I'm very new in clojure. I don't have any experience with java & it's library functions. I wrote a function in clojure which return base64 encrypted data using java.util.Base64/getUrlEncoder. My code look like:
user> (import java.util.Base64)
java.util.Base64
user> (let [encoder (Base64/getUrlEncoder)]
(String. (.encode encoder (.getBytes "Hello StackOverflow"))))
"SGVsbG8gU3RhY2tPdmVyZmxvdw=="
The output contain padding as well( two equal sign at last ). I want to remove padding from my output. https://docs.oracle.com/javase/8/docs/api/java/util/Base64.Encoder.html#withoutPadding-- I know this is useful to solve my problem but I'm not able to figure out how to use withoutPadding() function in clojure. I tried something like this:
user> (let [encoder (Base64/getUrlEncoder))]
(doto (java.util.Base64/Encoder (.withoutPadding (String. (.encode encoder (.getBytes "Hello StackOverflow"))))))
But this is wrong. can anyone tell exact solution? Thanks.
You have to call withoutPadding
on the Encoder itself:
user> (import java.util.Base64)
java.util.Base64
user> (let [encoder (Base64/getUrlEncoder)]
(String. (.encode encoder (.getBytes "Hello StackOverflow"))))
"SGVsbG8gU3RhY2tPdmVyZmxvdw=="
user> (let [encoder (.withoutPadding (Base64/getUrlEncoder))]
(String. (.encode encoder (.getBytes "Hello StackOverflow"))))
"SGVsbG8gU3RhY2tPdmVyZmxvdw"
