I wanted to create a software that can send video through socket programming. I can send 1 video at a time but when I want to send more than 2, it is stuck.
Below is the server code:
import socket
import os
IP = "127.0.0.1"
PORT = 4456
SIZE = 1024
FORMAT = "utf"
SERVER_FOLDER = "video_folder"
def main():
print("[STARTING] Server is starting.\n")
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind((IP, PORT))
server.listen()
print("[LISTENING] Server is waiting for clients.")
conn, addr = server.accept()
print(f"[NEW CONNECTION] {addr} connected.\n")
""" Receiving the folder_name """
folder_name = conn.recv(SIZE).decode(FORMAT)
""" Creating the folder """
folder_path = os.path.join(SERVER_FOLDER, folder_name)
if not os.path.exists(folder_path):
os.makedirs(folder_path)
conn.send(f"Folder ({folder_name}) created.".encode(FORMAT))
else:
conn.send(f"Folder ({folder_name}) already exists.".encode(FORMAT))
""" Receiving files """
while True:
msg = conn.recv(SIZE).decode(FORMAT)
""" Recv the file name """
print(f"[CLIENT] Received the filename: {msg}.")
file_path = os.path.join(folder_path, msg)
file = open(file_path, "wb")
conn.send(f"{file_path} filename received.".encode(FORMAT))
while True:
msg = conn.recv(SIZE) # it stuck here once the msg become nothing need help
if not msg:
conn.send("The data is saved.".encode(FORMAT))
break
file.write(msg)
print('.', end='', flush=True)
if not msg: break
file.close()
print("\ndone.")
def test():
while True:
x = "World"
print("morning")
while True:
print("Hello" + x)
break
if __name__ == "__main__":
main()
Below is the client code:
import socket
import os
IP = "127.0.0.1"
PORT = 4456
SIZE = 1024
FORMAT = "utf"
CLIENT_FOLDER = "C:/Users/wende/OneDrive/Desktop/client_folder"
def main():
""" Staring a TCP socket. """
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect((IP, PORT))
""" Folder path """
path = os.path.join(CLIENT_FOLDER, "files")
folder_name = path.split("/")[-1]
""" Sending the folder name """
msg = f"{folder_name}"
print(f"[CLIENT] Sending folder name: {folder_name}")
client.send(msg.encode(FORMAT))
""" Receiving the reply from the server """
msg = client.recv(SIZE).decode(FORMAT)
print(f"[SERVER] {msg}\n")
""" Sending files """
files = sorted(os.listdir(path))
for file_name in files:
""" Send the file name """
print(f"[CLIENT] Sending file name: {file_name}")
client.send(file_name.encode(FORMAT))
""" Recv the reply from the server """
msg = client.recv(SIZE).decode(FORMAT)
print(f"[SERVER] {msg}")
""" Send the data """
file = open(os.path.join(path, file_name), "rb")
file_data = file.read()
client.send(file_data)
print("Sending File...")
msg = client.recv(SIZE).decode(FORMAT)
print(f"[SERVER] {msg}")
if __name__ == "__main__":
main()
I have found out where the code is stuck, but I have no idea why it pauses there for no reason.
The problem I found is I keep loop the received at the server and once the received part is NULL then the loop will stop, but the problem I faced is once the received part is NULL, it cannot jump to the next if statement to check. I try transfer 1 video is no problem at all.
How can I solve this?
