.NET微信公众号查看关注者接口 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 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 unionid { get; set; } public string remark { get; set; } public int groupid { get; set; } public int[] tagid_list { get; set; } } getUser.aspx代码: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="getUser.aspx.cs" Inherits="MyTest.WebUI.Manager.usermsg.getUser" %>
