我在我的项目中使用安全组件,有没有办法在开发时获得有关错误的详细描述？例如： – 如果在视图中添加任何字段而不使用cakePHP的form方法,则在blackHoleCallback函数中返回错误为’auth’.相反,我需要因为它返回错误的原因.因为要花很多时间来纠正这个问题.有没有办法得到详细的错误描述？
您所要做的就是在正确的地方寻找
原文链接：https://www.f2er.com/php/134343.html检查app / tmp / logs / error.log文件
如果您查看错误日志,您将看到如下条目：
2013-03-16 17:24:29 Error: [BadRequestException] The request has been black-holed #0 root/lib/Cake/Controller/Component/SecurityComponent.PHP(228): SecurityComponent->blackHole(Object(FacebookUsersController),'csrf') #1 [internal function]: SecurityComponent->startup(Object(FacebookUsersController)) #2 root/lib/Cake/Utility/ObjectCollection.PHP(130): call_user_func_array(Array,Array) #3 [internal function]: ObjectCollection->trigger(Object(CakeEvent)) #4 root/lib/Cake/Event/CakeEventManager.PHP(246): call_user_func(Array,Object(CakeEvent)) #5 root/lib/Cake/Controller/Controller.PHP(670): CakeEventManager->dispatch(Object(CakeEvent)) #6 root/lib/Cake/Routing/Dispatcher.PHP(183): Controller->startupProcess() #7 root/lib/Cake/Routing/Dispatcher.PHP(161): Dispatcher->_invoke(Object(FacebookUsersController),Object(CakeRequest),Object(CakeResponse)) #8 root/app/webroot/index.PHP(96): Dispatcher->dispatch(Object(CakeRequest),Object(CakeResponse)) #9 {main}
阅读屏幕上的错误
如果处于调试模式,则错误发生时屏幕上也会显示此错误.例如.：
The request has been black-holed Error: The requested address '/admin/fooby/edit/1' was not found on this server. Stack Trace CORE/Cake/Controller/Component/SecurityComponent.PHP line 228 → SecurityComponent->blackHole(FacebookUsersController,string) [internal function] → SecurityComponent->startup(FacebookUsersController) CORE/Cake/Utility/ObjectCollection.PHP line 130 → call_user_func_array(array,array) [internal function] → ObjectCollection->trigger(CakeEvent) CORE/Cake/Event/CakeEventManager.PHP line 246 → call_user_func(array,CakeEvent) CORE/Cake/Controller/Controller.PHP line 670 → CakeEventManager->dispatch(CakeEvent) CORE/Cake/Routing/Dispatcher.PHP line 183 → Controller->startupProcess() CORE/Cake/Routing/Dispatcher.PHP line 161 → Dispatcher->_invoke(FacebookUsersController,CakeRequest,CakeResponse) APP/webroot/index.PHP line 96 → Dispatcher->dispatch(CakeRequest,CakeResponse)
处理csrf错误
通过特定错误的详细信息(即您发布的数据以及当时会话中的确切令牌数据),可以回答问题所带来的问题,因为没有错误：
看看抛出错误的那一行.
在上面的堆栈跟踪中,错误来自CORE / Cake / Controller / Component / SecurityComponent.PHP第228行 – 打开文件并查看该代码是什么：
if ($isPost && $isNotRequestAction && $this->csrfCheck) {
if ($this->_validateCsrf($controller) === false) {
return $this->blackHole($controller,'csrf');
}
}
从中可以明显看出,函数_validateCsrf负责请求被黑洞化.这不应该是一个惊喜.
看看那个函数的来源：
protected function _validateCsrf(Controller $controller) {
$token = $this->Session->read('_Token');
$requestToken = $controller->request->data('_Token.key');
if (isset($token['csrfTokens'][$requestToken]) && $token['csrfTokens'][$requestToken] >= time()) {
if ($this->csrfUSEOnce) {
$this->Session->delete('_Token.csrfTokens.' . $requestToken);
}
return true;
}
return false;
}
根据该函数返回false的原因,确定继续调试的方式.
正确配置组件
调试CSRF错误的必然结果是您需要修改configuration of the Security component.
例如,您是否想要重复使用令牌,因为您的应用在页面加载之间多次提交相同的表单？
您是否通过向表单数据添加新字段来自动使表单请求失效 – 您可以使用the unlockedFields property从csrf检查中排除这些字段.
你也可以简单地完成disable CSRF checks.这有明显的安全后果 – 但如果您正在努力使用该组件,那么这是一种简单的解决方法,也是您目前遇到的问题.
