Overview

goo.go this file incloud the common functions,maps slices, structs or anything else.

mysql.go has add delete search ect about the mysql using go-sql-driver/mysql.

salt.go This file is all about encrypting and decrypting passwords. this is a example for you:

pass,salt := EncryptMd5("991182@")
passReal := "991182@"
a,b := DeEncryptMd5(passReal,pass,salt)
if b != nil || !a {
	t.Error("❌")
}
fmt.Println(pass,salt)
passErr := "123456!@"
d,e := DeEncryptMd5(passErr,pass,salt)
if e != nil || !d {
	t.Error("这个错误 应该被打印出来")
}

Functions

func ConvertToString

func ConvertToString(src string, srcCode string, tagCode string) string

转码 将文字 从 比如 gbk转化为 utf8

func DeEncryptArgon2

func DeEncryptArgon2(password, resultDB, saltDB string) (is bool, err error)

Verify that the user's password is equal to the password in the database

func DeEncryptMd5

func DeEncryptMd5(password string, resultDB, saltDB string) (is bool, err error)

Verify that the user's password is equal to the password in the database

Example

pass, salt := EncryptMd5("991182@")
passReal := "991182@"
a, b := DeEncryptMd5(passReal, pass, salt)
if b != nil || !a {
	fmt.Println("x")
	//	output:x
}
passErr := "123456!@"
d, e := DeEncryptMd5(passErr, pass, salt)
if e != nil || !d {
	fmt.Println("err")
	

Output:

err

func EncryptArgon2

set cookie

Types

type Data

type Data struct {
	Data Values `json:"data"`
}

type IntSet

type IntSet struct {
	Words []uint64 // bit array
}

InSet is a bit array struct.

func (*IntSet) Clear

func (i *IntSet) Clear()

clear the array,and let i.Words point a new slice.

func (*IntSet) Copy

func (i *IntSet) Copy() *IntSet

copy form the old array to a new array,return a new instance's pointer.

func (*IntSet) Len

func (i *IntSet) Len() int

Len return a int type value about the bit array's length.

func (*IntSet) Remove

func (i *IntSet) Remove(x int)

remove this array's one bit.

type Session

type Session interface {
	Get(key interface{}) interface{}
	Set(key, value interface{}) error
	Delete(key interface{}) error
	SessionID() string
}

Session interface

func NewSession

func NewSession() Session

newSession new a session object.

type SessionStore

type SessionStore struct {
	// contains filtered or unexported fields
}

the main manager about the session system

func (*SessionStore) Delete

func (s *SessionStore) Delete(key interface{}) error

func (*SessionStore) Get

func (s *SessionStore) Get(key interface{}) interface{}
