These
headers()
methods have been this way since the initial port of ZTTP in 65b8d50. ThegetHeaders()
method in the PSR-7 Request and Response objects already return the headers asstring[][]
, so thismapWithKeys
usage is essentially a no-op.I didn't feel the need to add any specific tests for this, as the
header()
method is used internally inhasHeader()
, which is tested directly or indirectly 21 times inHttpClientTest
, sufficient to show that the expected header array is the same as it was before.
