Cakephp获取有关安全组件错误的详细信息

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

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.

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.
