.NET Core Web API / Angular 应用程序中的 Windows 身份验证

我正在使用 Visual Studio 2019 Community 构建一个 Intranet 应用程序，用于创建 .NET Core Web Api（使用 .NET Core 2.2），并使用 Visual Studio Code 来创建 Angular 前端（@angular/cdk 7.1.0、@angular/cli 7.0 .6，@角度/材料7.1.0）。 由于它是一个 Intranet 应用程序，我想实现 Windows 身份验证，以便用户不必再次输入其凭据。 我声明我已经尝试过这个和其他论坛但没有成功，我对这些技术不是很熟悉，所以我需要帮助来解决我遇到的一些问题，我可能不明白 CORS 是如何工作的。

我也尝试从邮递员调用我的 Web API（默认设置=“授权：从父级继承身份验证”...），但结果相同。 我已经从 NuGet 安装了 Microsoft.AspNetCore.Cors 并实现了以下代码。

在 Web API 方面，我有这段代码。

启动设置.json

{
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": true,
    "anonymousAuthentication": false,
    "iisExpress": {
      "applicationUrl": "http://localhost:62148",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "api/values",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "WebApiWinAuth": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "api/values",
      "applicationUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

启动.cs

public void ConfigureServices(IServiceCollection services)
{
                services.AddCors(c =>
    {
        c.AddPolicy("AllowOrigin",
            options => options
                    .AllowAnyOrigin()
                    //.WithOrigins("http://localhost:4200")
                    .AllowAnyMethod()
                    .AllowAnyHeader()
                );
    });

    services.AddMvc()
        .SetCompatibilityVersion(CompatibilityVersion.Version_2_2)
        .AddJsonOptions(options =>
        {
            var resolver = options.SerializerSettings.ContractResolver;
            if (resolver != null)
                (resolver as DefaultContractResolver).NamingStrategy = null;
        });
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    app.UseCors(options => options
        .AllowAnyOrigin()
        //.WithOrigins("http://localhost:4200")
        .AllowAnyMethod()
        .AllowAnyHeader()
   );

    app.UseMvc();
}

ValuesController.cs

[Route("api/[controller]")]
[ApiController]
[Authorize]
[EnableCors("AllowOrigin")]
public class ValuesController : ControllerBase
{
    // GET api/values
    [EnableCors("AllowOrigin")]
    [HttpGet]
    [Authorize]
    public ActionResult<string> Get()
    {
        var userId = HttpContext.User.Identity.Name;
        return userId;
    }
}

在有角度的一侧我有这个代码。

身份.服务.ts

import { Injectable } from '@angular/core';
import { HttpClient, HttpParams, HttpHeaders } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class IdentityService {

  constructor(private http:HttpClient) { }

  getCurrentUser() {

    const httpOptions = {
      headers: new HttpHeaders({
        'Content-Type': 'application/json'
      }),
      withCredentials: true
     };
    return this.http.get('http://localhost:62148/api/values', httpOptions)
      .toPromise();
  }
}

应用程序组件.ts

export class AppComponent implements OnInit {
  title = 'Angular WinAuth';
  currentUser:string;

  constructor(private service: IdentityService) { }

  ngOnInit() {
    this.service.getCurrentUser().then(res => this.currentUser = res as string);
  }
}

我不断收到的响应是来自 Postman 和 Angular 应用程序的“HTTP 错误 401.2 - 未经授权”。

我哪里做错了？ 我应该如何实现从Angular到Web Api的调用？

如果我需要发布另一个代码，请告诉我。 提前致谢

当我设置时它起作用anonymousAuthentication:true in launchSettings.json:

"iisSettings": {
"windowsAuthentication": true, 
"anonymousAuthentication": true, 
"iisExpress": {
  "applicationUrl": "http://localhost:62148",
  "sslPort": 0
}

并且从介绍 and CORS https://learn.microsoft.com/en-us/aspnet/core/security/cors?view=aspnetcore-2.2#cors-with-named-policy-and-middleware在asp.net core中，我更改startup.cs，如下所示：

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddAuthentication(IISDefaults.AuthenticationScheme);//Add this line
        services.AddCors(c =>
        {
            c.AddPolicy("AllowOrigin",
                options => options
                        //.AllowAnyOrigin()
                        .WithOrigins("http://localhost:4200")
                        .AllowAnyMethod()
                        .AllowAnyHeader()
                        .AllowCredentials()//Add this line
                    );
        });

        services.AddMvc()
            .SetCompatibilityVersion(CompatibilityVersion.Version_2_2)
            .AddJsonOptions(options =>
            {
                var resolver = options.SerializerSettings.ContractResolver;
                if (resolver != null)
                    (resolver as DefaultContractResolver).NamingStrategy = null;
            });

    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }

        app.UseCors("AllowOrigin");

        app.UseMvc();
    }
}
