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
```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
#redis.yaml 文件

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。
