C# Restsharp SimpleAuthenticator

我正在使用restsharp创建RESTAPI客户端。这是我的代码：

        var client = new RestClient("https://url.com");
        client.Authenticator = new SimpleAuthenticator("client_id", "testapi", "client_secret", "password");

        var request = new RestRequest("webapi/rest/auctions", Method.GET);
        request.AddParameter("limit", "10"); 
        request.AddParameter("order", "auction_id"); 
        request.AddParameter("page", "1"); 
        request.AddParameter("offset", "0");

        IRestResponse response = client.Execute(request);
        Console.WriteLine("request: " + response.Content);

响应总是：

{“error”：“unauthorized_client”}

从这个rest api的文档中，您是否在Fiddler中查看了该请求，以验证其上是否有授权头？您的基本URI是否正确？
