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; }//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

  }
