What is custom_headers in azure python sdk methods?

Question

I'm trying to find public IP address attached to running Azure VM.

I've tried both answers as per Get IP from VM object using azure sdk in python but I'm not getting required output. Getting Public IP: None

    ...:     for interface in vm.network_profile.network_interfaces:
    ...:         name=" ".join(interface.id.split('/')[-1:])
    ...:         print (name)
    ...:         sub="".join(interface.id.split('/')[4])
    ...:         print (sub)
    ...:         thing = network_client.network_interfaces.get(sub, name).ip_configurations
    ...:         for x in thing:
    ...:             print (x.public_ip_address)
    ...:
xxx
xxx
{'additional_properties': {}, 'id': '/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.Network/publicIPAddresses/Test-ip', 'name': None, 'type': None, 'location': None, 'tags': None, 'sku': None, 'public_ip_allocation_method': None, 'public_ip_address_version': None, 'ip_configuration': None, 'dns_settings': None, 'ddos_settings': None, 'ip_tags': None, 'ip_address': None, 'public_ip_prefix': None, 'idle_timeout_in_minutes': None, 'resource_guid': None, 'provisioning_state': None, 'etag': None, 'zones': None}

whereas using network_client I'm getting output

In [6]: from azure.mgmt.network import NetworkManagementClient
In [21]: for i in network_client.public_ip_addresses.list("xxx"):
    ...:     print (i)

But here I'm getting output for all subscriptions, all resource group which basically I want to filter. Hence I think using custom_headers we may filter, but I'm not getting what would be the exact naming convention of dict I'd create for custom_headers.

• How can I get full list of available custom_headers ?
• Also can someone please share some example of listing and getting All Details of running/stopped VM?

Short version: Your question has been addressed on Github already: https://github.com/Azure/azure-sdk-for-python/issues/897

A few comments though:

• custom_headers is to define HTTP headers, which won't help for your scenario:
• By design, when you create a NetworkManagementClient you already filter by subscription, since subscription is a parameter of it.
• The parameter of public_ip_addresses.list is a resource group name, so you already filter by resource group name: See https://learn.microsoft.com/en-us/python/api/azure-mgmt-network/azure.mgmt.network.v2019_04_01.operations.publicipaddressesoperations?view=azure-python#list-resource-group-name--custom-headers-none--raw-false----operation-config-
• Your first code is fine, but you need to re-inject the public IP id into public_ip_addresses.get. NIC doesn't expand to the actual Public IP value for computational reason.
