WeChat public platform development: advanced interface description

The advanced interface mentioned here refers to the advanced functions opened for certified service accounts.

Advanced functions can be roughly classified as:

User interface

Group interface

Customer service interface (different from the multi-customer service introduced before)

Group sending interface

Multimedia interface

QR code interface

Template message interface (not all accounts can be activated)

OAuth2.0（ It is relatively complicated and will be introduced later)

All the above interfaces are included in the Senparc.Weixin.MP.AdvancedAPIs namespace.

Some common operations

Almost all high-level interfaces require AccessToken for communication (note that the following interfaces without special instructions require this AccessToken, but not all), so most There will be an AccessToken parameter passed in. For information on how to obtain and operate AccessToken, see Senparc.Weixin.MP SDK WeChat Public Platform Development Tutorial (8): General Interface Description.

Customer Service Interface

Explain , the customer service interface here is different from the previous "multi-customer service". The multi-customer service introduced before switches the user conversation status to multi-customer service, and the message is sent to a dedicated multi-customer service client. This conversation is initiated by the user. of. The "customer service" here actually refers to actively pushing messages to designated users at any time (the users have interacted within 48 hours), and the conversation does not need to be initiated by the user.

QR code interface

Use the QR code interface to easily create and verify QR codes. The QR code created is used to allow the user to focus on or identify the scene being scanned.

Source file folder: Senparc.Weixin.MP/AdvancedAPIs/QrCode

The relevant methods in the source code are as follows:

namespace Senparc.Weixin.MP.AdvancedAPIs
{
    //API：http://mp.weixin.qq.com/wiki/index.php?title=%E7%94%9F%E6%88%90%E5%B8%A6%E5%8F%82%E6%95%B0%E7%9A%84%E4%BA%8C%E7%BB%B4%E7%A0%81

Template message interface

Template Messages are similar to SMS notifications. They follow a certain template format (different from graphic and text messages) and cannot be obtained by every verified service account.

Source file folder: Senparc.Weixin.MP/AdvancedAPIs/TemplateMessage

The relevant methods in the source code are as follows:

namespace Senparc.Weixin.MP.AdvancedAPIs
{
    /// <summary>
    /// 模板消息接口
    /// </summary>
    public static class Template
    {
        public static WxJsonResult SendTemplateMessage<T>(string accessToken, string openId, string templateId, string topcolor, T data)
        {
            const string urlFormat = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token={0}";
            var msgData = new TempleteModel()
            {
                template_id = templateId,
                topcolor = topcolor,
                touser = openId,
                data = data
            };
            return CommonJsonSend.Send<WxJsonResult>(accessToken, urlFormat, msgData);
        }
    }
}

OAuth2.0 interface

The OAuth interface is used to securely verify the identity of users accessed using the WeChat embedded browser (such as obtaining OpenId)

Source file folder: Senparc.Weixin.MP/AdvancedAPIs/OAuth

Compared Other interfaces OAuth2.0 are slightly complicated
