Extract PDF from JSON

See more JSON Examples

Demonstrates how to extract a PDF file contained within JSON. The file is represented as a base64 string within the JSON. Note: This example can extract any type of file, not just a PDF file. Ruby

require 'chilkat'

success = false

json = Chilkat::CkJsonObject.new()

# Load the JSON.
success = json.LoadFile("qa_data/json/JSR5U.json")
if (success != true)
    print json.lastErrorText() + "\n";
    exit
end

# The JSON we loaded contains this:

# 	{
# 	...
# 	...
# 	  "data": {
# 	    "content": "JVBERi0xLjQ..."
# 	  }
# 	...
# 	...
# 	}

sb = Chilkat::CkStringBuilder.new()
json.StringOfSb("data.content",sb)

bd = Chilkat::CkBinData.new()
bd.AppendEncodedSb(sb,"base64")

success = bd.WriteFile("qa_output/a0015.pdf")
