asp.net WeChat development

This article mainly introduces the related content of the followed user management in asp.net WeChat development. Friends in need can refer to the

public account through this Interface to obtain the account's follower list. The follower list consists of a string of OpenIDs (encrypted WeChat IDs, each user's OpenID for each official account is unique). A single pull call can pull up to 10,000 OpenIDs of followers, and you can pull multiple times to meet your needs.

Interface call request description

Detailed explanation of following user management steps in asp.net WeChat development

Return JSON data packet when incorrect (example is invalid AppID error):

{" errcode":40013,"errmsg":"invalid appid"}
Attachment: When the number of followers exceeds 10,000

When the number of followers of the official account exceeds 10,000, you can fill in next## The value of #_openid can be used to pull the list multiple times to meet the needs.

Specifically, when calling the interface, the next_openid value returned from the previous call is used as the next_openid value in the next call.

The example is as follows:

Public account A has 23,000 following people. If you want to get all the following people through the pull attention interface, then the respective request URLs are as follows:

https:// api.weixin.qq.com/cgi-bin/user/get?access_token=ACCESS_TOKEN

Return result:

{
 "total":23000,
 "count":10000,
 "data":{"
 openid":[
 "OPENID1",
 "OPENID2",
 ...,
 "OPENID10000"
 ]
 },
 "next_openid":"OPENID10000"
}

Copy after login

https:/ /api.weixin.qq.com/cgi-bin/user/get?access_token=ACCESS_TOKEN&next_openid=NEXT_OPENID1

Return result:

{
 "total":23000,
 "count":10000,
 "data":{
 "openid":[
 "OPENID10001",
 "OPENID10002",
 ...,

 },
 "next_openid":"OPENID20000"
}

Copy after login

##https://api.weixin.qq.com/cgi-bin/user/get?access_token=ACCESS_TOKEN&next_openid=NEXT_OPENID2
Return results (the follower list has been returned , return next_openid is empty):

{
 "total":23000,
 "count":3000,
 "data":{"
 "openid":[
  "OPENID20001",
  "OPENID20002",

is called every day in the interface permission table of the WeChat official website background (taking service account as an example) to obtain users The list

can be obtained 500 times, and the user's basic information can be obtained 500,000 times. So next, when I obtain the user list, I will use

caching. Even though 500 times is a lot, But it is really fast to use. The rendering is as follows:

Let’s take a look at the user list first. The official website says that getting the user list returns: A group of openIDs. For this feature, I did this, Detailed explanation of following user management steps in asp.net WeChat development Create a class for storing openId

public class WxOpenIdInfo
 {
 public string WxopenId { get; set; }//用户存放微信用户的openId
 }

Copy after login

And then create a basic class of user information

 /// <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

 }

Copy after login
