pythonxmlrpc服務器無法從其他計算機接收任何XMLRPC

我在 python 中使用 xmlrpc 撰寫了這個服務器，我希望能夠從任何計算機訪問這個服務器，但它會引發錯誤。另一件事是如何確保我的服務器一次可以支持多個客戶端？

from xmlrpc.server import SimpleXMLRPCServer
from xmlrpc.server import SimpleXMLRPCRequestHandler

# Restrict to a particular path.
class RequestHandler(SimpleXMLRPCRequestHandler):
    rpc_paths = ('/RPC2',)

# Create server
with SimpleXMLRPCServer(('82.155.18.86', 8000),
                        requestHandler=RequestHandler) as server:
    server.register_introspection_functions()

    # Register pow() function; this will use the value of
    # pow.__name__ as the name, which is just 'pow'.
    server.register_function(pow)

    # Register a function under a different name
    def adder_function(x, y):
        return x   y
    server.register_function(adder_function, 'add')

    # Register an instance; all the methods of the instance are
    # published as XML-RPC methods (in this case, just 'mul').
    class MyFuncs:
        def mul(self, x, y):
            return x * y

    server.register_instance(MyFuncs())

    # Run the server's main loop
    server.serve_forever()

這是我想在另一臺計算機上運行的客戶端

import xmlrpc.client

s = xmlrpc.client.ServerProxy('http://82.155.18.86:8000')
print(s.pow(2,3))  # Returns 2**3 = 8
print(s.add(2,3))  # Returns 5
print(s.mul(5,2))  # Returns 5*2 = 10

# Print list of available methods
print(s.system.listMethods())

但這就是我得到的回應

uj5u.com熱心網友回復：

看看檔案。

看來您混淆了埠。服務器埠是8000，但客戶端嘗試連接埠3000。那將不匹配。

使用with陳述句也是一種很好的做法，如檔案中所示。
