Question

我正在尝试从aws s3存储桶中获取对象，但数据响应为空。我的代码如下：

import * as AWS from 'aws-sdk';
public async getObjects() { 
    AWS.config.update({
      accessKeyId: "MY_KEY_ID",
      secretAccessKey: "MY_SECRET_KEY",
      region: "eu-central-1"
    });

    let s3 = new AWS.S3();
    const response = await s3.listObjects({Bucket: 'my-bucket'});
    console.log(response);
  }

我从调试器得到的响应：

 response:
   Response {
     request: [Circular],
     data: null,
     error: null,
     retryCount: 0,
     redirectCount: 0,
     httpResponse:
      HttpResponse {
        statusCode: undefined,
        headers: {},
        body: undefined,
        streaming: false,
        stream: null },
     maxRetries: 3,
     maxRedirects: 10 }

s3.listObjects不返回诺言，您应以其他方式调用它（https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#listObjects-property）：

import * as AWS from 'aws-sdk';
public getObjects() { 
    AWS.config.update({
      accessKeyId: "MY_KEY_ID",
      secretAccessKey: "MY_SECRET_KEY",
      region: "eu-central-1"
    });

    let s3 = new AWS.S3();
    s3.listObjects({Bucket: 'my-bucket'}, (err, data) => {
        if (err) console.log(err, err.stack);
        else console.log(data);
    });
  }

在Typescript中从AWS S3存储桶获取对象
