get-cors-policy

Description

Returns the cross-origin resource sharing (CORS) configuration information that is set for the container.

To use this operation, you must have permission to perform the MediaStore:GetCorsPolicy action. By default, the container owner has this permission and can grant it to others.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-cors-policy
--container-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--container-name (string)

The name of the container that the policy is assigned to.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To view a CORS policy

The following get-cors-policy example displays the cross-origin resource sharing (CORS) policy that is assigned to the specified container.

aws mediastore get-cors-policy \
    --container-name ExampleContainer \
    --region us-west-2

Output:

{
    "CorsPolicy": [
        {
            "AllowedMethods": [
                "GET",
                "HEAD"
            ],
            "MaxAgeSeconds": 3000,
            "AllowedOrigins": [
                ""
            ],
            "AllowedHeaders": [
                ""
            ]
        }
    ]
}

Output

CorsPolicy -> (list)

The CORS policy assigned to the container.

(structure)

A rule for a CORS policy. You can add up to 100 rules to a CORS policy. If more than one rule applies, the service uses the first applicable rule listed.

AllowedOrigins -> (list)

One or more response headers that you want users to be able to access from their applications (for example, from a JavaScript XMLHttpRequest object).

Each CORS rule must have at least one AllowedOrigins element. The string value can include only one wildcard character (*), for example, http://*.example.com. Additionally, you can specify only one wildcard character to allow cross-origin access for all origins.

(string)

AllowedMethods -> (list)

Identifies an HTTP method that the origin that is specified in the rule is allowed to execute.

Each CORS rule must contain at least one AllowedMethods and one AllowedOrigins element.

(string)

AllowedHeaders -> (list)

Specifies which headers are allowed in a preflight OPTIONS request through the Access-Control-Request-Headers header. Each header name that is specified in Access-Control-Request-Headers must have a corresponding entry in the rule. Only the headers that were requested are sent back.

This element can contain only one wildcard character (*).

(string)

MaxAgeSeconds -> (integer)

The time in seconds that your browser caches the preflight response for the specified resource.

A CORS rule can have only one MaxAgeSeconds element.

ExposeHeaders -> (list)

One or more headers in the response that you want users to be able to access from their applications (for example, from a JavaScript XMLHttpRequest object).

This element is optional for each rule.
