Java HTTP PHP 服务器

Question

我有一个 Java 应用程序，它在端口 8080 上创建一个本地 HTTP Web 服务器。有什么可能的方法可以在其上使用/安装 Php 吗？我在谷歌上搜索了这个，但找不到任何帮助.....感谢任何帮助！

到目前为止我的代码：

package minet;

import java.util.*;
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.*;
import java.net.*;

public class main {
    private static ServerSocket serverSocket;

    public static void main(String[] args) throws IOException {
        JFrame ip = new JFrame();
        JTextField field = new JTextField();
        field.setText("http://" + getIP() + ":8080");
        field.setEditable(false);
        field.setBounds(10, 10, 380, 110);
        ip.add(field);
        JButton shutdown = new JButton("Shutdown Minet");
        shutdown.setBounds(30, 120, 340, 50);
        ip.add(shutdown);
        ip.setLocationRelativeTo(null);
        ip.setSize(400, 200);
        ip.setLayout(null);
        ip.setVisible(true);
        shutdown.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                System.out.println("Shutting down Minet...");
                field.setText("Shutting down Minet...");
                setTimeout(() -> System.exit(0), 1000);
            }
        });

        serverSocket = new ServerSocket(8080); // Start, listen on port 8080
        while (true) {
            try {
                Socket s = serverSocket.accept(); // Wait for a client to connect
                new ClientHandler(s); // Handle the client in a separate thread
            } catch (Exception x) {

            }
        }).start();
    }

Answer 1

我无法确定您面临的确切问题。但是，根据问题，您似乎希望在 JAVA 服务器旁边安装 PHP 服务器。

这很容易做到，只需在安装 PHP 时选择不同的端口号。默认情况下，任何 PHP 服务器都选择端口 80，因此这本身就解决了您的问题。只需安装任何PHP服务器，可以通过http://localhost访问，而您的java服务器可以通过http://localhost:8080访问。

here 也有类似的讨论。请检查一下。

Answer 2

根据您的问题，我了解到您曾经使用 PHP 作为 Web 编程语言。并且您想用 Java 制作一个显示 PHP Web Server 的一些页面的应用程序。

为此，我认为您需要在您的应用程序中包含Built-in web server。你只需要download it，在你的应用程序路径或任何你想要的地方解压缩它。您可以在目录中找到 INSTALL 文件。如图所示安装它，然后通过以下方式启动 Web 服务器：

$ cd path/to/built-in/php/web/server
$ php -S localhost:8000

执行 cmd 命令显示在this post 中。您可以根据需要更改端口号。

另一个变体是您需要在应用程序安装包中包含压缩的 Apache 和 PHP，然后将其解压缩，并以编程方式编辑配置文件，然后将您的应用程序安装到某台计算机上。

要显示来自 PHP Web 服务器的页面，您只需使用 WebView。 here 显示了如何在 Swing 中使用它的示例，或者您可以根据需要直接使用 JavaFX 而无需 Swing，因为 WebView 是 JavaFX 的一部分。
