Get Container Metadata

Updated: February 5, 2014

The Get Container Metadata operation returns all user-defined metadata for the container.

The Get Container Metadata request may be constructed as follows. HTTPS is recommended. Replace myaccount with the name of your storage account:

 

Method Request URI HTTP Version

GET/HEAD

https://myaccount.blob.core.windows.net/mycontainer?restype=container&comp=metadata

HTTP/1.1

When making a request against the emulated storage service, specify the emulator hostname and Blob service port as 127.0.0.1:10000, followed by the emulated storage account name:

 

Method Request URI HTTP Version

GET/HEAD

http://127.0.0.1:10000/devstoreaccount1/mycontainer?restype=container&comp=metadata

HTTP/1.1

For more information, see Using the Azure Storage Emulator for Development and Testing.

The following additional parameters may be specified on the request URI.

 

Parameter Description

timeout

Optional. The timeout parameter is expressed in seconds. For more information, see Setting Timeouts for Blob Service Operations.

The following table describes required and optional request headers.

 

Request Header Description

Authorization

Required. Specifies the authentication scheme, account name, and signature. For more information, see Authentication for the Azure Storage Services.

Date or x-ms-date

Required. Specifies the Coordinated Universal Time (UTC) for the request. For more information, see Authentication for the Azure Storage Services.

x-ms-lease-id: <ID>

Optional, version 2012-02-12 and newer. If specified, Get Container Metadata only succeeds if the container’s lease is active and matches this ID. If there is no active lease or the ID does not match, error code 412 (Precondition Failed) is returned.

x-ms-version

Required for all authenticated requests, optional for anonymous requests. Specifies the version of the operation to use for this request. For more information, see Versioning for the Azure Storage Services.

x-ms-client-request-id

Optional. Provides a client-generated, opaque value with a 1 KB character limit that is recorded in the analytics logs when storage analytics logging is enabled. Using this header is highly recommended for correlating client-side activities with requests received by the server. For more information, see About Storage Analytics Logging and Azure Logging: Using Logs to Track Storage Requests.

The response includes an HTTP status code and a set of response headers.

A successful operation returns status code 200 (OK).

For information about status codes, see Status and Error Codes.

The response for this operation includes the following headers. The response may also include additional standard HTTP headers. All standard headers conform to the HTTP/1.1 protocol specification.

 

Syntax Description

x-ms-meta-name:value

Returns a string containing a name-value pair associated with the container as metadata.

ETag

The entity tag for the container. If the request version is 2011-08-18 or newer, the ETag value will be in quotes.

Last-Modified

Returns the date and time the container was last modified. The date format follows RFC 1123. For more information, see Representation of Date/Time Values in Headers.

Any operation that modifies the container or its properties or metadata updates the last modified time. Operations on blobs do not affect the last modified time of the container.

x-ms-request-id

This header uniquely identifies the request that was made and can be used for troubleshooting the request. For more information, see Troubleshooting API Operations.

x-ms-version

Indicates the version of the Blob service used to execute the request. This header is returned for requests made against version 2009-09-19 and above.

This header is also returned for anonymous requests without a version specified if the container was marked for public access using the 2009-09-19 version of the Blob service.

Date

A UTC date/time value generated by the service that indicates the time at which the response was initiated.
