/**
 * <p>Retrieves the certificate signing request (CSR) for your private certificate authority (CA). The CSR is created when you call the <a href="https://docs.aws.amazon.com/privateca/latest/APIReference/API_CreateCertificateAuthority.html">CreateCertificateAuthority</a> action. Sign the CSR with your Amazon Web Services Private CA-hosted or on-premises root or subordinate CA. Then import the signed certificate back into Amazon Web Services Private CA by calling the <a href="https://docs.aws.amazon.com/privateca/latest/APIReference/API_ImportCertificateAuthorityCertificate.html">ImportCertificateAuthorityCertificate</a> action. The CSR is returned as a base64 PEM-encoded string. </p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { ACMPCAClient, GetCertificateAuthorityCsrCommand } from "@aws-sdk/client-acm-pca"; // ES Modules import
 * // const { ACMPCAClient, GetCertificateAuthorityCsrCommand } = require("@aws-sdk/client-acm-pca"); // CommonJS import
 * // import type { ACMPCAClientConfig } from "@aws-sdk/client-acm-pca";
 * const config = {}; // type is ACMPCAClientConfig
 * const client = new ACMPCAClient(config);
 * const input = { // GetCertificateAuthorityCsrRequest
 *   CertificateAuthorityArn: "STRING_VALUE", // required
 * };
 * const command = new GetCertificateAuthorityCsrCommand(input);
 * const response = await client.send(command);
 * // { // GetCertificateAuthorityCsrResponse
 * //   Csr: "STRING_VALUE",
 * // };
 *
 * ```
 *
 * @param GetCertificateAuthorityCsrCommandInput - {@link GetCertificateAuthorityCsrCommandInput}
 * @returns {@link GetCertificateAuthorityCsrCommandOutput}
 * @see {@link GetCertificateAuthorityCsrCommandInput} for command's `input` shape.
 * @see {@link GetCertificateAuthorityCsrCommandOutput} for command's `response` shape.
 * @see {@link ACMPCAClientResolvedConfig | config} for ACMPCAClient's `config` shape.
 *
 * @throws {@link InvalidArnException} (client fault)
 *  <p>The requested Amazon Resource Name (ARN) does not refer to an existing resource.</p>
 *
 * @throws {@link InvalidStateException} (client fault)
 *  <p>The state of the private CA does not allow this action to occur.</p>
