Go语言中比较两个map[string]interface{}是否相等

func main() {
    a := map[string]interface{}{
        "orange": "1",
        "apple":  "2",
        "banana": "3",
    }
    fmt.Println("第一遍：")
    for k, v := range a {
        fmt.Print(k + " : ")
        fmt.Println(v)
    }
    fmt.Println("第二遍：")
    for k, v := range a {
        fmt.Print(k + " : ")
        fmt.Println(v)
    }
}

func CompareTwoMapInterface(data1 map[string]interface{}, 
                        data2 map[string]interface{}) bool {
    keySlice := make([]string, 0)
    dataSlice1 := make([]interface{}, 0)
    dataSlice2 := make([]interface{}, 0)
    for key, value := range data1 {
        keySlice = append(keySlice, key)
        dataSlice1 = append(dataSlice1, value)
    }
    for _, key := range keySlice {
        if data, ok := data2[key]; ok {
            dataSlice2 = append(dataSlice2, data)
        } else {
            return false
        }
    }
    dataStr1, _ := json.Marshal(dataSlice1)
    dataStr2, _ := json.Marshal(dataSlice2)
    return string(dataStr1) == string(dataStr2)
}
