本文实例为大家分享了java获取不同路径的方法，供大家参考，具体内容如下

实体类:

public class userlist { public string total { get; set; } public string count { get; set; } public userlistopenid data { get; set; } public string next_openid { get; set; } } public class userlistopenid { public List<string> openid { get; set; } public class userdetail { public int subscribe { get; set; } public string openid { get; set; } public string nickname { get; set; } public int sex { get; set; } public string language { get; set; } public string city { get; set; } public string province { get; set; } public string country { get; set; } public string headimgurl { get; set; } public int subscribe_time { get; set; } public string union id { get; set; } public string remark { get; set; } public int groupid { get; set; } public int[] tagid_list { get; set; } }

getUser.aspx代码:

mainArg.cs获取accessToken帮助类：

JSon序列化，反序列化

public class JsonEntityExchange<T> where T:new() { /// <summary> /// json转实体LIST /// </summary> /// <param name="JsonStr"></param> /// <returns></returns> public static List<T> Json2Entitys(string JsonStr) { JavaScriptSerializer Serializer = new JavaScriptSerializer(); List<T> objs = Serializer.Deserialize<List<T>>(JsonStr); return objs; } /// <summary> /// json转实体 /// </summary> /// <param name="json"></param> /// <returns></returns> public static T Json2Entity(string json) { T obj = Activator.CreateInstance<T>(); using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json))) { DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType()); return (T)serializer.ReadObject(ms); } } /// <summary> /// 实体转json /// </summary> /// <param name="lists">实体list</param> /// <returns></returns> public static string Entity2Json(List<T> lists) { return new JavaScriptSerializer().Serialize(lists); } }
