Android设备搭建http服务---------AndServer

项目中引用AndServer

implementation 'com.yanzhenjie.andserver:api:2.1.10'

在项目的根build.gradle文件（不是app那个moudle的build.gradle）最顶部添加：

buildscript {    repositories {        MavenCentral()    }     dependencies {        classpath 'com.yanzhenjie.andserver:plugin:2.1.10'    }}

在当前的moudle(一般就是app)的build.gradle里面的plugins里面添加：

id 'com.yanzhenjie.andserver'

plugins

plugins {    id 'com.Android.application'    id 'com.yanzhenjie.andserver'}

build.gradle里面dependencies的添加

    implementation 'com.yanzhenjie.andserver:api:2.1.10'    annotationProcessor 'com.yanzhenjie.andserver:processor:2.1.10'

代码

package com.dzdpencrypt.dzdp; import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; import com.yanzhenjie.andserver.AndServer;import com.yanzhenjie.andserver.Server; import java.util.concurrent.TimeUnit; public class MainActivity extends AppCompatActivity {    private Server mServer;     @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        if (!isServiceRunning(getApplicationContext(), KeepAliveService.class)) {            Log.d(LOG_TAG, "检测到服务未在运行,启动服务");            serviceIntent = new Intent(this, KeepAliveService.class);            startService(serviceIntent);        } else {            Log.d(LOG_TAG, "检测到服务正在运行,无需再次启动");        }                TextView textView = findViewById(R.id.ipsd);   # 绑定textview的相关id        textView.setText(NetUtils.getLocalIPAddress().getHostAddress() + ":9999");   # app中textview显示ip+端口        mServer = AndServer.WEBServer(this)                .port(9999)                .timeout(10, TimeUnit.SECONDS).listener(new Server.ServerListener() {                    @Override                    public void onStarted() {                        System.out.println("服务器绑定地址:"+NetUtils.getLocalIPAddress().getHostAddress());                    }                    @Override                    public void onStopped() {                    }                    @Override                    public void onException(Exception e) {                    }                })                .build();        mServer.startup();    }     @Override    protected void onDestroy() {        super.onDestroy();        mServer.shutdown();    }}

以上代码启动在Android手机（设备）上的Http服务器，服务器绑定端口9999

spring样式的restful代码实现

package com.dzdpencrypt.service; import com.yanzhenjie.andserver.annotation.GetMapping;import com.yanzhenjie.andserver.annotation.PathVariable;import com.yanzhenjie.andserver.annotation.PostMapping;import com.yanzhenjie.andserver.annotation.QueryParam;import com.yanzhenjie.andserver.annotation.RequestBody;import com.yanzhenjie.andserver.annotation.RequestParam;import com.yanzhenjie.andserver.annotation.RestController; import org.JSON.jsONObject;  @RestControllerpublic class ServerController {    @GetMapping("/")    public String ping() {        return "SERVER OK";    }     @PostMapping("/user/login")    public JSONObject login(@RequestBody String str) throws Exception {        JSONObject jsonObject = new JSONObject(str);        return jsonObject;    }     @GetMapping("/user/item")    public JSONObject requestItem(@RequestParam("name") String name,     @RequestParam("id") String id) throws Exception {        JSONObject jsonObject = new JSONObject();        jsonObject.put("name", name);        jsonObject.put("id", id);         return jsonObject;    }     @GetMapping("/user/{userId}")    public JSONObject getUser(@PathVariable("userId") String userId,                           @QueryParam("key") String key) throws Exception{        JSONObject user = new JSONObject();        user.put("id", userId);        user.put("key", key);        user.put("year", 2022);         return user;    }}

NetUtils.java-------获取当前Android手机的IP地址

package com.dzdpencrypt.service; import java.net.InetAddress;import java.net.NetworkInterface;import java.net.SocketException;import java.util.Enumeration;import java.util.regex.Pattern; public class NetUtils {    private static final Pattern IPV4_PATTERN = Pattern.compile(            "^(" + "([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\\.){3}" +                    "([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$");     public static boolean isIPv4Address(String input) {        return IPV4_PATTERN.matcher(input).matches();    }     public static InetAddress getLocalIPAddress() {        Enumeration<NetworkInterface> enumeration = null;        try {            enumeration = NetworkInterface.getNetworkInterfaces();        } catch (SocketException e) {            e.printStackTrace();        }        if (enumeration != null) {            while (enumeration.hasMoreElements()) {                NetworkInterface nif = enumeration.nextElement();                Enumeration<InetAddress> inetAddresses = nif.getInetAddresses();                if (inetAddresses != null) {                    while (inetAddresses.hasMoreElements()) {                        InetAddress inetAddress = inetAddresses.nextElement();                        if (!inetAddress.isLoopbackAddress() && isIPv4Address(inetAddress.getHostAddress())) {return inetAddress;                        }                    }                }            }        }        return null;    }}

AndroidManifest.xml配置网络权限

    <uses-permission android:name="android.permission.INTERNET"/>    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
