cl-k-takahashi edited a comment on issue #29: Fix the string to sign URL: https://github.com/apache/cloudstack-documentation/pull/29#issuecomment-479715814 @DaanHoogland Current CloudStack contains the code below in ApiServer.java: ``` unsignedRequest = unsignedRequest.toLowerCase(); final Mac mac = Mac.getInstance("HmacSHA1"); final SecretKeySpec keySpec = new SecretKeySpec(secretKey.getBytes(), "HmacSHA1"); mac.init(keySpec); mac.update(unsignedRequest.getBytes()); ``` As you can see, CloudStack generates hash for lower cased request. Current documentation is not problematic for [a-zA-Z0-9] but is problematic for urlencoded characters: ``` >>> urllib.quote_plus('aBcDe'.lower()) 'abcde' >>> urllib.quote_plus('aBcDe').lower() 'abcde' >>> urllib.quote_plus('aBcDe★'.lower()) 'abcde%E2%98%85' >>> urllib.quote_plus('aBcDe★').lower() 'abcde%e2%98%85' ``` The 3rd result contains upper-case characters which causes verification failure in CloudStack management server.
