如何使用套接字编程发送UDP数据/数据包而不使用python将其转换为字节？

Question

I tried to create a UDP socket and was successful in creating one. Now when I tried to send some raw data, socket.send wants me to convert it into bytes. But this raw data is a command to change the time of my application which I am working on, so i wanted to send the data as it is. Is there a way to send this without converting it into bytes?

here's the code i used:

Socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
bufferSize = 1024
recvBuf = 4096           
new_pkt= x00\x1c\x7fb\xb5\xfd\x00PV\xb8\x08\x9f\x08\x00E\x00\x000B\xad\x00\x00\x80\x11\x00\x00\n\xe7\xa0\xc6\n\xe7\x922\xc0\xb8\x05\xdc\x00\x1cH\xf4\t\x8d\x01\x00\x01\x01\x00\x10\x00\x00\x01,\x00\x00\x00\x004\xe6\xc0
S = Socket.connect_ex(("10.231.146.50",port))    
Socket.settimeout(10)   

Res = Socket.sendall(new_pkt)

Socket.close

obtained an error to convert the packet into bytes, while trying to send it

I get no error with Python2.7 , for send or sendall, if I put double quotes around your data string

new_pkt= "x00\x1c\x7fb\xb5\xfd\x00PV\xb8\x08\x9f\x08\x00E\x00\x000B\xad\x00\x00\x80\x11\x00\x00\n\xe7\xa0\xc6\n\xe7\x922\xc0\xb8\x05\xdc\x00\x1cH\xf4\t\x8d\x01\x00\x01\x01\x00\x10\x00\x00\x01,\x00\x00\x00\x004\xe6\xc0"

Give it a try ;-)

If you use Python3.x , you need bytes. So you just prefix your string with a b :

new_pkt_for_py3 = b"x00\x1c\x7fb\xb5\xfd...."
