Summary: Content Viewer Format Links Do Not Use Proxy Settings
Key: NIFI-1711
URL: https://issues.apache.org/jira/browse/NIFI-1711
Project: Apache NiFi
Issue Type: Bug
Components: Core UI
Affects Versions: 0.6.0
Reporter: James Wing
Priority: Minor
The content viewer format options do not use proxy settings, and generate bad
links on a NiFi installation behind a proxy. Proxy settings were provided via
the HTTP headers X-ProxyScheme, X-ProxyHost, and X-ProxyPort. The content
viewer will initially display unformatted content fine, but then selecting
different options such as 'formatted' results in a 404.

The URL seems to start life in
[header.jsp|https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-web-content-viewer/src/main/webapp/WEB-INF/jsp/header.jsp]:
{code}
<span id="requestUrl" class="hidden"><%=
org.apache.nifi.util.EscapeUtils.escapeHtml(request.getRequestURL().toString())
%></span>
{code}
Which was sent to the client as follows:
{code}
<span id="requestUrl" class="hidden">https://nifi/nifi-content-viewer/</span>
{code}
On selecting 'formatted',the event handling Javascript concatenates this with
the new view options to navigate to URLs like this:
{code}
https://nifi/nifi-content-viewer/?mode=Formatted&access_token=MjZvmd5...
{code}
I believe properly generating links that respect the proxy settings on the
server would require logic similar to that of
[ApplicationResource.generateResourceUri()|https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-web-api/src/main/java/org/apache/nifi/web/api/ApplicationResource.java#L97].
It might also be possible to simply format the links on the client.
