发送REST请求时如何从ASP.NET标识获取用户ID

我相信您希望在/token的响应中使用userid。

默认情况下,标识不会在响应中添加userid。

因此,您需要在方法的applicationOAuthProvider.cs中手动添加它。 GrantResourceOwnerCredentials

public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
        {
            var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();

            ApplicationUser user = await userManager.FindAsync(context.UserName, context.Password);

            if (user == null)
            {
                context.SetError("invalid_grant", "The user name or password is incorrect.");
                return;
            }

            ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager,
               OAuthDefaults.AuthenticationType);
            ClaimsIdentity cookiesIdentity = await user.GenerateUserIdentityAsync(userManager,
                CookieAuthenticationDefaults.AuthenticationType);

            AuthenticationProperties properties = CreateProperties(user.UserName);


            AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
            ticket.Properties.Dictionary.Add("UserId", user.Id);


            context.Validated(ticket);
            context.Request.Context.Authentication.SignIn(cookiesIdentity);
        }
