Question

我使用一种程序通信监测中心,其代码如下:

    HOST =        # local host
    PORT = 50000
    SERVER_ADDRESS = HOST, PORT

    # set up server socket
    s = socket.socket()
    s.bind(SERVER_ADDRESS)
    s.listen(1)

    while True:
        conn, addr = s.accept()
        connFile = conn.makefile()
        name, args, kwargs = cPickle.load(connFile)
           name = cPickle.load(connFile)
        args = cPickle.load(connFile)
        kwargs = cPickle.load(connFile)   
        res = _exportedMethods[name](*args,**kwargs)
        cPickle.dump(res,connFile) ; connFile.flush()
        conn.close()

客户网站:

class RemoteFunction(object):
    def __init__(self,serverAddress,name):
        self.serverAddress = serverAddress
        self.name = name
    def __call__(self,*args,**kwargs):
        s = socket.socket()
        s.connect(self.serverAddress)
        f = s.makefile()
        cPickle.dump((self.name, args, kwargs), f)
           cPickle.dump(self.name,f)
        cPickle.dump(args,f)     
        cPickle.dump(kwargs,f)      
        f.flush()
        res = cPickle.load(f)
        s.close()
        return res

def machine_changed_signal(machine):
    HOST =   
    PORT = 50000
    SERVER_ADDRESS = HOST, PORT
    advise = RemoteFunction(SERVER_ADDRESS, changes )
    advise(machine)

我收到以下错误信息:

Traceback (most recent call last):
  File "/home/manch011/disserver/src/disserver/gui/backends/receiver.py", line 71, in run
    args = cPickle.load(connFile)
cPickle.UnpicklingError: pickle data was truncated

After my changes the new i get the following error message:

Traceback (most recent call last):
File "/home/manch011/disserver/src/disserver/gui/backends/receiver.py", line 69, in run
name, args, kwargs = cPickle.load(connFile)
EOFError

我不熟悉小盘问,因此不能说是这样,有人可以向我解释。

Thanks in advance Chis

当你把你的袖珍改成像文档的物体时(connFile = conn.makefile(),你在你的档案中可以提供所有材料。当你做<代码>cPickle.load(connFile)时,您的袖珍/档案中的所有材料都用插头装上,因此,在第二次电话中,没有任何东西可以阻塞,这在提出例外时引起了什么抱怨。

如果你想提取功能名称、动力和高射线,则在第一个<代码>cPickle.load(connFile)上不计算你的所有数据。

客户方面:

cPickle.dump((function_name, args, kwargs), client_socket_as_file)

服务器边

name, args, kwargs = cPickle.load(connFile)
