我使用json.Marshal接口接受 amap[string]interface{}并將其轉換為 a []byte（這是一個字節數組嗎？）data, _ := json.Marshal(value)log.Printf("%s\n", data)我得到這個輸出{"email_address":"[email protected]","street_address":"123 Anywhere Anytown","name":"joe","output":"Hello World","status":1}底層字節屬于以下聲明的結構type Person struct { Name string `json:"name"` StreetAddress string `json:"street_address"` Output string `json:"output"` Status float64 `json:"status"` EmailAddress string `json:"email_address",omitempty"`}我想獲取data并生成一個類型的變量Person struct我怎么做？

你使用json.Unmarshal：
package main
import (
"encoding/json"
"fmt"
)
type Person struct {
Name string `json:"name"`
StreetAddress string `json:"street_address"`
Output string `json:"output"`
Status float64 `json:"status"`
EmailAddress string `json:"email_address",omitempty"`
}
func main() {
data := []byte(`{"email_address":"[email protected]","street_address":"123 Anywhere Anytown","name":"joe","output":"Hello World","status":1}`)
var p Person
if err := json.Unmarshal(data, &p); err != nil {
panic(err)
}
fmt.Printf("%#v\n", p)
}
輸出：
main.Person{Name:"joe", StreetAddress:"123 Anywhere Anytown", Output:"Hello World", Status:1, EmailAddress:"[email protected]"}
