Hi everyone, I'm trying to build an authentication server using gleam. I'm currently trying to implement some logic to send the user a welcome email when they sign up. Here's what I've got so far

Do you need any help or just showing what you got?

The main issue is that, somehow the Content-Type of the request is being set to application/octet-stream (I confirmed by running a proxy on port 9000)

I need help, but thought it would help if I show the request body I'm sending

Probably httpc does some magic. I haven't used it, can't say for sure. I'd try with another http client or dive into the source code of httpc to find out what's going on

Funny

The issue was fixed by changing the http headers to lowercase

plucky sinew Funny

I know right?

#

how do I mark this question as answered?

clear briar Mar 20, 2024, 6:07 PM

#

http standards are intriguing.

#

or the implementations.

#

I believe standard says lowercase, but many (not all!) systems work with CamelCase or at least accept it.

umbral laurel Mar 20, 2024, 6:13 PM

#

oh wow

#

that's really interesting, does that mean that other frameworks that allow uppercase are basically doing their own thing/ not fully implementing the spec?

clear briar Mar 20, 2024, 6:19 PM

#

ah, found it. http 1, case insensitive, http 2 lower case

Stack Overflow

Are HTTP headers case-sensitive?

In a blog post I use the following PHP to set the content-type of a response:
header('content-type: application/json; charset=utf-8');

I just got a comment on that post saying that content-type ne...

Interesting, it basically means that no one abides by the one true standard and many choose to, probably, win in performance avoiding additional to_lower_case
