HTTParty 响应：获取图像并将字节转换为 base64 图像数据 url

Question

I am trying to download an image, and then return a base64 data url.

img = HTTParty.get('https://via.placeholder.com/150')
=> "\x89PNG\r\n\x1A\n\x00\x00\x00..."

base64_img = Base64.encode64(img)
=> "iVBORw0KGgoAAAANSUhEUgAAAJYAAACWBAMAAADOL2zRAAA..."

data_url = "data:image/png;base64," + base64_img
=> "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAJYAAA..."

When I paste that image into my browser it should render. Yet it is not valid. What am I doing wrong, any insight would be greatly appreciated.

Answer 1

Use Base64.strict_encode64(img) instead of encode64(img)
