
var service = FacebookService.CreateFromAccessToken(userAccessToken);
FacebookMeResponse user = service.Methods.Me();
Has anyone experienced this before? What could be the problem?
Facebook has multiple versions of their Graph API. In the most recent version (2.4), less fields are returned by default, and you instead have to tell the API to return the fields that you need. What version of the API you're using depends on the time you registered your app with Facebook.
Based on your code, it seems that you're using an older version of Skybrud.Social. If you update to the most recent version (0.9.4.1), you can do something like this:
// Declare the options for the call to the API
FacebookGetUserOptions options = new FacebookGetUserOptions("me") {
Fields = "name,email,gender"
};
// Make the call to the API
FacebookUserResponse response = service.Users.GetUser(options);
Hope this answers your questions ;)
I am trying to add a Virtual Directory to an Azure Web Site from a WinForms Application using the Azure API. I can enumerate the WebSites on in my webspace, but I cannot find a method that allows me access to the Virtual Directories in the WebSite.
Here is my code:
string certPath = Properties.Settings.Default.AzureCertificatePath;
string certPassword = Properties.Settings.Default.AzureCertificatePassword;
string subscriptionId = Properties.Settings.Default.AzureSubscriptionId;
var cert = new X509Certificate2(certPath, certPassword, X509KeyStorageFlags.MachineKeySet);
var cred = new CertificateCloudCredentials(subscriptionId, cert);
using (var client = new WebSiteManagementClient(cred))
{
var spaces = client.WebSpaces.List();
foreach (var space in spaces)
{
Console.WriteLine("Space: {0}", space.Name);
var sites = client.WebSpaces.ListWebSites(space.Name, new WebSiteListParameters {PropertiesToInclude = { "Name" } }); ***// Where do I find out what properties can be included in this array?***
foreach (var site in sites)
{
***// What goes here to show the virtual directories in this specific website??????***
}
}
}
I found that the Azure web services API does not offer access to the virtual directories/applications on a web app, although the underlying REST API's that it uses does.
Luckily, the management API is open source (I wanted to get the v3.0.0.0 of the website management API, matching what I had NuGet'd, which I found here: https://github.com/Azure/azure-sdk-for-net/commits/master?page=79) so with a little perseverance and messing about with .targets files and NuGet references, you can get the source code of the WebSiteManagement project into your solution instead of the referenced DLL that you likely downloaded from NuGet.
From there, if you go into your client.WebSites.GetConfiguration method, stick a breakpoint in and capture the HTTP response returned - you'll see that in the JSON the VirtualApplications on your website are indeed there.
From there, you can edit your copy of the source code to expose those object structures out, much the same way that other object structures are mapped out of the JSON (e.g. HandlerMappings).
Likewise for updating them, you need to add the VirtualApplications (in the ewact same format) into the Microsoft.WindowsAzure.Management.WebSites.Models.WebSiteUpdateConfigurationParameters, and pass that into client.WebSites.UpdateConfiguration (which you will also need to amend to map your VirtualApplications object structure back into JSON in the same format).
Works great for me doing it this way.
Note/Disclaimer: The GitHub site documentation does mention that much of the source code was autogenerated, and that you shouldn't really go editing that code, instead raise an issue on the project about getting it sorted. I didn't have the time to do this and needed an immediate way of getting it working with my local copy of the code only, so my solution does, as you'll note when you look a the source, involve adding to that auto-gen'd code. It works great, but I should in good conscience point you to the project owner's warnings about tinkering with the auto-gen'd code.
Anybody know where I can find a simple example C# code example? Apparently really tough to find.
I'm just starting out, got my Developer key.
Initial (really noob question/presumption) - -Can (should/must) my solution be a web service client? No new libraries I need to install in .Net right?
Basically, as a test, I want to be able to securely present a single note from a private notebook in html similar to what the Everfort export in html looks like on a outside WebSite.
Many Thanks in Advance!
You should start by downloading our API ZIP from http://www.evernote.com/about/developer/api/. You'll find C# client sample code in /sample/csharp. This sample code demonstrates using the Evernote API from a desktop application that authenticates using username and password.
I am not sure if you ever got this working, but I was playing around with Evernote, OpenAuth and C# this morning and managed to get it all working. I have put together a blog post / library explaining the experience and outlining how to do it with MVC here - http://www.shaunmccarthy.com/evernote-oauth-csharp/ - it uses the AsyncOAuth library: https://github.com/neuecc/AsyncOAuth
I wrote a wrapper around AsyncOAuth that you might find useful here: https://github.com/shaunmccarthy/AsyncOAuth.Evernote.Simple
One prickly thing to be aware of - the Evernote Endpoints (/oauth and /OAuth.action) are case sensitive
// Download the library from https://github.com/shaunmccarthy/AsyncOAuth.Evernote.Simple
// Configure the Authorizer with the URL of the Evernote service,
// your key, and your secret.
var EvernoteAuthorizer = new EvernoteAuthorizer(
"https://sandbox.evernote.com",
"slyrp-1234", // Not my real id / secret :)
"7acafe123456badb123");
// First of all, get a request token from Evernote - this causes a
// webrequest from your server to Evernote.
// The callBackUrl is the URL you want the user to return to once
// they validate the app
var requestToken = EvernoteAuthorizer.GetRequestToken(callBackUrl);
// Persist this token, as we are going to redirect the user to
// Evernote to Authorize this app
Session["RequestToken"] = requestToken;
// Generate the Evernote URL that we will redirect the user to in
// order to
var callForwardUrl = EvernoteAuthorizer.BuildAuthorizeUrl(requestToken);
// Redirect the user (e.g. MVC)
return Redirect(callForwardUrl);
// ... Once the user authroizes the app, they get redirected to callBackUrl
// where we parse the request parameter oauth_validator and finally get
// our credentials
// null = they didn't authorize us
var credentials = EvernoteAuthorizer.ParseAccessToken(
Request.QueryString["oauth_verifier"],
Session["RequestToken"] as RequestToken);
// Example of how to use the credential with Evernote SDK
var noteStoreUrl = EvernoteCredentials.NotebookUrl;
var noteStoreTransport = new THttpClient(new Uri(noteStoreUrl));
var noteStoreProtocol = new TBinaryProtocol(noteStoreTransport);
var noteStore = new NoteStore.Client(noteStoreProtocol);
List<Notebook> notebooks = client.listNotebooks(EvernoteCredentials.AuthToken);
http://weblogs.asp.net/psteele/archive/2010/08/06/edamlibrary-evernote-library-for-c.aspx might help. As the author states it just bundles some and fixes some. Haven't tried it myself but thought I'd mention for a possibly easier way to get started. Possibly.
This might help too...found it using the Way Back Machine since the original blog site was offline.
