Franz Forsthofer updated CAMEL-8905:
------------------------------------
Attachment: 0001-jsonpath-automatic-charset-detection.patch
I Improved the patch further. I have introduced the header
"CamelJsonpathJsonEncoding". Here the user can specify the charset of the JSON
document. In most of the cases it is not necessary to specify the charset in
the header. If the charset is one of the unicode charsets then the charset can
be determined automatically. Or if the message body is of type String or
GenericFile with CharSet then also no charset must be specified.

> I detected three different encoding problems in jsonpath:
> - if jsonpath is called with an input stream which has an encoding different
> from the default encoding (given by Charset.defaultCharset()) then jsonpath
> still uses the default encoding. Error location in JsonPathEngine:
> else if (json instanceof InputStream) {
> InputStream is = (InputStream) json;
> return path.read(is, Charset.defaultCharset().displayName(),
> configuration);}
>
> - if jsonpath is called with a json file whose encoding is different from
> UTF-8, then jsonpath still parses the document with UTF-8. Error location in
> JsonPathEngine:
> else if (json instanceof File) {
> File file = (File) json;
> return path.read(file, configuration);
> }
> path.read(file, configuration) uses always UTF-8
> - if jsonpath is called with an URL pointing to a JSON document whose
> encoding is different from UTF-8, then jsonPath still parses the document
> with UTF-8. Error location in JsonPathEngine:
> else if (json instanceof URL) {
> URL url = (URL) json;
> return path.read(url, configuration);
> }
> path.read(url, configuration) uses UTF-8
> My solution proposal is to determine the encoding of the JSON documents
> automatically according to the specification RFC-4627
> (https://www.ietf.org/rfc/rfc4627.txt; see chapter 3. Encoding) and then call
> the method path.read(jsonDocument,foundEncoding,configuration) with the found
> encoding. See attached patch.
> Actually I can commit the patch myself. However, I would like that somebody
> who is more familiar with jsonpath than I does review my patch.
> So please tell me if my patch can be accepted or not. I can then do the
> actual commit or I will discard the patch.
