Constants

const (
	// 时间格式化字符串
	SysTimeform      string = "2006-01-02 15:04:05"
	SysTimeformShort string = "2006-01-02"
)

前面是含义，后面是 go 的表示值,多种表示,逗号","分割 年　 06,2006 月份 1,01,Jan,January 日　 2,02,_2 时　 3,03,15,PM,pm,AM,am 分　 4,04 秒　 5,05 周几 Mon,Monday 时区时差表示 -07,-0700,Z0700,Z07:00,-07:00,MST 时区字母缩写 MST 您看出规律了么！哦是的，你发现了，这里面没有一个是重复的，所有的值表示都唯一对应一个时间部分。 并且涵盖了很多格式组合。

Variables

Functions

func AESDecrypt

func AESDecrypt(baseStr string) string

----------------------------------------------------------- ----------------------- 解密 ------------------------------ ----------------------------------------------------------- 先base64转码，再解密

func AESDecrypt2

func AESDecrypt2(cipherkey, ciphertext []byte) ([]byte, error)

AESDecrypt decrypts a piece of data. The cipherkey argument should be the AES key, either 16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.

func AESEncrypt

func AESEncrypt(originPWD []byte) string

----------------------------------------------------------- ----------------------- 加密 ------------------------------ ----------------------------------------------------------- 加密后再base64编码成string

func AESEncrypt2

func AESEncrypt2(cipherkey, src []byte) []byte

AESEncrypt encrypts a piece of data. The cipherkey argument should be the AES key, either 16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.

func Check

func Check(a interface{})

结构体指针检查验证，如果传入的interface为nil，就通过log.Panic函数抛出一个异常 被用在starter中检查公共资源是否被实例化了
