QR Code Rails

In this project, we'll move our QR code generating Ruby programs to the internet, so that other people can easily use them.

Target

Here is a target to work towards.

Anatomy of a URL

The full anatomy of a URL (parameters are also known as query strings):

Tasks

Implement the following four URLs:

• /text

  This URL should accept a query string of the form:

  ?content=Your text goes here
  

  The value provided under content key of the query string should be encoded in a QR code as plain text.

• /url

  This URL should accept a query string of the form:

  ?page=https://www.wikipedia.org
  

  The value provided under the page key of the query string should be encoded in a QR code as a URL (which is just plain text that begins with http or https).

• /wifi

  This URL should accept a query string of the form:

  ?ssid=Your network name&pw=secret password
  

  The values provided under the ssid and pw keys should be encoded in a QR code as a wifi network. For example:

  WIFI:T:WPA;S:Your network name;P:secret password;;
  

• /sms

  This URL should accept a query string of the form:

  ?phone=9876543210&message=Hi Alice! It's me,
  

  The values provided under the phone and message keys should be encoded in a QR code as a text message: For example:

  SMSTO:9876543210:Hi Alice! It's me, 
  

Add forms

Next, let's add forms to make it easy for normal users to assemble the above URLs & query strings.
