Subject [jira] [Commented] (HTTPCLIENT-1195) URIBuilder-created query strings are double-escaped
Date Tue, 31 Jul 2012 16:52:35 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13425916#comment-13425916

Nathan Maves commented on HTTPCLIENT-1195:

Late to the game but I don't think this works in the 4.2.1 release.

URIBuilder builder = new URIBuilder();
.setParameter("q", query)
.setParameter("bq", "kindid:'1'")

notice the bq parameter.

The output as follows is still double encoded.

>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>          Components: HttpClient
>    Affects Versions: 4.2 Final
>         Environment: java version "1.6.0_24"
> OpenJDK Runtime Environment (IcedTea6 1.11.1) (6b24-1.11.1-4ubuntu3)
> OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
>            Reporter: Chris K. Jester-Young
>             Fix For: 4.2.1
>         Attachments: HTTPCLIENT-1195-2.patch, HTTPCLIENT-1195.patch
> When setting parameters in URIBuilder, the keys and values are double-escaped: once in
URIBuilder.build(), and again in URI.appendSchemeSpecificPart(). Example:
>     URIBuilder ub = new URIBuilder("http://www.google.com/");
>     ub.addParameter("foo=bar", "baz&qux");
>     ub.build();   // http://www.google.com/?foo%253Dbar=baz%2526qux
> In order to avoid this problem, URIBuilder.build() should use URI's one-argument constructor,
which does not try to do extra escaping.
