Parsing multipart/form-data with webutils
November 1, 2014
As part of a larger effort to clean up and rewrite the opencpu package, some of the more general utilities will be moved into a new, separate package called webutils. The first release of webutils is now on CRAN.
The package contains a simple http request body parser that supports application/x-www-form-urlencoded
, multipart/form-data
, and application/json
. The multipart parser is written in pure R but surprisingly fast. Furthermore, two demo functions are included that illustrate how to host and parse simple HTML forms (with file uploads) using either rhttpd or httpuv.
Nothing ground breaking in a time of interactive graphics and restful data science as a service, but sometimes all you need is a simple form. I had a hard time finding a decent multipart parser for R, and this one does the job quite nicely.
