urlshorteneR wraps 2 URL services Bit.ly
and its 2 friends is.gd as well as v.gd. For
Bit.ly, in order to shorten URLs and downloading useful statistics about
them, you have to authenticate using OAuth2.0 protocol, for which you
need user account and API keys..
For 2 other services is.gd & v.gd,
there is no authentication needed. Just create desired short links, see
below.
Return some basic information about my user on Bit.ly. Additionally, is my account a “premium” one?
library("knitr")
library(urlshorteneR)## In order to use bitly functions, you first need to authenticate.
## For that execute 'bitly_auth()' in R console.if(interactive()) {
# You must register a new pair of keys yourself
# bitly_token <- bitly_auth(key = "xxx", secret = "xxx")
# bitly_token <- bitly_auth()
ui <- bitly_user_info(showRequestURL = TRUE)
is_bitly_user_premium_holder()
}We can also decide to update my username with a different one.
if (interactive()) {
bitly_update_user(name = "John Malc", showRequestURL = TRUE)
}And what about the metadata about our OAUTH application?
if (interactive()) {
bitly_app_details()
}This retrieves information about a single group that user belongs to and and then about all groups that user are associated with.
if (interactive()) {
bitly_retrieve_group(ui$default_group_guid)
bitly_retrieve_groups()
}Official API documentation https://dev.bitly.com/api-reference.
The first method returns an information about myself.
if (interactive()) {
bitly_user_info()
}if (interactive()) {
df <- data.frame(pubDate = rep("2016-02-10", 4),
link = c("https://www.google.com",
"https://www.apple.com"),
stringsAsFactors = FALSE)
df
fin = NULL
for (p in 1:length(df$link)) {
fin[[p]] <- bitly_create_bitlink(long_url = df$link[p])
}
}BEWARE: This will proceed only with the two real links, not with the NA, NULL or an empty strings. These, however, will stop the flow of the code (i.e. are errors).
