Yii框架灵活的扩展受到公司的青睐，所以，项目中使用了yii，为了兼容原来的系统，依然选择了yii1.1的版本。
这里不讲yii的特性，主要说一说使用yii时对curl的再次封装。
先看看yii的配置文件，在main.php中将curl配置为Components。
'components' => array(
// Curl库 调用：Yii::app()->curl
'curl' => array(
'class' => 'ext.curl.Curl',
'options' => array(
CURLOPT_HTTPHEADER => array('Expect:'),
CURLOPT_HEADER => '',
),
),
true,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HEADER => false,
CURLOPT_VERBOSE => true,
CURLOPT_AUTOREFERER => true,
CURLOPT_CONNECTTIMEOUT => 30,
CURLOPT_TIMEOUT => 30,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_USERAGENT => 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)'
);
private function exec($url)
{
$this->setOption(CURLOPT_URL, $url);
$this->response = curl_exec($this->_ch);
if (!curl_errno($this->_ch)) {
if (isset($this->options[CURLOPT_HEADER]))
if ($this->options[CURLOPT_HEADER]) {
$header_size = curl_getinfo($this->_ch, CURLINFO_HEADER_SIZE);
return substr($this->response, $header_size);
}
return $this->response;
} else {
throw new CException(curl_error($this->_ch));
return false;
}
}
public function get($url, $params = array())
{
$this->setOption(CURLOPT_HTTPGET, true);
return $this->exec($this->buildUrl($url, $params));
}
/**
* weimob 内部接口post请求专用
*
* 支持多维数组 和 文件上传
*
*/
public function httpPostRequest($url,$data = array()){
$this->setOption(CURLOPT_POST, true);
$this->setOption(CURLOPT_POSTFIELDS, http_build_query($data));
return $this->exec($url);
}
/**

*/
public function post($url, $data = array())

$this->setOption(CURLOPT_POSTFIELDS, $data);
return $this->exec($url);
}

$parsed['query'] = ($params) ? '?' . http_build_query($params) : '';
if (!isset($parsed['path'])) {
$parsed['path']='/';
}
$parsed['port'] = isset($parsed['port'])?':'.$parsed['port']:'';
return $parsed['scheme'].'://'.$parsed['host'].$parsed['port'].$parsed['path'].$parsed['query'];
}
public function setOptions($options = array())
{
curl_setopt_array($this->_ch, $options);

// close curl on exit
@Yii::app()->onEndRequest = function() use(&$ch){
curl_close($ch);

} catch (Exception $e) {
throw new CException('Curl not installed');
}
}
public function getHeaders()
