Hi,
While I tried to work on akka/akka-http#276
<https://github.com/akka/akka-http/issues/276>, and looked at
akka/akka#18479 <https://github.com/akka/akka/pull/18715> (PR to fix #18479
= akka/akka#18715 <https://github.com/akka/akka/pull/18715>),
I found that the following code:
Query("GROUP=10380?page=2",mode = Uri.ParsingMode.Relaxed)
throws an exception:
IllegalUriException: Illegal query: Invalid input '=', expected '+',
query-char, 'EOI', '&' or pct-encoded (line 1, column 17): GROUP=10380?page=
Wasn't akka/akka#18479 <https://github.com/akka/akka/pull/18715> (PR=
akka/akka#18715 <https://github.com/akka/akka/pull/18715>) intended to make
this a valid query string, with Uri.ParsingMode.Relaxed ?
*Additional Info*
1. I looked for a test case for this.
According to UriSpec.scala
<https://github.com/akka/akka-http/blob/b7f13dc36918c870662e5434b15a45ab94594c8e/akka-http-core/src/test/scala/akka/http/scaladsl/model/UriSpec.scala#L508L514>,
Uri("?a=b=c").query() is still invalid, although query() method has default
mode = Uri.ParsingMode.Relaxed.
2. I didn't fully understand how parsing works .... but probably it's
because CharacterClases.scala
<https://github.com/akka/akka-http/blob/b7f13dc36918c870662e5434b15a45ab94594c8e/akka-http-core/src/main/scala/akka/http/impl/model/parser/CharacterClasses.scala#L51>
defines:
val `relaxed-query-char` = VCHAR -- "%&=#"
where ('=') is made invalid?
UriParser has
private[this] val `query-char` = uriParsingMode match {
case Uri.ParsingMode.Strict ⇒ `strict-query-char`
case Uri.ParsingMode.Relaxed ⇒ `relaxed-query-char`
}
where `relaxed-query-char` is defined as above.
Thanks,
Richard
