Maybe it's me, but I would think that this question would benefit from more detail, more real code, and removal of the GitHub link. All pertinent information should be in the question itself, such as a minimal reproducible example code post, and not in a link.

也许是我的问题，但我认为这个问题将受益于更多的细节，更真实的代码，以及删除GitHub链接。所有相关信息都应该在问题本身中，例如一个最小的可重现的示例代码帖子，而不是在链接中。

Oh, I thought I only use jdk classes. Did u see any legal issues?

哦，我还以为我只用JDK类呢。你看到什么法律问题了吗？

What do you mean by "legal issues"? This site is a software Q&A site and does not delve into legal issues, other than that intellectual property rights must be respected. That's it.

你所说的“法律问题”是什么意思？本网站是一个软件问答网站，除了知识产权必须得到尊重外，不会深入探讨法律问题。就这样。

To be safe I am removing github redirection.

为了安全起见，我正在删除GitHub重定向。

If you put an index file (index.html or index.htm) in the directory, then that will be served, rather than the directory contents.

如果您将索引文件(index.html或index.htm)放在目录中，则将提供该索引文件，而不是目录内容。


One more thing: you probably want a / at the end of the context path (so "/file/") as per the note in the API:

还有一件事：根据API中的说明，您可能需要在上下文路径的末尾添加一个/(即“/file/”)：



The path should generally, but is not required to, end with '/'. If the path does not end with '/', eg such as with "/foo" then this would match requests with a path of "/foobar" or "/foo/bar".



Alternatively:

或者：


var server = HttpServer.create(new InetSocketAddress(8080), 2);
var fileHandler = SimpleFileServer.createFileHandler(Path.of("d:\file"));
server.createContext("/file/", (exchange) -> {
    if (exchange.getHttpContext().getPath().equals(exchange.getRequestURI().getPath())) {
        try (exchange) {
            exchange.setAttribute("request-path", "could not resolve request URI path");
            exchange.sendResponseHeaders(404, 0);
        }
    } else {
        fileHandler.handle(exchange);
    }
});
server.start();

Thank you. Before "fileHandler.handle(exchange);", adding "if (file not exists) return;" helped a lot.

谢谢。在“fileHandler.Handle(Exchange)；”之前，加上“if(FILE NOT EXISTS)RETURN；”很有帮助。
