I would like to extract the data from MARVEL DEVELOPER by API code and analyze it (using R).
I got the following url from MARVEL website: http://gateway.marvel.com:80/v1/public/characters?apikey=f389fcb49ad574e10ca570867f4bfa43
I used httr package to collect the data:
install.packages("httr")
library(httr)
> url <- GET("http://gateway.marvel.com:80/v1/public/characters?orderBy=name&limit=100&apikey=f389fcb49ad574e10ca570867f4bfa43")
> content(url)
$code
[1] "MissingParameter"
$message
[1] "You must provide a hash."
I want to extract all this data to R. What should I do/read?
Thanks.
You have to provide ts (timestamp) and hash parameter. Hash is (according to documentation) = md5(ts+privateKey+publicKey)
You can compute md5 with:
library(digest)
hash <- digest(paste0(ts, privateKey, publicKey), algo="md5")
Server-side applications must pass two parameters in addition to the apikey parameter:
ts - a timestamp (or other long string which can change on a request-by-request basis)
hash - a md5 digest of the ts parameter, your private key and your public
key (e.g. md5(ts+privateKey+publicKey) For example, a user with a public key of "1234" and a private key of "abcd" could construct a valid call as follows:
http://gateway.marvel.com/v1/public/comics?ts=1&apikey=1234&hash=ffd275c5130566a2916217b101f26150 (the hash value is the md5 digest of 1abcd1234)
