GetPdf() type mismatch - can't unmarshal uint8 to string

[viewpnt]

Hi:
I'm trying to save a pdf or excel invoice, but I get an error after the call to getPdf() or getExcel()
- reading body error: type mismatch - can't unmarshal uint8 to string

With sess.Debug = true I can see the base64 encoded pdf but I'm unable to save the result to a file.

Is there a bug with this methods? or I'm doing something wrong?

package main

import (
	"fmt"
	"io/ioutil"
	"github.com/softlayer/softlayer-go/services"
	"github.com/softlayer/softlayer-go/session"
)

func main() {
	sess := session.New()

	sess.Debug = true

	invoiceService := services.GetBillingInvoiceService(sess)

	pdf, err := invoiceService.Id(9359539).GetPdf()

	if err != nil {
		fmt.Printf("\n Unable to retrieve invoice's Pdf:\n - %s\n", err)
		return
	}

	ioutil.WriteFile("/tmp/invoice.pdf", pdf, 0644)

}

Looks like this is a problem with the XMLRPC parser.

For now, try using the REST endpoint ( https://api.softlayer.com/rest/v3.1/ in your ~/.softlayer file)

the only issue with doing that is the response will be literally "<BASE64STRING>" so you'll have to remove the quotes around the string, and then base64 decode it to use as a pdf.

Hi:

Thank you for the workaround, now I'm able to save the pdf file after base64 decode it.
