In addition New users scan the QR code with parameters to follow the method: DoCodeNotSub.

1. Users follow the official account and return text messages and user records:

Assign values to the message model based on the parsed XML reflection. Now make user judgment:

tb_User mUser =DALWei.InfoEntities<tb_user>(dbHome,u=>u.OpenId==mSub.FromUserName);
            if (mUser != null)
            {
                  //说明此用户以前关注过后来取消了
            }
            else
            {
                 //全新的用户，添加
            ｝</tb_user>

The complete method code is as follows:

tb_User mUser =DALWei.InfoEntities<tb_user>(dbHome,u=>u.OpenId==mSub.FromUserName);
            if (mUser != null)
            {

                if (mUser.State == 0)
                {
                    SText mStxt = new SText();
                    mStxt.ToUserName = mSub.FromUserName;
                    mStxt.FromUserName = mSub.ToUserName;
                    mStxt.CreateTime = mSub.CreateTime;
                    mStxt.Content = "很抱歉，您已经被系统拒绝服务，若有疑问请联系我们";
                    DALWei.SendText(mStxt);
                    return;
                }
                else
                {
                    mUser.SubTime = DateTime.Now;
                    DALWei.UpdateEntity(dbHome, mUser);
                }
            }
            else
            {
                mUser = new tb_User();
                mUser.InId = 0;
                mUser.OpenId = mSub.FromUserName;
                mUser.GroupId = 0;
                mUser.NickName = "";
                mUser.CreateTime = System.DateTime.Now;
                mUser.State = 1;
                mUser.PreFirst = "";
                mUser.SubTime = DateTime.Now;
                DALWei.AddEntity(dbHome,mUser);
            
            }</tb_user>

Modify the user's last attention time if it already exists, and add a new user if it does not exist; where the user needs to be considered if the user already exists In the case of state=0, that is, the user is disabled, a text message will be returned directly, indicating that the user has been disabled.

2. Reply to text message

The encapsulated sending text message model SText can be assigned and output :

SText mStxtA = new SText();
            mStxtA.ToUserName = mSub.FromUserName;
            mStxtA.FromUserName = mSub.ToUserName;
            mStxtA.CreateTime = mSub.CreateTime;
            mStxtA.Content =ReadXml.Menu();
            Often.ResponseToEnd(DALWei.SendText(mStxtA));

Copy after login

Among them, the ReadXml.Menu() method returns a default segment of characters, which is used as a normal text menu (there will be a custom menu later).

The text is as follows:

public static string  Menu()
        {
            string Content = "";
            Content += "欢迎使用/微笑\n\n";
            Content += "输入以下序号开始获取最新信息：\n";
            Content += "1,企业快报\ue102\n";
            Content += "2,行业要览\n";
            Content += "3,行情动态\n";
            Content += "4,焦点访谈\n";
