         隨着技術的不斷拓展更新，咱們所使用的技術也在不斷地升級優化，項目的框架也在不斷地升級，本次講解 .net core 2.1  升級到3.1所須要注意的事項；web

   當項目框架升級後，全部的Nuget引用也會對應變化，這些根據本身的框架所使用的技術對應作升級便可，這裏不作過多贅述；redis

其次就是要修改 Program.cs 文件，這裏把修改前的和修改後的統一貼出代碼作調整，代碼以下：json

2.1版本的文件代碼：api

using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using System;

namespace S2_Xxxx_XxxNetApi
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
            Console.WriteLine("接口啓動成功");
           // QuartzHelper.ExecuteInterval<Test>(200);
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
            //.UseUrls("http://*:5000")//發佈時須要註釋
            .UseStartup<Startup>();
    }
}

3.1版本的文件代碼跨域

using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Hosting;
using System;

namespace S2_Cggc_PmsNetApi
{
    /// <summary>
    /// 啓動
    /// </summary>
    public class Program
    {
        /// <summary>
        /// 啓動
        /// </summary>
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).Build().Run();
            Console.WriteLine("接口啓動成功");
        }

        /// <summary>
        /// 啓動
        /// </summary>
        public static IHostBuilder CreateHostBuilder(string[] args) =>
                Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }
}

而後就是Startup文件，代碼以下：瀏覽器

2.1版本文件代碼：cookie

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Infrastructure;

using System.Linq;

{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            //調度任務註冊
            services.AddSingleton<ISchedulerFactory, StdSchedulerFactory>();//註冊ISchedulerFactory的實例。

            string conn = Configuration.GetSection("AppSettings:ConnectString").Value;
            MySqlHelper.Conn = conn;

            string orclconn = Configuration.GetSection("AppSettings:OrclConnectString").Value;
            OracleHelper.connectionString = orclconn;

            string redisconn = Configuration.GetSection("AppSettings:RedisConnectString").Value;
            RedisHelper.SetCon(redisconn);
            RedisHelper.BuildCache();

            services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));

            //跨域支持
            services.AddCors(options =>
            {
                options.AddPolicy("CorsPolicy",
                    corsBuild => corsBuild.AllowAnyOrigin()
                    .AllowAnyMethod()
                    .AllowAnyHeader()
                    .AllowCredentials());
            });

            services.Configure<CookiePolicyOptions>(options =>
            {
                options.CheckConsentNeeded = context => false;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });
            services.AddDistributedMemoryCache();//啓用session以前必須先添加內存
                                                 //services.AddSession();
            services.AddSession(options =>
            {
                options.Cookie.Name = ".AdventureWorks.Session";
                options.IdleTimeout = System.TimeSpan.FromSeconds(1200);//設置session的過時時間
                options.Cookie.HttpOnly = true;//設置在瀏覽器不能經過js得到該cookie的值
            });

            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
            services.AddSingleton<IActionContextAccessor, ActionContextAccessor>();

            services.AddSwaggerGen(options =>
            {
                options.SwaggerDoc("v1", new Swashbuckle.AspNetCore.Swagger.Info
                {
                    Version = "v1",
                    Title = "接口文檔"
                });
                options.ResolveConflictingActions(apiDescriptions => apiDescriptions.First());
            });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                //app.usehets();
            }
            app.UseSession();
            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "WebAPI文檔");
            });


            //跨域支持
            app.UseCors("CorsPolicy");
            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });


        }
    }
}

作了對應調整後，編譯後檢查是否還有錯誤提示，便可升級成功，可能有些控制器裏面的屬性寫法也會有些變化，這個尚未具體深刻研究，歡迎小夥伴們作補充，我將虛心接受你們的意見，感謝~app
