Hi guys, having troubles with call.parameter with "+" as a character. I have ContentNegotiation and DataConversion setted. Someone knows what can it be? Thanks.

[Marc Knaup]

What is the trouble?
+ in a URL query parameter means a space character.
If you wand to send a real + then you have to escape it.

[Arnau Miro]

Yes you are right, I get an space. I need to get a "+"

[Marc Knaup]

Then the problem is probably on the client side and the request URL is invalid.

[Arnau Miro]

Yes, you are right, many thanks

[Arnau Miro]

In this case I have an email parameter and the email has a "+"

[Arnau Miro]

How could you handle it?

[Marc Knaup]

If you put some data in a URL you have to escape the data first.
How do you construct your URL?
Do you use Ktor’s Url?

[Arnau Miro]

The data is construct by the client

[Marc Knaup]

How?

[Arnau Miro]

path/?email={email}

[Marc Knaup]

You, you have to escape email before putting it into that URL.

[Marc Knaup]

With Ktor you could use
email.encodeURLParameter()

[Marc Knaup]

No idea what client you use.

[Marc Knaup]

Or language.

[Marc Knaup]

In JS/TS it would be encodeURIComponent(email)

[Arnau Miro]

JS

[Arnau Miro]

Perfect, gonna try it

[Arnau Miro]

encodeURLParameter(true) first param is spaceToPlus

[Arnau Miro]

works

[Arnau Miro]

now the problems is that the @ is also %40

[Marc Knaup]

Yeah that’s okay

[Marc Knaup]

Correct in a URL

In general, be very aware about emails. Emails are a very weird format: emails can have spaces, quotes, etc.
