Anyone here know about Python encoding stuff?

Or encoding stuff in general?

I've got a file that I need to put in a web request. Using MIME stuff as per stackoverflow.com/a/15763629/1849664 to do this; it needs to be multipart/related (XOP, ugh)

Byte Commander

I'd say yes, but depends on the question

Undo

I've got an example of a working request from a black-box system, and a not-working request from my Python system (building a replacement)

I also have to source file

Looking at everything in hex, it's kinda confusing

Here's a snippet of hex from the successful request:

sounds like data you can not share?

I'm pretty sure requests-toolbelt has an encoder for multipart/related, let me check

you can do a blank newline at the beginning instead

Now, the fun part - the file hex matches the failing request.

which makes no darn sense to me

wait, no, that's not true

This snippet from the file:

28 56 40 31 95 58 6b 4f 9e 2d 25 55 eb be b1 43 7f

Goes to this in the failing request:

0x28, 0x56, 0x40, 0x31, 0xEF, 0xBF, 0xBD, 0x58, 0x6B, 0x4F, 0xEF, 0xBF, 0xBD, 0x2D, 0x25, 0x55, 0xEF, 0xBF, 0xBD, 0xEF, 0xBF, 0xBD, 0xEF, 0xBF, 0xBD, 0x43, 0x7F

and this in the successful request:

0x28, 0x56, 0x40, 0x31, 0x20, 0x58, 0x6B, 0x4F, 0x20, 0x2D, 0x25, 0x55, 0xEB, 0xBE, 0xB1, 0x43, 0x7F

I think

None of this makes sense

~~So it's like the failing request does everything right except for converting 0x00 to 0x20, but I don't like special-casing that and delving down into binary~~ nevermind, can't read

@Undo Not sure what the topic of discussion is since I just jumped into chat, but there's a bunch of non-ASCII characters in the failing one

Undo

almost looks like the 'successful' one is replacing non-ascii chars with spaces

>.>

Might not be as successful as I thought

It's complicated; measuring success is less trivial than one would hope

NobodyNada

@Undo Interesting -- not all of them though, there's a few towards the end

The failing request seems to add non-ASCII chars

(no idea if I'm being helpful or not, I just looked at the hex numbers and pointed out things that jumped out at me)

Undo

yeah, how the heck is this even working ever

Byte Commander

okay wtf

I have no clue

sorry

Undo

heh, no worries
