arrays - 创建 go 结构以接受带有匿名顶级项目的 json

Question

我正在接收这个结构，但不知道如何创建 go 结构以将其编码为:
[
{
“搜索信息”:[
{
“PrefProv”:“68”，
“语言”:“乌兹别克语”
}
]
}
]
如何定义 go 结构以将其解码？

Answer 1

这里有一个例子:

package main

import (
    "encoding/json"
    "fmt"
)

type RawStruct []struct {
    Searchinfo []struct {
        PrefProv string `json:"PrefProv"`
        Language string `json:"Language"`
    } `json:"searchinfo"`
}

func main() {
    raw_data := `[{"searchinfo":[{"PrefProv":"68","Language":"Uzbek"}]}]`
    var rawStruct RawStruct
    if err := json.Unmarshal([]byte(raw_data), &rawStruct); err != nil {
        panic(err.Error())
    }
    fmt.Printf("%+v\n", rawStruct)
    fmt.Println("---------")
    for indexStruct, itemStruct := range rawStruct {
        fmt.Printf("Iterating element [%d] of itemStruct: [%+v]\n", indexStruct, itemStruct)
        for indexInfo, itemInfo := range itemStruct.Searchinfo {
            fmt.Printf("[%d] PrefProv: %s\n", indexInfo, itemInfo.PrefProv)
            fmt.Printf("[%d] Language: %s\n", indexInfo, itemInfo.Language)
        }
    }
}

结果:

[{Searchinfo:[{PrefProv:68 Language:Uzbek}]}]
---------
Iterating element [0] of itemStruct: [{Searchinfo:[{PrefProv:68 Language:Uzbek}]}]
[0] PrefProv: 68
[0] Language: Uzbek
