基于.NET Core 3.1 网站开发和部署的方法

public void ConfigureServices(IServiceCollection services) { //其他代码省略了 ... services.AddDbContext<DBUtility.HotelWebDbContext>( options => options.UseMySql( Configuration.GetConnectionString("HotelWeb"), x => x.ServerVersion("5.5.64-mariadb") ) ); services.AddTransient<INewsManager, NewsManager>(); services.AddTransient<IDishManager, DishManager>(); services.AddTransient<IDishBookManager, DishBookManager>(); services.AddTransient<ISuggestionManager, SuggestionManager>(); services.AddTransient<IRecruitmentManager, RecruitmentManager>(); services.AddTransient<ISysAdminManager, SysAdminManager>(); services.AddTransient<INewsService,NewsService>(); services.AddTransient<IDishService,DishService>(); services.AddTransient<IDishBookService,DishBookService>(); services.AddTransient<ISuggestionService,SuggestionService>(); services.AddTransient<IRecruitmentService,RecruitmentService>(); services.AddTransient<ISysAdminService,SysAdminService>(); }

4.修改代码使用依赖注入

public class HomeController : Controller { private readonly INewsManager newsManager; private readonly ISuggestionManager suggestionManager; private readonly IRecruitmentManager recruitmentManager; public HomeController( INewsManager newsManager, ISuggestionManager suggestionManager, IRecruitmentManager recruitmentManager) { this.newsManager = newsManager; this.suggestionManager = suggestionManager; this.recruitmentManager = recruitmentManager; } // ... }

5.测试

启动项目也没有什么问题

1.项目配置

dotnet core 中没有Web.conf文件了。
查看文档，都是通过Startup.cs中配置项目的。
暂时放弃配置。

2.命令行发布项目

CLI 提供了发布项目的相关命令

dotnet publish -c Release --no-self-contained -o /path/to/save/project/

3.另一种方式使用vs发布

很简单，下一步下一步做就好了。

1.在Centos7 上安装运行时

Register Microsoft key and feed

sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm

Install the ASP.NET Core runtime

sudo yum install dotnet-sdk-3.1

2.安装libgdiplus

因为项目中使用验证码，需要用到这个命名空间：System.Drawing.Common
速度太慢，放弃。

3.将项目目录上传到linux

使用xshell 的ftp 轻松完成。

4.测试项目是否运行
