Description

Examples

Reads text from container:

MBS( "Text.ReadTextFromContainer"; test::test; "UTF8" )

Extract text from gzip compressed text with prefixed length:

# get some response string, gzip compressed with length before
// Set Variable [ $response ; Value: GzipDecompress::InputString ]
Set Variable [ $response ; Value: "RAAAAB+LCAAAAAAABACrZlBicGbIZ0hhSAWyrBhMGAwYDBl0gOwwhkSGHIZSqLgSEIJEg4BqSxlKkE RrGQAjtv6kRAAAAA==" ]
# convert base64 to Hex
Set Variable [ $hex ; Value: MBS( "Text.DecodeHexFromBase64"; $response ) ]
# now we can remove the first 4 bytes with length
Set Variable [ $hexNum ; Value: Left($hex; 8) ]
Set Variable [ $Rest ; Value: Middle ( $hex; 9; 100000000 ) ]
# we can decode the length value
Set Variable [ $len ; Value: MBS("Math.DecodeNumber"; "Integer"; 32; $hexNum) ]
# and read to container value from hex
Set Variable [ $Cont ; Value: MBS( "Container.DecodeFromHex"; "FILE"; $Rest; "test.gz" ) ]
# now decompress gzip
Set Variable [ $Decompressed ; Value: MBS( "Archive.GZipDecompress"; $cont; "test.txt") ]
# and read it as text. it is little endian UTF-16 here!
Set Variable [ $result ; Value: MBS( "Text.ReadTextFromContainer"; $Decompressed; "UTF-16LE") ]
# show in field
Set Field [ GzipDecompress::OutputString ; $result ]
Show Custom Dialog [ "Result" ; $result ]

Example result:
{"Code":401,"Value":"","Route":""}
