asset-uploader

Generates signed S3 URLs to be used for file uploads and returns download urls with customizable expiration.

How to build and test:

After installing go in a standard way, these commans should work out of the box:

go get -d github.com/rchernobelskiy/asset-uploader
go build -o main github.com/rchernobelskiy/asset-uploader
go test github.com/rchernobelskiy/asset-uploader

How to use locally:

Build:

go build -o main github.com/rchernobelskiy/asset-uploader

Set credentials:

export AWS_REGION=<region>
export AWS_ACCESS_KEY_ID=<key-id>
export AWS_SECRET_ACCESS_KEY=<secret>

Run in background (pass -h to see optional flags):

./main &

Get a URL for upload and asset ID:

RESPONSE=$(curl -s -XPOST localhost:8080/asset)
UPLOAD_URL=$(echo $RESPONSE|jq -r .upload_url)
ASSET_ID=$(echo $RESPONSE|jq -r .id)

Upload some content to S3:

curl -i -XPUT -d'Hello world!' "$UPLOAD_URL"

Mark the upload complete:

curl -i -XPUT -d'{"Status":"uploaded"}' "localhost:8080/asset/$ASSET_ID"

Get a download URL:

RESPONSE=$(curl -s "localhost:8080/asset/$ASSET_ID?timeout=300")
DOWNLOAD_URL=$(echo $RESPONSE|jq -r .Download_url)

And last but not least, view the stored data from S3:

curl "$DOWNLOAD_URL"
