WebAPI2使用表格angular2错误未找到

Question

I wont to consume Web Api2 async in Angular2 project, but i have some errors, when i try a request to the method.

My method is:

 private baseUrl2 ='http://localhost:50348/api/Users/GetUsers'
    getuser(): Observable<IUser[]>
    {

        console.log(this.baseUrl2);
        return this.http.get(this.baseUrl2)
            .map(res => res.json())
            .do(data => console.log('getuser: ' + JSON.stringify(data)))
            .catch(this.handleError);
    }

My [HttpGet] method at WebApi is :

[HttpGet]
    public IEnumerable<User> GetUsers()
    {
        return db.Users.ToList();
    }

I have configure Microsoft.AspNetCore.Cors also and at Startup.cs i put AllowSpecificOrigin policy:

public void ConfigureServices(IServiceCollection services)
        {
            services.AddCors(options =>
            {
                options.AddPolicy("AllowSpecificOrigin",
                    builder => builder.WithOrigins("http://localhost:50348/"));
            });
        }

        public void Configure(IApplicationBuilder app)
        {

            // Shows UseCors with named policy.
            app.UseCors("AllowSpecificOrigin");

        }

But when i run my angular project a call method form angular project i have an error as:

Object { _body: Object, status: 404, ok: false, statusText: "Not Found", headers: Object, type: null, url: " http://localhost:50348/api/Users/Ge …" }

When i try to call web api method from browser , not form angular project ,it works

[{"Country":"test","Id":1,"Name":"test","OtherInfo":"test","Surname":"test"}]

Whats wrong? Could you help me?

You can try

[HttpGet]
    public IEnumerable<dynamic> Get()
    {
        return _context.Employee.ToList();
    }
