Kee Suds Module Cycle-dependent pits

The following is the core code of the SOA interface call

# !/usr/bin/python # Coding:utf-8  from Import Client
def soarequest (wsdl,fnname,data):     = Client (WSDL). Service    = getattr (soaservice,fnname) (data)    return Soarep

The problem arises:

I call an interface, always error, see:

After the debug breakpoint is positioned to the Suds module, the open method of the import class in the sxbasic.py file

    defopen (Self, options):"""Open and import the refrenced schema.        @param options:an Options Dictionary. @type options:l{options.        Options} @return: the referenced schema. @rtype: L{schema}"""        ifself.opened:returnself.opened=True Log.debug ('%s, importing ns= "%s", location= "%s "', Self.id, Self.ns[1], self.location) result=self.locate ()ifResult isNone:ifSelf.location isNone:log.debug ('imported schema (%s) Not-found', self.ns[1])            Else:result =self.download (Options) Log.debug ('imported:\n%s', result)returnResult

Log Print when self.location is None, or execute download
And the interface I'm testing has this problem, a relies on b,b in dependency c,c in a, cyclic dependency
Everything's going to be a problem.

All right, then change it.
To define an array variable outside of class import resultlist = []

    defopen (Self, options):Globalresultlist# declaring global variables        ifself.opened:returnself.opened=True Log.debug ('%s, importing ns= "%s", location= "%s "', Self.id, Self.ns[1], self.location) result=self.locate ()ifResult isNone:ifSelf.location isNone:log.debug ('imported schema (%s) Not-found', self.ns[1])            Else:                ifSelf.locationinchResultList:log.debug ('already in Resultlist') #list中存在, which means that the download has completedElse:result =self.download (Options) resultlist.append (self.location) #下载完成后, add a record to the list Log.debug ('imported:\n%s', result)returnResult

That should be fine, run, or report the same mistake.

Continue debugging

。

Resultlist has been found to be empty, that is, the operation to add a record after the download operation is not executed

So I reversed the order.

Direct success

   defopen (Self, options):Globalresultlist        ifself.opened:returnself.opened=True Log.debug ('%s, importing ns= "%s", location= "%s "', Self.id, Self.ns[1], self.location) result=self.locate ()ifResult isNone:ifSelf.location isNone:log.debug ('imported schema (%s) Not-found', self.ns[1])            Else:                ifSelf.locationinchResultList:log.debug ('already in Resultlist')                Else: Resultlist.append (self.location) result=self.download (Options) Log.debug ('imported:\n%s', result)returnResult
