Question

I am executing a method of a SOAP web service which receives 3 string arguments with suds library.

第一个论点应当是XML,另一个是用户名和密码,这是我的半工作执行。

from suds.client import Client
url = "http://www.jonima.com.mx:3014/sefacturapac/TimbradoService?wsdl"
client = Client(url)
client.service.timbrado(XML_AS_STRING_HERE,  PRUEBA1 ,  12345678 )

When the first parameter contains an escaped character (ampersand, quotes, apostrophe, less than, bigger than) method does not work because the server interprets the text as if it were unescaped. If doesn t contain any of those chars the method works great

XML example without ampersand works http://dl.dropbox.com/u/1990697/no_amp.xml

XML example with ampersand doesn t work http://dl.dropbox.com/u/1990697/with_amp.xml

Any idea how can I pass XML with escaped chars?

It doesn t have to rely on suds but in python. I am using python 2.6 (How ever it could be with 2.7 if required)

我也利用了Django框架,不知道这是否有用。

Extra Info:

I have no access to modify SOAP server
Customer support told me my xml are correct and that they work for them, so the error is in my implementation (or somewhere in suds?)

Answer 1

I think the suds library is the culprit here. When you send your escaped xml into suds as a parameter to the client.service.timbrado method it also escapes it. However, it sees that you have escaped the ampersand already like this:

...
descripcion="EJE&amp;MPLO"
...

而没有越狱(尽管应该如此)。页: 1

This should result in xml snippet above looking like this:

...
descripcion="EJE&amp;amp;MPLO"
...

When I run your code with the doubly-escaped xml, I receive the following result:

<?xml version="1.0" ?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Body>
        <ns2:timbradoResponse xmlns:ns2="http://sefactura.com">
            <return>
                <status>401 - Fecha y hora de generación fuera de rango</status>
            </return>
        </ns2:timbradoResponse>
    </S:Body>
</S:Envelope>

相对于Xml格式而言,这在你的数据(距离生成的日期和时间)上是一个错误。

您在接任之前很容易逃脱任何XML的价值观。 http://wiki.python.org/moin/EscapingXml"rel=“nofollow”http://wiki.python.org/moin/EscapingXml

>>> from xml.sax.saxutils import escape
>>>
>>> escape("< & >")
 &lt; &amp; &gt;

过去,这为我工作,是为了把XML数据从净额上传到网页。

以XML为榜样开展工作

...
descripcion="EJE&MPLO"
...

之后

...
descripcion="EJE&amp;MPLO"
...

Answer 3

你们是否曾两度试图放弃他们?

如果这项服务中断,你应提交简短报告,并采取预防措施,以便你在固定服务时注意到这一报告,并取消你的工作。
