idea: ability to add random string/bytes to the url for dynamic urls

[timelessnesses]

Here's my suggestion
There would be something like ${random_string/bytes(length=10)}
And you could put it inside URL like this http://redirect/add?url=${random_string(10)} so you could benchmark the add redirect URL.
This might be useful if you want to stress testing for a path that's dynamic.

Interesting!
Perhaps using https://github.com/kennytm/rand_regex would be good.

I've come up with some implementation
You can install the test version by

cargo install --git https://github.com/hatoo/oha.git --branch rand-url
oha --rand-regex-url ...

I wanna hear your opinion

[timelessnesses]

sorry for late response, i tested it with subdomain url and it errored out

root@somethingcp-10161:~# oha --rand-regex-url http://redi
rect.api.timelessnesses.me/[0-9]
Error: invalid uri character

[hatoo]

. is a special meaning in regex. So

oha --rand-regex-url http://redirect\\.api\\.timelessnesses\\.me/[0-9]

would work.

This is confusing...

i would rather wrap the regex with braces or something. kind of like
https://instance.{[0-9]}.timelessnesses.me

[hatoo]

I don't like an approach that wraps the regex with braces because parsing those braces is not trivial in extreme cases such as http://localhost/{[}{]}...

So I've chosen to just escape all .s because . is not useful when generating URLs.

[timelessnesses]

ah okay I see your reason

[obriat]

How do you escape ? (query string), I try \\? or \? without success.
You should add a debug mode to display called urls, no?

[hatoo]

I don't know about escaping either.

This is a great idea. I'll implement it.

[obriat]

I find out this escape sequence :

\\/path\\?variable=[a-z]{3,15}

Escaping the slash / should be documented.
I don't get the usefulness of --max-repeat other {x,y}, could you please provide details or examples?

[hatoo]

I merged #549

Escaping on shells depends on how you quote it.
in my Bash

cargo run -- --dump-urls 16 --rand-regex-url 'http://localhost:3000/path/\?variable=[a-z]{3,15}'

Just ok.

--max-repeat exists because how many times repeated by regex *, + is unknown and ideally a user sets it.
If you use {x, y}, --max-repeat is not effect.

Thanks !
May be you should update the doc/README and give more details and exemple about regex and quote ?
