go語(yǔ)言是一種快速、簡(jiǎn)單和輕量級(jí)的編程語(yǔ)言。它在處理JSON數(shù)據(jù)方面非常強(qiáng)大和靈活。
go語(yǔ)言中提供了內(nèi)置的encoding/json包,可以輕松地將結(jié)構(gòu)化數(shù)據(jù)序列化為JSON格式,或?qū)SON數(shù)據(jù)反序列化為結(jié)構(gòu)化數(shù)據(jù)。
以下是一個(gè)將go結(jié)構(gòu)體轉(zhuǎn)換為JSON格式的示例:
type Person struct { Name string `json:"name"` Age int `json:"age"` Address Address `json:"address"` } type Address struct { City string `json:"city"` State string `json:"state"` Country string `json:"country"` } p := Person{ Name: "John Doe", Age: 30, Address: Address{ City: "New York", State: "NY", Country: "USA", }, } b, err := json.Marshal(p) if err != nil { log.Fatalln("Failed to marshal person:", err) } fmt.Println(string(b))
輸出結(jié)果:
{"name":"John Doe","age":30,"address":{"city":"New York","state":"NY","country":"USA"}}
除了將go結(jié)構(gòu)體序列化為JSON格式之外,go語(yǔ)言中還可以將JSON數(shù)據(jù)反序列化為結(jié)構(gòu)體,如下所示:
var p Person err := json.Unmarshal([]byte(`{"name":"John Doe","age":30,"address":{"city":"New York","state":"NY","country":"USA"}}`), &p) if err != nil { log.Fatalln("Failed to unmarshal JSON:", err) } fmt.Println(p.Name) fmt.Println(p.Age) fmt.Println(p.Address.City)
輸出結(jié)果:
John Doe 30 New York
總之,go語(yǔ)言在處理JSON數(shù)據(jù)方面非常強(qiáng)大和方便。使用內(nèi)置的encoding/json包,可以輕松地序列化和反序列化JSON數(shù)據(jù)。
