c# - CheckID 没有关联的 TTL

Question

我正在尝试利用 Consul .NET API 通过 TTL 注册和启动运行状况检查。首先，我使用以下代码注册我的服务:

var address = node.Address;
var id = ServiceId(address);
var registration = new AgentServiceRegistration
{
    ID = id,
    Name = node.ClusterName,
    Address = node.Address.Host,
    Port = node.Address.Port.Value,
    Check = new AgentServiceCheck
    {
        TTL = settings.AliveInterval, // 10sec
        DeregisterCriticalServiceAfter = settings.AliveTimeout, // 60sec
    }
};    
// first, try to deregister service, if it has been registered previously
await consul.Agent.ServiceDeregister(registration.ID);
await consul.Agent.ServiceRegister(registration);

紧接着，我尝试通过以下方式触发 TTL:

await consul.Agent.PassTTL("service:" + ServiceId(addr), string.Empty);

然而，我最终得到的是在 PassTTL 期间抛出的异常:Consul.ConsulRequestException: Unexpected response, status code InternalServerError: CheckID "service:{service-id}"does not have associated TTL

以及来自consul agent本身的相关日志:

[ERR] http: Request PUT /v1/agent/check/pass/service:{service-id}, error: CheckID "service:{service-id}" does not have associated TTL from=127.0.0.1:25419

我想知道我在这里做错了什么。

我正在使用 consul agent -dev(版本:1.0.1)和 Nuget 包 Consul(版本:0.7.2.3)。

Answer 1

事实证明 AgentServiceRegistration.Check 属性非常无用。我用 CheckRegister 方法达到了预期的结果。

这是代码

var registration = new AgentServiceRegistration
{
    ID = "serviceId",
    Name = node.ClusterName,
    Address = node.Address.Host,
    Port = node.Address.Port.Value
};    
// first, try to deregister service, if it has been registered previously
await consul.Agent.ServiceDeregister(registration.ID);
await consul.Agent.ServiceRegister(registration);
await consul.Agent.CheckRegister(new AgentCheckRegistration()
{
    ID = "checkId",
    Name = "Check Name",
    Status = HealthStatus.Passing,
    TTL = settings.AliveInterval,
    ServiceID = "serviceId",
    DeregisterCriticalServiceAfter = settings.AliveTimeout, // 60sec
})

现在你可以通过

await consul.Agent.PassTTL("checkId", string.Empty);
