This issue may be related to ZLib/GZip. Not sure. The workaround is to ask RestClient to send "Accept-Encoding: identity" header instead of its default "Accept-Encoding: gzip, deflate"
from mailjet-gem.
I traced this issue into RestClient::Request#decode. I dumped the "body" param to a base64 string and I used it to check whether the problem is in RestClient, Ruby, ZLib or MailJet v3 API.
To dump the "body" buffer I used RubyMine debugger, used the "Evaluate Expression" function and I evaluated Base64.strict_encode64(body)
The resulting string is : H4sIAAAAAAAAA6pWUHItKsov8sxLy1dSsFJQUtKBivimFhcnpqeCBf2TslKTSxTy8ksU0vJL81JAioJLEktKi53zU8BKTAxMFGoBAAA=
Then I wrote this very simple program :
require 'base64'
require 'zlib'
require 'stringio'
puts "RUBY_VERSION: #{RUBY_VERSION}"
puts "ZLib version: #{Zlib.zlib_version}"
DATA = "H4sIAAAAAAAAA6pWUHItKsov8sxLy1dSsFJQUtKBivimFhcnpqeCBf2TslKTSxTy8ksU0vJL81JAioJLEktKi53zU8BKTAxMFGoBAAA="
puts "\nBase64 string\n#{DATA}\n"
buffer = Base64.strict_decode64(DATA)
puts "\nRaw buffer\n#{buffer}\n\n"
gz = Zlib::GzipReader.new(StringIO.new(buffer))
begin
puts "\nZlib::GzipReader.new(StringIO.new(buffer)).read"
puts gz.read
rescue Exception => e
puts e
end
puts "\nZlib::GzipReader.new(StringIO.new(buffer)).read(77)"
puts gz.read(77)
puts "\nUsing Unix tools (base64 + gunzip)"
puts `echo #{DATA} | base64 --decode | gunzip -c - 2>&1`
Which outputs :
RUBY_VERSION: 2.1.2
ZLib version: 1.2.8
Base64 string

Zlib::GzipReader.new(StringIO.new(buffer)).read
unexpected end of file
Zlib::GzipReader.new(StringIO.new(buffer)).read(77)
{ "ErrorInfo" : "", "ErrorMessage" : "Object not found", "StatusCode" : 404 }
Using Unix tools (base64 + gunzip)
{ "ErrorInfo" : "", "ErrorMessage" : "Object not found", "StatusCode" : 404 }
gzip: stdin: unexpected end of file
So I suspect the MailJet server to return invalid GZip encoded data but at the same time, the same request run with curl works as expected :
curl -s -X GET --user "$MJ_APIKEY_PUBLIC:$MJ_APIKEY_PRIVATE" https://api.mailjet.com/v3/REST/contactslist/42
{ "ErrorInfo" : "", "ErrorMessage" : "Object not found", "StatusCode" : 404 }
But the same request with wget never output anything (nor print any error message) 👍
wget -d --http-user $MJ_APIKEY_PUBLIC --http-password=$MJ_APIKEY_PRIVATE -O result.json --header "Accept: application/json" --header "Accept-Encoding: gzip" https://api.mailjet.com/v3/REST/contactslist/42
The result.json file remains empty.
from mailjet-gem.
I made another change to the Mailjet::Resource code to force deflate encoding instead of gzip and it works like a charm ! (I'll push these changes to my fork for those interrested)
from mailjet-gem.
Fixed!
