Making a Request

>> require 'web_to_pdf'
=> true

# Note: the 'Controller' here is not a reference to Rails controllers
# but an internal structure, won't interfere with your Rails app and will 
# work fine in a standalone ruby app or another framework

>> wtp = WebToPdf::APIController.new

>> data = wtp.lookup("https://news.ycombinator.com/", "10", "1024", "Wikipedia")

# Writes the PDF file to the local directory
>> File.open("news-yc.pdf","w"){|f| f.write(data)}

Installation

# In your Gemfile
gem 'webtopdf', git: 'https://github.com/mbuckbee/Web-To-Pdf-Gem.git'

Live Interactive Testing

Doublecheck results, use a Live Proxy and check your API Key with the interactive documentation at:

http://docs.webtopdfexp.apiary.io/

You will need your WEBTOPDF_API_KEY from the setup screen where you've provisioned the Web to PDF add-on.

Troubleshooting

As a sanity check it is sometimes useful to bypass your app stack and check the endpoint, your API Key and parameters directly.

Test with your browser

# Modify the following to use your actual API Key
'https://webtopdf.expeditedaddons.com/?api_key=REPLACE_WITH_YOUR_WEBTOPDF_API_KEY&content=http%3A%2F%2Fwww.wikipedia.org&html_width=1024&margin=10&title=My+PDF+Title'

A successful call will return your requested data with a HTTP result code of 200 and be in JSON format. We recommend the JSON Formatter extension as a useful tool.

In Development

The Web to PDF gem relies upon the environment variable ENV['WEBTOPDF_API_KEY'] being present and correctly configured to authenticate to the service. You will need to have this variable present in your local environment for the gem to work correctly.

If you're using Heroku, please read their Guide to Heroku Local which has instructions on easily copying your config values to your development environment.

DOTENV

https://github.com/bkeepers/dotenv

If you're trying to use Web to PDF in your local development or test environment with the dotenv gem be sure that you are loading the dotenv-rails gem with the rails-now requirement.

# Example Gemfile excerpt

gem 'dotenv-rails', :require => 'dotenv/rails-now'
gem 'iptoearth'

FOREMAN

https://github.com/ddollar/foreman

If you're having issues with configuring dotenv, you might want to try foreman which will also autoload .env files in your local environment.

Test in the Rails console

Launch rails c in your development project directory and at the prompt enter ENV[WEBTOPDF_API_KEY] which, if you've configured your development environment correctly should display your API Key.
