获取位于特定S3文件夹下的对象的列表 [英] GET list of objects located under a specific S3 folder

问题描述

我正在尝试使用查询字符串获取S3存储桶中特定文件夹下的对象列表，该查询字符串以文件夹名称为参数，并使用Node JS aws-sdk列出与该特定文件夹匹配的所有对象

例如: http://localhost:3000/listobjects?foldername = xxx

请提出如何实现此功能的建议.

解决方案

您可以在aws-sdk

中调用 getObject 或 listObjectsV2 时指定前缀.

  var params = {值区:"STRING_VALUE"，/*为必填项*/前缀:"STRING_VALUE"//可以是您的文件夹名称};s3.listObjectsV2(params，function(err，data){如果(err)console.log(err，err.stack);//发生错误其他console.log(data);//成功回应}); 

顺便说一句，S3没有文件夹.它只是一个前缀.它显示了文件夹结构，使您也可以轻松浏览和查看文件.

I am trying to GET a list of objects located under a specific folder in an S3 bucket using a query-string which takes the foldername as the parameter and list all objects which match that specific folder using Node JS aws-sdk

For example: http://localhost:3000/listobjects?foldername=xxx

Please suggest how to implement this functionality.

解决方案

You can specify the prefix while calling the getObject or listObjectsV2 in aws-sdk

var params = {
  Bucket: 'STRING_VALUE', /* required */
  Prefix: 'STRING_VALUE'  // Can be your folder name
};
s3.listObjectsV2(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

By the way, S3 doesn't have folders. It is just a prefix. It shows you the folder structure to make it easy for you too navigate and see files.
