arrays - 构建对象的Json对象并将其写入文件

Question

我正在尝试获取从Go API接收到的字符串数组，并将它们以怪异的json列表格式写入文件。没有括号[]，因此我必须为数组中的每个字符串值创建一个“维”。我正在尝试使用类型/结构来做到这一点，但我一直陷于困境(Go的新手)。我应该尝试仅使用 map ，还是有办法实现？

这是我现在正在使用的代码:

package main

import (
    "fmt"
    "io/ioutil"
)

type Dimension struct {
    SQL, Type string
}

type Measure struct {
    Type         string
    DrillMembers []string
}

func check(e error) {
    if e != nil {
        panic(e)
    }
}

func main() {
    a := []string{"country", "year", "gdpPercap", "lifeExp", "pop", "continent"}
    cubeSchema := "measures: {\n  count: {\n    type: `count`,\n    drillMembers: "
    for i, s := range a {
        cubeSchema += s
        fmt.Println(cubeSchema)
        fmt.Println(i)
    }

    fileText := []byte(cubeSchema)
    fmt.Println(cubeSchema)
    err := ioutil.WriteFile("test.js", fileText, 0644)
    check(err)
}

这就是我需要的输出看起来:

measures: {
    count: {
      type: `count`,
      drillMembers: [country]
    }
  },

  dimensions: {
    country: {
      sql: `country`,
      type: `string`
    },

    year: {
      sql: `year`,
      type: `string`
    },

    gdppercap: {
      sql: `gdppercap`,
      type: `string`
    },

    lifeexp: {
      sql: `lifeexp`,
      type: `string`
    },

    pop: {
      sql: `pop`,
      type: `string`
    },

    continent: {
      sql: `continent`,
      type: `string`
    }
  }

现在，我一直被以下输出卡住:

measures: {
  count: {
    type: `count`,
    drillMembers: countryyeargdpPercaplifeExppopcontinent

package main

import (
    "fmt"
    "io/ioutil"
)

func check(e error) {
    if e != nil {
        panic(e)
    }
}

func main() {
    schema := `measures: {
    count: {
      type: 'count',
      drillMembers: [country]
    }
  },

  dimensions: {
  `
    a := []string{"country", "year", "gdpPercap", "lifeExp", "pop", "continent"}
    var cubeSchema string
    for _, s := range a {
        cubeSchema += s + ": {\n\tsql: " + s + ",\n\ttype: `string`\n},\n"
    }

    fileText := []byte(schema + cubeSchema + "}\n}")
    fmt.Println(cubeSchema)
    err := ioutil.WriteFile("test.js", fileText, 0644)
    check(err)
}
