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"htmlcode">
{ "total":23000, "count":10000, "data":{" openid":[ "OPENID1", "OPENID2", ..., "OPENID10000" ] }, "next_openid":"OPENID10000" }
https://api.weixin.qq.com/cgi-bin/user/get"htmlcode">
{ "total":23000, "count":10000, "data":{ "openid":[ "OPENID10001", "OPENID10002", ..., "OPENID20000" ] }, "next_openid":"OPENID20000" }
https://api.weixin.qq.com/cgi-bin/user/get"htmlcode">
{ "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 }

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
