Thinkphp controller scheduling example

Thinkphp controller scheduling example

This article mainly introduces the example of thinkphp controller scheduling. For more information, see

1. How to obtain the module name and controller name through the address bar parameters (even if there is a route and a rewrite module is enabled)

 

2. How does tp implement the pre-and post-method functional modules and how does it execute methods with parameters?

 

The ReflectionClass and reflemethod method class provided by the php system can reflect attributes of user-defined classes, permissions of methods, parameters, and other information. Through this information, you can accurately control the execution of methods.

 

ReflectionClass mainly uses the following methods:

HasMethod (string) whether a method exists

GetMethod (string)

 

ReflectionMethod:

GetNumberOfParameters ()

GetParamters () Get parameter information

 

3. Code demonstration

 

The Code is as follows:

<? Php

Class IndexAction {

Public function index (){

Echo 'index'. "rn ";

}

Public function test ($ year = 2012, $ month = 2, $ day = 21 ){

Echo $ year. '--------'. $ month. '-----------'. $ day. "rn ";

}

Public function _ before_index (){

Echo _ FUNCTION _. "rn ";

}

Public function _ after_index (){

Echo _ FUNCTION _. "rn ";

}

}

 

// Execute the index Method

$ Method = new ReflectionMethod ('indexaction', 'index ');

// Determine Permissions

If ($ method-> isPublic ()){

$ Class = new ReflectionClass ('indexaction ');

// Execute the pre-Method

If ($ class-> hasMethod ('_ before_index ')){

$ BeforeMethod = $ class-> getMethod ('_ before_index ');

If ($ beforeMethod-> isPublic ()){

$ BeforeMethod-> invoke (new IndexAction );

}

}

 

$ Method-> invoke (new IndexAction );

 

// Execute the POST method

If ($ class-> hasMethod ('_ after_index ')){

$ BeforeMethod = $ class-> getMethod ('_ after_index ');

If ($ beforeMethod-> isPublic ()){

$ BeforeMethod-> invoke (new IndexAction );

}

}

}

 

 

// Execute the method with Parameters

$ Method = new ReflectionMethod ('indexaction', 'test ');

$ Params = $ method-> getParameters ();

Foreach ($ params as $ param ){

$ ParamName = $ param-> getName ();

If (isset ($ _ REQUEST [$ paramName])

$ Args [] =$ _ REQUEST [$ paramName];

Elseif ($ param-> isDefaultValueAvailable ())

$ Args [] = $ param-> getDefaultValue ();

}

If (count ($ args) ==$ method-> getNumberOfParameters ())

$ Method-> invokeArgs (new IndexAction, $ args );

Else

Echo 'parameters is not match! ';
