我正在做的事情有什么问题吗？我不明白为什么所有地图键都被更新，它应该只是“以太”键。

data := []byte(`
    [{".id":"*1","actual-mtu":"1500","default-name":"ether1","disabled":"false","l2mtu":"1514","type":"ether"},{".id":"*2","actual-mtu":"1500","default-name":"bridge2","disabled":"false","l2mtu":"1514","type":"bridge"}] 
`)

var dst []map[string]string
json.Unmarshal(data, &dst)

rxTx := map[string]int{"rx": 0, "tx": 0}
typeMap := map[string]map[string]int{"wlan": rxTx, "ether": rxTx, "bridge": rxTx, "wg": rxTx}

fmt.Println(typeMap)

for _, v := range dst {

    if v["type"] == "ether" {

        typeMap["ether"]["rx"] += 1

        typeMap["ether"]["tx"] += 1
    }
}

fmt.Println(typeMap)

去游乐场

输出将是 map[bridge:map[rx:1 tx:1] ether:map[rx:1 tx:1] wg:map[rx:1 tx:1] wlan:map[rx:1 tx:1]]

但我期待着 map[bridge:map[rx:0 tx:0] ether:map[rx:1 tx:1] wg:map[rx:0 tx:0] wlan:map[rx:0 tx:0]]
