🎩Tidy Helper Methods for Many Types of Unkempt Internet Metadata and Content
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 tidytidy_har: Tidy HAR entriestidy_response: Turn an httr response object into a tidy data framewrite_har: Write HAR objects
