binary file to base64 in 1.9.2

Hi,

I use a web service for delivering snailmail. I prepare a zip-file containing pdf for the letter, receivers and so on, encode it in base64 and send it as base 64 in my request. It won't work in 1.9.2 (the zip gets corrupted) but works fine in 1.8.7. I guess it's something with how binary strings are handled. This is the code that works in 1.8.7:

file_data = File.open(temp_file.path,"rb") {|io| io.read} file_data_64 = Base64.encode64(file_data)

Does anyone know how to do this in 1.9.2?

Thanks jonas

require "base64"

content = File.binread("filename") encoded = Base64.encode64(content)

There you go.

That worked well in 1.8.7, but not in 1.9.2.

The next thing I do is: response = client.request :sendWithAddressing, :body => { :in0 => file_data_64, :in1 => 'ebrevwebb', :in2 => 'jebkb', :in3 => 'ebrevwebb' }

With exactly the same ruby code the encoded file in the request starts the same but then there are diffrences. The length of the encoded file in the request is 4803 chars in 1.8.7 and 4864 chars in 1.9.2. The receiving end does not accept the request from 1.9.2 saying it's an illegal zip.

Dunno what are you doing, but works fine for me:

C:\Users\Luis>ruby -v ruby 1.9.2p290 (2011-07-09) [i386-mingw32]

C:\Users\Luis>irb irb(main):001:0> require "base64" => true irb(main):002:0> content = File.binread(".TransferManager.db"); nil => nil irb(main):003:0> content.length => 15388 irb(main):004:0> encoded = Base64.encode64(content); nil => nil irb(main):005:0> encoded.length => 20862

The 'nil' at the end is to avoid the entire binary file output in this example.

PS: there is no "File.binread" in Ruby 1.8.7, so dunno how that worked.

Well, the binread works fine for me. I tried to create a file from the encoded data and that looks fine, so the problem is something else.

I wonder if # encoding: utf-8 first in the file can mess things up.
