curl要注意的几点

1.post提交数据

$postData = array(
                'paramCity' => array(array('id' => $city_id, 'day' => $city_days, 'name' => $city_name)),
                'paramAttr' => $paramAttr,
                'paramBiqu' => $must_go ? $must_go['param_value'] : ,    //必去控制
                'paramPlayRhythm' => $rhythm ? $rhythm['param_value'] : ,    //行程控制
                'paramBudget' => $budget ? $budget['param_value'] : ,    //预算控制
                'paramSelectedLocation' => '',
                'paramSelectedFood' => ,    //美食控制
                'paramNeedFood' => ,    //美食控制
                'paramNeedBar' => ,    //酒吧控制
                'paramDateSetting' => array('start_date' => $start_time, 'end_date' => $end_time),
                'paramCurTripId' => ,    //首次游等种类的选择控制,
                'is_control' =>     //是网页一步一步操作还是通过工具        1:人工控制
            );

提交的话，用http_build_query组装即可。

curl_setopt($ch, CURLOPT_POST, count($postData));//post提交方式
            curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));

            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, );
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            $result = curl_exec($ch);
            $errorCode = curl_errno($ch);
            curl_close($ch);

            print_r($result);exit;

            if( !== $errorCode) {
                echo 'failed';exit;
            } else {
                echo 'success';exit;
            }

2.如果要继续保持本站session的调用，要加上如下的语句

 session_start();
 session_write_close();
 curl_setopt($ch,CURLOPT_COOKIE,session_name().'='.session_id());    //保持继续能读取session
