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. Go

    success := false

    json := chilkat.NewJsonObject()

    // Load the JSON.
    success = json.LoadFile("qa_data/json/JSR5U.json")
    if success != true {
        fmt.Println(json.LastErrorText())
        json.DisposeJsonObject()
        return
    }

    // The JSON we loaded contains this:

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

    sb := chilkat.NewStringBuilder()
    json.StringOfSb("data.content",sb)

    bd := chilkat.NewBinData()
    bd.AppendEncodedSb(sb,"base64")

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

    json.DisposeJsonObject()
    sb.DisposeStringBuilder()
    bd.DisposeBinData()
