Accessing CFHTTPPARAM Type of Body

I'm working on a project with Jason Blum and he's digging into REST web services with CFML. I'll be the first to admit that REST is something I haven't had to deal with much, so I'm glad to be learning from his research on all of this.


To make something truly RESTful, apparently you should be using a simple HTTP request's body as opposed to something like form fields when you do a post to the server. (Again, I'm a moron on all this stuff so if that's way off-base, I'm happy to learn more/be corrected.)


In CFML terms, typically you'll use CFHTTP and CFHTTPPARAM to make the call to the REST service, and use a CFHTTPPARAM type of BODY. The weird thing Jason was running into is how to get at the body content since it doesn't come through in any of the usual scopes.


Jason found a comment by Dan Switzer on a post on Mike Nimer's blog that provided the answer--you simply have to call getHttpRequestData(), which returns a struct, and the struct key CONTENT contains the body data.


Mostly blogging for my own future reference but thought others might find it helpful too.

Nice coincidence. I just learned this yesterday also. I had to create a page that will have xml posted to it. To simulate the post, I have cfhttpparam type="XML" value="#myXMLString#". The page that receives the post uses getHttpRequestData().content to get that xml file and parse it.


Some of the header info available in there can be helpful too.

Running a Django Application on Windows Server 2012 with IIS

This is a first for me since under normal circumstances we run all our Django applications on Linux with Nginx, but we're in the process of developing an application for another department and due to the requirements around this project, we'll be handing the code off to them to deploy. They don't have any experience with Linux or web servers other than IIS, so I recently took up the challenge of figuring out how to run Django applications on Windows Server 2012 with IIS.

Based on the dated or complete lack of information around this I'm assuming it's not something that's very common in the wild, so I thought I'd share what I came up with in case others need to do this.

Installing and Configuring NextPVR as a Replacement for Windows Media Center

If you follow me on Google+ you'll know I had a recent rant about Windows Media Center, which after running fine for about a year suddenly decided as of January 29 it was done downloading the program guide and by extension was therefore done recording any TV shows.

I'll spare you more ranting and simply say that none of the suggestions I got (which I appreciate!) worked, and rather than spending more time figuring out why, I decided to try something different.

NextPVR is an awesome free (as in beer, not as in freedom unfortunately ...) PVR application for Windows that with a little bit of tweaking handily replaced Windows Media Center. It can even download guide data, which is apparently something WMC no longer feels like doing.

Background I wound up going down this road in a rather circuitous way. My initial goal for the weekend project was to get Raspbmc running on one of my Raspberry Pis. The latest version of XBMC has PVR functionality so I was anxious to try that out as a …

Fixing DPI Scaling Issues in Skype for Business on Windows 10

My setup for my day job these days is a Surface Pro 4 and either an LG 34UC87M-B or a Dell P2715Q monitor, depending on where I'm working. This is a fantastic setup, but some applications have trouble dealing with the high pixel density and don't scale appropriately.
One case in point is Skype for Business. For some reason it scales correctly as I move between the Surface screen and the external monitor when I use the Dell, but on the LG monitor Skype is either massive on the external monitor, or tiny on the Surface screen.
After a big of digging around I came across a solution that worked for me, which is to change a setting in Skype's manifest file (who knew there was one?). On my machine the file is here: C:\Program Files\Microsoft Office\Office16\LYNC.EXE.MANIFEST
And the setting in question is this:
<dpiAware>True/PM</dpiAware>
Which I changed to this: <dpiAware>False/PM</dpiAware>
Note that you'll probably have to edit the file as administr…
