在C#中,可以通過(guò)Nacos SDK來(lái)發(fā)現(xiàn)服務(wù)。以下是一個(gè)示例代碼:
using Nacos.V2;
using Nacos.V2.Naming.Dtos;
using System;
using System.Threading.Tasks;
public class DiscoveryService
{
private readonly INacosNamingService _namingService;
public DiscoveryService(string serverAddr, string namespaceId)
{
var nacosOptions = new Nacos.V2.NacosOptions()
{
ServerAddresses = new List<string> { serverAddr },
Namespace = namespaceId
};
_namingService = new NacosNamingService(nacosOptions);
}
public async Task<List<Instance>> DiscoverServices(string serviceName, string groupName, bool subscribe)
{
var instances = await _namingService.SelectInstances(serviceName, groupName, subscribe);
return instances;
}
}
// Usage
var discoveryService = new DiscoveryService("localhost:8848", "namespaceId");
var instances = await discoveryService.DiscoverServices("serviceName", "groupName", true);
foreach (var instance in instances)
{
Console.WriteLine($"Found instance: {instance.Ip}:{instance.Port}");
}
在上面的示例中,首先創(chuàng)建了一個(gè)DiscoveryService類來(lái)使用Nacos SDK來(lái)發(fā)現(xiàn)服務(wù)。在構(gòu)造函數(shù)中傳入Nacos服務(wù)器地址和命名空間ID,然后通過(guò)DiscoverServices方法來(lái)發(fā)現(xiàn)指定服務(wù)名和組名的服務(wù)實(shí)例。最后遍歷服務(wù)實(shí)例列表并輸出每個(gè)實(shí)例的IP和端口。
