I am having a rest API where end point is like this:
/private/items/query
where I am taking id as query param so url is like:
http://localhost:8081/private/items/query?id=item1234
Now when the item contains % symbol its not reaching as query param in my APIs properly e.g. in case of item%21 what I am receiving is item!.
How can this problem be fixed?
The % symbol is generally used to encode special characters in query string e.g. + is encoded to %2B while sending as query string.
As mentioned [here][1]:
Because the percent ("%") character serves as the indicator for percent-encoded octets, it must be percent-encoded as "%25" for that octet to be used as data within a URI.
In your case you need to send %2521 which will be decoded to %21 at the backend as %25 is % when url-decoded. You can use this [link][2] for url-encoding purpose.
