Test API version to implement backward compatibility

Hi -

 

 

Use the get_version method. It is available in almost every interface.

Ah, so I suppose if I want a version independent way of doing this, I need to just pick an API endpoint that is supported in V9 and above, ie.

 

 

def f5_get_api_version(b):

 

version_string = str(b.System.SystemInfo.get_version())

 

major, minor, patch = [int(x) for x in version_string.split("_")[1][1:].split(".")]

 

return(major, minor, patch)

 

 

(Presuming that major, minor, and patch values are always numeric... probably a bad presumption..lol)

 

Another option is to use the System.SystemInfo.get_system_information() method.

This is what I ended up doing. Alternatively I could have had the WSDL locally stored and not performed the 2nd connection.

WSDLS_PRE = ['Management.Partition', 'LocalLB.Pool', 'LocalLB.NodeAddress',
             'LocalLB.PoolMember']

WSDLS_V11 = ['LocalLB.Pool', 'LocalLB.NodeAddressV2', 'LocalLB.Pool',
             'System.Session']

 Create F5 object
print "Connecting to iControl API on LTM %s..." % ltm
try:
    b = f5_build_bigip_object(ltm, user, pw, ['System.SystemInfo'],
                              soap_debug=SOAP_DEBUG)
except Exception, detail:
    print "=== Exception Details ===\n%s\n=========================" % detail
    fatals += 1
    continue   try next ltm in loop
else:
    print "Connection successfully established."

 Check API version
print "Determining iControl API version supported on LTM %s..." % ltm
try:
    major, minor, patch = f5_get_api_version(b)
except Exception, detail:
    print "=== Exception Details ===\n%s\n=========================" % detail
    fatals += 1
    continue   try next ltm in loop
else:
    print "API version is %d.%d.%d." % (major, minor, patch)
    if major >= 11:
        wsdls = WSDLS_V11
    else:
        wsdls = WSDLS_PRE

 Callback and create f5 object using version dependent wsdls
print "Reconnecting to iControl API to request v%s specific WSDLs..." % major
try:
    b = f5_build_bigip_object(ltm, user, pw, wsdls, soap_debug=SOAP_DEBUG)
except Exception, detail:
    print "=== Exception Details ===\n%s\n=========================" % detail
    fatals += 1
    continue   try next ltm in loop
else:
    print "Connection successfully established."
