本文介绍了Golang序列化和反序列化回来的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
例如,如果我有这个结构体,那么在Golang中将最好的方法(完整性和性能)序列化并反序列化为字符串,反之亦然?
struct Session {
属性map [string] interface {}
权限[] int64
}
我想将它存储在并将其取回。我试图保存,int和字符串,没问题,但如何存储结构对象?
conn:= redisConnectors.Get ()
//示例
,err:= conn.Do(`SETEX`,`uid_key`,EXPIRE_SEC,user_id)
_,err = conn.Do(`SETEX`,`email_key`,EXPIRE_SEC,login_email)
//获取示例
user_id,err:= redis.Int64(conn.Do `GET`,`uid_key`))
login_email,err:= redis.String(conn.Do(`GET`,`email_key`))
解决方案
使用可以解决问题,例如:
<$
encoding / base64
encoding / gob
bytes
)
类型SX map [string] interface {}
//二进制编码器
func ToGOB64(m SX)字符串{
b:= bytes.Buffer {}
e: = gob.NewEncoder(& b)
err:= e.En代码(m)
if err!= nil {fmt.Println(`failed gob Encode`,err)}
return base64.StdEncoding.EncodeToString(b.Bytes())
}
//去二进制解码器
func FromGOB64(str string)SX {
m:= SX {}
by,err:= base64.StdEncoding.DecodeString(str)
if err!= nil {fmt.Println(`failed base64 Decode`,err); }
b:= bytes.Buffer {}
b.Write(by)
d:= gob.NewDecoder(&b)
err = d.Decode(& m)
if err!= nil {fmt.Println(`failed gob Decode`,err); }
return m
}
当您需要序列化自定义结构或类型(例如 Session
struct),只需添加以下几行:
func init(){
gob.Register(SX {})
gob.Register(Session {})
}
What's the best way (completeness and performance) in Golang to serialize and deserialize a struct to string and vice versa?
for example, if I have this struct:
struct Session {
Properties map[string]interface{}
Permissions []int64
}
I want to store it on Redis and fetch it back. I have tried to save, int and string, it's fine, but how to store struct object?
conn := redisConnectors.Get()
// set example
_, err := conn.Do(`SETEX`, `uid_key`, EXPIRE_SEC, user_id)
_, err = conn.Do(`SETEX`, `email_key`, EXPIRE_SEC, login_email)
// get example
user_id, err := redis.Int64(conn.Do(`GET`, `uid_key`))
login_email, err := redis.String(conn.Do(`GET`, `email_key`))
解决方案
Using gob and base64 could solve the problem, for example:
import (
"encoding/base64"
"encoding/gob"
"bytes"
)
type SX map[string]interface{}
// go binary encoder
func ToGOB64(m SX) string {
b := bytes.Buffer{}
e := gob.NewEncoder(&b)
err := e.Encode(m)
if err != nil { fmt.Println(`failed gob Encode`, err) }
return base64.StdEncoding.EncodeToString(b.Bytes())
}
// go binary decoder
func FromGOB64(str string) SX {
m := SX{}
by, err := base64.StdEncoding.DecodeString(str)
if err != nil { fmt.Println(`failed base64 Decode`, err); }
b := bytes.Buffer{}
b.Write(by)
d := gob.NewDecoder(&b)
err = d.Decode(&m)
if err != nil { fmt.Println(`failed gob Decode`, err); }
return m
}
and when you need to serialize custom struct or type (for example Session
struct), just add these lines:
func init() {
gob.Register(SX{})
gob.Register(Session{})
}
