[ASP.net教程]asp.net微信开发第四篇


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"}

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; }//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  }

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

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!
