Base64
Return a new write-only I/O stream, which converts any bytes written to it into base64-encoded ASCII bytes written to ostream
. Calling close
on the Base64EncodePipe
stream is necessary to complete the encoding (but does not close ostream
).
Examples
julia> io = IOBuffer();
julia> iob64_encode = Base64EncodePipe(io);
julia> write(iob64_encode, "Hello!")
6
julia> close(iob64_encode);
julia> str = String(take!(io))
"SGVsbG8h"
julia> String(base64decode(str))
"Hello!"
Given a write
-like function writefunc
, which takes an I/O stream as its first argument, base64encode(writefunc, args...)
calls writefunc
to write to a base64-encoded string, and returns the string. base64encode(args...)
is equivalent to base64encode(write, args...)
: it converts its arguments into bytes using the standard functions and returns the base64-encoded string.

Base64DecodePipe(istream)
Return a new read-only I/O stream, which decodes base64-encoded data read from istream
.
Examples
julia> io = IOBuffer();
julia> iob64_decode = Base64DecodePipe(io);
julia> write(io, "SGVsbG8h")
8
julia> seekstart(io);
See also .
Examples
julia> b = base64decode("SGVsbG8h")
6-element Array{UInt8,1}:
0x48
0x65
0x6c
0x6c
0x6f
0x21
julia> String(b)
"Hello!"
Returns an AbstractString
containing the representation of x
in the requested mime
type. This is similar to except that binary data is base64-encoded as an ASCII string.
The optional keyword argument context
can be set to :key=>value
pair or an IO
or object whose attributes are used for the I/O stream passed to .
