HarmonyOS Base64长字符串如何完整打印出来

可以利用hilog封装log工具类检查日志长度，超出长度就分段打印,如:

class MyLog {
  static e(logTag: string, content: string) {
    const maxSize = 1024;
    if (content.length <= maxSize) {
      // 长度小于等于限制直接打印
      hilog.error(0xFF00, logTag, '%{public}s', content);
    } else {
      while (content.length > maxSize) {
        // 循环分段打印
        let logContent = content.substring(0, maxSize);
        content = content.replace(logContent, '');
        hilog.error(0xFF00, logTag, '%{public}s', logContent); // 打印剩余日志
      }
    }
  }
}

aboutToAppear(): void {
  MyLog.e('test', this.waitingDecryptString);
}

Hilog日志最长支持4096 个字节（包含结束符)
