使用带有转义字符的XML作为参数来使用WSDL URL [英] Consume WSDL url with XML with escaped chars as argument

问题描述

第一个字符串参数应该是一个XML，另外2个是用户名和密码，这是我的半工作实现。

从suds.client导入客户端
 url =http ：//www.jonima.com.mx：3014 / sefacturapac / TimbradoService？wsdl
 client = Client（url）
 client.service.timbrado（XML_AS_STRING_HERE，'PRUEBA1'，'12345678'）
  

当第一个参数包含转义字符（和号，引号，撇号，小于，大于）方法不起作用，因为服务器将文本解释为未转义。如果不包含任何这些字符，那么该方法的工作效果非常好。

没有&符号的XML示例可以使用
http://dl.dropbox.com/u/1990697/no_amp.xml

具有&符号的XML示例不起作用
http：//dl.dropbox .com / u / 1990697 / with_amp.xml

任何想法如何传递XML与转义的字符？

它不必依赖于suds而是依赖于python。
我正在使用python 2.6（如果需要，可以使用2.7）

我也使用Django框架，不知道是否可以有用的。

解决方案

我认为suds库是这里的罪魁祸首。当您将转义的xml作为参数发送到 client.service.timbrado 方法时，它也会转义它。但是，它看到你已经像以前一样逃避了&符号：

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

它不会进一步逃避它（虽然它应该）。您应该通过 xml.sax.saxutils.escape 运行转义的xml，然后将其传递给 client.service.timbrado 。

这应该会导致上面的xml片段如下所示：

  ... 
 descripcion =EJE& amp; amp; ampamp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; MPLO b 
当我使用双重转义的xml运行代码时，我收到以下结果：
 <？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 degeneraciónfuera de rango< / status> 
< / return> 
< / ns2：timbradoResponse> 
< / S：Body> 
< / S：信封> 
  
这是一个关于您的数据的错误（生成超出范围的日期和时间），而不是关于xml的格式。
 
I am executing a method of a SOAP web service which receives 3 string arguments with suds library.

The first string argument should be an XML and the other 2 an username and password, this is my semi-working implementation.
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)

I am also using Django framework, don't know if that could be useful.



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?)

解决方案
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"
...
And it does not escape it further (although it should).  You should run your escaped xml through xml.sax.saxutils.escape before passing it to client.service.timbrado.

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>
It is an error regarding your data (date and time of generation out of range), not about the format of the xml.
