我用python(2.6.6)和suds实现了一个SOAP客户端。服务器需要来自客户端的证书进行身份验证。为了在python和suds中实现它,我使用了this answer from Andre Miras。这似乎也有效,因为我可以从服务器访问并获取WSDL。但我有另一个问题。在解析WSDL时,我收到xml.sax._exceptions.SAXParseException: <unknown>:1:1: not well-formed (invalid token)
错误。
要检查我是否可以真正获得WSDL我操纵了“打开”方法(请注意“打印”)
def open(self, request):
"""
Fetches the WSDL using cert.
"""
print "11 "
# self.addcredentials(request)
resp = requests.get(request.url, data=request.message,
headers=request.headers, cert=self.cert)
result = io.StringIO(resp.content.decode('utf-8'))
print str(result.getvalue())
print "<<WSDL END>>"
return result
如果我运行脚本,我会得到输出:
11

我已经削减了WSDL,因为清晰度。但我还有一个使用SOAP服务的Java客户端,可以成功读取和解析WSDL。
有人知道什么是错的吗?
答案 0 :(得分:0)
我发现我必须更换以下行。注释掉的代码是旧代码,未注释的代码是新的代码:
#import io
import StringIO
...
# result = io.StringIO(resp.content.decode('utf-8'))
result = StringIO.StringIO(resp.content)
不确定原因,但这适用于我(仅更改io.StringIO(resp.content)
无效)。
