本文介绍了Twisted网络编程的基础知识，包括安装指南、简单的RPC服务器搭建及客户端使用示例。通过实际操作展示如何利用Twisted进行高效可靠的网络编程。

twisted-doc-zh（Twisted中文文档项目）挪到 Launchpad 上去了，详情请见：

另外，有个翻译《Twisted Network Programming Essentials》(《Twisted网络编程必备》)

Twisted简单安装和rpc简单使用示例
from:http://wiki.huihoo.com/wiki/Twisted

Code:

http://twistedmatrix.com/trac/wiki/Downloads
wget http://tmrc.mit.edu/mirror/twisted/Twisted/2.5/Twisted-2.5.0.tar.bz2
bunzip2 Twisted-2.5.0.tar.bz2
tar xvf Twisted-2.5.0.tar
cd Twisted-2.5.0
cd zope.interface-3.3.0
python setup.py install
cd ..
python setup.py install
$ trial twisted // Trial is Twisted's testing framework.
>>> from twisted.web.client import getPage
>>> from twisted.internet import reactor
>>> def printContents(contents):
print "The Deferred has called printContents with the following contents:"
print contents
reactor.stop()
>>> deferred = getPage('http://www.huihoo.com/')
>>> deferred.addCallback(printContents)
<Deferred at 0xb9afd0>
>>> reactor.run()

Creating XML-RPC server
Server: touch twisted-xmlrpc.py

Code:

from twisted.web import xmlrpc, server
class Example(xmlrpc.XMLRPC):
"""An example object to be published."""
def xmlrpc_echo(self, x):
"""Return all passed args."""
return x
def xmlrpc_add(self, a, b):
"""Return sum of arguments."""
return a + b
if __name__ == '__main__':
from twisted.internet import reactor
r = Example()
reactor.listenTCP(7080, server.Site(r))
reactor.run()

python twisted-xmlrpc.py

Client: run client

Code:

>>> from twisted.web import xmlrpc, server
>>> import xmlrpclib
>>> s = xmlrpclib.Server('http://localhost:7080/')
>>> s.echo('huihoo')
'huihoo'
>>> s.add(1,2)
