What are the methods of serialization and deserialization in golang

Serialization and deserialization in Go language can be achieved by converting data into byte stream format. Common methods include "JSON serialization and deserialization" and "XML serialization and deserialization" , "gob serialization and deserialization" and "Protocol Buffers serialization and deserialization" four types: 1. Use "json.Marshal()" to serialize the data structure into a byte stream in JSON format; 2. Use xml.Marshal() serializes the data structure into a byte stream in XML format, and so on.

#In the Go language, serialization and deserialization are usually implemented by converting data into a byte stream (or other transportable format). The following are several commonly used serialization and deserialization methods:

1. JSON serialization and deserialization: Go language has a built-in standard library encoding/json, and you can use json.Marshal() to convert data The structure is serialized into a JSON-formatted byte stream. Use json.Unmarshal() to deserialize the JSON-formatted byte stream into a data structure.

import "encoding/json"

// 序列化为JSON
data, err := json.Marshal(obj)

// 反序列化JSON
err = json.Unmarshal(data, &obj)

2. XML serialization and deserialization: Go language has a built-in standard library encoding/xml, and you can use xml.Marshal() to serialize the data structure into a byte stream in XML format. , use xml.Unmarshal() to deserialize an XML-formatted byte stream into a data structure.

import "encoding/xml"

// 序列化为XML
data, err := xml.Marshal(obj)

// 反序列化XML
err = xml.Unmarshal(data, &obj)

3. gob serialization and deserialization: Go language has built-in standard library encoding/gob, you can use gob.NewEncoder() and gob.NewDecoder() to create encoders and decoders , call the Encode() and Decode() methods for serialization and deserialization respectively.

import "encoding/gob"

// 序列化为字节流
var buffer bytes.Buffer
encoder := gob.NewEncoder(&buffer)
err = encoder.Encode(obj)
data := buffer.Bytes()

// 反序列化字节流
decoder := gob.NewDecoder(bytes.NewReader(data))
err = decoder.Decode(&obj)

4. Protocol Buffers (protobuf) serialization and deserialization: Go language provides a third-party library github.com/golang/protobuf/proto, which can use the protobuf protocol for efficient serialization ization and deserialization.

import "github.com/golang/protobuf/proto"

// 序列化为字节流
data, err := proto.Marshal(obj)

// 反序列化字节流
err = proto.Unmarshal(data, obj)

The above are some commonly used serialization and deserialization methods. Choose the appropriate method according to specific needs and scenarios.
