一次在呼叫百度外賣的介面中需要對JSON取MD5,但是前提是JSON必須先排序

  1.需要用到的庫 JSON.NET

以下是原始碼

    /// <summary>
    /// JSON物件名稱排序  
    /// </summary>
    public class JsonSort
    {
       /// <summary>
       /// JSON格式化重新排序
       /// </summary>
        /// <param name="jobj">原始JSON JToken.Parse(string json);</param>
       /// <param name="obj">初始值Null</param>
       /// <returns></returns>
