7.1 HTTP请求
在libGDX中，可以使用HttpRequest类来发送HTTP请求。以下是一个简单的示例：
package com.mygdx.game.http;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Net;
import com.badlogic.gdx.net.HttpRequestBuilder;
import com.badlogic.gdx.net.HttpStatus;
public class HttpExample {
public static void send() {
HttpRequestBuilder requestBuilder = new HttpRequestBuilder();
Net.HttpRequest httpRequest = requestBuilder.newRequest().method(Net.HttpMethods.GET).url("https://www.google.de").content("q=libgdx&example=example").build();
Gdx.net.sendHttpRequest(httpRequest, httpResponseListener);
//有参数的
// HttpRequestBuilder requestBuilder = new HttpRequestBuilder();
// HttpRequest httpRequest = requestBuilder.newRequest().method(HttpMethods.GET).url("https://www.google.de").content("q=libgdx&example=example").build();
// Gdx.net.sendHttpRequest(httpRequest, httpResponseListener);
}
private static final Net.HttpResponseListener httpResponseListener = new Net.HttpResponseListener() {
@Override
public void handleHttpResponse(Net.HttpResponse httpResponse) {
if (httpResponse.getStatus().getStatusCode() == HttpStatus.SC_OK) {
System.out.println("请求成功，响应内容：" + httpResponse.getResultAsString());
} else {
System.out.println("请求失败，状态码：" + httpResponse.getStatus().getStatusCode());
}
}
@Override
public void failed(Throwable throwable) {
System.out.println("失败");
}
@Override
public void cancelled() {
System.out.println("取消");
}
};
}
TCP通信，客户端
package com.mygdx.game.tcp;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Net;
import com.badlogic.gdx.net.Socket;
import com.badlogic.gdx.net.SocketHints;
import java.io.OutputStream;
public class Client extends Thread{
@Override
public void run() {
receivedTCP();
}
public void receivedTCP() {
// 创建客户端套接字
Socket socket = Gdx.net.newClientSocket(Net.Protocol.TCP, "localhost", 8080, null);
try {
// 获取输出流
OutputStream outputStream = socket.getOutputStream();
// 发送数据到服务器
outputStream.write("Hello, server!".getBytes());
outputStream.flush();
// 读取服务器响应
byte[] data = new byte[1024];
int length = socket.getInputStream().read(data);
String message = new String(data, 0, length);
System.out.println("Received from server: " + message);
} catch (Exception e) {
e.printStackTrace();
} finally {
// 关闭客户端套接字
socket.dispose();
}
}
}
TCP通信，服务端
package com.mygdx.game.tcp;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Net;
import com.badlogic.gdx.net.ServerSocket;
import com.badlogic.gdx.net.Socket;
import com.badlogic.gdx.net.SocketHints;
import java.io.OutputStream;
public class Server extends Thread {
@Override
public void run() {
openTcp();
}
public void openTcp() {
// 创建服务端套接字
ServerSocket serverSocket = Gdx.net.newServerSocket(Net.Protocol.TCP, 8080, null);
while (true) {
// 等待客户端连接
Socket socket = serverSocket.accept(null);
try {
// 获取输出流
OutputStream outputStream = socket.getOutputStream();
// 读取客户端发送的数据
byte[] data = new byte[1024];
int length = socket.getInputStream().read(data);
String message = new String(data, 0, length);
System.out.println("Received from client: " + message);
// 向客户端发送响应
outputStream.write("Hello, client!".getBytes());
outputStream.flush();
} catch (Exception e) {
e.printStackTrace();
} finally {
// 关闭客户端套接字
socket.dispose();
}
}
}
}
