英文:
Writing a JSON of different types in Go (int and string)
问题
我是你的中文翻译助手，以下是翻译好的内容：
我对Go和Json都不太熟悉，所以可能会漏掉很多要点。
我基本上想做的是编写一个程序，执行简单的Fizz-Buzz程序，并将其转换为JSON格式。
这个程序接受两个整数（a和b），从a到b（i）进行迭代，并输出：
- 如果数字是3的倍数，则输出"Fizz"
- 如果数字是5的倍数，则输出"Buzz"
- 如果数字既是3的倍数又是5的倍数，则输出"FizzBuzz"
- 如果数字既不是3的倍数也不是5的倍数，则输出数字i
使用以下简单的代码片段：
func fizzbuzz(a int, b int) string{
str := fmt.Sprint("{\"output\":[")
for i := a ; i <= b; i++ {
if i%5 == 0 && i%3 == 0 {
str = fmt.Sprint(str, "\"FizzBuzz\"")
} else if i%3 == 0 {
str = fmt.Sprint(str, "\"Fizz\"")
} else if i%5 == 0 {
str = fmt.Sprint(str, "\"Buzz\"")
} else {
str = fmt.Sprint(str, i)
}
str = str + ","
}
str = str[:len(str) - 1]
str = str + "]}"
return str
}
我能够构建出一个字符串，稍后可以将其转换为JSON：
{"output":["FizzBuzz",1,2,"Fizz",4,"Buzz","Fizz",7,8,"Fizz","Buzz",11,"Fizz",13,14,"FizzBuzz"]}
到目前为止，这个方法运行良好。我只是想知道，在Golang中是否有其他方法可以创建一个包含混合类型（整数和字符串）的JSON数组？我尝试过使用结构体和marshaling，但结构体似乎具有固定的结构。
英文:
I'm new to Go and Json, so I might miss a lot of points here.
So what I'm basically trying to do is making a program which performs the simple Fizz-Buzz program and make a JSON out of it.
This program takes two integers (a and b), iterate from a to b (i) and outputs:
- "Fizz" if the number is a factor of 3
- "Buzz" if the number is a factor of 5
- "FizzBuzz" if the number is a factor both and,
- i if the number isn't a factor of both
Using this simple code snippet:
func fizzbuzz(a int, b int) string{
str := fmt.Sprint("{\"output\":[")
for i := a ; i <= b; i++ {
if i%5 == 0 && i%3 == 0 {str = fmt.Sprint(str, "\"FizzBuzz\"")
}else if i%3 == 0 {str = fmt.Sprint(str, "\"Fizz\"")
}else if i%5 == 0 {str = fmt.Sprint(str, "\"Buzz\"")
}else {str = fmt.Sprint(str, i)}
str = str + ","
}
str = str[:len(str) - 1]
str = str + "]}"
return str
}
I was able to construct the string that can later on be converted to JSON:
{"output":["FizzBuzz",1,2,"Fizz",4,"Buzz","Fizz",7,8,"Fizz","Buzz",11,"Fizz",13,14,"FizzBuzz"]}
This works fine so far. I'm just wondering, are there any other solutions to making a JSON array of mixed type (integer and strings) on Golang? I've tried struct and marshaling, but a struct seems to have fixed structure.

有两个好的选择可以考虑。
你可以使用一个接口类型。
package main
import (
"encoding/json"
"os"
)
type output struct {
Output []interface{} `json:"output"`
}
func main() {
out := output{
Output: []interface{}{"FizzBuzz", 1, 2, "Fizz"},
}
d, _ := json.Marshal(out)
os.Stdout.Write(d)
}
输出：
{"output":["FizzBuzz",1,2,"Fizz"]}
或者你可以使用一个不同的 JSON 库，比如 gojay，它有一个不同的 API 用于序列化 JSON。
英文:
There are two good options that come to mind.
You can use an interface type.
package main
import (
"encoding/json"
"os"
)
type output struct {
Output []interface{} `json:"output"`
}
func main() {
out := output{
Output: []interface{}{"FizzBuzz", 1, 2, "Fizz"},
}
d, _ := json.Marshal(out)
os.Stdout.Write(d)
}
Output:
{"output":["FizzBuzz",1,2,"Fizz"]}
Or you can use a different JSON library, like gojay, which has a different API for serializing JSON.
