JSON body support?

[bkervaski]

Hello! Thanks for a great library!

Anyone know if there is a way to add a JSON body for use with POST request when initiating a download?

hello @bkervaski , sadly not possible for the moment, i will take note to add this in future versions, for now i can suggest a workaround

you could for the moment, override the __start function inside the library and add the write function of the request

const { DownloaderHelper } = require('node-downloader-helper');
const data = JSON.stringify({
  todo: 'Buy the milk'
});
const dl = new DownloaderHelper('my_url', __dirname, { 
method: 'POST',
body: data, /// WORKAROUND
headers: {
    'Content-Type': 'application/json',
    'Content-Length': data.length
} } );


//------------- > WORKAROUND
dl.__start = function(){
        if (!this.__isRedirected &&
            this.state !== this.__states.RESUMED) {
            this.emit('start');
            this.__setState(this.__states.STARTED);
        }

        // Start the Download
        this.__response = null;
        this.__request = this.__downloadRequest(this.__promise.resolve, this.__promise.reject);

        // Error Handling
        this.__request.on('error', this.__onError(this.__promise.resolve, this.__promise.reject));
        this.__request.on('timeout', this.__onTimeout(this.__promise.resolve, this.__promise.reject));
        this.__request.on('uncaughtException', this.__onError(this.__promise.resolve, this.__promise.reject, true));

        this.__request.write(this.__opts.body); // WORKAROUND
        this.__request.end();
}

dl.on('end', () => console.log('Download Completed'))
dl.start();

i didnt try this, so not sure it would work, but that would be how i would implemented in the library later when i have the time

@hgouveia Thank you for the example, perfect, experimenting with it now and will report back. Above and beyond.
