java - 无法打开流：使用 phpjavabridge 的 HTTP 请求失败

问题描述

我在使用 php java bridge 时遇到问题，出现这样的错误

Warning: require_once(http://localhost:8080/JavaBridge/java/Java.inc): failed to open stream: HTTP request failed! in /Library/WebServer/Documents/test2.php on line 3

Fatal error: require_once(): Failed opening required 'http://localhost:8080/JavaBridge/java/Java.inc' (include_path='.:') in /Library/WebServer/Documents/test2.php on line 3

我的 tomcat 已在 8080 端口运行。我强制使用 8080 端口，但仍然出现错误

这是我的 Java 桥的独立类

在此源代码中，我使用此代码强制手动选择 8080

/*   final int tcpSocket = Integer.parseInt(tcpSocketName);
                    final int freeJavaPort = findFreePort(tcpSocket);
                    final int freeHttpPort = findFreePort(8080);
                    final int freeHttpsPort = findFreePort(8443);
                    final Object result = JOptionPane.showInputDialog(null, "Start a socket listener on port", "Starting the PHP/Java Bridge ...", 3, null, new String[] { "INET_LOCAL:" + freeJavaPort, "INET:" + freeJavaPort, "HTTP_LOCAL:" + freeHttpPort, "HTTP:" + freeHttpPort, "HTTPS_LOCAL:" + freeHttpsPort, "HTTPS:" + freeHttpsPort }, "HTTP_LOCAL:" + freeHttpPort);
                        //final Object result = 8080;
                    if (result == null) {
                        System.exit(0);
                    }*/
                    //sockname = result.toString();
                    sockname = "8080";
                }

在 tcpServer 我强制选择该端口使用此代码

import java.net.Socket;
import java.net.UnknownHostException;
import java.net.InetAddress;
import java.io.IOException;
import java.net.ServerSocket;

public class TCPServerSocket implements ISocketFactory
{
    public static int TCP_PORT_BASE;
    private ServerSocket sock;
    private int port;
    boolean local;
    
    public static ISocketFactory create(String name, final int backlog) throws IOException {
        boolean local = false;
        if (name == null) {
            throw new NullPointerException("name");
        }
        if (name.startsWith("INET:")) {
            name = name.substring(5);
        }
        else if (name.startsWith("INET_LOCAL:")) {
            local = true;
            name = name.substring(11);
        }
        final int p = Integer.parseInt(name);
        final TCPServerSocket s = new TCPServerSocket(p, backlog, local);
        return s;
    }
    
    private ServerSocket newServerSocket(final int port, final int backlog) throws IOException {
        try {
            if (this.local) {
                return new ServerSocket(port, backlog, InetAddress.getByName("127.0.0.1"));
            }
        }
        catch (UnknownHostException ex) {}
        return new ServerSocket(port, backlog);
    }
    
    private void findFreePort(final int start, final int backlog) {
        int port = start;
        while (port < start + 100) {
            try {
                this.sock = this.newServerSocket(port, backlog);
                this.port = port;
                return;
            }
            catch (IOException e) {
                ++port;
                continue;
            }
        }
    }
    
    private TCPServerSocket(final int port, final int backlog, final boolean local) throws IOException {
        this.local = local;
        if (port == 0) {
            this.findFreePort(TCPServerSocket.TCP_PORT_BASE, backlog);
        }
        else {
            this.sock = this.newServerSocket(port, backlog);
            this.port = port;
        }
    }
    
    @Override
    public void close() throws IOException {
        this.sock.close();
    }
    
    @Override
    public Socket accept() throws IOException {
        final Socket s = this.sock.accept();
        s.setTcpNoDelay(true);
        return s;
    }
    
    @Override
    public String getSocketName() {
        return String.valueOf(this.port);
    }
    
    @Override
    public String toString() {
        return (this.local ? "INET_LOCAL:" : "INET:") + this.getSocketName();
    }
    
    static {
     //   TCPServerSocket.TCP_PORT_BASE = 9267;
        TCPServerSocket.TCP_PORT_BASE = 8080;
    }
}

但是我的 javabridge 无法在该端口打开流，为什么这样？任何想法只选择端口 8080 不选择其他？

解决方案

我更改此代码后此问题关闭

try { /*
                  final int tcpSocket = Integer.parseInt(tcpSocketName);
                    final int freeJavaPort = findFreePort(tcpSocket);
                    final int freeHttpPort = findFreePort(8080);
                    final int freeHttpsPort = findFreePort(8443);
                    final Object result = JOptionPane.showInputDialog(null, "Start a socket listener on port", "Starting the PHP/Java Bridge ...", 3, null, new String[] { "INET_LOCAL:" + freeJavaPort, "INET:" + freeJavaPort, "HTTP_LOCAL:" + freeHttpPort, "HTTP:" + freeHttpPort, "HTTPS_LOCAL:" + freeHttpsPort, "HTTPS:" + freeHttpsPort }, "HTTP_LOCAL:" + freeHttpPort);
                        //final Object result = 8080;
                    if (result == null) {
                        System.exit(0);
                    }*/
                    //sockname = result.toString();
                    
                    sockname = "HTTP_LOCAL:8080";
                    System.out.println("sockname"+sockname);
                }

所以 sockname 使用“HTTP_LOCAL:8080”而不是“8080”
