用于检查“授权"的 Zend Framework 1.12 插件标题

问题描述

我正在使用 Zend Framework 1.12 编写 REST api.我想检查控制器插件中的授权"标题.

I'm writing REST api using Zend Framework 1.12. I want to check "Authorization" header in controller plugin.

我把代码放在插件的preDispatch动作中

I put code in the preDispatch action of the plugin

$authorizationHeader    =   $request->getHeader('Authorization');
if(empty($authorizationHeader)) {
    $this->getResponse()->setHttpResponseCode(400);
    $this->getResponse()->setBody('Hello');
    die(); //It doesn't work
}

问题是在它之后控制器的动作仍然被调用.我试过死()"，退出".我的问题是如何从插件返回响应而不调用控制器的操作.

The problem is that after it controller's action is still being called. I tried 'die()', 'exit'. My question is how to return response from plugin and do not call controller's action.

推荐答案

几周前用这种方法用 Zend 做了一个类似的 REST API:

Did a similar REST API with Zend several weeks ago with this approach:

类变量/常量:

protected $_hasError = false;
const HEADER_APIKEY = 'Authorization';

我的预调度:

public function preDispatch()
{
    $this->_apiKey = ($this->getRequest()->getHeader(self::HEADER_APIKEY) ? $this->getRequest()->getHeader(self::HEADER_APIKEY) : null);

    if (empty($this->_apiKey)) {
        return $this->setError(sprintf('Authentication required!'), 401);
    }

    [...]

}

我的自定义 setError 函数:

My custom setError Function:

private function setError($msg, $code) {
    $this->getResponse()->setHttpResponseCode($code);
    $this->view->error = array('code' => $code, 'message' => $msg);
    $this->_hasError = true;

    return false;
}

然后只需检查您的函数中是否设置了错误:

Then simply check if a error has been set inside your functions:

public function yourAction()
{
    if(!$this->_hasError) {

    //do stuff

    }
}

如果您使用的是 contextSwitch 和 JSON，那么您的有错误的数组将被自动返回 &显示，如果发生错误:

If you're using contextSwitch and JSON, then your array with errors will be automatically returned & displayed, if an error occours:

public function init()
{
    $contextSwitch = $this->_helper->getHelper('contextSwitch');
    $this->_helper->contextSwitch()->initContext('json');

    [...]

}
