suds.TypeNotFound：类型未找到：“ns4.SaveCRRequest”

Question

我遇到了这个错误。有人可能会提出这里有什么问题吗？

Traceback (most recent call last):

''' 
When moving Prism CRs to the Ready state, it becomes quite tedious when users have to modify the state from from Open to Analysis to Fix to Ready for each CR. It will be time-saving if we have just ONE command line utility program that is able to pull a list of CRs from any intermediate 
state, either Open or Analysis or Fix, and to Ready automatically. 

Command line options: 
    -h/--help show this help message and exit 
    -c/--cr (required) provide the list of CR numbers separated by space. 
    -o/--fo provide an output file whose content is a summary of the results.. 
    -p/--pl (required) provide the PL name. 
    -i/--fi (required if --cr is not specified) provide an input file which contains the list of CRs. 

How to use: 
    Example 1: 
     python .\move2ready.py --cr 320538 320899 --pl MSM0000.NA.0.0 
    Example 2: 
     python .\move2ready.py --fi ./cr.txt --fo ./out.txt --pl MSM0000.NA.0.0 
     Note: A typical cr.txt can be: 
       CR320538 
       CR320899 
       CR321167 
       CR322928

Answer 1

这似乎是这条线有问题，

request = self.soapclient.factory.create('ns4:SaveCRRequest') 

我的猜测是，ns4:SaveCRRequest对象不上

存在

http://prism:8000/ChangeRequestWebService.svc?wsdl
