最近因为学弟项目需求 要做实时通讯，想让我研究研究，我就帮忙写了写，怎么说呢，收获也是有的吧，然后打算把整个通讯给大家展示一遍，包括服务端和客户端，有兴趣的可以关注小编

先说整个项目的功能和过程
1.先实现两端交互
2.可以注册，登录用户
3.可以相互加好友
4.可以相互发文字
5.可以相互发送表情，语音等
本编博客主要来完成第一个内容：
一、先说Android端的实现：
1、注册页面
public class RegisterActivity extends AppCompatActivity {
private EditText et_register_user, et_register_pwd;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
inItUI();
}
//初始化UI
private void inItUI() {
et_register_user = (EditText) findViewById(R.id.et_register_user);
et_register_pwd = (EditText) findViewById(R.id.et_register_pwd);
}
//提交注册数据
public void click_Register_push(View view) {
String user = et_register_user.getText().toString();
String pwd = et_register_pwd.getText().toString();
//向服务器发送数据
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put(KeyValue.USER, user);
jsonObject.put(KeyValue.PWD, pwd);
register(jsonObject);
} catch (JSONException e) {
e.printStackTrace();
}
}
public void register (final JSONObject jsO){
RequestMethod.RequestLogin(this,jsO, new MyInterface.onRegisterCallback() {
@Override
public void Success(String role) {
}
@Override
public void Fail(String error) {
}
@Override
public void UnkownError(String unkownerror) {
}
});
}
}2、登录请求类：
public class RequestMethod {
//登录请求方法
public static void RequestLogin(final Activity activity, final JSONObject jsonObject,final MyInterface.onRegisterCallback onRegisterCallback){
new Thread(new Runnable() {
@Override
public void run() {
Looper.prepare();
JSONObject resultObject = ResponseMethod.sendRegister(jsonObject, UrlString.REGISTER);
Log.e("gaoyu", "返回结果是:" + resultObject.toString());
//解析登录结果
}
}).start();
}
}3、网络处理类：
public class ResponseMethod {
//服务端返回值方法
public static JSONObject sendRegister(JSONObject jo2, String url) {
InputStreamReader isr = null;
DataOutputStream dos = null;
HttpURLConnection urlConn = null;
BufferedReader bufferedReader = null;
JSONObject jsonObject = null;
try {
URL url1 = new URL(url);
urlConn = (HttpURLConnection) url1.openConnection();
urlConn.setDoInput(true);//设置输入流采用字节流
urlConn.setDoOutput(true);//设置输出流采用字节流
urlConn.setRequestMethod("POST");//post方法
urlConn.setUseCaches(false);//缓存
urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");//设置meta参数
urlConn.setRequestProperty("Charset", "utf-8");//缓存
urlConn.connect();//连接服务器发送消息
Log.e("gaoyu", "发送的信息是" + jo2.toString());
dos = new DataOutputStream(urlConn.getOutputStream());
dos.write((jo2.toString()).getBytes());//写数据
dos.close();
dos.flush();
isr = new InputStreamReader(urlConn.getInputStream());
bufferedReader = new BufferedReader(isr);
String result = "";
String readLine = null;
while ((readLine = bufferedReader.readLine()) != null) {
result += readLine;
}
Log.e("gaoyu", "返回的" + result);
result = removeBOM(result);
jsonObject = new JSONObject(result);
bufferedReader.close();
isr.close();
urlConn.disconnect();//关闭连接
return jsonObject;
} catch (MalformedURLException e) {
Log.e("gaoyu", "异常=MalformedURLException");
e.printStackTrace();
return jsonObject;
} catch (IOException e) {
Log.e("gaoyu", "异常=IOException");
e.printStackTrace();
return jsonObject;
} catch (JSONException e) {
Log.e("gaoyu", "异常=JSONException");
e.printStackTrace();
return jsonObject;
}
}
public static final String removeBOM(String data) {
if (TextUtils.isEmpty(data)) {
return data;
}
if (data.startsWith("\ufeff")) {
return data.substring(1);
} else {
return data;
}
}
}
二、再说服务端的实现（较简单）：
1、servlet的处理
@WebServlet("/RegisterServlet")
public class RegisterServlet extends HttpServlet {
public RegisterServlet() {
super();
}
public void destroy() {
super.destroy();
}
/**
* 处理get请求 request用于获得客户端信息 response用于向客户端返回信息
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// 可以将逻辑放在doPost里面
this.doPost(request, response);
}
/**
* 逻辑处理
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// 解决中文乱码
request.setCharacterEncoding("UTF-8");
//response.setCharacterEncoding("gbk");
response.setContentType("text/html;charset=UTF-8");
//response.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();
// 获取客户端数据
BufferedReader in = new BufferedReader(new InputStreamReader(
request.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
String result = "";
while ((line = in.readLine()) != null) {
sb.append(line);
}
result = sb.toString();
System.out.println("接受数据是" + result);
//开始返回数据
Map params = new HashMap();
params.put("status", "success");
JSONObject jsonObject = JSONObject.fromObject(params);
out.write(jsonObject.toString());
out.flush();
out.close();
}
public void init() throws ServletException {
// Put your code here
}
}最后我们来看一下实现效果：
android端
点击注册以后 服务端日志 ：
Android接受服务端返回值日志：
这样就实现的 android和服务端的交互！
小编会尽快更新以后功能，敬请期待！
