Tidy Helper Methods for Many Types of Unkempt Internet Metadata and Content
The ‘httr’, ‘openssl’, and ‘HARtools’ packages provide methods to retrieve rich metadata and content from internet hosts but their return objects are quite unkempt. Methods are provided to turn these objects into tidy data frames along with other useful helper methods which augment functionality in these packages.
The following functions are implemented:
download_file: Download file from the Internet (cache-aware)download_ssl_cert: Doewnload X.509 certificatesGET: GET a URLnslookup: Lookup a hostnamePOST: POST file to a serverread_har: Read HAR objectstidy_cert: Turn an openssl downloaded SSL certificate into a tidy data frametidy_har: Tidy HAR entriestidy_response: Turn an httr response object into a tidy data framewrite_har: Write HAR objects
