Can't Find Image In Aws S3 Despite Successful Upload

I am utilising ng-file-upload module

Solution 1:

If you are submitting file through form then following code might help you.

exports.uploadImageToS3Bucket = function(res, file, folder, callback) {
    var fs = require('node-fs');
    varAWS = require('aws-sdk');


    var filename = file.name; // actual filename of filevar path = file.path; //will be put into a temp directoryvar mimeType = file.type;

    var accessKeyId = config.get('s3BucketCredentials.accessKeyId');
    var secretAccessKeyId = config.get('s3BucketCredentials.secretAccessKey');
    var bucketName = config.get('s3BucketCredentials.bucket');

    var timestamp = newDate().getTime().toString();
    var str = '';
    var chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
    var size = chars.length;
    for (var i = 0; i < 5; i++) {
        var randomnumber = Math.floor(Math.random() * size);
        str = chars[randomnumber] + str;
    }
    filename = filename.replace(/\s/g, '');
    var fileNewName = str + timestamp + "-" + filename;

    fs.readFile(path, function(error, file_buffer) {
        if (error) {
            responses.imageUploadError(res,{});
        }
        AWS.config.update({accessKeyId: accessKeyId, secretAccessKey: secretAccessKeyId});
        var s3bucket = newAWS.S3();


        var params = {Bucket: bucketName, Key: folder + '/' + fileNewName, Body: file_buffer, ACL: 'public-read', ContentType: mimeType};
        s3bucket.putObject(params, function(err, data) {
            if (err) {
                console.log(err);
                responses.imageUploadError(res,{});
            } else {
                returncallback(fileNewName);
            }
        });
    });
};

But i would suggest you to use base64encoder because you can directly put a object in s3 from your node server and set the content type as the file type/extension. This Base64 approach is preferrred in most of the case as its doesnt need you to send files over http.
