java HttpServer在HttpHandler中接收大文件

Question

我正在为我的应用程序构建一个快速HTTP服务器，并且需要接收一个大文件（7z存档-250MB至1GB）。

服务器基于com.sun.net.httpserver.HttpServer和com.sun.net.httpserver.HttpHandler。

到目前为止，我进行了以下操作，这些操作显然不起作用-它可以接收44个字节并完成操作。

@Override
public void handle(HttpExchange httpExchange) throws IOException
{
    String requestMethod = httpExchange.getRequestMethod();

    if (requestMethod.equalsIgnoreCase("POST"))
    {
        Headers responseHeaders = httpExchange.getResponseHeaders();
        responseHeaders.set("Content-Type", "text/plain");
        httpExchange.sendResponseHeaders(200, 0);

        InputStream inputStream = httpExchange.getRequestBody();
        byte[] buffer = new byte[4096];
        int lengthRead;
        int lengthTotal = 0;
        FileOutputStream fileOutputStream = new FileOutputStream(FILENAME);

        while ((lengthRead = inputStream.read(buffer, 0, 4096)) > 0)
        {
            fileOutputStream.write(buffer, 0, lengthRead);
            lengthTotal += lengthRead;
        }

        fileOutputStream.close();

        System.out.println("File uploaded - " + lengthTotal + " bytes total.");

        httpExchange.getResponseBody().close();
    }
}

请求如下所示：

我如何收到文件？
