- Update the login function .Consider more secure factors like sql injection

  ### **Before**:

  When i come to login interface in the old version without thinkphp ,I input "admin' AND 1=1 -- " into the username blank and input any other text into password blank even though that is a wrong password. It will show like this:

  ### Now:

  Input the same as above step,then the thinkphp framework will filter the user input then show like this:

  But to a certain extent,ThinkPHP may also have some vulnerable bugs  leading to be hacked.

# How did you implement it/them?

-  **IOT/webMonitor/thinkphp v5/thinkphp5/application/index/controller/Login.php**

  ```
  <?php
  namespace app\index\controller;
  use think\Controller;
  use think\Cookie;
  class Login extends Controller
  {
      public function index()
      {
      	return $this->fetch();
      }   
      public function login()
      {
      	$post_data = input('post.');
      	$username = $post_data['username'];
      	$password = $post_data['password'];
      	if(empty($username))
      	{
      		$this->error('please input username');
      	}
      	if(empty($password))
      	{
      		$this->error('please input password');
      	}
      	$valid = db('user')->where('username', $username)->find();
      	if(empty($valid)){
      		
      		$this->error('username or password error!');
      	}
      	if($valid['password'] != md5($password)){
      		
      		$this->error('username or password error!');
      	}
      	cookie('username', $valid['username'], 3600);
      	$this->redirect(url('index/index'));
      }
  }
  ```

  When do some mysql operation , use the ThinkPHP internal sql function to realize the login function.

  ```
  db('user')->where('username', $username)->find()
  ```

-  **IOT/webMonitor/thinkphp v5/thinkphp5/application/index/controller/Sensorsdata.php**

  ```
  <?php
  namespace app\index\controller;
  use think\Controller;
  use think\Cookie;
  class Sensorsdata extends Controller
  {
      public function index()
      {
          if(cookie::has('username'))
          {
              $ID = 0;
              $dataset = db('device')->where('ID', $ID)->find();
              $data_airQuality = $dataset['data_airQuality'];
              $data_distance = $dataset['data_distance'];
              $data_voice = $dataset['data_voice'];
              $data_light = $dataset['data_light'];
              $data_humi = $dataset['data_humi'];
              $data_temp = $dataset['data_temp'];
              $data = array(
                  'temp'=>$data_temp, 
                  'humi'=>$data_humi,
                  'light'=>$data_light, 
                  'voice'=>$data_voice,
                  'airquality'=>$data_airQuality, 
                  'distance'=>$data_distance
              );
              return json_encode($data);
          }
              
              // return $this->fetch();
          else
          {
              $this->error('Please login first');
              $this->redirect(url('login/index'));
          }
             
      }   
  }
  ```

  Get sensors data in real time from the ESP8266 hardware and send them to the web UI.

- **Split frontend and backend**

  The project list is as below:

  - controller
    - Index,php
    - Login.php
    - Sensorsdata.php
  - view
    - index
      - index.html
    - login
      - index.html

## Roadmap

- Considering when the IOT system is used into actual, there are many devices instead of one of two .So it is necessary to add a devices manager function  to help use it Conveniently.
- Identify different devices by their ID
- Consider the performance of the communication protocol .May use MQTT protocol in the future version.
- Add other control way like discord controlling .
