The previous article has encapsulated all the messages and processed them in their own ways. This article starts with the first step of using - following. After following, the message will be recorded and text messages will be replied to the user. The following method: DoSub. 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)
????????????{
??????????????????//說明此用戶以前關(guān)注過后來取消了
????????????}
????????????else
????????????{
?????????????????//全新的用戶，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，您已經(jīng)被系統(tǒng)拒絕服務(wù)，若有疑問請(qǐng)聯(lián)系我們";
????????????????????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));

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?+=?"歡迎使用/微笑\n\n";
????????????Content?+=?"輸入以下序號(hào)開始獲取最新信息：\n";
????????????Content?+=?"1,企業(yè)快報(bào)\ue102\n";
????????????Content?+=?"2,行業(yè)要覽\n";
????????????Content?+=?"3,行情動(dòng)態(tài)\n";
????????????Content?+=?"4,焦點(diǎn)訪談\n";
????????????Content?+=?"5,下游資訊\n";
????????????Content?+=?"6,資訊中心\ue135\n";
????????????Content?+=?"7,采購\ue42f\n";
????????????Content?+=?"8,市場(chǎng)報(bào)告--VIP\ue035專屬\n\n";
????????????Content?+=?"輸入其他關(guān)鍵字可以搜索\ue114\n";
????????????Content?+=?"輸入序號(hào)@關(guān)鍵字可以在指定類別下搜索，比如?1@馬航\n";
????????????Content?+=?"輸入?或幫助?可以顯示此菜單";
????????????return?Content;
????????}
