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; }
    }
}

部署到k8s

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.
