Access to APP source code: (please read the baby's instructions)

This APP is built on basic, upgrade, data and security chapters. You can only understand the source code after you have learned all these chapters!

If a user gets the source code and wants to quickly apply it to his or her own server, see this series of articles

First, set up a configuration MQTT server

1. In the basics section, install and configure an MQTT server

2. In the Security section, configure secure connections for MQTT

2. Install Configuration Database

1. In the data section, install the database

https://www.cnblogs.com/yangfengwu/category/1410242.html

In the cloud database, create a table named register with the database name login. The field names in the table are as follows

Third, set up and configure Apache server

1. In the upgrade section, install and configure the Apache server

4. Cloud Server Configuration Resolves Registered php Programs

1. Create a folder named LoginAndRegistration at the root of the page

Fifth, modify the address information of APP connections

1, modify the IP address of the registered login connection

2, Modify the information of the connected MQTT

3, the update configuration of APP (just place the update files and the updated installation packages where they can be accessed and downloaded from http or https)

1, Modify access to update files, according to your own modifications

The content of the updated file accessed

{ VerCode:5, VerName:1.2.1, Address:"http://www.mnif.cn/appapk/IotDevelopmentVersion/20190730/app-debug.apk", Details: "1,Add Customization MQTT Connect,Support TCP,SSL; 2,Binding devices can customize subscribed topics 3,Supports single switch control 4,Optimized communication monitor program " }
