Otto Fowler commented on NIFI-3303:
-----------------------------------
Ok, I think I know what is going on:
We evaluate the json escapes correctly in the evaluate script
But we do appendReplacement to take the result and put it in the end buffer.
Matcher.appendReplacement still treats $ and \ as special, so it is messing
with the output.
I have a fix I'll try
> escapeJson in ReplaceText

> Issue Type: Bug
> Affects Versions: 1.1.1
> Reporter: tianzk
> Priority: Major
> Attachments: ReplaceText_Bug.xml, config.png, dataflow.png

>
> I have some problems while using excapeJson and unescapeJson in ReplaceText
> processor.
> When I give a string: He didn’t say, “Stop”! to ReplaceText as input,and
> configure ReplaceText like: attachment config.png
> The output of ReplaceText is same with the input: He didn’t say, “Stop!”
> ,nothing changed.
> As described in NiFI Documentation the output should be: He didn’t say,
> \"Stop!\”.Did I miss something?
> Also there are problems with unescapeJson.If input is: He didn’t say,
> \”Sto\\\"p!\”,the return string will be: He didn’t say, ”Sto"p!”.
> My dataflow:(GetFile just read a file with a string as content.)
> dataflow.png
> Thanks.
