1.构建运行mysql容器，添加数据库user
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
2.创建asp.net core webapi 应用程序
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);
}
}
3.生成项目，构建docker镜像并创作容器运行
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
4.测试访问接口
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
