當嘗試在 go 中追加迭代的值時，該函數(shù)將最后一次迭代追加 4 次。例如，我正在嘗試將包含網(wǎng)卡數(shù)據(jù)的字符串解析為地圖，并且在迭代時僅附加最后一個：這是帶有代碼的游樂場鏈接： https ://go.dev/play/p/mKtFvK36PMnpackage mainimport ( "fmt" "strings")type Foo struct { val int}func main() { NetworkJson := "4 NIC(s) Installed.,[01]: Realtek PCIe GbE Family Controller, Connection Name: Ethernet, DHCP Enabled: Yes, DHCP Server: 10.101.10.13, IP address(es), [01]: 10.1.2.62,[02]: VirtualBox Host-Only Ethernet Adapter, Connection Name: VirtualBox Host-Only Network, DHCP Enabled: No, IP address(es), [01]: 192.168.56.1, [02]: fe80::4c17:978a:2c91:8e27,[03]: VMware Virtual Ethernet Adapter for VMnet1, Connection Name: VMware Network Adapter VMnet1, DHCP Enabled: Yes, DHCP Server: 192.168.146.254, IP address(es), [01]: 192.168.146.1, [02]: fe80::88b4:d443:2ab8:59b5,[04]: VMware Virtual Ethernet Adapter for VMnet8, Connection Name: VMware Network Adapter VMnet8, DHCP Enabled: Yes, DHCP Server: 192.168.128.254, IP address(es), [01]: 192.168.128.1, [02]: fe80::a40d:e64:fa9f:e82f" var IPs []string var Data []string var IPMap = make(map[string]string) var CardMap = make(map[string]interface{}) var CardIP = make(map[string][]map[string]string) var NetCard = make(map[string][]interface{}) // Faz loop entre as placas de rede for _, Cards := range strings.Split(string(NetworkJson), ",[") { // Faz loop entre os dados de cada placa for _, CardData := range strings.Split(string(Cards), ",") { // Verifica se dado inicia com espa?o em branco if strings.HasPrefix(CardData, " ") { // Verifica se dado sem o espa?o em branco come?a com [ if strings.HasPrefix(strings.TrimSpace(CardData), "[") { } } }

您將所有內(nèi)容都存儲到同一個地圖變量 CardMap 中，并且您使用的是單數(shù)鍵“Card Name”。append(NetCard["Cards"], CardMap)不執(zhí)行 CardMap 的深拷貝，僅附加淺拷貝，因此每次迭代都會更新淺拷貝的數(shù)據(jù)。你的其他變量有同樣的問題。
將變量聲明移動到主循環(huán)中：
var NetCard = make(map[string][]interface{})
// Faz loop entre as placas de rede
for _, Cards := range strings.Split(string(NetworkJson), ",[") {
var IPs []string
var Data []string
var IPMap = make(map[string]string)
var CardMap = make(map[string]interface{})
var CardIP = make(map[string][]map[string]string)
// Faz loop entre os dados de cada placa
for _, CardData := range strings.Split(string(Cards), ",") {
// ...
