以下是使用 C++ 代码将应用程序添加到 Windows 防火墙白名单的步骤:
1. 包含Windows防火墙API头文件:
```c++
#include <Windows.h>
#include <netfw.h>
#pragma comment( lib, "ole32.lib" )
#pragma comment( lib, "oleaut32.lib" )
#pragma comment( lib, "netfw.lib" )
```
2. 创建一个新的NetFwRule对象:
```c++
INetFwRule* fwRule = NULL;
CoCreateInstance(__uuidof(NetFwRule), NULL, CLSCTX_INPROC_SERVER, __uuidof(INetFwRule), (void**)&fwRule);
```
3. 设置防火墙规则的属性:
```c++
fwRule->put_Name(L"My Firewall Rule"); // 设置规则名称
fwRule->put_Description(L"Allow incoming traffic on port 1234"); // 设置规则描述
fwRule->put_ApplicationName(L"C:\\Path\\To\\My\\App.exe"); // 设置应用程序路径
fwRule->put_Protocol(NET_FW_IP_PROTOCOL_TCP); // 设置协议类型
fwRule->put_LocalPorts(L"1234"); // 设置本地端口
fwRule->put_Action(NET_FW_ACTION_ALLOW); // 允许入站流量
fwRule->put_Enabled(VARIANT_TRUE); // 启用规则
```
4. 获取防火墙管理器对象:
```c++
INetFwPolicy2* fwPolicy2 = NULL;
HRESULT hr = CoCreateInstance(__uuidof(NetFwPolicy2), NULL, CLSCTX_INPROC_SERVER, __uuidof(INetFwPolicy2), (void**)&fwPolicy2);
```
5. 将防火墙规则添加到白名单中:
```c++
hr = fwPolicy2->get_Rules(&fwRules);
hr = fwRules->Add(fwRule);
```
6. 释放资源:
```c++
fwPolicy2->Release();
fwRules->Release();
fwRule->Release();
```
完整代码示例:
```c++
#include <Windows.h>
#include <netfw.h>
#pragma comment( lib, "ole32.lib" )
#pragma comment( lib, "oleaut32.lib" )
#pragma comment( lib, "netfw.lib" )
int main()
{
HRESULT hr = S_OK;
INetFwPolicy2* fwPolicy2 = NULL;
INetFwRules* fwRules = NULL;
INetFwRule* fwRule = NULL;
// 创建防火墙规则对象
hr = CoCreateInstance(__uuidof(NetFwRule), NULL, CLSCTX_INPROC_SERVER, __uuidof(INetFwRule), (void**)&fwRule);
if (SUCCEEDED(hr))
{
// 设置规则属性
fwRule->put_Name(L"My Firewall Rule");
fwRule->put_Description(L"Allow incoming traffic on port 1234");
fwRule->put_ApplicationName(L"C:\\Path\\To\\My\\App.exe");
fwRule->put_Protocol(NET_FW_IP_PROTOCOL_TCP);
fwRule->put_LocalPorts(L"1234");
fwRule->put_Action(NET_FW_ACTION_ALLOW);
fwRule->put_Enabled(VARIANT_TRUE);
// 获取防火墙管理器对象
hr = CoCreateInstance(__uuidof(NetFwPolicy2), NULL, CLSCTX_INPROC_SERVER, __uuidof(INetFwPolicy2), (void**)&fwPolicy2);
if (SUCCEEDED(hr))
{
hr = fwPolicy2->get_Rules(&fwRules);
if (SUCCEEDED(hr))
{
// 将规则添加到防火墙白名单中
hr = fwRules->Add(fwRule);
}
fwRules->Release();
fwPolicy2->Release();
}
fwRule->Release();
}
if (FAILED(hr))
{
printf("Failed to add firewall rule\n");
}
else
{
printf("Firewall rule added successfully\n");
}
return 0;
}
```
请注意,您需要以管理员身份运行应用程序才能将防火墙规则添加到白名单中。
