Question

我正在使用asp.net授权在客户端使用Angular js登录，我需要让当前用户登录

我需要获得当前用户才能将所有操作保存到我的记录器表中，并且httpcontext.session.current为null，是否有另一种方法可以将已登录的用户保存在会话中，或通过其他方式随时获取它

public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider

Answer 1

您可以从@Configuration @ConditionalOnClass(name = Constants.DB2_PRESENCE_TOKEN_CLASS) @AutoConfigureAfter(value = { DataSourceAutoConfiguration.class}) @Slf4j public class Db2CustomPropertiesAutoConfiguration implements BeanPostProcessor { @Override public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException { log.debug("bean {}", bean); if (bean instanceof DataSourceProxy && ((DataSource) bean).getDriverClassName().equals("com.ibm.db2.jcc.DB2Driver")) { ((DataSource) bean).getDbProperties().put("clientDebugInfo", "XXX") } return bean; } @Override public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException { return bean; } }获取Api Controller中的当前登录用户，而无需像这样引用任何名称空间，

IPrincipal

您还可以从... var user = User; //<= "User" comes from System.Security.Principal.IPrincipal ...获得其他属性，例如

AuthenticationType
已通过身份验证
名称

根据此类用户的身份，

IPrincipal

编辑：

您可以使用var authType = User.Identity.AuthenticationType; var isAuthenticated = User.Identity.IsAuthenticated; var name = User.Identity.Name;之类的方法将自定义字段添加为对您的身份的声明，

GrantResourceOwnerCredentials

然后在Api控制器操作方法中，您可以获得类似的UserId，

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

oAuthIdentity.AddClaim(new Claim("UserId", user.Id));   //<= The UserId add here as claim
oAuthIdentity.AddClaim(new Claim("UserName", user.UserName));  //<= The UserName add here as claim

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

编辑1：

在这里，我从声明中获得了var userId = ((ClaimsIdentity)User.Identity).FindFirst("UserId"); var userName = ((ClaimsIdentity)User.Identity).FindFirst("UserName");和UserId。

并且通过angular js HTTP，您可以发送auth承载令牌，例如

UserName

通过在斜角使用上述代码，您的请求将通过Http为每个请求添加身份验证令牌

详细了解$http

编辑2：

在module.run(function($http) { $http.defaults.headers.common.Authorization = 'bearer TGAf8ViNUtzb9RP9OCBXHN4Ewm0dQbTMb6x4wJMgi4Wk8pq-QEQLIhp_W1A-9jQa7Rlqa60vsQ2ubbjUL0wGosEwaHFDlbdkQqXbOP_VlBJMxN2KnGQZnmvWZvpLPqMF-jpWzPDvBwtVHnh3AjLviPX0gPQjxZAC1ujIeB0p-QZ8yE1VCnLa8Xql01XDXlLVBCzk1UOqt_er-Gx6pL8SemayY8dqVVUgSZTYhcceLLuWQ-Cy3QATJmoJ41K-7ktAeUTz5H7V3ImlC_b8qnnN8sj7k7WRT51q27pUO4-bzJzkD4LGVvDUqaeAhBEqKyS9TkpMIFbRDMol5ZiJcp2vTunOOYP42Mw7GJv09ctoXegKkWo1LWDsSDxeWP5KQed_VGX193pZvQtvz06g2iyXwuP8Q6NaJcXTF43-M9p2HWgGuXT531YXv59euaWevj1AMJkazlZ61uzYi7KGLHKgCwzAMXLKwzBGK4QP0C4tqonowSdTttH93LBOJHjrDepk'; });中将您希望随身携带的这些数据添加到工作单元存储库中，例如，

GrantResourceOwnerCredentials

然后在控制器方法中读取这些数据，例如

oAuthIdentity.AddClaim(new Claim("Id", user.Id));
oAuthIdentity.AddClaim(new Claim("UserName", user.UserName));
oAuthIdentity.AddClaim(new Claim("Email", user.Email));
oAuthIdentity.AddClaim(new Claim("PhoneNumber", user.PhoneNumber));

现在，您可以随意使用该对象ClaimsPrincipal principal = Request.GetRequestContext().Principal as ClaimsPrincipal; var claims = principal.Claims.Select(x => new { type = x.Type, value = x.Value }); var id = claims.Where(x => x.type == "Id").FirstOrDefault().value; var userName = claims.Where(x => x.type == "UserName").FirstOrDefault().value; var email = claims.Where(x => x.type == "Email").FirstOrDefault().value; var phoneNumber = claims.Where(x => x.type == "PhoneNumber").FirstOrDefault().value; ApplicationUser applicationUser = new ApplicationUser //This model is pre generated by web api project and reside in `Models` folder { Id = id, UserName = userName, Email = email, PhoneNumber = phoneNumber };传入工作单元存储库。

查看此问题 Is it possible to set localStorage or Session variable in asp.net page and read it in javascript on the other page?

public  void SaveLog( T Obj, string Operation)
    {

        string hostName = Dns.GetHostName(); // Retrive the Name of HOST  IpAddress
        string myIP = Dns.GetHostEntry(hostName).AddressList[0].ToString();

        var user = HttpContext.Current.Session["user"] as View_Emps;

//代替此..您可以将其保存在本地存储中，并在注销或超时//计时器后将其删除

        MyLogger.Data =  new JavaScriptSerializer().Serialize(Obj);
        MyLogger.OperationType = Operation;
        MyLogger.TableName = typeof(T).Name;
        MyLogger.DateTime = DateTime.Now;
        MyLogger.User_ID = user.Emp_ID;
        MyLogger.IP_Address = myIP;
        db.Loggers.Add(MyLogger);
        Commit();


    }

Answer 3

var UserName = User.Identity.Name;
var UserId = ((ClaimsIdentity)User.Identity).Claims.FirstOrDefault().Value;

这种方式很好用，但是我不得不在标题中发送令牌

Answer 4

在 MVC 控制器中：

var user = await _userManager.GetUserAsync(User);

在 API 控制器中，使用这个：

var user = await _userManager.FindByNameAsync(User.Identity.Name);

确保用户在控制器和页面开头使用 authorize 属性经过身份验证：

[Authorize]

Answer 5

您无法在api调用中使用会话，每次您需要对用户进行身份验证时，都必须发送该用户的令牌

您可以阅读有关JWT进行身份验证的信息

有没有办法让Api Controller中的当前用户
