1、将token、timestamp、nonce三个参数进行字典序排序并拼成一个字符串
public String sort(String token, String timestamp, String nonce) {
String[] strArray = {token, timestamp, nonce};
Arrays.sort(strArray);
StringBuilder sb = new StringBuilder();
for (String str : strArray) {
sb.append(str);
}
return sb.toString();
}
2、对字符串进行sha1加密
public String shal(String str){
try {
MessageDigest digest = MessageDigest.getInstance("SHA-1");
digest.update(str.getBytes());
byte messageDigest[] = digest.digest();
StringBuffer hexString = new StringBuffer();
// 字节数组转换为 十六进制 数
for (int i = 0; i < messageDigest.length; i++) {
String shaHex = Integer.toHexString(messageDigest[i] & 0xFF);
if (shaHex.length() < 2) {
hexString.append(0);
}
hexString.append(shaHex);
}
return hexString.toString();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return "";
}
}
