Python sendto telling me it needs an int
2
from socket import *
import packets
image = "testfile.bmp"
# open image
bufferSize = 2048
myfile = open(image, 'rb')
sequenceNumber = 0
totalBytes = 0
serverName = "127.0.0.1"
serverSendPort = 12000
serverSendPort = int(serverSendPort)
serverListenPort = 12001
clientSocket = socket(AF_INET, SOCK_DGRAM)
serverSocket = socket(AF_INET, SOCK_DGRAM)
while (1):
if (sequenceNumber == 0):
data = packets.mkepckt(myfile.read(bufferSize), 0,
packets.calculateChecksum(myfile.read(bufferSize), bufferSize))
clientSocket.sendto(bytearray(data),(serverName, serverSendPort))
sequenceNumber = 1
ACK, = serverSocket.recvfrom(bufferSize)
ACKchecksum = packets.calculateChecksum(ACK[1], bufferSize)
while (ACK[0] is not 0 or ACKchecksum is not ACK[2]):
clientSocket.sendto(data, (serverName, serverSendPort))
ACK, = serverSocket.recvfrom(bufferSize)
ACKchecksum = packets.calculateChecksum(ACK[1], bufferSize)
elif (sequenceNumber == 1):
data = packets.mkepckt(myfile.read(bufferSize), 1,
packets.calculateChecksum(myfile.read(bufferSize), bufferSize))
clientSocket.sendto(bytearray(data),(serverName, serverSendPort))
sequenceNumber = 0
ACK, = serverSocket.recvfrom(bufferSize)
ACKchecksum = packets.checksum(bufferSize, ACK[1])
while (ACK[0] is not 1 or ACKchecksum is not ACK[2]):
clientSocket.sendto(data, (serverName, serverSendPort))
ACK, = serverSocket.recvfrom(bufferSize)
ACKchecksum = packets.calculateChecksum(ACK[1], bufferSize)
myfile.close()
clientSocket.close()
serverSocket.close()
Not sure I needed to put my whole code, but better safe than sorry.
So for some reason, despite the fact that I have an int in the sendto. I have also tried all sorts of typecasting, from typecasting each individual element to typecasting the whole thing as an int, and I still get this error.

What is the EXACT error message? Your calls tosendto()are inconsistent, though. Some of them are passingdatadirectly, while others are passingbytearray(data)instead.

Nov 14 '18 at 20:59
The first error I got was that "TypeError("a bytes-like object is required, not 'tuple'")", so I changed I typecasted the first one, but I must have forgotten to typecast the rest. As for the exact error: "TypeError('an integer is required')"

I'm no Python expert (I'm not even a Python user), but your calls tosendto()look OK to me. What kind of object ismkepckt()returning exactly? Are you sure it is a byte array? Also, your calls tocalculateChecksum()when callingmkepckt()look suspiciously wrong to me. You are callingmyfile.read()twice, so you are passing different bytes tomkepckt()andcalculateChecksum(). Shouldn't you be passing the same bytes to both? Something like:data = myfile.read(bufferSize) data = packets.mkepckt(data, 0, packets.calculateChecksum(data, len(data)))
– Remy Lebeau
Nov 15 '18 at 17:35
Also, when callingcalculateChecksum()afterrecvfrom(), shouldn't you be usinglen(ACK)instead ofBufferSize? PassingBufferSizetorecvfrom()is the maximum number of bytes to read, but that is no guarantee that is the number of bytes actually read, it may be less.

Make packet is a tuple. It really just takes all those objects and adds them together into a local variable then returns it. I mostly did it this way so I can have all my "packet" functions in one file, to keep things clean. As for those other two things, I believe you are absolutely correct. I have changed them, thanks. Still getting that int error though, not sure what to do about it.

Thanks to help from @RemyLebeau, I was able to solve this problem by importing pickle and using that to dump my tuple into a variable, then sending that variable as the data. Not sure why the byte data gave off an error about an int, but there you go.
