cakePHP 3.0操作PagesController :: myaction.json()找不到，或无法访问. [英] cakePHP 3.0 Action PagesController::myaction.json() could not be found, or is not accessible."
问题描述
我正在将现有的2.5应用程序迁移到3.0.使用ajax时出现404错误.在cakePHP 2.5中可以正常工作
I am migrating an existing 2.5 app over to 3.0. I am getting an 404 error when using ajax. This works fine in cakePHP 2.5
url:"/cakephp3/pages/myaction.json"
url: "/cakephp3/pages/myaction.json"
我看不到我可能错过的任何步骤.
I don't see any step that I might have missed.
我确定这是扩展名为.json的路由问题
I am sure it is a routing issue with the .json extension
routes.php
routes.php
Router::scope('/', function ($routes) {
Router::extensions(['json', 'xml']);
$routes->connect('/', ['controller' => 'Pages', 'action' => 'home']);
$routes->connect('/hotel-training-courses', ['controller' => 'pages', 'action' => 'trainingCourses']);
$routes->connect('/feature-tour', ['controller' => 'pages', 'action' => 'features']);
$routes->connect('/contact-us', ['controller' => 'pages', 'action' => 'contact']);
$routes->fallbacks('InflectedRoute');
});
PagesController.php
PagesController.php
public function initialize()
{
parent::initialize();
$this->loadComponent('RequestHandler');
}
public function myaction(){
$this->request->onlyAllow('ajax');
$userName = $this->request->data['name'];
$userCompany = $this->request->data['company'];
$userEmail = $this->request->data['email'];
$userPhone = $this->request->data['phone'];
//send an email
}
先前的应用程序能够检测到请求类型并以相同的类型返回.无需设置渲染.
The previous app was able to detect the request type and return with the same type. There was no need to set the render.
推荐答案
全局扩展必须在范围之外定义
Router :: extensions()必须放置在外部，以防应应用于所有路由，请在定义任何作用域和路由之前调用.
Global extensions must be defined outside of scopes
Router::extensions() must be placed outside of, and in case it should apply to all routes, invoked before defining any scopes and routes.
如果要将扩展名解析限制在特定范围内，请使用 RouteBuilder :: extensions()，即任一
In case you want to restrict extension parsing to a specific scope, use RouteBuilder::extensions(), ie either
Router::extensions(['json', 'xml']);
Router::scope('/', function (RouteBuilder $routes) {
$routes->connect('/', ['controller' => 'Pages', 'action' => 'home']);
//...
});
或
Router::scope('/', function (RouteBuilder $routes) {
$routes->extensions(['json', 'xml']);
$routes->connect('/', ['controller' => 'Pages', 'action' => 'home']);
//...
});

Request :: onlyAllow()已重命名为 Request :: allowMethod()，所以这是您遇到的下一个问题.
Request::onlyAllow() has been renamed to Request::allowMethod(), so that's the next problem that you'll encouter.

还应该启用调试模式，以便收到有意义的错误消息，其中包含调试此类问题所必需的适当详细信息.
Also you should enable debug mode so that you receive meaningful error messages with the appropriate details, necessary to debug such problems.
