asp.net微信开发已关注用户管理步骤详解
这篇文章主要介绍了asp.net微信开发中有关已关注用户管理的相关内容，需要的朋友可以参考下
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，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 /// <summary> /// 微信用户基本信息类 /// </summary> public class WxUserInfo { public int subscribe { 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" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"><meta http-equiv="Content-Type" content="text/html;
