socket 做唔做到限制對方每次的data size

專業收買佬

我個server好肯定每次都唔會收超過300byte....
node 亦都有寫
socket.on(data, err){
     console.log(data.toString());
     let len = data.length,
     if (len > 300){
           socket.close()
     }else{
            .......................
    }

我發現有每次有人send d packet size 好大.....
console.log 會print左幾行 data 出黎...(binary)...
要去到收晒data先會close connection.....

如果對方一次過send 幾百MB過黎....我咪要收晒先識得close佢個connection.....
有無方法可以一收到超過某個量就斷左佢.......
要點樣寫 ???

maxPayload

on(data, err)會等你收哂data先call, 所以入面先check length已經太遲了

call constructor時可以放埋maxPayload呢個param入去
