Functions

func ConvertIdentifier

func ConvertIdentifier(s string) string

func CreateDir

func CreateDir(dir string) error

func Decrypt

func Decrypt(encoded string, key []byte) ([]byte, error)

Decrypt decrypts a base64-encoded ciphertext using AES encryption with a given key. It returns the plaintext.

func Encrypt

func Encrypt(plaintext, key []byte) (string, error)

Encrypt encrypts plaintext using AES encryption with a given key. It returns a base64-encoded ciphertext.

func GormErrorWithLogger

func ReadPartFile

func ReadPartFile(path string) ([]string, error)

ReadPartFile read part of file: top 50 lines and bottom 50 lines

func RelativePathBaseOn

func RelativePathBaseOn(basePath, filePath string) string

RelativePathBaseOn changes relative path base on the basePath

func Zip

func Zip(srcFile string, destZip string) error

Zip ZIP 压缩
