我正在寫一個節點服務器,我需要發送一個32位整數到一個c#客戶端(如標題)。將JavaScript中的數字轉換爲4字節的數組
我不太確定如何做到這一點,因爲位移操作員會混淆我。我認爲我的C#客戶端期望這些整數以小端格式(我不確定,我說因爲NetworkStream
IsLittleEndian屬性是真的)。
所以說我在javascript中的變量是類似
var packetToDeliverInBytes = GetByteArrayOfSomeData();
//get the integer we need to turn into 4 bytes
var sizeOfPacket = packetToDeliver.length;
//this is what I don't know how to do
var bytes = ConvertNumberTo4Bytes(sizeOfPacket)
//then somehow do an operation that combines these two byte arrays together
//(bytes and packetToDeliverInBytes in this example)
//so the resulting byte array would be (packetToLiver.length + 4) bytes in size
//then send the bytes away to the client
socket.write(myByteArray);
我如何寫ConvertNumberTo4Bytes()函數?
獎金
如何這兩個字節數組合併爲一個,這樣我可以在一個socket.write通話
