本篇内容主要讲解“asp.net微信开发中如何管理已关注用户”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“asp.net微信开发中如何管理已关注用户”吧!

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）

asp.net微信开发中如何管理已关注用户

返回说明

正确时返回JSON数据包：

asp.net微信开发中如何管理已关注用户

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：

asp.net微信开发中如何管理已关注用户

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

 /// 
 /// 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

 }
