Python socket used to transfer large files

The socket recommended Maximum transmission unit is 8,192 characters, but if more than 8192 will cause problems, we can use the following methods to deal with

Client code

Import Subprocessimport Socketip_bind = ("127.0.0.1", 9000) client = Socket.socket () client.connect (ip_bind) L1 = []while True:    option = input ("client:")    Client.sendall (bytes (option,encoding= "Utf-8"))    server_data_size = Client.recv    Print (server_data_size)    a = str (server_data_size,encoding= "Utf-8"). Strip ()    print (a)    L1 = A.split (":")    print (L1)    if l1[0] = = "Server_data_size":        client_size_tmp = l1[1]        print ( CLIENT_SIZE_TMP)        client_size = Int (client_size_tmp)        print (Type (client_size))    client.send (Bytes (" Ok ", encoding=" Utf-8 "))    receive_size = 0    res =" "While    receive_size < client_size:        server_data = CLIENT.RECV (+)        receive_size + = Len (server_data)        res + = str (server_data)    else:        print (RES)        print ("-------reveive down---------")

Service-side code

Import Subprocessimport Socketip_bind = ("127.0.0.1", 9000) Server = Socket.socket () server.bind (ip_bind) Server.listen ( 1) Print ("Server is Waiting ...") Conn,add = Server.accept () print ("Server is connected client") while True:    Client_data = Conn.recv (    a = subprocess). Popen (str (client_data,encoding= "Utf-8"), stdout=subprocess. PIPE)    B = A.stdout.read ()    server_data_size = "server_data_size:" + str (len (b))    Conn.sendall (bytes (server _data_size,encoding= "Utf-8"))    Client_ack = Conn.recv (Ten)    if str (client_ack,encoding= "utf-8") = = "OK":        Conn.sendall (b)
