I am looking for information on decoding a base64 string. We will be receiving this back with an xml stream from a client. The base64 string is a image which we must decode and write out.
what version of U2 are you on? What O/S?
UV 10.0 and later allows you to call
ALG = "Base64"
ACTION = 2 ;* 1 = Encode, 2 = Decode
INLOC = 1 ;* 1 = Data in string, 2 = Data in file (B64DATA should hold path to file)
OUTLOC = 1 ;* 1 = Data in string, 2 = Data in file (RESULT should hold path to file)
RETURNCODE = DECODE(ALG, ACTION, B64DATA, INLOC, RESULT, OUTLOC)
IF RETURNCODE NE 0 THEN
PRINT "DECODING FAILED ":RETURNCODE
* 1 - Unsupported Algorithm
* 2 - Invalid Parameters
* 3 - Data cannot be read
* 4 - data cannot be encoded/decoded
END-----------------
You could also find a uudecode utility for your O/S. Write the data to a type 19 (DIR) file and execute the command to decode it.
-----------------
Lastly you could read RFC3548 and roll your own converter. As a hint, BYTEVAL(STR, POS) is much faster than SEQ(STR[POS,1]) under UV.
