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(
    &#39;maxredirects&#39; => 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 &#39;Zend/Http/Client/Exception.php&#39;;
        throw new Zend_Http_Client_Exception(&#39;No valid URI has been passed to the client&#39;);
    }
    if ($method) {
        $this->setMethod($method);
    }
    $this->redirectCounter = 0;
    $response = null;
    // Make sure the adapter is loaded
    if ($this->adapter == null) {
        $this->setAdapter($this->config[&#39;adapter&#39;]);
    }
    // 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[&#39;maxredirects&#39;]);
    return $response;
}
?>
