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 Bearer Token, for which you need
user account and API key.
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)
if (interactive()) {
bitly_bearerToken("access token")
ui <- bitly_user_info(showRequestURL = TRUE)
is_bitly_user_premium_holder()
}We can also decide to update my username with a different one.
And what about the metadata about our OAUTH application?
This retrieves information about a single group that user belongs to and and then about all groups that user are associated with.
Official API documentation https://dev.bitly.com/api-reference.
The first method returns an information about myself.
bitly_bearerToken("access token")
if (interactive()) {
df <- data.frame(
pubDate = rep("2016-02-10", 4),
link = c(
"https://www.google.com",
"https://www.apple.com"
)
)
df
fin <- NULL
for (p in 1:length(df$link)) {
fin[[p]] <- bitly_create_bitlink(long_url = df$link[p])
}
}WARNING: 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).
