我想使用签名的 cookie 来查看存储在 S3 上的私有内容以及 CloudFront for CDN。

我不知道在 aws-sdk-js-v3 中使用哪些命令来获取签名的 cookie。根据新的 SDK 文档，它应该类似于下面的第二个代码示例，但我找不到包含我需要的命令的特定 npm 包。在 v2 中它是“getSignedCookie”，但我不知道它更新到了什么。

老派（v2）版本：

import AWS from "aws-sdk";

const CFSigner = new AWS.CloudFront.Signer(cfPublicKeyId, cfPrivateKey);
const policy = JSON.stringify({
        Statement: [
          {
            Resource: `https://${cfDomain}/images/*`,
            Condition: {
              DateLessThan: {
                "AWS:EpochTime": expireTime,
              },
            },
          },
        ],
      });

const myCookie = CFSigner.getSignedCookie({ policy });

尝试使用 v3 SDK

import {
  CloudFrontClient,
  CloudFrontClientConfig,
} from "@aws-sdk/client-cloudfront";
import { ICantFindAnAppropriateCommandToSignCookies } from "ICantFindAnAppropriateCommandToSignCookies";

async function signMyCookies() {
  const config: CloudFrontClientConfig = {
    apiVersion: "2015-12-08",
    credentials: {
      accessKeyId: process.env.SC_ADMIN_ACCESS_KEY_ID,
      secretAccessKey: process.env.SC_ADMIN_SECRET_ACCESS_KEY,
    },
    region: "us-east-01",
  };

  const cfClient = new CloudFrontClient(config);

  const cfDomain = process.env.CLOUDFRONT_DOMAIN;

  const twoDays = 2 * 24 * 60 * 60 * 1000;

  const expireTime = Math.floor((Date.now() + twoDays) / 1000);

  const params = {
    policy: JSON.stringify({
      Statement: [
        {
          Resource: `https://${cfDomain}/images/*`,
          Condition: {
            DateLessThan: {
              "AWS:EpochTime": expireTime,
            },
          },
        },
      ],
    }),
  };

  const command = new ICantFindAnAppropriateCommandToSignCookies(params);

  try {
    const data = await cfClient.send(command);
    console.log("SUCCESS!", data);
  } catch (error) {
    console.error("OH NO ERROR GETTING SIGNED COOKIE", error);
  } finally {
    console.log("PROCESS COMPLETE");
  }
}

看来他们还没有提供该功能。这是要遵循的功能请求 github 问题：https ://github.com/aws/aws-sdk-js-v3/issues/1862 。
