我用Python编写了客户端和服务器代码。在代码中，客户端将路径作为用户的输入。路径可以是文件夹或文件。之后，客户端遍历该文件夹/目录并将其中的所有文件及其子文件夹中的所有文件发送到服务器，但问题是服务器只接收一个文件，尽管客户端正在将所有文件发送到服务器。 / p>
有什么问题？
客户代码：
from socket import *
import fnmatch
import os
serverIP = '10.99.26.144'
serverPort = 12000
clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.connect((serverIP, serverPort))
path = input('Input Path:')
if os.path.exists(path):
clientSocket.send(bytes(path, 'UTF-8'))
if os.path.isfile(path):
file = open(path, "rb")
data = file.read(1024)
while (data):
clientSocket.send(data)
data = file.read(1024)
file.close()
else:
for root, dirnames, filenames in os.walk(path):
for filename in fnmatch.filter(filenames, '*.*'):
print( os.path.join(root, filename).encode('utf-8') )
clientSocket.send(os.path.join(root, filename).encode('utf-8'))
file = open(root+"\\"+filename, "rb")
data = file.read(1024)
while (data):
clientSocket.send(data)
data = file.read(1024)
file.close()
clientSocket.send("".encode('utf-8'))
else:
print("Path is invalid!")
clientSocket.close()
print("connection closed")
服务器代码：
from socket import *
import os
serverPort = 12000
serverSocket = socket(AF_INET,SOCK_STREAM)
serverSocket.bind(('',serverPort))
serverSocket.listen(1)
print('The server is ready to receive')
connectionSocket, address = serverSocket.accept()
path = connectionSocket.recv(1024)
if os.path.isfile(path):
file = open(os.path.basename(path), 'wb') #Open in binary
data = connectionSocket.recv(1024)
while (data):
file.write(data)
data = connectionSocket.recv(1024)
file.close()
else:
while True:
path = connectionSocket.recv(1024)
print(path)
if path.decode('utf-8')=="":
break
fileName = os.path.basename(path).decode('utf-8')
drive, tail = os.path.splitdrive( os.path.dirname(path))
directory = os.getcwd()+tail.decode('utf-8')
if not os.path.exists(directory):
os.makedirs(directory)
file = open( directory + "\\" + fileName, 'wb') #Open in binary
data = connectionSocket.recv(1024)
while (data):
file.write(data)
data = connectionSocket.recv(1024)
file.close()
connectionSocket.close()
print("connection closed")

所以，这里的问题是你只创建了一次文件（第一个文件）。然后将所有收到的内容（也是文件路径）写入同一个文件。
else:
while True:
path = connectionSocket.recv(1024)
print(path)
if path.decode('utf-8')=="":
break
fileName = os.path.basename(path).decode('utf-8')
drive, tail = os.path.splitdrive( os.path.dirname(path) )
directory = os.getcwd()+tail.decode('utf-8')
if not os.path.exists(directory):
**os.makedirs(directory)**
在下面的while循环中，您只是将数据写入上面创建的文件
while (data):
file.write(data)
data = connectionSocket.recv(1024)
file.close()
您需要为上述while循环中的每次读取添加create new file。

您可以使用此客户端和服务器以同步模式传输文件。传输按文件进行，当客户端向服务器发送数据时，它需要服务器的一些响应，这样我就创建了一些传输文件的协议。您可能需要根据需要修改一些语句。
我只针对多个文件进行了修改，请记住这一点。
<强>客户端：
from socket import *
import fnmatch
import os
serverIP = '127.0.0.1'
serverPort = 12000
clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.connect((serverIP,serverPort))
path = raw_input('Input Path:')
if os.path.exists(path):
clientSocket.send(bytes(path))
path_resp = clientSocket.recv(1024)
if os.path.isfile(path):
file = open(path, "rb")
data = file.read(1024)
while (data):
clientSocket.send(data)
data = file.read(1024)
file.close()
else:
file_list = []
for root, dirnames, filenames in os.walk(path):
for filename in fnmatch.filter(filenames, '*.*'):
file_list.append(os.path.join(root, filename).encode('utf-8'))
print file_list
file_list = iter(file_list)
while True:
file_transfer_done = False
try:
file_name = file_list.next()
except StopIteration, e:
str(e)
break
print('Sent file name to server %s' % file_name)
clientSocket.send(file_name)
file_resp = clientSocket.recv(1024)
print('Received server response : %s' % file_resp)
file = open(file_name, "rb")
data = file.read(1024)
while True:
if data:
clientSocket.send(data)
print('Sent data to server')
data_resp = clientSocket.recv(1024)
print('Received server responce : %s' % data_resp)
data = file.read(1024)
if not data:
clientSocket.send('file_closed')
close_resp = clientSocket.recv(1024)
break
file.close()
clientSocket.send("close".encode('utf-8'))
else:
print("Path is invalid!")
clientSocket.close()
print("connection closed")
服务器
from socket import *
import os
serverPort = 12000
serverSocket = socket(AF_INET,SOCK_STREAM)
serverSocket.bind(('',serverPort))
serverSocket.listen(1)
print('The server is ready to receive')
connectionSocket, address = serverSocket.accept()
path = connectionSocket.recv(1024)
connectionSocket.send('path_received')
if os.path.isfile(path):
file = open(os.path.basename(path), 'wb' )
data = connectionSocket.recv(1024)
while (data):
file.write(data)
data = connectionSocket.recv(1024)
file.close()
else:
while True:
path = connectionSocket.recv(1024)
print('Received file from client: %s' % path)
connectionSocket.send('file_path_received')
print('Sent responce to client : %s' % ('file_path_received'))
if path.decode('utf-8')=="":
break
fileName = os.path.basename(path)
print('File name received : %s' % fileName)
drive, tail = os.path.splitdrive( os.path.dirname(path) )
directory = os.getcwd()+tail
print directory
if not os.path.exists(directory):
os.makedirs(directory)
file = open( directory +"/"+ fileName, 'wb' )
print('New file created : %s' % fileName)
data = connectionSocket.recv(1024)
while True:
file.write(data)
print('File write done')
connectionSocket.send('Processed')
data = connectionSocket.recv(1024)
if 'file_closed' in data:
connectionSocket.send('file_done')
break
file.close()
connectionSocket.close()
print("connection closed")
注意：这是我尝试的示例代码，您可以做得更好。
