新建webapi项目

• 建项目时取消https支持，勾选docker支持，
  
• Program.cs中注释下面语句，这样部署后才能访问Swagger

  // Configure the HTTP request pipeline.
  //if (app.Environment.IsDevelopment())
  {
    app.UseSwagger();
    app.UseSwaggerUI();
  }
  

• 添加Dapr.Client与Dapr.AspNetCore两个nuget包
• 修改Program.cs文件，增加dapr sdk支持
  
• 修改WeatherForecastController.cs文件
  ```
  using Dapr;
  using Dapr.Client;
  using Microsoft.AspNetCore.Mvc;

namespace backend.Controllers
{
[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
private readonly DaprClient _daprClient;
public WeatherForecastController(DaprClient daprClient)
{
_daprClient = daprClient;
}

    [HttpGet(Name = "GetWeatherForecast")]
    public object Get()
    {
        return new { message = "Hello Dapr!" };
    }


    [HttpPost(nameof(SaveStateValue))]
    public async Task SaveStateValue(StateModel stateModel)
    {
        await _daprClient.SaveStateAsync("statestore", stateModel.Key, stateModel.Value);//statestore
    }
    [HttpDelete(nameof(DeleteStateValue) + "/{stateKey}")]
    public async Task DeleteStateValue(string stateKey)
    {
        await _daprClient.DeleteStateAsync("statestore", stateKey);
    }
    [HttpGet("GetStateValue/{stateKey}")]
    public async Task<string> GetStateValue(string stateKey)
    {
        return await _daprClient.GetStateAsync<string>("statestore", stateKey);
    }

    [HttpGet(nameof(GetStateValueFromState) + "/{stateKey}")]
    public async Task<string> GetStateValueFromState([FromState("statestore", "stateKey")] StateEntry<string> stateEntry)
    {
        return await Task.FromResult(stateEntry.Value);
    }
}

}

增加文件StateModel.cs

namespace backend.Controllers
{
public class StateModel
{
public string Key { get; set; }
public string Value { get; set; }
}
}

# dapr自托管部署

修改launchSettings.json文件，端口改成5002，如下图

![](https://wxy-blog.oss-cn-hangzhou.aliyuncs.com/wxy-blog/2024/202405290847807.png)

```c#
dapr init
dapr run --app-id front --app-port 5002 dotnet run

访问http://localhost:5002/swagger/index.html

操作各个方法，都符合预期就对了

部署到k8s

dapr init -k
kubectl apply -f redis.yaml
kubectl apply -f statestore.yaml
kubectl apply -f dapr-front.yaml

验证是否成功

我是nat到虚拟机
测试接口，如果都能正常设置状态，获取状态，删除状态就OK了

遇到问题

我上面部署成功的是在vmare虚拟机k8s集群上测试成功了，但我在win11本地测试时死也成功不了，搞了好几天都搞不定
pod运行不了，知道的大佬指点一下啊。
《Blazor+Dapr+K8s微服务之状态管理》 本地运行能成功。
