Service Interface Methods
type UtilService interface {
Service
Nanoid(args ...int) string // Get a nanoid unique ID, the parameter is of type int, e.g., util.Nanoid(32) gets a 32-byte length unique ID, default is 21 bytes
Direct(v reflect.Value) reflect.Value // The opposite of reflect.Indirect, i.e., get the pointer variable of the value
SetEnv(env, key, value string) error // Modify and set the value of .env.xxx
SecretKey(length int) (string, error) // Get a random secret key
ExcpKey() string // Get the key for the exception cache value
BlackTokenKey(nanoid string) string // Get the cache key for the JWT blacklist token
Ptr(v any) any // Return the pointer of any basic scalar type value
CreateDir(dir string) string // Recursively create a directory if it does not exist
IsExist(file string) bool // Check if a file or directory exists
Usage Examples
id := util.Nanoid(21)
v := util.Direct(relValue)
err := util.SetEnv(".env.dev", "APP_NAME", "Test")
key, err := util.SecretKey(32)
excpKey := util.ExcpKey()
tokenKey := util.BlackTokenKey(util.Nanoid(21))
p := util.Ptr("test").(*string)
dir := util.CreateDir(dir)
ok := util.IsExist("/path/file.txt")
