Technology stack: C#, .Net Core, Consul
Description: It is a service locator of microservice architecture, which can resolve service name to a real server address.
Just like RestTemplate in the Spring Cloud, RestTemplateCore can resolve the service name in Consul to the physical address, for example: http://ProductService/api/Product/ --> http://192.168.1.21:5000/api/Product/
Example:
using System;
using System.Net.Http;
namespace RestTemplateCore.Tests
{
class Program
{
static void Main(string[] args)
{
using (HttpClient httpClient = new HttpClient())
{
RestTemplate rest = new RestTemplate(httpClient, "http://127.0.0.1:8500");//"http://127.0.0.1:8500" is the the address of Consul
Console.WriteLine("---querying---------");
var headers = new HttpRequestMessage().Headers;
headers.Add("aa", "666");
var ret1 = rest.GetForEntityAsync<Product[]>("http://ProductService/api/Product/", headers).Result;
Console.WriteLine(ret1.StatusCode);
if (ret1.StatusCode == System.Net.HttpStatusCode.OK)
{
foreach (var p in ret1.Body)
{
Console.WriteLine($"id={p.Id},name={p.Name}");
}
}
Console.WriteLine("---add new---------");
Product newP = new Product();
newP.Id = 888;
newP.Name = "xinzeng";
newP.Price = 88.8;
var ret = rest.PostAsync("http://ProductService/api/Product/", newP).Result;
Console.WriteLine(ret.StatusCode);
}
Console.ReadKey();
}
}
}
