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 => '', ), ),
<?php/** * Curl wrapper for Yii * @author hackerone */class Curl extends CComponent{ private $_ch; private $response; // config from config.php public $options; // default config private $_config = array( CURLOPT_RETURNTRANSFER => true, CURLOPT_FOLLOWLOCATION => true, CURLOPT_HEADER => false, CURLOPT_VERBOSE => true, CURLOPT_AUTOREFERER => true, CURLOPT_CONNECTTIMEOUT => 30, CURLOPT_TIMEOUT => 30, CURLOPT_SSL_VERIFYPEER => false, CURLOPT_USERAGENT => 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)' ); private function exec($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); } /** * Curl 原生post请求发送方式 * * 用于需要post无key参数、post文件等 */ public function post($url, $data = array()) { $this->setOption(CURLOPT_POST, true); $this->setOption(CURLOPT_POSTFIELDS, $data); return $this->exec($url); } public function put($url, $data, $params = array()) { // write to memory/temp $f = fopen('php://temp', 'rw+'); fwrite($f, $data); rewind($f); $this->setOption(CURLOPT_PUT, true); $this->setOption(CURLOPT_INFILE, $f); $this->setOption(CURLOPT_INFILESIZE, strlen($data)); return $this->exec($this->buildUrl($url, $params)); } public function delete($url, $params = array()) { $this->setOption(CURLOPT_RETURNTRANSFER, true); $this->setOption(CURLOPT_CUSTOMREQUEST, 'DELETE'); return $this->exec($this->build/本2文来源[email protected]搞@^&代*@码2网搞gaodaima代码Url($url, $params)); } public function buildUrl($url, $data = array()) { $parsed = parse_url($url); isset($parsed['query']) ? parse_str($parsed['query'], $parsed['query']) : $parsed['query'] = array(); $params = isset($parsed['query']) ? array_merge($parsed['query'], $data) : $data; $parsed['query'] = ($params) ?
