Problem
When using array parameters like
'includes[]': %w[value1 value2]in requests, the OAuth1 signature calculation fails with a 401 unauthorized error because the square brackets ([]) are being double-encoded in the signature base string.The signature base string was incorrectly encoding
includes[]asincludes%255B%255Dinstead of the correctincludes%5B%5D.Solution
This PR implements proper handling of array parameters in the signature base generation:
Testing
Tested with an API that was previously failing with array parameters, which now works correctly.
Fix: #12
