Michael Ryan updated SOLR-6360:
-------------------------------
Description:
The httpclient code in HttpSolrServer currently sets a "Content-Charset" header
when making a POST request:
{code}post.setHeader("Content-Charset", "UTF-8");{code}
As far as I know this is not a real header and is not necessary. It seems this
was a mistake in the original implementation of this class, when converting
from httpclient v3 to httpclient v4. CommonsHttpSolrServer did this, which is
what the line of code above seems to have been on:
{code}post.getParams().setContentCharset("UTF-8");{code}
The actual way to set the charset in httpclient v4 is already being done
correctly, with these lines:
{code}parts.add(new FormBodyPart(p, new StringBody(v, StandardCharsets.UTF_8)));
post.setEntity(new UrlEncodedFormEntity(postParams,
StandardCharsets.UTF_8));{code}
So basically, the Content-Charset line can just be removed.
(I think the explicit setting of the Content-Type header also might be
unnecessary, but I haven't taken the time to investigate that.)
