Question

我使用该代码来获取订单的状态代码，订单的价值。但它有一些错误，它已被禁止。我该如何解决这个问题？

private HttpResponseMessage TheOrderContent;
private HttpClient TheGetOrderHttpClient;
private HttpRequestMessage TheGetOrderHttpRequest;

TheGetOrderHttpClient = new HttpClient();
TheGetOrderHttpRequest = new HttpRequestMessage(new HttpMethod("GET"), "https://selly.gg/api/v2/orders/d453efd6-db5b-4b59-83ca-3400862a55e3");
TheGetOrderHttpRequest.Headers.TryAddWithoutValidation("Authorization", "Basic " + {MyAPIKeyThenICanNotShow});
TheOrderContent = await TheGetOrderHttpClient.SendAsync(TheGetOrderHttpRequest);
Console.WriteLine(TheOrderContent.ToString());

错误代码：403 - 禁止！帮助！
