----------------------------------
Summary: Add StringEscapeUtils function to Nifi Expression Language
Key: NIFI-2460
URL: https://issues.apache.org/jira/browse/NIFI-2460
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Reporter: Devin Fisher
When using Nifi Expression Language to build up a transport format (like JSON
or XML) there is no go way to make sure that it has been properly escaped.
Example Use Case:
When using PutHTTP to a Web Service that requires JSON input. If the incoming
data could contain String with quotes or other disallow character in JSON there
is no reliable way to Escape the inputs as you put them into a larger JSON
object.
Proposed Change:
StringEscapeUtils is part of apache commons-lang which is already a dependency
for nifi base POM. The functions in StringEscapeUtils can easily be mapped into
functions in nifi expression language.
Work Done:
I have the work done on a fork and am ready to submit a PR. That PR should get
good review since it is my first contribution (outside of a fixed typo)
