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
七、项目发布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。
八、通过Nginx部署到Linux服务器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
cd /var/www/HotelWeb/ dotnet HotelWeb.dll [root@centos7 HotelWeb]# dotnet HotelWebMVC.dll info: Microsoft.Hosting.Lifetime[0] Now listening on: :5000 info: Microsoft.Hosting.Lifetime[0] Application started. Press Ctrl+C to shut down. info: Microsoft.Hosting.Lifetime[0] Hosting environment: Production info: Microsoft.Hosting.Lifetime[0] Content root path: /var/www/HotelWeb
5.安装Nginx并配置
yum install nginx vim /etc/nginx/nginx.conf --------------- # 删除nginx默认的server，添加下面两个 server { listen 80 default_server; return 444; } server { listen 80; server_name *.hotel.com; location / { proxy_pass :5000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection keep-alive; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } } ----------------
6.启动nginx
systemctl start nginx nginx -t # 配置确认没有问题后，重新载入配置 nginx -s reload
7.浏览器测试
修改win7的host
192.168.30.110
8.最后的问题
因为libgdiplus这个库没有安装，所以进入验证码的页面会有报错。
fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1]
An unhandled exception has occurred while executing the request.
System.TypeInitializationException: The type initializer for 'Gdip' threw an exception.
---> System.DllNotFoundException: Unable to load shared library 'libgdiplus' or one of its dependencies.
9.修改dotnet监听端口
在Program.cs 文件中修改
public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureWebHostDefaults(webBuilder => { webBuilder.ConfigureKestrel(serverOptions => { serverOptions.Listen(IPAddress.Any, 5000); }) .UseStartup<Startup>(); }); }
修改后
[root@centos7 HotelWeb]# dotnet HotelWebMVC.dll info: Microsoft.Hosting.Lifetime[0] Now listening on: :5000 info: Microsoft.Hosting.Lifetime[0] Application started. Press Ctrl+C to shut down. info: Microsoft.Hosting.Lifetime[0] Hosting environment: Production info: Microsoft.Hosting.Lifetime[0] Content root path: /var/www/HotelWeb [root@centos7 ~]# ss -tna State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:5000 *:* LISTEN 0 50 *:3306 *:* LISTEN 0 128 *:111 *:* LISTEN 0 128 *:80 *:* LISTEN 0 128 *:22 *:* LISTEN 0 100 127.0.0.1:25 *:* ESTAB 0 0 192.168.30.110:22 192.168.30.88:1581 ESTAB 0 52 192.168.30.110:22 192.168.30.88:1516 LISTEN 0 128 :::111 :::* LISTEN 0 128 :::22 :::* LISTEN 0 100 ::1:25 :::*
