.NET Core API 使用Swagger

1.项目右键-管理NuGet程序包添加Swashbuckle.AspNetCore

2.修改Startup.cs中的ConfigureServices方法

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc().AddJsonOptions(options =>
            {
                options.SerializerSettings.ContractResolver = new         DefaultContractResolver();
            });

            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new Swashbuckle.AspNetCore.Swagger.Info { Title = "My API", Version = "v1" });
            });
        }    

3.修改Startup.cs中的Configure方法

        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseMvc();

            app.UseSwagger(c =>
            {
                c.PreSerializeFilters.Add((swagger, httpReq) => swagger.Host = httpReq.Host.Value);
            });

            app.UseSwaggerUI(c =>
            {
                c.RoutePrefix = ""; // serve the UI at root
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "V1 Docs");
            });
        }

4.删除Properties/launchSettings.json中的 "launchUrl": "api/values",

5.此时可以使用Swagger
