The URL uses gRPC Transcoding syntax.

Path parameters

Parameters

string

Project ID for this request.
resourceId

string

Name of the BackendBucket resource to return.

Request body

The request body must be empty.

Response body

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

JSON representation 
{
  "id": string,
  "creationTimestamp": string,
  "name": string,
  "description": string,
  "selfLink": string,
  "bucketName": string,
  "enableCdn": boolean,
  "cdnPolicy": {

    "clientTtl": integer
  },
  "customResponseHeaders": [
    string
  ],
  "kind": string
}
Fields
id

string (fixed64 format)

[Output Only] Unique identifier for the resource; defined by the server.
creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.
name

string

Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
description

string

An optional textual description of the resource; provided by the client when the resource is created.
bucketName

string

Cloud Storage bucket name.
enableCdn

boolean

If true, enable Cloud CDN for this BackendBucket.
cdnPolicy

object

Cloud CDN configuration for this BackendBucket.
cdnPolicy.signedUrlKeyNames[]

string

[Output Only] Names of the keys for signing request URLs.
cdnPolicy.signedUrlCacheMaxAgeSec

string (int64 format)

Maximum number of seconds the response to a signed URL request will be considered fresh. After this time period, the response will be revalidated before being served. Defaults to 1hr (3600s). When serving responses to signed URL requests, Cloud CDN will internally behave as though all responses from this backend had a "Cache-Control: public, max-age=[TTL]" header, regardless of any existing Cache-Control header. The actual headers served in responses will not be altered.
cdnPolicy.cacheMode

enum

Specifies the cache setting for all responses from this backend. The possible values are: USE_ORIGIN_HEADERS Requires the origin to set valid caching headers to cache content. Responses without these headers will not be cached at Google's edge, and will require a full trip to the origin on every request, potentially impacting performance and increasing load on the origin server. FORCE_CACHE_ALL Cache all content, ignoring any "private", "no-store" or "no-cache" directives in Cache-Control response headers. Warning: this may result in Cloud CDN caching private, per-user (user identifiable) content. CACHE_ALL_STATIC Automatically cache static content, including common image formats, media (video and audio), and web assets (JavaScript and CSS). Requests and responses that are marked as uncacheable, as well as dynamic content (including HTML), will not be cached.
cdnPolicy.defaultTtl

integer

Specifies the default TTL for cached content served by this origin for responses that do not have an existing valid TTL (max-age or s-max-age). Setting a TTL of "0" means "always revalidate". The value of defaultTTL cannot be set to a value greater than that of maxTTL, but can be equal. When the cacheMode is set to FORCE_CACHE_ALL, the defaultTTL will overwrite the TTL set in all responses. The maximum allowed value is 31,622,400s (1 year), noting that infrequently accessed objects may be evicted from the cache before the defined TTL.
cdnPolicy.maxTtl

integer

Specifies the maximum allowed TTL for cached content served by this origin. Cache directives that attempt to set a max-age or s-maxage higher than this, or an Expires header more than maxTTL seconds in the future will be capped at the value of maxTTL, as if it were the value of an s-maxage Cache-Control directive. Headers sent to the client will not be modified. Setting a TTL of "0" means "always revalidate". The maximum allowed value is 31,622,400s (1 year), noting that infrequently accessed objects may be evicted from the cache before the defined TTL.
cdnPolicy.clientTtl

integer

Specifies a separate client (e.g. browser client) TTL, separate from the TTL for Cloud CDN's edge caches. Leaving this empty will use the same cache TTL for both Cloud CDN and the client-facing response. The maximum allowed value is 86400s (1 day).
customResponseHeaders[]

string

Headers that the HTTP/S load balancer should add to proxied responses.
kind

string

Type of the resource.
