Question

我使用以下代码来使用用PHP编写的soap webservice

#!/usr/local/bin/python

import logging
logging.basicConfig(levee = logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.wsdl').setLevel(logging.DEBUG)
import urllib2
from suds.client import Client
from suds.sax.element import Element


url = 'a sopa webservice url'
client = Client(url)

出现以下错误：

Traceback (most recent call last):
File "./auth.py", line 13, in <module>
   client = Client(url)
File "build/bdist.linux-x86_64/egg/suds/client.py", line 112, in __init__

xmlreader.IncrementalParser.parse(self, source)
File "/usr/local/lib/python2.7/xml/sax/xmlreader.py", line 125, in parse
self.close()
File "/usr/local/lib/python2.7/xml/sax/expatreader.py", line 220, in close
self.feed("", isFinal = 1)
File "/usr/local/lib/python2.7/xml/sax/expatreader.py", line 214, in feed
self._err_handler.fatalError(exc)
File "/usr/local/lib/python2.7/xml/sax/handler.py", line 38, in fatalError
raise exception
xml.sax._exceptions.SAXParseException: <unknown>:1:0: no element found

我是suds和sopa webservice的新手，我不知道这个错误意味着什么，有人可以给我一些建议吗

您需要此行来调试：

logging.getLogger('suds.transport').setLevel(logging.DEBUG)

示例输出：

DEBUG:suds.transport.http:received:

显然，即使维护的suds-jurko fork在使用权限不足的登录时也不会出错。

通常，这意味着服务器正在返回数据，但它不是有效的XML。这可能是服务器问题。

使用python suds来使用用php编写的soap webservice，会发生SAXParseException错误
