IdentityServer4添加用户的方法及遇到的坑

一、添加用户

public ReturnResult Add(JObject jo)
        {
            var returnResult = new ReturnResult();
            string userId = jo.GetValue("Id").ToString();
            string account = jo.GetValue("Account").ToString();
            string password = jo.GetValue("Password").ToString();
            string token = jo.GetValue("TokenKey").ToString();
            using (var serviceProvider = BaseLogic.GetServiceProvider())
            {
                using (var scope = serviceProvider.GetRequiredService<IServiceScopeFactory>().CreateScope())
                {
                    var context = scope.ServiceProvider.GetService<ApplicationDbContext>();
                    var userMgr = scope.ServiceProvider.GetRequiredService<UserManager<ApplicationUser>>();

                    var userModel = userMgr.FindByNameAsync(account).Result;
                    if (userModel == null)
                    {
                        userModel = new ApplicationUser
                        {
                            Id = userId,
                            UserName = account
                        };
                        var result = userMgr.CreateAsync(userModel, password).Result;
                        if (!result.Succeeded)
                        {
                            throw new Exception(result.Errors.First().Description);
                        }
                        result = userMgr.AddClaimsAsync(userModel, new Claim[] { new Claim(JwtClaimTypes.Name, account), }).Result;
                        if (!result.Succeeded)
                        {
                            throw new Exception(result.Errors.First().Description);
                        }
                    }
                    else
                    {
                        userMgr.ResetPasswordAsync(userModel, token, password);
                    }
                }
            }
            returnResult.Success = true;
            returnResult.Message = "操作成功";
            return returnResult;
        }

二、删除用户

public ReturnResult Delete(JObject jo)
        {
            var returnResult = new ReturnResult();
            string account = jo.GetValue("Account").ToString();
            using (var serviceProvider = BaseLogic.GetServiceProvider())
            {
                using (var scope = serviceProvider.GetRequiredService<IServiceScopeFactory>().CreateScope())
                {
                    var context = scope.ServiceProvider.GetService<ApplicationDbContext>();
                    var userMgr = scope.ServiceProvider.GetRequiredService<UserManager<ApplicationUser>>();

                    var userModel = userMgr.FindByNameAsync(account).Result;
                    if (userModel != null)
                    {
                        var claim = userMgr.GetClaimsAsync(userModel);
                        if (claim.Result != null)
                        {
                            var deleteClaimsResult = userMgr.RemoveClaimsAsync(userModel, claim.Result);
                            if (!deleteClaimsResult.Result.Succeeded)
                            {
                                returnResult.Success = false;
                                returnResult.Message = string.Join(',', deleteClaimsResult.Result.Errors.ToList().Select(c => c.Description).ToList());
                            }
                        }
                        var deleteUserResult = userMgr.DeleteAsync(userModel);
                        if (!deleteUserResult.Result.Succeeded)
                        {
                            returnResult.Success = false;
                            returnResult.Message = string.Join(',', deleteUserResult.Result.Errors.ToList().Select(c => c.Description).ToList());
                        }
                    }
                }
            }
            returnResult.Success = true;
            returnResult.Message = "操作成功";
            return returnResult;
        }

三、遇到的坑坑坑坑（折腾了我一个多小时）

result = userMgr.AddClaimsAsync(userModel, new Claim[] { new Claim(JwtClaimTypes.Name, account), }).Result;

上面标红的：

JwtClaimTypes

虽然是引用的：IdentityModel，但不能在nuget直接添加这个引用，要添加IdentityServer4这个引用，添加了IdentityServer4就自动会有IdentityModel。
