How to get result from NMSDK in json format or set content type to application/json

neha_T — Wed, 04 Jun 2025 13:02:39 GMT

i am using NMSDK script to get info of cluster,
but i want to get the output in json() format.

How can i set the Content type as "application/json"

<snip>

import sys
import pprint
import json
sys.path.append("./NetApp")
from NaServer import *

s = NaServer("Array", 1 , 32)
s.set_server_type("FILER")
s.set_transport_type("HTTPS")
s.set_port(443)
s.set_style("LOGIN")
s.set_admin_user("admin", "password@123")
api = NaElement("cluster-identity-get")

xi = NaElement("desired-attributes")
api.child_add(xi)

xi1 = NaElement("cluster-identity-info")
xi.child_add(xi1)

xi1.child_add_string("cluster-contact","<cluster-contact>")
xi1.child_add_string("cluster-location","<cluster-location>")
xi1.child_add_string("cluster-name","<cluster-name>")
xi1.child_add_string("cluster-serial-number","<cluster-serial-number>")
xi1.child_add_string("cluster-uuid","<cluster-uuid>")
xi1.child_add_string("rdb-uuid","<rdb-uuid>")

xo = s.invoke_elem(api)
print (type(xo))
if (xo.results_status() == "failed") :
print ("Error:\n")
print (xo.sprintf())
sys.exit (1)

print ("Received:\n")
data = xo.sprintf()
print (data)

NMSDK recieves data in the XML format which is similar to JSON. They have key value pair, can be nested into other elements arbitarily.

No, NMSDK only supports XML like formatting for the data getting sent and being recieved.

Did you try this?

obj = xmltodict.parse(xo.sprintf())
jd = json.dumps(obj)
a = Response(jd, content_type='application/json')

a = Response(jd, content_type='application/json')----> what us Response here??

No not working.

because xo.sprinf() return unicode type data.

and when we use below code

<snip>

obj = xmltodict.parse(xo.sprintf())

jd = json.dumps(obj)

a = Response(jd, content_type='application/json')

pprint.pprint(a.data)----> it return in dict format, but its data type is <str>

print data["cluster-uuid"] ---> so when try to access by it key it gives error

<snip>

Data i get:

'{"results": {"@status": "passed", "attributes": {"cluster-identity-info": {"cluster-contact": null, "cluster-location": "B", "cluster-name": "IA", "cluster-serial-number": "1--7868", "cluster-uuid": "----uuid----", "rdb-uuid": "---uuid---"}}}}'

<error>
print data["cluster-uuid"]
TypeError: string indices must be integers, not str

<error>

Try to add json loads.

obj = xmltodict.parse(xo.sprintf())
jd = json.dumps(obj)
jl = json.loads(jd)
a = Response(jl, content_type='application/json')

yes, now it is giving json output, but only class instance

when i try to get data also it is giving instance details only.

example:

obj = xmltodict.parse(xo.sprintf())

jd = json.dumps(obj)

jl = json.loads(jd)

a = Response(jl, content_type='application/json')

#pprint.pprint(dir(a))

pprint.pprint(a)--> <Response likely-streamed [200 OK]>

print a.get_json--> <bound method Response.get_json of <Response likely-streamed [200 OK]>>

print a.is_json---> True

print a._get_data_for_json--> <bound method Response._get_data_for_json of <Response likely-streamed [200 OK]>>

what i want is json data.

Initially you said, you want Application/JSON. May I know you need JSON or Application/JSON?

If you need only JSON, you can not convert XML to JSON but from XML to Dict. Though there is work around to convert using Application/JSON using Response which is usable in Flask.

If you just need JSON in order to access Dict key/values then xmltodict should work for you. You can use this way.

obj = xmltodict.parse(xo.sprintf())
jd = json.dumps(obj)
jl = json.loads(jd)

if xo.results_status() == "failed":
reason = xo.results_reason()
print ("Failure: %s" %reason)
else:

for h in jl["results"]["attributes-list"]["aggr-attributes"]:
if int(h["aggr-space-attributes"]["percent-used-capacity"]) > 80:
print (h["aggregate-name"], readable_size(int(h["aggr-space-attributes"]["size-total"])), readable_size(int(h["aggr-space-attributes"]["size-used"])), readable_size(int(h["aggr-space-attributes"]["size-available"])), h["aggr-space-attributes"]["percent-used-capacity"])
else:
pass
