M?veletek

A m?veletek felel?sek a modul '¨¹zleti logik¨¢j¨¢¨¦rt'. Egy m?velet ¨¢ltal¨¢ban egy ±¹±ð³ú¨¦°ù±ô?²ú?±ô ¨¦s egy m?velet n¨¦zetb?l ¨¢±ô±ô.

Egy modul k¨¦pes:

• A Áú»¢¶Ä²© kezel?fel¨¹let¨¦n m¨¢r meghat¨¢rozott m?veletek megh¨ªv¨¢s¨¢ra.
• Az alap¨¦rtelmezett m?veletek fel¨¹lb¨ªr¨¢l¨¢s¨¢ra egy¨¦ni m?veletekkel.
• Teljesen ¨²j m?veletek meghat¨¢roz¨¢s¨¢ra.

Egy alap¨¦rtelmezett m?veleti viselked¨¦s bizonyos egy¨¦ni viselked¨¦ssel t?rt¨¦n? fel¨¹lb¨ªr¨¢l¨¢s¨¢hoz adjon meg egy azonos nev? m?veletet a modulkonfigur¨¢ci¨®ban. A m?velet megh¨ªv¨¢sakor a modulm?velet ker¨¹l v¨¦grehajt¨¢sra az alap¨¦rtelmezett Áú»¢¶Ä²© m?velet helyett.

A m?veletf¨¢jlokat az actions mapp¨¢ban kell t¨¢rolni. A m?veleteket a manifest.json f¨¢jlban kell megadni.

Controller

Action controller workflow:

1. Check that all parameters passed in an HTTP request are valid:

• Call the controller's checkInput() method
• Use validation rules defined in CNewValidator.php
• Call validateInput() method

2. Check user permissions.

3. Prepare the data according to passed parameters: if checkInput() returns true, Áú»¢¶Ä²© calls the controller's doAction() method.

4. Prepare the $data array for the view. Use CControllerResponseData and setResponse() method to store response in the $data array.

Example:

/**
        * Validate input parameters.
        *
        * @return bool
        */
       protected function checkInput(): bool {
           $ret = $this->validateInput([
               'status' => 'in '.implode(',', [HOST_STATUS_MONITORED, HOST_STATUS_NOT_MONITORED])
           ]);
       
           if (!$ret) {
               $this->setResponse(new CControllerResponseFatal());
           }
       
           return $ret;
       }
       
       /**
        * Check user permissions.
        *
        * @return bool
        */
       protected function checkPermissions() {
           return $this->getUserType() >= USER_TYPE_ZABBIX_ADMIN;
       }
       
       /**
        * Execute action and generate response object.
        */
       protected function do Action(): void {
           $data = [ 
               'hosts_count' => API::Host()->get([
                   'countOutput' => true,
                   'filter' => [
                       'status' => $this->getInput('status')
                   ]
               ]) 
           ];
           
           $this->setResponse(new CControllerResponseData($data));
       }
