Cakephp .json ext 给出缺少的方法
Cakephp .json ext giving Missing Method
我有一个下拉菜单 onChange 我使用 ajax 从控制器中的方法加载一些 .json。
但是我得到 error 404 returned
如果我删除 .json 扩展名，我会得到 error 500 缺少的模板，我也无法解决。我尝试了不同的解决方案。我宁愿使用 .json 分机，让 cakephp return 格式正确 JSON.
Missing Method in StrategiesConditionsController
Cake\Controller\Exception\MissingActionException
Error The action conditions.json is not defined in StrategiesConditionsController
Create StrategiesConditionsController::conditions.json() in file: src/Controller/StrategiesConditionsController.php.
通过多次阅读文档，我确信我的路线是正确的。
