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.

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

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

Yes, you are right, many thanks

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

How could you handle it?

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

The data is construct by the client

You, you have to escape

email

before putting it into that URL.

With Ktor you could use

email.encodeURLParameter()

No idea what client you use.

Or language.

In JS/TS it would be

encodeURIComponent(email)

Perfect, gonna try it

encodeURLParameter(true)

first param is spaceToPlus

works

👍 1

now the problems is that the

is also

%40

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