我正在尝试制作一个java程序来打开我的PC上的文件和应用程序,现在问题只出现在我尝试从这个程序打开一个蒸汽游戏(即Planetside 2或Terraria)时。我尝试过使用Runtime,但也失败了。这是我试图打开游戏的地方:
public void mousePressed(MouseEvent e) {
try {
Desktop.getDesktop().browse(new URL(path).toURI());
} catch (URISyntaxException | IOException e1) {
try {
Desktop.getDesktop().open(new File(path));
} catch (IOException e2) {
e2.printStackTrace();
}
e1.printStackTrace();
}
}
如果有人可以尝试解决这个问题,我们将不胜感激!
这是输出错误:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: The file: steam:\rungameid\218230 doesn't exist.
路径变量是" steam:// rungameid / 218230"。
答案 0 :(得分:0)
您必须通过Steam.exe
来指示app id
进程打开游戏,或者可以使用steam
协议:
import lombok.val;
import java.io.IOException;
import java.net.URI;
import java.util.ArrayList;
import static java.awt.Desktop.getDesktop;
import static java.util.Arrays.asList;
public class SteamGameExecutor
{
public static final String STEAM_INSTALLATION_PATH = "C:\\Program Files (x86)\\Steam\\Steam.exe";
private static final boolean USE_STEAM_PROTOCOL = true;
public static void startGameById(String id) throws Exception
{
if (USE_STEAM_PROTOCOL)
{
val desktop = getDesktop();
val steamProtocol = new URI("steam://run/" + id);
desktop.browse(steamProtocol);
} else
{
startProcess("-applaunch", id);
}
}
private static void startProcess(String... arguments) throws IOException
{
val allArguments = new ArrayList<String>();
allArguments.add(STEAM_INSTALLATION_PATH);
val argumentsList = asList(arguments);
allArguments.addAll(argumentsList);
val process = new ProcessBuilder(allArguments);
process.start();
}
}
除非版本Linux
/ Mac
上不存在,否则协议版本应更具可移植性/与平台无关。
要找到app id
,可以使用this搜索。例如,以编程方式找到应用ID的实现如下:
import lombok.val;
import java.io.IOException;
import static java.net.URLEncoder.encode;
import static java.nio.charset.StandardCharsets.UTF_8;
import static org.jsoup.Jsoup.connect;
public class SteamAppIdFinder
{
private static final String SEARCH_URL = "https://steamdb.info/search/?a=app&q=";
private static final String QUERY_SELECTOR = "#table-sortable > tbody > tr > td:nth-child(1) > a";
public static String getAppId(String searchTerm) throws IOException
{
val completeSearchURL = SEARCH_URL + encode(searchTerm, UTF_8.name());
val connection = connect(completeSearchURL);
val document = connection.get();
val selectedElements = document.select(QUERY_SELECTOR);
val anchorElement = selectedElements.get(0);
return anchorElement.text();
}
}
