Javascript从亚马逊s3存储桶下载文件? [英] Javascript to download a file from amazon s3 bucket?

问题描述

我试图从 Amazon S3 上的存储桶下载文件.我想知道我是否可以编写一个 javascript 来从存储桶中下载这样的文件.我在谷歌上搜索它，但找不到任何可以帮助我做到这一点的资源.

I was trying to download a file from a bucket on Amazon S3. I was wondering if I can write a javascript to download such a file from a bucket. I was googling it, but couldn't find any resources that can help me do that.

记住的一些步骤是:对 Amazon S3 进行身份验证，然后通过提供存储桶名称和文件(密钥)，下载或读取文件，以便我能够显示文件中的数据.

Some steps in mind are: authenticate Amazon S3, then by providing bucket name, and file(key), download or read the file so that I can be able to display the data in the file.

谢谢，

推荐答案

也许你可以使用 AWS Node.js API:

var AWS = require('aws-sdk');
AWS.config.update(
  {
    accessKeyId: ".. your key ..",
    secretAccessKey: ".. your secret key ..",
  }
);
var s3 = new AWS.S3();
s3.getObject(
  { Bucket: "my-bucket", Key: "my-picture.jpg" },
  function (error, data) {
    if (error != null) {
      alert("Failed to retrieve an object: " + error);
    } else {
      alert("Loaded " + data.ContentLength + " bytes");
      // do something with data.Body
    }
  }
);
