// GetRoleRequest returns a request value for making API operation for
// AWS Identity and Access Management.
//
// Retrieves information about the specified role, including the role's path,
// GUID, ARN, and the role's trust policy that grants permission to assume the
// role. For more information about roles, see Working with Roles (https://docs.aws.amazon.com/IAM/latest/UserGuide/WorkingWithRoles.html).
//
// Policies returned by this API are URL-encoded compliant with RFC 3986 (https://tools.ietf.org/html/rfc3986).
// You can use a URL decoding method to convert the policy back to plain JSON
// text. For example, if you use Java, you can use the decode method of the
// java.net.URLDecoder utility class in the Java SDK. Other languages and SDKs
// provide similar functionality.
//
//    // Example sending a request using GetRoleRequest.
//    req := client.GetRoleRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
//    }
