kotlin - 使用 Compose for Desktop 在浏览器中打开链接

Question

如果单击按钮，如何在浏览器中打开链接。我正在为此使用Compose for Desktop。

Button(onClick = {
    // What I have to write here..
}) {
    Text(
        text = "Open a link",
        color = Color.Black
    )
}

提前致谢。

使用Desktop#browse(URI)方法。它在用户的默认浏览器中打开一个 URI。

public static boolean openWebpage(URI uri) {
    Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
    if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE)) {
        try {
            desktop.browse(uri);
            return true;
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    return false;
}

public static boolean openWebpage(URL url) {
    try {
        return openWebpage(url.toURI());
    } catch (URISyntaxException e) {
        e.printStackTrace();
    }
    return false;
}

受https://stackoverflow.com/a/54869038/1575096的启发，也可以在 Linux 和 Mac 上工作：

fun openInBrowser(uri: URI) {
    val osName by lazy(LazyThreadSafetyMode.NONE) { System.getProperty("os.name").lowercase(Locale.getDefault()) }
    val desktop = Desktop.getDesktop()
    when {
        Desktop.isDesktopSupported() && desktop.isSupported(Desktop.Action.BROWSE) -> desktop.browse(uri)
        "mac" in osName -> Runtime.getRuntime().exec("open $uri")
        "nix" in osName || "nux" in osName -> Runtime.getRuntime().exec("xdg-open $uri")
        else -> throw RuntimeException("cannot open $uri")
    }
}

Button(onClick = { openInBrowser(URI("https://domain.tld/page")) }) {
    Text(
        text = "Open a link",
        color = Color.Black
    )
}
