我会写在这里几乎完全“如何”引导来实现AJAX在Zendframework 3.调用 我们需要:
- 一个路由声明
- 控制器
- 一些JavaScript(是出skope的,也许我会在其他地方表现出来)
路线声明:
<?php
// editing a module.config.php in your project
// typical lines:
namespace Ajax2l; // my ajax module name
use Zend\Router\Http\Segment;
// ...
'router' => [
// ... other routes
'ajax2lsajaxcall' => [
'type' => Segment::class,
'options' => [
'route' => '/ajax2l/ajaxrequest[/:action][/:garbage]',
// the :action wildcard is a place to have extra parameters
// the :garbage wildcard is a place to send random strings
// to ensure you break cache to get real process for
// all your calls, since every call will be different
'defaults' => [
'controller' => Controller\AjaxController::class,
'action' => 'ajaxrequest'
]
],
'may_terminate' => true,
'child_routes' => [
// other ajax routes if needed
]
],
// I only use one ajax route and one controller for all my sites' ajax
// calls because they fire small db actions and reflect them on small
// parts of my pages. So I think I do not need a route and a controller
// for each ajax call. Instead, I use a Library and some services to get
// sets of elementary components and to perform tasks.
的控制器 我Ajax2l模块位于 “myzend_project /模块” 目录下。
<?php
// Filename: /module/Ajax2l/src/Controller/AjaxController.php
namespace Ajax2l\Controller
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
// No more components are needed
class AjaxController extends AbstractActionController {
public function ajaxrequestAction(){
$request = $this->getRequest();
$content = $request->getContent();
$isHttpRequest = $this->ifIsValidHttpRequest();
// if you have a real ajax call you must disable the normal output
$viewmodel = new ViewModel();
$viewmodel->setTerminal($is_xmlhttprequest);
// If not an Ajax call (perhaps from untrusted eyes) serve a forgiven
// page message
if(!$isHttpRequest){
return $this->forgivenPage();
}
// Now prepare a response and responds
$requestParams = $this->preProcessRequest($content);
// call the logics to process your params
$output = $this->processRequestParams($requestParams);
// and send a response
$response = $this->getResponse();
$response->setContent($output);
return $response;
}
private function ifIsValidHttpRequest($content){
// I use a small token string to verify if posted data matches
// perhaps not the proper way but is fast and works
$token = 'my_secure_visitor_session_token_identifier';
return (strpos($content, $token) > 2) ? 1 : 0;
// the validation is simplified here it has some more
// complex logics. To ensure validation of requesting source
}
private function preProcessRequest($content){
// The logics to know what to do
// ...
// here you can identify and set properly the post params
}
function processRequestParams($requestParams){
// some logics to process your data
// ...
// some logics to create a Json output
// ...
return $jsonObject;
}
protected function forgivenPage(){
$view = new ViewModel([]);
// set a forgiven message page as output
$view->setTemplate('ajax2l/messages/forgiven.phtml');
// note: the views directory uses lowercase for module names
return $view;
}
}
希望它有帮助。我失去了大量的时间阅读Zend Ajax没有结果。所以我希望我是最后一次在这个话题上失去时间。
