Simple, but thorough media checker.

Give it a URL and it will fetch it, extract all links to CSS/JS/Images, etc on the page and check that each exists. It will fail if any are not fetchable, if any take more than a specified timeout to fetch, if any of them have SSL issues, or if there are HTTP/HTTPS mixed content issues.

Usage

$ ./mediacheck -help
Usage of ./mediacheck:                                                                  
  -log-format string
    	log format: text or json (default "text")
  -log-level string
    	log level: info/warn/error (default "error")
  -timeout int
    	timeout (ms) (default 3000)
  -url string
    	URL to check
  -verify-ssl
    	verify SSL certificates (default true)

The only required flag is -url. -timeout is handy if you want to enforce faster media loading or if you want to allow slower media loading.

-log-level controls verbosity. -log-format lets you output the results as JSON for easier parsing. (uses logrus behind the scenes).

Examples

A successful check:

$ ./mediacheck -url=https://www.google.com/ -log-level=info

This check fails on a few resources:

./mediacheck -url=http://welcome.ccnmtl.columbia.edu/ -log-level=error

Docker

mediacheck is also available via docker. If you are running docker, you don't have to install anything, you can just run it directly like:

$ docker run thraxil/mediacheck -url=https://www.google.com/ -log-level=info
