本文介绍了我的ASP.NET Core Web API中的User.Identity.Name为空的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经在一个具有一个数据库的项目中添加了ASP.NET Core身份和Identity Server4，并且我想在所有其他项目中使用我的Identity Server.
I have added ASP.NET Core identity and Identity Server4 in one project with one database, and I want to use my Identity Server in all other project.
IdentityServer4启动类
IdentityServer4 Startup Class
public class Startup
{
public IConfigurationRoot Config { get; set; }
public Startup(IConfiguration configuration)
{
Config = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", false)
.Build();
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
IdentityModelEventSource.ShowPII = true;
//=== Identity Config ===
string ConnectionString = Config.GetSection("AppSettings:DefaultConnection").Value;
var migrationAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;
//-----------------------------------------------------------------
services.AddDbContext<MyIdentityDbContext>(options =>
options.UseSqlServer(ConnectionString, sql => sql.MigrationsAssembly(migrationAssembly)));
//-----------------------------------------------------------------
services.AddIdentity<MyIdentityUser, IdentityRole>(op =>
{
op.Password.RequireDigit = false;
op.Password.RequiredLength = 6;
op.Password.RequireUppercase = false;
op.Password.RequireLowercase = false;
op.Password.RequireNonAlphanumeric = false;
})
.AddEntityFrameworkStores<MyIdentityDbContext>()
.AddDefaultTokenProviders();
//=== IdentityServer4 config ===
services.AddIdentityServer(options =>
{
options.Events.RaiseErrorEvents = true;
options.Events.RaiseInformationEvents = true;
options.Events.RaiseFailureEvents = true;
options.Events.RaiseSuccessEvents = true;
})
.AddDeveloperSigningCredential()
.AddConfigurationStore(options =>
{
options.ConfigureDbContext = b => b.UseSqlServer(ConnectionString, sql => sql.MigrationsAssembly(migrationAssembly));
})
.AddOperationalStore(options =>
{
options.ConfigureDbContext = b => b.UseSqlServer(ConnectionString, sql => sql.MigrationsAssembly(migrationAssembly));
})
.AddAspNetIdentity<MyIdentityUser>();
services.AddMvc(options => options.EnableEndpointRouting = false);
services.AddAuthorization();
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseAuthentication();
app.UseRouting();
app.UseAuthorization();
app.UseIdentityServer();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
我为我的身份数据库添加种子的配置类:
My config class that I have seed my identity database with that:
public class Config
{
public static IEnumerable<IdentityResource> GetIdentityResources()
{
return new List<IdentityResource>
{
new IdentityResources.OpenId(),
new IdentityResources.Email(),
new IdentityResources.Profile(),
};
}
public static IEnumerable<ApiResource> GetApis()
{
return new List<ApiResource>
{
new ApiResource("MyAPI", "My asp.net core web api"),
};
}
public static IEnumerable<Client> GetClients()
{
return new List<Client>
{
new Client()
{
ClientId = "MyAndroidApp",
ClientName = "My Application for Android",
AllowedGrantTypes = GrantTypes.ResourceOwnerPassword,
ClientSecrets =
{
new Secret("secret".Sha256())
},
AllowedScopes=
{
IdentityServerConstants.StandardScopes.OpenId,
IdentityServerConstants.StandardScopes.Profile,
IdentityServerConstants.StandardScopes.Email,
IdentityServerConstants.StandardScopes.Address,
"MyAPI"
},
},
};
}
}
我已经在我的IdentityServer4& Identity项目的用户控制器中以以下操作方法注册了具有Admin角色的用户
I have register a user with role Admin with below action method in User controller in my IdentityServer4&Identity project
[HttpPost]
public async Task<IActionResult> Post([FromBody]SignUpModel model)
{
MydentityUser NewUser = new MydentityUser ()
{
UserName = model.UserName,
};
IdentityResult result = await UserManager.CreateAsync(NewUser, model.Password);
if (result.Succeeded)
{
if (!RoleManager.RoleExistsAsync("Admin").Result)
{
IdentityResult r = RoleManager.CreateAsync(new IdentityRole("Admin")).Result;
r = RoleManager.CreateAsync(new IdentityRole("Member")).Result;
r = RoleManager.CreateAsync(new IdentityRole("Guest")).Result;
}
result = await UserManager.AddToRoleAsync(NewUser, "Admin");
if (result.Succeeded)
{
List<Claim> UserClaims = new List<Claim>() {
new Claim("userName", NewUser.UserName),
new Claim(JwtClaimTypes.Role, "Admin"),
};
result = await UserManager.AddClaimsAsync(NewUser, UserClaims.ToArray());
return Ok("Registered");
}
}
}
现在我有另一个ASP.NET Web API项目，我想在我的android应用程序中使用此api.
Now I have another ASP.NET Web API project that I want to use this api in my android application.
