• 后端startup配置跨域

 //配置跨域        
            services.AddCors(options =>
            {
                options.AddPolicy("AngularClient", policy =>
                 {
                     policy.WithOrigins("http://localhost:4200")
                        .AllowAnyHeader()
                        .AllowAnyMethod();
                 });
            });

 app.UseCors();

• Angular创建service
