UE C++获取本机IP地址

开发环境

UE 5.2.1

Visual Studio 2019 16.11.19

代码部分

XXX.Build.cs文件添加以下依赖：

PrivateDependencyModuleNames.AddRange(new String[]{"Sockets"})

.cpp文件：

#include "SockerSubsystem.h"

void GetIp() {
	bool bBind = false;
	TSharedRef<FInternetAddr> LocalAddr = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->GetLocalHostAddr(*GLog, bBind);
	FString LocalIp = "0.0.0.0";
	if (LocalAddr->IsValid()) {
		LocalIp = LocalAddr->ToString(false);
	}
	UE_LOG(LogTemp, Warning, TEXT("LOCAL_IP: %s"), *LocalIp);
}

结果

注：Andriod平台可能获取失败
