我认为我的问题需要对背景进行一些解释。我的任务是创建一个基本服务器，它将在我的系统上发送客户请求的 HTML 文件。我被告知只需输入localhost:8080/index.html我的 Firefox 浏览器作为测试客户端来测试我的服务器。输入该行输入可以正常工作并打印出index.html. 为了安全起见，我应该测试以确保请求的文件直接在我当前的工作范围内，如果不是，我应该拒绝该请求。我已经设置了这样一个捕获，我想检查它。我想index.html再次使用我的文件，但是使用整个路径名，
C:\Users\Gabrielle\Documents\NetBeansProjects\CS2 Assignment 5\src\index.html所以我在浏览器中输入
localhost:8080/C:\Users\Gabrielle\Documents\NetBeansProjects\CS2 Assignment 5\src\index.html
我收到一个错误，说该文件不存在。然后我检查了它试图制作文件的内容以及它试图制作文件的内容，我得到了
C:%5CUsers%5C%5CGabreille%5C%5CDocuments%5C%5CNetBeansProjects%5C%5CCS2%20Assignment%205%5Cindex.html
这显然不是文件的名称。我只是错误地发送了文件名吗？如果它有任何区别，我正在从 Windows 命令提示符运行程序。下面是我的多线程客户端的代码和我的可运行对象的代码。如果您有任何问题或想要澄清，我会密切关注这个线程。
import java.io.*;
import java.net.*;
public class WebServer {
public static void main(String[] args)
