hex instead of base64 in BinData() - MongoDB

问题

Is there a way to send hex of binary value instead of base64 to BinData() in mongo ?

回答1:

HexData(3,"00112233445566778899aabbccddeeff") or UUID("00112233445566778899aabbccddeeff")

both will result: BinData(3,"ABEiM0RVZneImaq7zN3u/w==")

And the other way around:

BinData(3,"ABEiM0RVZneImaq7zN3u/w==").hex()

will result: 00112233445566778899aabbccddeeff

Only Use HexData(subtype, hexstr)
