与ASP身份2向/令牌端点时，一定要接受“invalid_client”错误 [英] Always receiving 'invalid_client' error when POSTing to /Token endpoint with ASP Identity 2

问题描述

大约一​​个月前，我做了一个项目，ASP身份OAuth的工作完美。我会发送POST请求到/令牌端点grant_type，用户名和密码，一切都是花花公子。

About a month ago I had a project working perfectly with ASP Identity OAuth. I'd send a POST request to the /Token endpoint with grant_type, username, and password, and all was dandy.

最近，我开始了基础的Visual Studio 2013 RC2的SPA模板的新项目。它比旧模板有点不同。身份验证设置为pretty基本默认值，

I recently started a new project based off of Visual Studio 2013 RC2's SPA template. It's a bit different than the old template. Authentication is set up to pretty basic defaults,

OAuthOptions = new OAuthAuthorizationServerOptions
{
    TokenEndpointPath = new PathString("/Token"),
    //AuthorizeEndpointPath = new PathString("/Account/Authorize"), 
    Provider = new ApplicationOAuthProvider(PublicClientId),
    AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
    AllowInsecureHttp = true
};

没有显著从默认模板修改。

Nothing significant changed from the default template. I can register accounts successfully through a Web API controller method I have implemented;

    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    public async Task<IHttpActionResult> Register(RegisterBindingModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new TunrUser() { UserName = model.Email, Email = model.Email, DisplayName = model.DisplayName };
            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                return Created(new Uri("/api/Users/" + user.Id,UriKind.Relative), user.toViewModel());
            }
            else
            {
                return BadRequest(result.Errors.First());
            }
        }
        return BadRequest(ModelState);
    }

不过，无论怎样我发布到/令牌终点，我的总是的获得同样的反应。

{"error":"invalid_client"}

通常我通过以下请求主体

Normally I pass the following request body

grant_type=password&username=user%40domain.com&password=userpassword

但是，这将导致同样的错误。这个工作在previous VS2013 SPA模板/身份。什么改变？

But this results in the same error. This worked in the previous VS2013 SPA template / Identity. What's changed?

感谢您！

推荐答案

因此​​，原来，新模板不包括ApplicationOAuthProvider的功能实现，在旧模板present。

So it turns out that the new templates don't include a functional implementation of ApplicationOAuthProvider that was present in the older templates.

此版本谈话之后，我进一步调查后发现， ApplicationOAuthProvider的工作实施提供这个包的NuGet ！它非常类似于旧的实现。

After watching this build talk, I investigated further and found that a working implementation of ApplicationOAuthProvider is available to check out in this NuGet package! It's very similar to the old implementation.
