Method: regionNetworkFirewallPolicies.list

Lists all the network firewall policies that have been configured for the specified project in the given region.

HTTP request

GET https://compute.googleapis.com/compute/beta/projects/{project}/regions/{region}/firewallPolicies

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.
region

string

Name of the region scoping this request.

Query parameters

Parameters
maxResults

integer (uint32 format)

The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500)
pageToken

string

Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
filter

string

A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request.

If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either =, !=, >, <, <=, >= or :.

For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.

The :* comparison can be used to test whether a key has been defined. For example, to find all objects with owner label use:

labels.owner:*

You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels.

To filter on multiple expressions, provide each separate expression within parentheses. For example:

(scheduling.automaticRestart = true)
(cpuPlatform = "Intel Skylake")

By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example:

(cpuPlatform = "Intel Skylake") OR
(cpuPlatform = "Intel Broadwell") AND
(scheduling.automaticRestart = true)

If you want to use a regular expression, use the eq (equal) or ne (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples:

fieldname eq unquoted literal fieldname eq 'single quoted literal' fieldname eq "double quoted literal" (fieldname1 eq literal) (fieldname2 ne "literal")

The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field.

For example, to filter for instances that do not end with name "instance", you would use name ne .*instance.

You cannot combine constraints on multiple fields using regular expressions.
orderBy

string

Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.

You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first.

Currently, only sorting by name or creationTimestamp desc is supported.
returnPartialSuccess

boolean

Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.

For example, when partial success behavior is enabled, aggregatedList for a single zone scope either returns all resources in the zone or no resources, with an error code.

Request body

The request body must be empty.

Response body

If successful, the response body contains data with the following structure:
