urlshorteneR wrapps 2 URL services Bit.ly and is.gd/v.gd. In order to begin shortening URLs and downloading usefull statistics about short links, you have to – in the case of http://bit.ly – authenticate using OAuth2.0.
For is.gd/v.gd there is no authentication needed.
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()) {
opts_knit$set(root.dir = "~/Documents/Documents2/R-package-urlshortener")
bitly_token <- readRDS("tests/bitly_local_token.rds")
# You can register a new pair of keys yourself - but you can also use mine - an option which is also by default
# bitly_token <- bitly_auth(key = "be03aead58f23bc1aee6e1d7b7a1d99d62f0ede8", secret = "f9c6a3b18968e991e35f466e90c7d883cc176073")
# bitly_token <- bitly_auth()
ui <- bitly_user_info(showRequestURL = TRUE)
is_bitly_user_premium_holder()
}We can also decide to update my username with a different one.
if (interactive()) {
bitly_update_user(name = "John Malc", showRequestURL = TRUE)
}And what about the metadata about our OAUTH application?
if (interactive()) {
bitly_app_details()
}This retrieves information about a single group that user belongs to and and then about all groups that user are associated with.
if (interactive()) {
bitly_retrieve_group(ui$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("http://wwaaw.opencasdoesione.gov.it/progetti/1misepac01_000443/",
"http://wwssw.opencasdoesione.gov.it/progetti/1misepac01_000031/"),
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).
