Magento curl 的使用

最近在处理magento接口的curl，直接贴代码吧

$curl = new Varien_Http_Adapter_Curl();//调用magento的curl
$curl->setConfig(array('timeout'   => 1));//配置，可略过
$curl->write(Zend_Http_Client::POST, $url, '1.0','',http_build_query($data));//post
$data = $curl->read();//返回数据
$curl->close();//清除curl
return $data;

核心代码相关,方便参考 lib\Varien\Http\Adapter\Curl.php

    /**
     * Set the configuration array for the adapter
     *
     * @param array $config
     * @return Varien_Http_Adapter_Curl
     */
    public function setConfig($config = array())
    {
        $this->_config = $config;
        return $this;
    }

    /**
     * Send request to the remote server
     *
     * @param string        $method
     * @param Zend_Uri_Http $url
     * @param string        $http_ver
     * @param array         $headers
     * @param string        $body
     * @return string Request as text
     */
    public function write($method, $url, $http_ver = '1.1', $headers = array(), $body = '')
    {
        if ($url instanceof Zend_Uri_Http) {
            $url = $url->getUri();
        }
        $this->_applyConfig();

        // set url to post to
        curl_setopt($this->_getResource(), CURLOPT_URL, $url);
        curl_setopt($this->_getResource(), CURLOPT_RETURNTRANSFER, true);
        if ($method == Zend_Http_Client::POST) {
            curl_setopt($this->_getResource(), CURLOPT_POST, true);
            curl_setopt($this->_getResource(), CURLOPT_POSTFIELDS, $body);
        }
        elseif ($method == Zend_Http_Client::GET) {
            curl_setopt($this->_getResource(), CURLOPT_HTTPGET, true);
        }

        if (is_array($headers)) {
            curl_setopt($this->_getResource(), CURLOPT_HTTPHEADER, $headers);
        }

        /**
         * @internal Curl options setter have to be re-factored
         */
        $header = isset($this->_config['header']) ? $this->_config['header'] : true;
        curl_setopt($this->_getResource(), CURLOPT_HEADER, $header);

        return $body;
    }

    /**
     * Read response from server
     *
     * @return string
     */
    public function read()
    {
        $response = curl_exec($this->_getResource());

        // Remove 100 and 101 responses headers
        while (Zend_Http_Response::extractCode($response) == 100 || Zend_Http_Response::extractCode($response) == 101) {
            $response = preg_split('/^\r?$/m', $response, 2);
            $response = trim($response[1]);
        }

        if (stripos($response, "Transfer-Encoding: chunked\r\n")) {
            $response = str_ireplace("Transfer-Encoding: chunked\r\n", '', $response);
        }

        return $response;
    }

    /**
     * Close the connection to the server
     *
     * @return Varien_Http_Adapter_Curl
     */
    public function close()
    {
        curl_close($this->_getResource());
        $this->_resource = null;
        return $this;
    }

下面贴一个php原生的curl的方法，其实magento封装的和原生的原理都是一样的

    /**
     * curl request data for carrier
     */
    public function curlPost($url, $post_data = array(), $timeout = 10, $header = "", $data_type = "",$param_type = '') {
        $header = empty($header) ? '' : $header;
        //支持json数据数据提交
        if($data_type == 'json'){
            $post_string = json_encode($post_data);
        }elseif($data_type == 'array') {
            $post_string = $post_data;
        }elseif(is_array($post_data)){
            $post_string = http_build_query($post_data, '', '&');
        }

        $ch = curl_init();    // 启动一个CURL会话
        curl_setopt($ch, CURLOPT_URL, $url);     // 要访问的地址
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);  // 对认证证书来源的检查   // https请求 不验证证书和hosts
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);  // 从证书中检查SSL加密算法是否存在
        curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // 模拟用户使用的浏览器
        //curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转
        //curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer
        if(strtolower($param_type) == 'post'){
            curl_setopt($ch, CURLOPT_POST, true); // 发送一个常规的Post请求
            curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);     // Post提交的数据包
        }
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);     // 设置超时限制防止死循环
        curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
        //curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     // 获取的信息以文件流的形式返回
        curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //模拟的header头
        $result = curl_exec($ch);

        // 打印请求的header信息
        //$a = curl_getinfo($ch);
        //var_dump($a);

        curl_close($ch);
        return $result;
    }
