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 调用接口凭证
next_openid 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; }


    }

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,打标签(将用户移动到标签组),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

上代码:

 PagedDataSource pds = new PagedDataSource();
        protected void Page_Load(object sender, EventArgs e)
        {
           if(!Page.IsPostBack)

至于Newtonsoft.json.dll文件,可在百度中搜索下载,如有需要,也可留下你的邮箱,我发邮件给你,至此用户管理模块告一段落!如有不对之处,欢迎指导!
