关于接口使用问题

想问一下，这个接口是否如下这样使用的：

//这个new RestClient(）里面的路径是不是要加上域名然后再跟/product/product，为何我这样写了都没反应呢？我是在自己的电脑上调试的，没有收到服务器反馈

var client = new RestClient("https://www.xxx.com/product/product");

client.Timeout = -1;

var request = new RestRequest(Method.GET);

request.AddHeader("Authori-zation", "Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJwd2QiOiJkNWUxNjFlNDhiN2JjYTM0NTk1MGU3NTM0MDdlYTgxOCIsImlzcyI6IjE5Mi4xNjguMjguMjM5IiwiYXVkIjoiMTkyLjE2OC4yOC4yMzkiLCJpYXQiOjE2NjQxNTQ0ODIsIm5iZiI6MTY2NDE1NDQ4MiwiZXhwIjoxNjY2NzQ2NDgyLCJqdGkiOnsiaWQiOjEsInR5cGUiOiJhZG1pbiJ9fQ.azIMu8hK8vWUKawuqpQAgRarfz3odOqBDM_D0ne_sQE");

client.UserAgent = "Apifox/1.0.0 (https://www.apifox.cn)";

IRestResponse response = client.Execute(request);

string result = response.Content;

Response.Write(result);
