WeChat public account tag management function developed by C# WeChat-WeChat Development-php.cn

WeChat public account, following the idea of enterprise account, adds the function of tag management. Tag management can be set for fans who follow it to achieve a more convenient group management function. Developers can use the relevant interfaces of user tag management to create, query, modify, delete and other operations on public account tags, and can also tag and cancel tags for users. This essay mainly introduces how to use C# to encapsulate the newer feature of public accounts and realize the management function of tags.

1. Introduction to tag function

1) The tag function replaces the grouping function and supports multi-dimensional definition of user attributes

Operators can log in In the backend of the public platform, click "User Management" on the left menu to manage the users you have followed. Click the "Tag" icon on the right side of one of the users to pop up a check box to quickly add a tag to the user, and the Add Tag check box has been Supports creating new tags directly.

In addition, the label function interface has also been updated. Developers can call the interface to implement label and user operations. At the same time, the advanced group messaging interface and personalized menu interface already support operations based on tags.

2) Optimize user cards, support viewing of user avatars and interactive data in multiple scenarios, and enhance operators’ familiarity with users and management efficiency

##This issue adds interactive data such as the number of messages, comments and appreciations, and displays the user's attention time and supports viewing of the user's avatar image, which is helpful to shorten the distance between the operator and the user. In addition, it supports "appreciation function" and "message management" scenarios to directly manage users to improve management efficiency.

2. Tag interface encapsulation

The tag interface is divided into two parts: tag management and user management. A public account can create up to 100 tags. The label function currently supports public accounts to label up to three labels for users.

Tag management includes:

1) Create tags 2) Get the tags created by the official account 3) Edit tags 4) Delete tags 5) Get fans under the tags User management of list

tags includes:

1) Tag users in batches 2) Untag users in batches 3) Get the list of tags on users

The following is a relevant introduction to several interface encapsulations.

First, in the conventional way, we define the relevant interfaces and implementation relationships, as shown in the figure below.

According to the relevant interface description, we can implement the definition of the label interface. The C# code is as follows.

/// <summary>
/// 微信标签管理的API接口
/// 开发者可以使用用户标签管理的相关接口，实现对公众号的标签进行创建、查询、修改、删除等操作，也可以对用户进行打标签、取消标签等操作。
/// </summary>
public interface ITagApi
{ 
/// <summary>
/// 创建标签
/// 一个公众号，最多可以创建100个标签。
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="name">标签名（30个字符以内）</param>
/// <returns></returns>
TagJson CreateTag(string accessToken, string name);
/// <summary>
/// 获取公众号已创建的标签
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <returns></returns>
List<TagCountJson> GetTagList(string accessToken);
/// <summary>
/// 编辑标签
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="id">标签ID</param>
/// <param name="name">标签名称</param>
/// <returns></returns>
CommonResult UpdateTag(string accessToken, int id, string name);
/// <summary>
/// 删除标签
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="id">标签ID</param>
/// <returns></returns>
CommonResult DeleteTag(string accessToken, int id);
/// <summary>
/// 获取标签下粉丝列表
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="id">标签ID</param>
/// <param name="name">标签名称</param>
/// <returns></returns>
GetTagResult GetTag(string accessToken, int id, string next_openid = null);
/// <summary>
/// 批量为用户打标签
/// 标签功能目前支持公众号为用户打上最多三个标签。
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="tagid">标签ID</param>
/// <param name="openid_list">粉丝列表</param>
/// <returns></returns>
CommonResult BatchTagging(string accessToken, int tagid, List<string> openid_list);
/// <summary>
/// 批量为用户取消标签
/// 标签功能目前支持公众号为用户打上最多三个标签。
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="tagid">标签ID</param>
/// <param name="openid_list">粉丝列表</param>
/// <returns></returns>
CommonResult BatchUntagging(string accessToken, int tagid, List<string> openid_list);
/// <summary>
/// 获取用户身上的标签列表
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="openid">用户OpenID</param>
/// <returns></returns>
List<int> GetIdList(string accessToken, string openid);
}

Let’s take a look at the official definition data of several interfaces.

1) Create tag interface

Interface call request description

http request method: POST (please use https protocol)

https://api.weixin.qq.com/cgi-bin/tags/create?access_token=ACCESS_TOKEN

POST data format: JSON

POST data example:

{
"tag" : {
"name" : "广东"//标签名
}
}

Copy after login

Return instructions (example of json data packet returned normally)

{
"tag":{
"id":134,//标签id
"name":"广东"
}
}

Copy after login

In this way we can define an entity class to carry the returned data.

/// <summary>
/// 标签信息
/// </summary>
public class TagJson
{
/// <summary>
/// 标签id，由微信分配
/// </summary>
public int id { get; set; }
/// <summary>
/// 标签名，UTF8编码
/// </summary>
public string name { get; set; }
}

Copy after login

In this way, the complete implementation code for creating tags is as follows

/// <summary>
/// 创建标签
/// 一个公众号，最多可以创建100个标签。
/// </summary>
/// <param name="accessToken">调用接口凭证</param>
/// <param name="name">标签名（30个字符以内）</param>
/// <returns></returns>
public TagJson CreateTag(string accessToken, string name)
{
var url = string.Format("https://api.weixin.qq.com/cgi-bin/tags/create?access_token={0}", accessToken);
var data = new
{
tag = new
{
name = name
}
};
var postData = data.ToJson();
var result = JsonHelper<TagCreateResult>.ConvertJson(url, postData);
return result != null ? result.tag : null;
}

Copy after login

2) Get the public Created tag

Interface call request description

http request method: GET (please use https protocol)

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

Return data format: JSON Returned data example:

{
"tags":[{
"id":1,
"name":"黑名单",
"count":0 //此标签下粉丝数
},{
"id":2,
"name":"星标组",
"count":0
},{
"id":127,
"name":"广东",
"count":5
}
]
}

Copy after login

In this way we can define its return value as List, where TagCountJson is an attribute of the corresponding class.

/// <summary>
/// 标签信息和统计数量
/// </summary>
public class TagCountJson : TagJson
{
/// <summary>
/// 此标签下粉丝数
/// </summary>
public int count { get; set; }
}

Copy after login

In this way, we can return the corresponding data through JSON parsing. The related operations are similar to the above interface and will not be described in detail.
