我使用$./airports.py --full
{'city': 'London','name': 'Heathrow', 'code': 'LHR'}
...
$./airports.py --city --code
{'city': 'London', 'code': 'LHR'}
...
$./airports.py --city --code --full
Error: '--city' and '--code' can't be used with '--full'
，并希望检查Kafka消费者在特定群体的话题上的滞后性
Kafka 2.0.0 (Commit:3402a8361b734732)但它返回以下错误：
kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --topic imdb.title --zookeeper localhost:2181 --group decisionwanted
如何正确获取此Kafka版本的滞后值？
答案 0 :(得分：1)
此类显然已在1.0中删除。使用<?php
class MBM_Encrypt_Decrypt {
const ENCRYPT_METHOD = 'AES-256-CBC'; // type of encryption
const SECRET_KEY = '13GsJd6076v69^f4(fdB'; // secret key
const SECRET_IV = 'fg3Dk54f4340fKF2JTC9'; // secret iv
public function encrypt($string) {
return $this->encrypt_decrypt('encrypt', $string);
}
public function decrypt($string) {
return $this->encrypt_decrypt('decrypt', $string);
}
private function encrypt_decrypt($action, $string)
{
$key = hash('sha256', self::SECRET_KEY);
$iv = substr(hash('sha256', self::SECRET_IV), 0, 16);
if ($action == 'encrypt') {
$output = openssl_encrypt($string, self::ENCRYPT_METHOD, $key, 0, $iv);
} else if ($action == 'decrypt') {
$output = openssl_decrypt(base64_decode($string), self::ENCRYPT_METHOD, $key, 0, $iv);
}
$output = (!empty($output)) ? $output : false;
return $output;
}
}
$class_encrypt = new MBM_Encrypt_Decrypt();
$plain_txt = "xyz@abc.com";
echo 'Plain Text: ' . $plain_txt . PHP_EOL;
$decrypted_txt = $class_encrypt->decrypt("ZHRodkpCK3R5QXlCMnh3MFdudDh3Zz09");
echo 'Decrypted Text: ' . $decrypted_txt . PHP_EOL;
if ($plain_txt === $decrypted_txt) echo 'SUCCESS' . PHP_EOL;
else echo 'FAILED' . PHP_EOL;
echo PHP_EOL . 'Length of Plain Text: ' . strlen($plain_txt);
echo PHP_EOL . 'Length of Encrypted Text: ' . strlen($encrypted_txt). PHP_EOL;
