Java使用HMAC-SHA1算法详解编程语言

String secret = mConsumerSecret + "&" + mOauthToken; 
 
SecretKey secretKey = new SecretKeySpec(secret.getBytes("US-ASCII"), "HmacSHA1"); 
Mac mac = Mac.getInstance("HmacSHA1"); 
mac.init(secretKey); 
 
byte[] text = builder.toString().getBytes("US-ASCII"); 
byte[] finalText = mac.doFinal(text); 
String base64Text = Base64.encodeToString(finalText, Base64.DEFAULT); 
return encode(base64Text.trim());
