EXEU通過argv把客戶數(shù)據(jù)傳遞代碼值

1、 處里客戶端發(fā)來的請求，其中數(shù)值計(jì)算邏輯可執(zhí)行程序比如EXEU 通過argv把客戶數(shù)據(jù)傳遞過去，獲得計(jì)算結(jié)果返回客戶端 socket->async_write_some(buffer(respData),boost:bind(&this_type:write_handler,this,boost:asio:placeholders:error); else/如果客戶端不發(fā)送數(shù)據(jù)包結(jié)束后綴，會(huì)造成接收的數(shù)據(jù)包無限增大，加入數(shù)據(jù)自動(dòng)廢棄功能 if(recvData.size()>255) recvData.clear(); socket->async_write_some

2、(buffer("data is too long,auto delete."),boost:bind(&this_type:write_handler,this,boost:asio:placeholders:error); else/為收到完整數(shù)據(jù)包，繼續(xù)接收數(shù)據(jù) socket->async_read_some(buffer(m_buf),bind(&this_type:read_handler,this,boost:asio:placeholders:error,boost:asio:placeholders:bytes_transferred)
