Using Python and SOAPpy with iControl

Hello,

 

 

I'm definetly a newby when it comes to SOAP, and using SOAPpy. I can call simple functions in the LocalLB/Class wsdl, like get_address_class_list(). But when trying to call something like get_external_class_file_name I get an emtpy array returned. Any help would REALLY be appreciated.

 


import sys
import SOAPpy
User = 'admin'
Pwd =  sys.argv[1]
SOAPpy.Config.debug = 1
Location = 'https://admin:%s@10.10.1.1/iControl/iControlPortal.cgi' %( Pwd )
server = SOAPpy.SOAPProxy(Location, namespace = "urn:iControl:LocalLB/Class")
print server.get_external_class_file_name(
   SOAPpy.NameType('', 'class_names', 0,  {'items': ['myList']})
)

 

 

Output:

 


In build.
In dump. obj= 
In dump_instance. obj=  tag= None

Any ideas?

    We don't officially support Python as a dev language but I do know that several users out there are using it. One thing that I've heard is that SOAPpy doesn't support 2-dimensional arrays which we use in a large majority of our methods.

     

     

    As for your issue, since I don't know Python, I'm going solely by the SOAP trace. In your request, the signature for get_external_calss_file_name is the following

     

     

    String[] LocalLB::Class::get_external_class_file_name(
    in String[] class_names
);

     

     

    Your code:

     

     

    print server.get_external_class_file_name(
   SOAPpy.NameType('', 'class_names', 0,  {'items': ['myList']})
)

     

     

    resulted in this message

     

     

      xmlns:ns1="urn:iControl:LocalLB/Class" SOAP-ENC:root="1">
      items="">

     

     

    The class_names parameter needs to be a single dimentional array of type string with the requested class names passed in the array. Your python code is making the class_names parameter a single type with empty value. It should result in something like this:

     

     

      xmlns:ns1="urn:iControl:LocalLB/Class" SOAP-ENC:root="1">
      SOAP-ENC:arrayType="SOAP-ENC:Array[1]">
    class_name_goes_here

    This was just passed along to me from a co-worker. Give this a shot.

    server.get_external_class_file_name(class_names = ['name1','name2'])

    You can use the following patch against SOAPBuilder.py to allow SOAPpy to serialize arrays of arrays...

    
--- SOAPBuilder.py      2005-02-21 12:24:13.000000000 -0800
+++ /tmp/SOAPBuilder.py 2006-03-31 13:53:49.000000000 -0800
@@ -496,7 +496,10 @@
             elemsname = tag
         for i in data:
-            self.dump(i, elemsname, not same_type, ns_map)
+            if type(i) == type([]):
+                self.dump(i,'item')
+            else:
+                self.dump(i, elemsname, not same_type, ns_map)
         if typed: self.out.append('\n' % tag)

    Then you can succesfully use SOAPpy 100% of iControl (haven't found a call that didn't work yet):

    
url = '%%s://%s:%s@%s/iControl/iControlPortal.cgi' % (admin,passwd,bigip)
ProxyBuilder = lambda x: SOAPProxy(url % 'https', namespace='urn:iControl:' + x)
sysinfo = ProxyBuilder('System/SystemInfo')
ver = sysinfo.get_version()
print "version: %s" % ver
pool = ProxyBuilder('LocalLB/Pool')
try:
    pool.create(pool_names = ['test_pool'],
                lb_methods = ['LB_METHOD_ROUND_ROBIN'],
                members = [[{'address':'172.16.17.1','port':'80'}]])
except faultType, (ErrorFrom, ErrorMessage):      faultType is defined by SOAPpy
        if ErrorMessage.find("already exists") > 0:
            print "pool test_pool already exists..."
        else:
            print "unhandled exception:", ErrorMessage
            raise
