本篇內容主要講解“asp.net微信開發中如何管理已關注用戶”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“asp.net微信開發中如何管理已關注用戶”吧!
公眾號可通過本接口來獲取帳號的關注者列表，關注者列表由一串OpenID（加密后的微信號，每個用戶對每個公眾號的OpenID是唯一的）組成。一次拉取調用最多拉取10000個關注者的OpenID，可以通過多次拉取的方式來滿足需求。
接口調用請求說明
http請求方式: GET（請使用https協議）
返回說明
正確時返回JSON數據包：
錯誤時返回JSON數據包（示例為無效AppID錯誤）：
{"errcode":40013,"errmsg":"invalid appid"}
附：關注者數量超過10000時
當公眾號關注者數量超過10000時，可通過填寫next_openid的值，從而多次拉取列表的方式來滿足需求。
具體而言，就是在調用接口時，將上一次調用得到的返回中的next_openid值，作為下一次調用中的next_openid值。
示例如下：
公眾賬號A擁有23000個關注的人，想通過拉取關注接口獲取所有關注的人，那么分別請求url如下：
https://api.weixin.qq.com/cgi-bin/user/get?access_token=ACCESS_TOKEN
返回結果:
{
"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
返回結果:
{
"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
返回結果（關注者列表已返回完時，返回next_openid為空）:
{
"total":23000,
"count":3000,
"data":{"
"openid":[
"OPENID20001",
"OPENID20002",
...,
"OPENID23000"
]
},
"next_openid":"OPENID23000"
}微信官方網站后臺的接口權限表里（以服務號為例）每天調用的獲取用戶列表能獲取500次，獲取用戶基本信息可以獲取500000次，所以說接下來，我在獲取用戶列表的時候，會用到緩存，別看500次不少了，
可是真正的用起來快得不得了，先上效果圖如下：
先來看看用戶列表，官網說獲取用戶的列表返回的是一組組openID，針對這個特性，我是這么做的，
創建一個用于存儲openId的類
public class WxOpenIdInfo
{
public string WxopenId { get; set; }//用戶存放微信用戶的openId
}然后再創建用戶信息的基本類
/// <summary>
/// 微信用戶基本信息類
/// </summary>
public class WxUserInfo
{
public int subscribe { get; set; }//關注狀態
public string openid { get; set; }//OpenID
public string nickname { get; set; }//昵稱
public string sex { get; set; }//性別
public string city { get; set; }//城市
public string province { get; set; }//省份
public string headimgurl { get; set; }//頭像圖片地址
public string subscribe_time { get; set; }//關注時間
public string remark { get; set; }//備注
public string groupid { get; set; }//分組ID
}用戶列表前臺代碼
