Convert symbol ":" to %3A

[bleyzzi]

Hi! For working with the API, I use the URN in the parameters. Here's an example of the data and URL:

params = {
    'param': 'urn:ex:abc:12345'
}

url = "https://api.example.com"

If i understand, the colon : should be converted to %3A, but when using aiohttp, I encounter an issue where this conversion doesn't happen. As a result, the final URL incorrect. Meanwhile, requests correctly converted colons.

Aiohttp:

https://api.example.com?param=urn:ex:abc:12345

requests:

https://api.example.com?param=urn%3Aex%3Aabc%3A12345

I also tried using parameters with %3A directly. But in this case, aiohttp behaves the same way as requests, and it translates %3A into %253A.

https://api.example.com?param=urn%253Aex%253Aabc%253A12345

So, how can I send the request using aiohttp with correct url?

I use 3.11.11 aiohttp version

: is safe in a query, so there's no need to quote it. It's explicitly listed at https://github.com/aio-libs/yarl/blob/110038ac28f521e0b9c7a0615fe9b44b1b5e9deb/yarl/_quoters.py#L12

If you want to force a specific encoding of your URL, then you probably just want to pass a pre-encoded URL. See the note under: https://docs.aiohttp.org/en/stable/client_quickstart.html#passing-parameters-in-urls
