Working with images & qr codes in Elixir Phoenix
I’m trying to get an QR code from the google API.
url = "https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=Hello%20world"
response = HTTPoison.get!(url)
How do I send the body of the response as json out in my Phoenix application?
Right now I’m getting the following error:
** (exit) an exception was raised:
** (Jason.EncodeError) invalid byte 0x89 in <<137, 80, 78, 71, 13, 10, 26, 10, 0, 0, 0, 13, 73, 72, 68, 82, 0, 0, 0, 150, 0, 0, 0, 150, 8, 2, 0, 0, 0, 179, 99, 230, 181, 0, 0, 0, 6, 98, 75, 71, 68, 0, 255, 0, 255, 0, 255, 160, 189, 167, ...>>
How do I solve this Issue?

As https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=Hello%20world returns a QR code as an image, you’d need to decode the QR code first.
