Zend Framework中如何判断URL是否设置了转发
下面我来介绍一个Zend Framework中如何判断URL是否设置了转发,有需要学习的朋友可参考.
发送HTTP请求,代码如下:
<?php
$client = new Zend_Http_Client();
$client->setUri($url);
$client->setConfig(array(
'maxredirects' => 1
));
$response = $client->request();
if ($response->isRedirect()) {
echo "设置了转发";
} else {
echo "没有设置转发";
}
?>在这里如果不设置maxredirects参数,Zend默认的最大跳转数为5,就是在每次请求的时候,如果该地址设置了转发,他会读取转发到的新地址,然后再对这个地址发起请求,循环做这个操作,直至新地址没有设置转发或者循环超过了5次才会返回最后一次的请求数据.
这样的话,如果我只想获取某个域名是否设置了转发,那么就必须设置下maxredirects这个参数了.
Zend Framework代码如下:
<?php
public function request($method = null) {
if (!$this->uri instanceof Zend_Uri_Http) {
/** @see Zend_Http_Client_Exception */
require_once 'Zend/Http/Client/Exception.php';
throw new Zend_Http_Client_Exception('No valid URI has been passed to the client');
}
if ($method) {
$this->setMethod($method);
}
$this->redirectCounter = 0;
$response = null;
// Make sure the adapter is loaded
if ($this->adapter == null) {
$this->setAdapter($this->config['adapter']);
}
// Send the first request. If redirected, continue.
do {
// Clone the URI and add the additional GET parameters to it
//省略一万字
} while ($this->redirectCounter < $this->config['maxredirects']);
return $response;
}
