從客戶端向服務器Python發送字符串消息

Question

我將這些發送行添加到客戶端和服務器的recv行后，就無法運行我的代碼。 我不知道怎么了 沒有它們，該程序將完美運行。 為了方便調試，我只粘貼了盡可能小的代碼，因為沒有這些行，代碼就很完美。

客戶端

    print ('Opening file for editting.....')
with open('C:\\Users\\dell\\Desktop\\received_file.txt', 'ab') as e:
    e.write('Ya Allah tera shukar')
e.close()
print ('Editting Done!!!')
s.send("Trial Message")
s.close()
print ("Connection closed")

Server.py

while (l): #Keep sending it until EOF id found
    conn.send(l) #Keep sending the opened file
    print(repr(l)) #repr(1) gives the string representation of contents of the file. The repr() of a string adds string quotes and backslashes:
    l = f.read(1024) #Keep reading the opened file so the contents appear on the server too
f.close()
print('Done sending the file')
print conn.recv(1024) #This is not receiving the trial message sent by client
conn.send('Thank you for connecting')
conn.close()
