快乐宝贝逗你玩
公众号可通过本接口来获取帐号的关注者列表，关注者列表由一串openid（加密后的微信号，每个用户对每个公众号的openid是唯一的）组成。一次拉取调用最多拉取10000个关注者的openid，可以通过多次拉取的方式来满足需求。
接口调用请求说明
http请求方式: get（请使用https协议）
返回说明
正确时返回json数据包：
错误时返回json数据包（示例为无效appid错误）：
{"errcode":40013,"errmsg":"invalid appid"}
附：关注者数量超过10000时
当公众号关注者数量超过10000时，可通过填写next_openid的值，从而多次拉取列表的方式来满足需求。
具体而言，就是在调用接口时，将上一次调用得到的返回中的next_openid值，作为下一次调用中的next_openid值。
示例如下：
公众账号a拥有23000个关注的人，想通过拉取关注接口获取所有关注的人，那么分别请求url如下：
https://api.weixin.qq.com/cgi-bin/user/get?access_token=access_token
返回结果:
{
"total":23000,
"count":10000,
"data":{"
openid":[
"openid1",
"openid2",
...,
"openid10000"
]
},
"next_openid":"openid10000"
}
https://api.weixin.qq.com/cgi-bin/user/get?access_token=access_token&next_openid=next_openid1
返回结果:
{
"total":23000,
"count":10000,
"data":{
"openid":[
"openid10001",
"openid10002",
...,
"openid20000"
]
},
"next_openid":"openid20000"
}
https://api.weixin.qq.com/cgi-bin/user/get?access_token=access_token&next_openid=next_openid2
返回结果（关注者列表已返回完时，返回next_openid为空）:
{
"total":23000,
"count":3000,
"data":{"
"openid":[
"openid20001",
"openid20002",
...,
"openid23000"
]
},
"next_openid":"openid23000"
}
微信官方网站后台的接口权限表里（以服务号为例）每天调用的获取用户列表能获取500次，获取用户基本信息可以获取500000次，所以说接下来，我在获取用户列表的时候，会用到缓存，别看500次不少了，
可是真正的用起来快得不得了，先上效果图如下：
先来看看用户列表，尊龙凯时官网说获取用户的列表返回的是一组组openid，针对这个特性，我是这么做的，
创建一个用于存储openid的类
public class wxopenidinfo
{
public string wxopenid { get; set; }//用户存放微信用户的openid
}
然后再创建用户信息的基本类
////// 微信用户基本信息类 /// public class wxuserinfo { public int subscribe { get; set; }//关注状态 public string openid { get; set; }//openid public string nickname { get; set; }//昵称 public string sex { get; set; }//性别 public string city { get; set; }//城市 public string province { get; set; }//省份 public string headimgurl { get; set; }//头像图片地址 public string subscribe_time { get; set; }//关注时间 public string remark { get; set; }//备注 public string groupid { get; set; }//分组id }
用户列表前台代码
<%@ page language="c#" autoeventwireup="true" codebehind="weixinuserlist.aspx.cs" inherits="dqwebsite.administrator.weixinuserlist" %>
获取用户列表绑定用户信息的后台代码，已包括，修改备注名，将用户移动到分组，新建分组代码
分组统计，用于显示每个分组的已存在人数，无其他作用
