asp.net微信开发第四篇----已关注用户管理
如果本章不明白打标签是什么意思，可以先看用户分组管理，再看本章， 本项目所用框架基于：layUI，官网：https://www.layui.com/
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）
https://api.weixin.qq.com/cgi-bin/user/get?access_token=ACCESS_TOKEN&next_openid=NEXT_OPENID
| 参数 | 是否必须 | 说明 |
|---|---|---|
| access_token | 是 | 调用接口凭证 |
| next_openid | 是 | 第一个拉取的OPENID，不填默认从头开始拉取 |
返回说明
正确时返回JSON数据包：
{"total":2,"count":2,"data":{"openid":["","OPENID1","OPENID2"]},"next_openid":"NEXT_OPENID"}
| 参数 | 说明 |
|---|---|
| total | 关注该公众账号的总用户数 |
| count | 拉取的OPENID个数，最大值为10000 |
| data | 列表数据，OPENID的列表 |
| next_openid | 拉取列表的最后一个用户的OPENID |
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"
} 本篇更新于2017年5月11日，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：
打标签：
批量打标签：
修改用户备注名：
同步官方数据：具体实现思路如下：
1.新建微信用户实体类，openID实体类，用于封装微信用户的每个属性信息，
2.从微信服务器获取到数据后（如果获取数据较多，容易出现卡死现象，我做的是ajax异步获取,加了一个加载数据的动画显示），序列化后转存到本地数据库（转存前删除本地数据库的原有用户数据），页面加载数据的时候是从本地数据库加载的，不和微信打交道，
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，用于存储openID列表
/// <summary>
/// 微信用户的OpenID实体类,此类不用来参与数据库数据存储，只是临时储存用户的openID列表
/// </summary>
public class WeChat_UserOpenIdInfo
{
/// <summary>
/// 微信用户的openID
/// </summary>
public String WeChatUserOpenId { get; set; }
}
/// <summary>
/// 微信已关注用户实体类
/// </summary>
public class WeChat_UserInfo
{
public int ID { get; set; }//编号，自增列 public string 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 country { get; set; }//国家 public string province { get; set; }//省份 public string language { get; set; }//语言 public string headimgurl { get; set; }//头像图片地址 public string subscribe_time { get; set; }//用户关注时间 public string remark { get; set; }//备注 public string groupid { get; set; }//分组ID /// <summary>
/// 用户被打上的标签ID列表
/// </summary>
public string tagid_list { get; set; } }
