如下是实际代码中调用上述类方法：
#region 到金蝶ERP中查询规格型号以作信息比对
Class.HttpClient httpClient = new Class.HttpClient();

var iResult = JObject.Parse(httpClient.AsyncRequest())["LoginResultType"].Value<int>();
if (iResult == 1)
{
//todo:验证成功，处理业务

//Json字串

// 发送请求并等待响应

// 获取嵌套的 result 下的 result 下的 specification 值

// 将JToken转换为字符串（如果需要）
string specificationValue = specificationToken.ToString();
if (specificationToken != null)
{
string specification = specificationToken.ToString();
// 处理 specification 值
