参考Docker创建运行多个mysql容器,地址 http://www.cnblogs.com/heyangyi/p/9288402.html
添加user数据库,添加tbusers表
参考Docker 为 ASP.NET Core WebApi 应用程序生成 Docker 映像,创建容器并运行,地址 http://www.cnblogs.com/heyangyi/p/9323407.html
<2.1> 修改 appsettings.json 文件,添加 dbconn 数据库链接配置
<2.2> 新增Config类,用来存储配置
public class Config { public static string dbconn; }
<2.3> 修改Program 类,读取配置
public class Program { private static IConfigurationRoot Configuration { get; set; } public static void Main(string[] args) { var builder = new ConfigurationBuilder() .SetBasePath(Directory.GetCurrentDirectory()) .AddJsonFile("appsettings.json"); Configuration = builder.Build(); Config.dbconn = Configuration.GetValue<string>("dbconn"); BuildWebHost(args).Run(); } public static IWebHost BuildWebHost(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .Build(); }
<2.4> 新增DataContext类
安装引用:MySql.Data.EntityFrameworkCore
public class DataContext : DbContext { public DbSet<tbuser> tbusers { get; set; } protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) => optionsBuilder.UseMySQL(Config.dbconn); }
public class tbuser { [DatabaseGenerated(DatabaseGeneratedOption.None)] public int id { get; set; } public string nickName { get; set; } public string email { get; set; } }
<2.5> 新增tbuserDataHandle类
public class tbuserDataHandle : DataContext { public static int adduser(tbuser user) { try { using (var context = new DataContext()) { context.Database.EnsureCreated(); context.Add(user); context.SaveChanges(); } return 200; } catch (Exception ex) { return 300; } } public static List<tbuser> Get() { try { using (var context = new DataContext()) { var users = context.tbusers; List<tbuser> items = new List<tbuser>(); foreach (var item in users) { items.Add(item); } return items; } } catch (Exception ex) { return null; } } public static tbuser Get(int id) { try { using (var context = new DataContext()) { var u = context.tbusers.Find(id); return u; } } catch (Exception ex) { return null; } } public static int Delete(int id) { try { using (var context = new DataContext()) { var u = context.tbusers.Remove(new tbuser() { id = id }); context.SaveChanges(); return 200; } } catch (Exception ex) { return 300; } } public static int Put(int id, tbuser user) { try { using (var context = new DataContext()) { var u = context.tbusers.Update(user); context.SaveChanges(); return 200; } } catch (Exception ex) { return 300; } } }
<2.6> 新增userController Api
[Produces("application/json")] [Route("api/user")] public class userController : Controller { // POST api/user [HttpPost] public int Post(tbuser user) { return tbuserDataHandle.adduser(user); } // GET api/user [HttpGet] public List<tbuser> Get() { return tbuserDataHandle.Get(); } // GET api/user/5 [HttpGet("{id}")] public tbuser Get(int id) { return tbuserDataHandle.Get(id); } // DELETE api/user/5 [HttpDelete("{id}")] public int Delete(int id) { return tbuserDataHandle.Delete(id); } // PUT api/user/5 [HttpPut("{id}")] public int Put(int id, tbuser user) { return tbuserDataHandle.Put(id, user); } }
修改 docker-compose.yml ,docker-compose.override.yml 的 version 为:
version: ‘2.0‘
配置 appsettings.json 的 dbconn 为:
"dbconn": "server=192.168.99.100;user id=root;password=123456;persistsecurityinfo=True;port=3307;database=user;SslMode=none"
进入到 E:\web\ilinkcore (这个目录为解决方案的根目录)
docker-compose up
执行成功后创建一个 ilinkcore 的镜像,并且运行了一个 ilinkcore_ilinkcore_1的容器,将本机的32783端口映射到容器的80端口
添加反向代理,修改nginx 配置
server{ listen 84; server_name localhost; location / { proxy_pass http://192.168.99.100:32783; index index.html index.htm; } }
重新运行nginx,使用Postman进行api接口测试
<4.1> 测试接口进行添加user数据
Headers 中添加项:
Content-Type:application/json
<4.2>查看所有用户数据
<4.3> 检索某个用户数据
<4.4> 更新某个用户数据
Headers 中添加项:
Content-Type:application/json
<4.5> 删除单个用户
asp.net core webapi 使用ef 对mysql进行增删改查,并生成Docker镜像构建容器运行
