【中文标题】使用 XMLRPC 将文件从客户端发送到服务器?【英文标题】:Send file from client to server using XMLRPC? 【发布时间】:2012-02-24 07:56:35 【问题描述】:我想编写 Python 代码将文件从客户端发送到服务器。服务器需要保存客户端发送的文件。但是我的代码有一些我无法修复的错误。以下是我的服务器代码:
# server.py
from SimpleXMLRPCServer import SimpleXMLRPCServer
import os
server = SimpleXMLRPCServer(('localhost', 9000))
def save_data(data):
handle = open("x123.dat", "wb")
handle.write(data)
handle.close()
server.register_function(save_data, 'save_data')
server.serve_forever()
以及客户端代码:
# client.py
import sys, xmlrpclib
proxy = xmlrpclib.Server('http://localhost:9000')
handle = open(sys.argv[1], "rb")
proxy.save_data(handle.read())
handle.close()
然后我运行我的代码,客户端返回以下错误(这是在 Windows 上):
Traceback (most recent call last):
File "client.py", line 6, in <module> proxy.save_data(handle.read())
File "c:\python27\lib\xmlrpclib.py", line 1224, in __call__
return self.__send(self.__name, args)
File "c:\python27\lib\xmlrpclib.py", line 1575, in __request
verbose=self.__verbose
File "c:\python27\lib\xmlrpclib.py", line 1264, in request
return self.single_request(host, handler, request_body, verbose)
File "c:\python27\lib\xmlrpclib.py", line 1297, in single_request
return self.parse_response(response)
File "c:\python27\lib\xmlrpclib.py", line 1473, in parse_response
return u.close()
File "c:\python27\lib\xmlrpclib.py", line 793, in close
raise Fault(**self._stack[0])
xmlrpclib.Fault: <Fault 1: "<class 'xml.parsers.expat.ExpatError'>:not well-formed (invalid token): line 7, column 1">
我有一些问题:
如何修复上述错误?
我的代码有时需要传输一些大文件。由于我的方法非常简单,我怀疑它对于移动大数据是否有效。有人可以建议一种更好的方法来移动大文件吗? (当然在 Python 上使用 XMLRPC 更好)
【问题讨论】:
【参考方案1】:服务器端:
def server_receive_file(self,arg):
with open("path/to/save/filename", "wb") as handle:
handle.write(arg.data)
return True
客户端:
with open("path/to/filename", "rb") as handle:
binary_data = xmlrpclib.Binary(handle.read())
client.server_receive_file(binary_data)
这对我有用。

【参考方案2】:您想查看 xmlrpclib Binary object。使用此类,您可以对 base64 字符串进行编码和解码。

【参考方案3】:这是你的做法:
#!/usr/bin/env python3.7
# rpc_server.py
# Fix missing module issue: ModuleNotFoundError: No module named 'SimpleXMLRPCServer'
#from SimpleXMLRPCServer import SimpleXMLRPCServer
from xmlrpc.server import SimpleXMLRPCServer
import os
# Put in your server IP here
IP='10.198.16.73'
PORT=64001
server = SimpleXMLRPCServer((IP, PORT))
def server_receive_file(arg, filename):
curDir = os.path.dirname(os.path.realpath(__file__))
output_file_path = curDir + '/' + filename
print('output_file_path -> ()'.format(output_file_path))
with open(output_file_path, "wb") as handle:
handle.write(arg.data)
print('Output file: '.format(output_file_path))
return True
server.register_function(server_receive_file, 'server_receive_file')
print('Control-c to quit')
server.serve_forever()
### rpc_client.py
#!/usr/bin/env python3.7
import os
# client.py
import sys
# The answer is that the module xmlrpc is part of python3
import xmlrpc.client
#Put your server IP here
IP='10.198.16.73'
PORT=64001
url = 'http://:'.format(IP, PORT)
###server_proxy = xmlrpclib.Server(url)
client_server_proxy = xmlrpc.client.ServerProxy(url)
curDir = os.path.dirname(os.path.realpath(__file__))
filename = sys.argv[1]
fpn = curDir + '/' + filename
print(' filename -> ()'.format(filename))
print(' fpn -> ()'.format(fpn))
if not os.path.exists(fpn):
print('Missing file -> ()'.format(fpn))
sys.exit(1)
with open(fpn, "rb") as handle:
binary_data = xmlrpc.client.Binary(handle.read())
client_server_proxy.server_receive_file(binary_data, filename)
