goimgdownloader

This project is created as an exercise to explore concept of bufferedchannel in golang.

Supported Endpoints

This program has two endpoints:

• GET API to request downloading n number of images. (This API schedules a worker and quickly returns the RequestID for tracking)

/work?n=<number_of_images>

• GET API to know the request status (This returns JSON containing fields with status such as queued, downloading, downloaded and failed)

/status?requestid=<requestid>

Building and Running

• Clone this repository on your local machine
• This program has one dependency for generating UUID (i.e used as request id). Install the following dependency

$ go get github.com/satori/go.uuid

• Once dependency is installed, use following command to build:

$ go build -o goimgdownloader .

• After build is successful, use below command to run:

By default, it runs on port 8090 with 5 workers. However, these settings are configurable.