我的创业班
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(IdentityServerAuthenticationDefaults.AuthenticationScheme)
.AddJwtBearer(options =>
{
options.Authority = "https://identity.mywebsite.ir";
options.RequireHttpsMetadata = false;
options.Audience = "MyAPI";
});
//I used below but not work too
//.AddIdentityServerAuthentication(options =>
//{
// options.Authority = "https://identity.mywebsite.ir";
// options.RequireHttpsMetadata = false;
// options.ApiName = "MyAPI";
// options.NameClaimType = ClaimTypes.Name;
// options.RoleClaimType = ClaimTypes.Role;
//});
services.AddOptions();
string cs = Configuration["AppSettings:DefaultConnection"];
services.AddDbContext<MyApiContext>(options =>
{
options.UseSqlServer(cs,
sqlServerOptions =>
{
sqlServerOptions.MigrationsAssembly("MyApi.Database");
});
});
services.AddControllers();
services.AddCors(options =>
{
options.AddPolicy("default", policy =>
{
policy.WithOrigins("*")
.AllowAnyHeader()
.AllowAnyMethod();
});
});
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseRouting();
app.UseCors("default");
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
我的问题是，当我在另一个项目中使用带有ASP.NET Core Identity的用户身份验证时，如何在Webapi中找到userId，
My Problem is how can I find userId in my Webapi when I have used user authentication with ASP.NET Core Identity in another project,
在我的两个项目(我的webapi和identityserver& identity项目)中，我有以下操作方法.我已经从/connect/token地址从android应用程序获取了令牌，并随请求发送了访问令牌.
I have below action method in my two project (my webapi and identityserver & identity project). I have get token from android application from /connect/token address and I send access token with my request.
public class TestController : ControllerBase
{
public async Task<IActionResult> Index()
{
string message = "";
if (User.Identity.IsAuthenticated)
{
message += "You are Registered ";
}
else
{
message += "You are not Registered ";
}
if (string.IsNullOrWhiteSpace(User.Identity.Name))
{
message += "UserId is null";
}
else
{
message += "UserId is not null";
}
return Ok(message);
}
}
我收到此消息:
您尚未注册UserId为空
You are not registered UserId is null
如何在我的WebAPI中访问我的UserId?为什么User.Identity.Name为null?为什么User.Identity.Claims.Count 0?
How can I access to my UserId in my WebAPI? Why User.Identity.Name is null? Why is User.Identity.Claims.Count 0?
修改
我已经在jwt.io网站中输入了访问令牌，这是输出
I have entered the access token in jwt.io website, this is the output
{
"nbf": 1587133648,
"exp": 1587137248,
"iss": "https://identity.mywebsite.ir",
"aud": "MyAPI",
"client_id": "MyAndroidApp",
"sub": "7e904278-78cc-46a8-9943-51dfeb360d8e",// I want this in my api but i get null
"auth_time": 1587133648,
"idp": "local",
"scope": [
"openid",
"MyAPI"
],
"amr": [
"pwd"
]
}
MyApi启动类
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = IdentityServerAuthenticationDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = "oidc";
})
.AddIdentityServerAuthentication(options =>
{
options.Authority = "https://identity.mywebsite.ir";
options.RequireHttpsMetadata = false;
options.ApiName = "MyAPI";
});
services.AddOptions();
string cs = Configuration["AppSettings:DefaultConnection"];
services.AddDbContext<MyCommonDbContext>(options =>
{
options.UseSqlServer(cs,
sqlServerOptions =>
{
sqlServerOptions.MigrationsAssembly("MyAppProjectName");
});
});
services.AddDbContext<MyAppContext>(options =>
{
options.UseSqlServer(cs,
sqlServerOptions =>
{
sqlServerOptions.MigrationsAssembly("MyAppProjectName");
});
});
services.AddControllers();
services.AddCors(options =>
{
options.AddPolicy("default", policy =>
{
policy.WithOrigins("http://*.mywebsite.ir")
.AllowAnyHeader()
.AllowAnyMethod();
});
});
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseRouting();
app.UseCors("default");
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
推荐答案
在我的情况下，问题是我没有向ApiResources添加UserClaims，所以我像下面那样更改了种子ApiResource方法，并添加了声明，
In my case the problem was for that I did not add UserClaims to ApiResources so I changed the seeding ApiResource method like below and I added the the claims,
public static IEnumerable<ApiResource> GetApis()
{
return new List<ApiResource>
{
new ApiResource("MyAPI", "My Asp.net core WebApi,the best Webapi!"){
UserClaims =
{
JwtClaimTypes.Name,
JwtClaimTypes.Subject,
JwtClaimTypes.Role,
}
},
};
}
现在，我将使用以下代码获取UserId和UserName
Now I will get the UserId and UserName with below code
public static class ClaimsPrincipalExtensions
{
public static string GetSub(this ClaimsPrincipal principal)
{
return principal?.FindFirst(x => x.Type.Equals("sub"))?.Value;
}
public static string GetEmail(this ClaimsPrincipal principal)
{
return principal?.FindFirst(x => x.Type.Equals("email"))?.Value;
}
}
获取用户ID
string UserId=User.GetSub();
