使用适用于 JavaScript V3 的 AWS 开发工具包将图像从 node.js 上传到 s3 存储桶

  • 772

嘿，我在从 node.js 将图像上传到 s3 存储桶时遇到问题。我现在刚刚学习如何使用 AWS。安装模块时显示以下错误aws-sdk。

(node:23844) NOTE: We are formalizing our plans to enter AWS SDK for JavaScript (v2) into maintenance mode in 2023.

Please migrate your code to use AWS SDK for JavaScript (v3).
For more information, check the migration guide at https://a.co/7PzMCcy
(Use `node --trace-warnings ...` to show where the warning was created)

谁能帮我编写将图像上传到 s3 存储桶的代码吗？

我正在尝试创建 s3 构造函数并定义accessKeyId和secretAccessKey。具体来说，我正在按照本教程链接到 aws。

谁能帮助我使用 SDK v3 来满足我的要求？

    要使用适用于 JavaScript V3 的 AWS 开发工具包，请参阅此文档了解您需要的所有详细信息。

    Node.js 入门

    我昨天经历过这个并且有效。

    在此输入图像描述

    要尝试的示例代码。替换存储桶的名称。

    import { S3Client, CreateBucketCommand,PutObjectCommand } from "@aws-sdk/client-s3";
// Set the AWS Region.
const REGION = "us-east-1"; //e.g. "us-east-1"
// Create an Amazon S3 service client object.
const s3Client = new S3Client({ region: REGION });
export { s3Client };

// Set the parameters
const params = {
  Bucket: "MyBucket", // The name of the bucket. For example, 'sample-bucket-101'.
  Key: "sample_upload.txt", // The name of the object. For example, 'sample_upload.txt'.
  Body: "Hello world!", // The content of the object. For example, 'Hello world!".
};

const run = async () => {
  // Create an Amazon S3 bucket.

  try {
    const data = await s3Client.send(
        new CreateBucketCommand({ Bucket: params.Bucket })
    );
    console.log(data);
    console.log("Successfully created a bucket called ", data.Location);
    return data; // For unit tests.
  } catch (err) {
    console.log("Error", err);
  }


  // Create an object and upload it to the Amazon S3 bucket.
  try {
    const results = await s3Client.send(new PutObjectCommand(params));
    console.log(
        "Successfully created " +
        params.Key +
        " and uploaded it to " +
        params.Bucket +
        "/" +
        params.Key
    );
    return results; // For unit tests.
  } catch (err) {
    console.log("Error", err);
  }

};
run();
// snippet-end:[GettingStarted.JavaScript.NodeJS.sampleV3]
// For unit tests.
// module.exports = {run, params};

    我的信用信息位于 .aws/credentials 中，如下所述：

    https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/loading-node-credentials-shared.html

    使此代码正常运行后，尝试上传其他内容，例如图像。
