Subject [jira] [Commented] (HTTPCLIENT-1195) URIBuilder-created query strings are double-escaped
Date Wed, 01 Aug 2012 06:20:35 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13426347#comment-13426347

------------------------------------------

Oleg,

You were correct.  I was using the Amazon (AWS) SDK 1.3.11 which was aldo using httpclient
4.2.1 beta 1.  Newer versions of the AWS SDK don't  have the issue.  Your code is solid. 
Sorry about the false alarm.

> 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.
