配置服务和配置代码:

// This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {

            services.AddControllers();
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new OpenApiInfo { Title = "WallyRest", Version = "v1" });
            });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)

                app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "WallyRest v1"));
            }

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>

您看到的问题与以下代码有关:

if (env.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
    app.UseSwagger();
    app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "WallyRest v1"));
}

当您从VisualStudio运行代码时,它通常会设置 ASPNETCORE_ENVIRONMENT “发展”的环境变量:

这反过来会在应用程序启动时将代码中的环境设置为“开发”。如果未设置此值,则默认为“生产”

这最终意味着 if (env.IsDevelopment()) 将评估为 false

解决方案是简单地将您的招摇过市代码移出此块:

if (env.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
}

app.UseSwagger();
app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "WallyRest v1"));
