Python SOAP库suds的问题：未理解WSDL

Question

下面的代码会抛出一个SAXParseException错误，提示“标签不匹配”：

from suds.client import Client <br>
url = 'http://www.didww.com/api/?wsdl'
client = Client(url, cache=None)      
print client

这是suds的问题，还是wsdl里面有错误呢？

Answer 1

我试着重现你遇到的问题，但对我来说一切都正常。

我使用的是suds 0.4版本。

运行

from suds.client import Client

client = Client('http://api.didww.com/api/index.php?wsdl', cache=None)

print client

得到的结果是

我猜他们之前的wsdl文件有点问题，但现在看起来一切都没问题了。

希望这能帮到你。

Answer 2

你有没有在浏览器或者XML查看器中查看过WSDL文件？这样可以帮助你判断问题是不是出在这个文件上。错误提示说明这个文件可能有些问题。

Answer 3

看起来对我来说是有效的，我使用的是suds 0.3.3版本（没有缓存选项 - 在我这个版本的suds中，None并不是一个有效的缓存选项）：

In [4]: from suds.client import Client
In [5]: url = 'https://xml.192.com/IDSearch.cfc?wsdl'
In [6]: c = Client(url)
In [7]: print c
