asp.net微信开发(已关注用户管理) 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:
http://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"
}
http://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"
}
http://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 ///
/// 微信用户基本信息类
///

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 } 用户列表前台代码<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WeiXinUserList.aspx.cs" Inherits="DQWebSite.Administrator.WeiXinUserList" %>
