--------------------------------
Summary: CORS Support for Avatica Requests on Phoenix Query Server
Key: PHOENIX-2661
URL: https://issues.apache.org/jira/browse/PHOENIX-2661
Project: Phoenix
Issue Type: New Feature
Affects Versions: 4.6.0, 4.7.0
Reporter: Steve T
Priority: Minor
It would be super cool if I could write Javascript in a web page to read/write
my Phoenix tables. I spend the last few days learning about CORS and browser
security. I found out that what I am trying to accomplish cannot be readily
done because the browser adds CORS headers (like
{color:blue}{{Origin:}}{color}) and methods (like {color:blue}{{method:
OPTIONS}}{color}) that are not supported by Phoenix Query Server.
I do not know if this can be added on the Phoenix side or if it has to be added
on the Avatica side, but for the time being I am trying the following to make
it work:
1. Unconventional Javascript to remove the
{color:blue}{{X-Requested-With}}{color} header in the request.
2. One line code change in Avatica's
{color:blue}{{AvaticaJsonHandler.handle()}}{color} to add an
{color:blue}{{Origin: *}}{color} header to the response.
