PHPCURL直接访问JSONRPC服务

 <?php
 $ch = curl_init();
 $url = 'http://localhost/jsonrpc?tm='.time().mt_rand (100,999); //参数是为了防止缓存
 $options = array(
     CURLOPT_URL => $url,
     CURLOPT_USERAGENT => "Mozilla/5.0 (Windows NT 6.1; rv:12.0) Gecko/20100101 Firefox/12.0",
     CURLOPT_RETURNTRANSFER => 1,
     );
 curl_setopt_array($ch, $options);
 #JSON 示例数据
 curl_setopt($ch, CURLOPT_POSTFIELDS, '{"jsonrpc":"2.0","method":"getOpt","id":1}'); 

 $html=curl_exec($ch);
 $info = curl_getinfo($ch);            #获取请求的详细信息 用于调试
 curl_close($ch);
 var_dump($html);

注意CURLOPT_POSTFIELDS是不能http_build_query的，注意这点和普通的POST数据不一样，这里类似文件上传
