再顶一下，跪求帮忙啊！

#! /usr/bin/python
"""
Testlink API Sample Python 2.x Client implementation

import xmlrpclib
class TestlinkAPIClient:
# substitute your server URL Here
SERVER_URL = "http://catl-svn.catlbattery.com/testlink/lib/api/xmlrpc/v1/xmlrpc.php"
def __init__(self, devKey):
self.server = xmlrpclib.Server(self.SERVER_URL)
self.devKey = devKey
def reportTCResult(self, tcid, tpid, status):
data = {"devKey":self.devKey, "tcid":tcid, "tpid":tpid, "status":status}
return self.server.tl.reportTCResult(data)
def getInfo(self):
return self.server.tl.about()
# substitute your Dev Key Here
client = TestlinkAPIClient("da2a03f86ff80d9424eeb21f55e113d6")
# get info about the server
print client.getInfo()
# Substitute for tcid and tpid that apply to your project
result = client.reportTCResult(1132, 56646, "p")
# Typically you'd want to validate the result here and probably do something more useful with it
print "reportTCResult result was: %s" %(result)

运行错误如下：

所需要打开的PHP文件如下：

<?php
require_once("xmlrpc.class.php");
$XMLRPCServer = new TestlinkXMLRPCServer();
?>

访问状态如下所示：
