c# – OAuth令牌授权(请求已被拒绝)

启动：

public void Configuration(IAppBuilder app)
{
    HttpConfiguration httpConfig = new HttpConfiguration();
    ConfigureOAuthTokenGeneration(app);
    ConfigureOAuthTokenConsumption(app);
    ConfigureWebApi(httpConfig);
    app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
    app.UseWebApi(httpConfig);
}

CustomOAuthProvider：

public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
    var userManager = context.OwinContext.GetUserManager<UserManager>();
    User user = await userManager.FindAsync(context.UserName,context.Password);

    // checks with context.SetError() results.

    ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager,"JWT");
    oAuthIdentity.AddClaim(new Claim(ClaimTypes.Role,"User"));

    var ticket = new AuthenticationTicket(oAuthIdentity,null);
    context.Validated(ticket);
}

认为我从I get “Authorization has been denied for this request.” error message when using OWIN oAuth middleware (with separate Auth and Resource Server)开始尝试：

>将所有Owin软件包更新到最新版本(Web项目不使用任何Owin功能,因此不在此处安装).
> Api和Web是不同的项目,但在同一台机器上,所以同样的机器密钥.
> OAuth令牌配置在Startup.cs中的WebApi配置之前.
>声明：oAuthIdentity由角色和管理员声明组成(http://schemas.microsoft.com/ws/2008/06/identity/claims/role：用户)

其他一切都按预期工作(web api,cors,token generation,……),我做错了什么？ (涉及到很多代码,所以如果我需要从我的项目中添加其他代码,请告诉我.

编辑：

Ajax调用(jumuro解决方案)：

var token = sessionStorage.getItem(tokenKey); // Same as the generated login token
$.ajax({
    type: 'POST',// Don't forget the 'Bearer '!
    beforeSend: function (xhr) { xhr.setRequestHeader('Authorization','Bearer ' + token) },url: 'http://localhost:81/api/auth/test',// Authorized method
    contentType: 'application/json; charset=utf-8'
}).done(function (data) {
    //
});
