python read a specific json

python json

I'm trying to read this json. I need values: PoolID, PoolSystemCapacityGb2,NumPagesUsedPool, and others..

But i can only read values for the 'PooID':1, not for the PooID':90

How can i parse this kind of json?

[{'$id': '1', '$type': 'Portal.Data.model.modelXPool, Portal.Data', 'SysId': 1234, 'PoolID': 1, 'PoolKindID': 1, 'PoolRaidLevelMixableID': 1, 'PoolEmulationTypeID': 1, 'PoolSystemCapacityGb2': 637870.75, 'PoolReservedCapacityGb2': 155320.92, 'WarningThreshold': 70, 'SystemThreshold': 80, 'DepletionThreshold': 80, 'ThresholdModeID': 2, 'StatusValue': 1005, 'StatusID': 1, 'StatusDetail': 'Utilization between 0% and Threshold', 'NumOfPoolVolumes': 12, 'MaxPagesOfCapacity': 124, 'NumPagesUsedPool': 1234, 'NumPagesForDpVol': 1234, 'CapacityPerPageKb2': 43008, 'MaxSubscription': 65535, 'DriveInterfaceID': 1, 'DriveSpeed': '', 'DriveInternalExternalID': 1, 'PoolRaidLevelID': 4, 'NumOfTiers': 1, 'PoolDriveInterface': {'$id': '2', '$type': 'Portal.Data.model.modelPoolDriveInterface, Portal.Data', 'ID': 1, 'DisplayText': 'SSD', 'XPool': [{'$ref': '1'}, {'$id': '3', '$type': 'Portal.Data.model.modelXPool, Portal.Data', 'SysId': 1234, 'PoolID': 90, 'PoolKindID': 1, 'PoolRaidLevelMixableID': 1, 'PoolEmulationTypeID': 1, 'PoolSystemCapacityGb2': 36858.77, 'PoolReservedCapacityGb2': 11222.7, 'WarningThreshold': 70, 'SystemThreshold': 80, 'DepletionThreshold': 80, 'ThresholdModeID': 2, 'StatusValue': 1005, 'StatusID': 1, 'StatusDetail': 'Utilization between 0% and Threshold', 'NumOfPoolVolumes': 12, 'MaxPagesOfCapacity': 898652, 'NumPagesUsedPool': 273620, 'NumPagesForDpVol': 898588, 'CapacityPerPageKb2': 43008, 'MaxSubscription': 65535, 'DriveInterfaceID': 1, 'DriveSpeed': '', 'DriveInternalExternalID': 1, 'PoolRaidLevelID': 6, 'NumOfTiers': 1, 'PoolDriveInterface': {'$ref': '2'}, 'Internal': {'$id': '4', '$type': 'Portal.Data.model.modelInternal, Portal.Data', 'ID': 1, 'DisplayText': 'Internal', 'XPool': [{'$ref': '1'}, {'$ref': '3'}]}, 'XEmulation': {'$id': '5', '$type': 'Portal.Data.model.modelXEmulation, Portal.Data', 'ID': 1, 'DisplayText': 'Open-V', 'XPool': [{'$ref': '1'}, {'$ref': '3'}], 'XParityGroup': []}, 'PoolKind': {'$id': '6', '$type': 'Portal.Data.model.modelPoolKind, Portal.Data', 'ID': 1, 'DisplayText': 'DP', 'XPool': [{'$ref': '1'}, {'$ref': '3'}]}, 'XRaidLevel': {'$id': '7', '$type': 'Portal.Data.model.modelXRaidLevel, Portal.Data', 'ID': 6, 'DisplayText': 'Raid-5 (7D+1P)', 'XPool': [{'$ref': '3'}], 'XParityGroup': []}, 'Valid': {'$id': '8', '$type': 'Portal.Data.model.modelValid, Portal.Data', 'ID': 1, 'DisplayText': 'Valid', 'XPool': [{'$ref': '1'}, {'$ref': '3'}], 'XPool1': []}, 'Normal': {'$id': '9', '$type': 'Portal.Data.model.modelNormal, Portal.Data', 'ID': 1, 'DisplayText': 'Warning', 'XPool': [{'$ref': '1'}, {'$ref': '3'}], 'XHdpTierVolume': []}, 'Valid1': {'$id': '10', '$type': 'Portal.Data.model.modelValid, Portal.Data', 'ID': 2, 'DisplayText': 'Invalid', 'XPool': [], 'XPool1': [{'$ref': '1'}, {'$ref': '3'}]}}]}, 'Internal': {'$ref': '4'}, 'XEmulation': {'$ref': '5'}, 'PoolKind': {'$ref': '6'}, 'XRaidLevel': {'$id': '11', '$type': 'Portal.Data.model.modelXRaidLevel, Portal.Data', 'ID': 4, 'DisplayText': 'Raid-6 (14D+2P)', 'XPool': [{'$ref': '1'}], 'XParityGroup': []}, 'Valid': {'$ref': '8'}, 'Normal': {'$ref': '9'}, 'Valid1': {'$ref': '10'}}, {'$ref': '3'}]

My code:

response = request.urlopen(myurl)
json_response = response.read()
data = json.loads(json_response)
poolid = data[0]["PoolID"]
           for mypoolid in poolid:
              print("pool",mypoolid)

--> Other error occurred: 'int' object is not iterable

thanks for help.


If you need to get all objects from JSON with some specific key, you will need to traverse all elements. This way, for example:

import json
