如何使用Sails删除AWS S3中的文件？ 要上传，我使用skipper-s3

Question

I just made an upload file to AWS S3 with sails and skipper-3 and it work well. Now, how can I delete a file in AWS S3 with Sails?

When I upload the file I store in the Database the URL to AWS S3.

Answer 1

You can use AWS-SDK directly or one of the many wrappers to it available at npm .

Based on Amazon documentation you will have something like:

s3.deleteObject(params, function(err, data) {
    if (err) console.log(err, err.stack);  // error
    else     console.log();                 // deleted
});

params shall hold parameters as bucket, credentials, region, path. See the example at Amazon nodejs examples .

And, for sure you can use the AWS SDK for upload files and use other AWS services inside sails too.

Your question is answered here too.

Answer 2

skipper-s3 already contains functions to read,list or remove files. I am using below code to remove some file from the AWS S3. You can use it like this:

var skipper = require('skipper-s3')({key: KEY,secret: SECRET,bucket: BUCKET}); skipper.rm(imageName,function(){});

Check the module functions on source code

Answer 3

For single image delete at a time First, install:

npm install --save aws-sdk

Now write the below code:

var AWS = require("aws-sdk");

var s3 = new AWS.S3();

s3.config.update({
  accessKeyId: "your aws key",
  secretAccessKey: "your aws secret key"
});

s3.config.region = "your aws bucket region";


var params = {
  Bucket: "Bucket name",
  Key: "image name"
};

s3.deleteObject(params, function(err, data) {
  if (err) console.log(err, err.stack);
  // an error occurred
  console.log(data, "tttttttttttt"); // successful response
});
