java - Signature with HMAC SHA-256 and Base64Encoder -

i tried lot creating signature access 1 web service.

they required generate signature each request.

for generating signature, have 1 message "abc" , 1 secrete key "xyz". according them signature should processed next ruby code

require 'base64' require 'openssl' secret = "xyz" request = "abc" digest = openssl::digest::digest.new('sha256') signature = base64.encode64(openssl::hmac.digest(digest, secret, request)).chomp

signature should 9zjsfvb3k5npnlf5he+gfyyaxnwcij6j8ycrpxw5gg0= not getting using java code below:

secretkey secretkey = null; byte[] keybytes = keystring.getbytes("utf-8"); mac mac = mac.getinstance("hmachsa256"); secretkey = new secretkeyspec(keybytes,mac.getalgorithm()); mac.init(secretkey); byte[] text = basestring.getbytes("utf-8"); //mac.update(digest.digest()); byte[] encodedtext = mac.dofinal(text); homecoming new string(base64.encodebase64(encodedtext)).trim();

please help me on this.

i ran java code , got oqljgtdh255vg5ix4fjvzhvfoq7tnygjrcbq/enf8je=

i went this online site , got oqljgtdh255vg5ix4fjvzhvfoq7tnygjrcbq/enf8je=

i ran top script ruby script, , got oqljgtdh255vg5ix4fjvzhvfoq7tnygjrcbq/enf8je=

since 3 match, suggest code above consistent value study not correct. above java code pretty much textbook hmacsha256 java cannot comment on ruby part because java guy.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
