Key Patterns

核心特性

  • jwt_decode
    shows header, payload, and checks if expired — does NOT verify signatures
  • hash
    defaults to SHA-256;
    hash_all
    runs md5, sha1, sha256, sha384, sha512 at once
  • cron_next
    shows the next N scheduled run times — useful for validating cron schedules
  • uuid_generate
    can create multiple UUIDs in one call (pass
    count
    parameter)
  • json_validate
    reports whether input is valid JSON and its root type (object, array, etc.)
  • jwt_decode
    会显示头部、负载信息,并检查是否过期——但不验证签名
  • hash
    默认使用SHA-256算法;
    hash_all
    会同时运行md5、sha1、sha256、sha384、sha512算法
  • cron_next
    会显示接下来N次计划运行时间——适用于验证cron调度
  • uuid_generate
    可在一次调用中生成多个UUID(传入
    count
    参数)
  • json_validate
    会报告输入是否为有效JSON及其根类型(对象、数组等)
