[jira] [Commented] (HTTPCORE-739) org.apache.hc.core5.net.URIBuilder does not decode plus characters (`+`) in the query part
[ https://issues.apache.org/jira/browse/HTTPCORE-739?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17708952#comment-17708952 ]
Michael Osipov commented on HTTPCORE-739:
-----------------------------------------
Did you check with RFC 3986? I consider the referenced spec as obsolete.
> org.apache.hc.core5.net.URIBuilder does not decode plus characters (`+`) in the query part
> ------------------------------------------------------------------------------------------
>
> Key: HTTPCORE-739
> URL: https://issues.apache.org/jira/browse/HTTPCORE-739
> Project: HttpComponents HttpCore
> Issue Type: Bug
> Components: HttpCore
> Affects Versions: 5.2.1
> Reporter: Andreas Loth
> Priority: Major
>
> Currently, when decoding the query part of an URL, a plus sign is kept als plus sign in the decoded name-value-pairs.
> Expected would be that a plus sign is decoded to a space.
> https://www.w3.org/Addressing/URL/uri-spec.html
> > Within the query string, the plus sign is reserved as shorthand notation for a space. Therefore, real plus signs must be encoded.
> I'm perfectly fine with encoding space everywhere to %20 and the plus sign everywhere to %2B (this is in my experience the most unambiguous and less error prone way to handle these characters). See HTTPCORE-628
> However, during decoding the position is the plus sign has to be respected: decode it to space in the query part but leave it as plus everywhere else.
> Test case for decoding:
> {noformat}
> * URL: https://example.org/abc/plus-+_enc-space-%20_enc-plus-%2B_/def?test=plus-+_enc-space-%20_enc-plus-%2B_&plus-+_enc-space-%20_enc-plus-%2B_=test
> * path: /abc/plus-+_enc-space- _enc-plus-+_/def
> * get argument 1 name: test
> * get argument 1 value: plus- _enc-space- _enc-plus-+_
> * get argument 2 name: plus- _enc-space- _enc-plus-+_
> * get argument 2 value: test
> {noformat}
> Test case for encoding:
> {noformat}
> * path: /abc/plus-+_space- _/def
> * get argument 1 name: test
> * get argument 1 value: plus-+_space- _
> * get argument 2 name: plus-+_space- _
> * get argument 2 value: test
> * URL: https://example.org/abc/plus-%2B_space-%20_/def?test=plus-%2B_space-%20_&plus-%2B_space-%20_=test
> {noformat}
> Potential fix (untested):
> https://github.com/apache/httpcomponents-core/blob/86ccd9b58ecc39ac5496af012a5decb33203ea1e/httpcore5/src/main/java/org/apache/hc/core5/net/URIBuilder.java#L410
> Change the vaue of the `plusAsBlank` argument from `false` to `true`.
