How to edit response body returned by VCR gem?

Question

I'm using VCR to record responses from other systems that i'm integrating with.

But, this response get a huge JSON an VCR is saving it in a binary format:

body:
  encoding: ASCII-8BIT
  string: !binary |-
    eyJsaXN0IjpbXSwiZmFjZXRzIjpbeyJuYW1lIjoiU2FsZXNDaGFubmVsTmFt
    ZSIsInR5cGUiOi...

Is there a way where I can save ONLY the response body as JSON?

I want to do this to edit the returned JSON in order to make other scenarios for my tests,

Thanks

From the google forum link that Cleyton supplied (I would leave a comment if I had the rep), the following change in spec_helper.rb works for me:

VCR.configure do |c|
  c.before_record do |i|
    i.response.body.force_encoding('UTF-8')
  end
end

Use decode_compressed_response in your configuration.

VCR.configure do |c|
  c.cassette_library_dir = 'cassettes'
  c.hook_into :webmock
  c.default_cassette_options = { :decode_compressed_response => true } 
end

I am using VCR 5.0.0 with this option, but still end up with binary code in my recordings. My options are set to `{ serialize_with: :yaml, record: :once, allow_playback_repeats: true, decode_compressed_response: true }` – Tom Rossi Jun 24 '19 at 15:34

Looking in VCR google forum, I was told to do my own serializer in order to get a pretty json return.

So, i've found this code. With some minor modifications, it solved my problem, formatting the response body to not be encoded as binary.

To be clear, the only modification I had to make was to remove the filter_sensitive_data parts, and it worked great. Thanks! – d3vkit Nov 14 '14 at 00:43
