go生成一个复杂的JSON

[hssg44]

我在项目中需要生成一个如下格式的JSON

{"params":
[  [    "data1",    14 ],
   [    "data2",    "red"],
   [    "data3",    "test"] ]
}

其中params是一个不定长的数组，实际当中可能有7-10个list
请问要怎么用go生成这样子的json。

用标准库 "encoding/json"即可

func test1() { s := struct { Params [][]string }{ Params: [][]string{ []string{"1", "2", "3"}, []string{"a", "b", "c"}, []string{"1", "2", "3"}, }, } b, _ := json.Marshal(s) fmt.Println(string(b)) }

func main() {
	js := make(map[string]interface{})
	arrList := make([]interface{}, 0)

	arr1 := make([]interface{}, 0)
	arr1 = append(arr1, "data1")
	arr1 = append(arr1, 14)

	arr2 := make([]interface{}, 0)
	arr2 = append(arr2, "data2")
	arr2 = append(arr2, "red")

	arrList = append(arrList, arr1)
	arrList = append(arrList, arr2)

	js["params"] = arrList

	bt, _ := json.Marshal(js)

	fmt.Println(string(bt))
}
