Note: This blog post is from 2020. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.If you're trying to run a request against CF 2016 (or perhaps 11), and the URL you're using has a path which starts with /api, you may find that the request fails to run (it may give a blank page). What gives? (It was related to the CF2016 API Manager, not CF's REST services feature.)
And what can you do about it, if you are on CF2016 or 11, and you want to use /api for your URLs? There are are two choices, depending on your needs: in brief, you can either:
- change your /api folder to a new name (which I realize may not appeal to all to some)
- or change the CF configuration, to STOP it treating /api specially for the API Manager's use. You would do this by editing two CF config files, urlworkermap.properties and web.xml (but this will break the ability of the API Manager to introspect REST services in CF2016 or CF11, though not CF2018)
TLDR; if you're bold and a risk taker, you can jump to the bottom to see my list of changes to make for that second option. As is often the case, there is risk in making changes in a cavalier fashion. There are various things to consider, and I warn of them below--but the good news is that this is a change that may take only minutes to do, once you've been careful to read about how to do it effectively.
Read on for more, including pros and cons of each choice, what to change and where, why this problem NO LONGER happens from CF2018 onward, and more.
