标题: 请教loadrunner Sockets协议接收报文为空问题
刚开始学习loadrunner11，简单编了个脚本，具体内容如下：
vuser_init()
{
lrs_startup(257);

return 0;
}

Action()
{

int rc=0;
rc = lrs_create_socket("socket0","TCP","LocalHost=0","RemoteHost=20.13.0.216:5555", LrsLastArg);//建立到服务端的连接
if (rc==0)
   lr_output_message("Socket  was successfully created ");
else
   lr_output_message("An error occurred while creating the socket, Error Code: %d", rc);
lrs_send("socket0", "buf0", LrsLastArg); //往"socket0"发送"buf0"中的数据

lrs_receive("socket0", "buf1", LrsLastArg);//将"socke0"中返回的数据存放到"buf1"中

   return 0;
}

vuser_end()
{
lrs_close_socket("socket0");
lrs_cleanup();

return 0;
}

data.ws内容如下：

;WSRData 2 1

send buf0 6

"123456"

recv buf1 6

-1

被测试程序可以成功接收到报文内容“123456”，返回的报文不能成功接收，从loadrunner的日志中显示0 bytes were received；被测试程序逻辑很简单，就是接收到的报文原样返回。各位大侠请帮忙看看？

脚本执行后的日志如下：
