python suds解析SOAP响应时出错

Question

我使用脚本从计费系统获取信息（省略IP）：

from suds.client import Client

from netaddr import *
import logging

logging.basicConfig(filename='provisionSV.log',format='%(asctime)s %(levelname)s  (message)s',level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.transport').setLevel(logging.DEBUG)

url = 'http://X.X.X.X:X/services/X?wsdl'
client = Client(url)
resultGet = client.service.getCustomerAllowancesRequestType_Search('myself', 100000000000000, 309999900000001)

在日志中我可以看到请求很好，我得到的响应是：

^{pr2}$

但我在应用程序中遇到一个sax解析异常：

Traceback (most recent call last):
File "/usr/local/lib/python3.4/xml/sax/expatreader.py", line 207, in feed
   self._parser.Parse(data, isFinal)
xml.parsers.expat.ExpatError: syntax error: line 1, column 0

During handling of the above exception, another exception occurred:

我得到的答案怎么了？在

Answer 1

多谢了，这个成功了，我写了一个插件，删除了MIME部分。这是一个简单的例子：

class MyPlugin(MessagePlugin):
    def received(self, context):
        answer = context.reply
        answerDecoded = answer.decode()
        xmlMessage = re.search(r'(<soapenv\:Envelope.*)\r', answerDecoded)
        replyFinal = xmlMessage.group(1)+'\n'
        replyFinalDecoded = replyFinal.encode()
        context.reply = replyFinalDecoded

到目前为止一切似乎都很好。在

非常感谢你的提示！在

好吧，HTTP响应主体不是格式良好的XML，因为它被包装在MIME/multipart结构中。据我所知，suds不支持“multipart/related”内容类型的响应。我认为在将回复传递给XML解析器之前，您必须自己反汇编它。在

我认为解决这个问题的最好方法可能是编写一个自定义的MessagePlugin并实现received(context)方法（实际的回复是上下文的一部分）。在
