Question

我正在尝试使用SOCKETS建立客户端/服务器连接。

服务器端是Eclipse中的Java，客户端在Android Studio中。

服务器端和客户端都有一些代码用于套接字连接。

昨天连接成功了。今天，我尝试用android app客户端连接到服务器，我有FAİLED。

当我检查来自 netstat -a -n 的连接时，我看到了：

（当我打开客户端时）

这很奇怪，因为在连接代码工作之前我已经看过这个端口了。端口增加了。

和服务器代码：

public class CapitalizeServer {

static  ArrayList<Client> clients = new ArrayList<>();

public static void main(String[] args) throws Exception {
    System.out.println("The capitalization server is running.");

    int clientNumber = 0;
    ServerSocket listener = new ServerSocket(44057);
    try {
        while (true) {
            new Capitalizer(listener.accept(), clientNumber++).start();
        }
    } finally {
        listener.close();
    }
}

        log("New connection with client# " + clientNumber + " at " + socket);
    }

客户第一个活动代码：

public class SignInMenu extends ActionBarActivity {

Button button18;
EditText et1,et2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.signin_menu);
    button18 = (Button) findViewById(R.id.button18);
    et1 = (EditText) findViewById(R.id.editText);
    et2 = (EditText) findViewById(R.id.editText2);
}

public void button18Click(View view){
    Intent intent = new Intent(this, MainActivity.class);
    intent.putExtra("uname",et1.getText().toString());
    intent.putExtra("pass",et2.getText().toString());
    startActivity(intent);
}

 }

我正在使用WAMP服务器。它有一些奇怪的东西。我无法使用我的本地IP（192.168.1.36）访问localhost。只有这样：http://localhost/

当我尝试连接我的本地IP时，错误如下：192.168.1.36拒绝连接。

也许这就是问题所在。

那么我该如何解决这个问题？

EDİT:(新问题）

*问题是关于java-php连接现在。

我的服务器连接到php查询。这是连接到php页面的代码。我在“PrintStream ps = new PrintStream（con.getOutputStream（））;”中出错。错误说：连接被拒绝：连接

try{
            // open a connection to the site
            URL url = new URL("http://192.168.1.35/userControls/singin.php");
            URLConnection con = url.openConnection();
            // activate the output
            con.setDoOutput(true);
            //con.setDoInput(true);
            PrintStream ps = new PrintStream(con.getOutputStream());
            // send your parameters to your site
            ps.print(URLEncoder.encode("uname","UTF-8") + "=" + URLEncoder.encode(uname, "UTF-8"));
            ps.print(URLEncoder.encode("&pass=","UTF-8")+ "=" + URLEncoder.encode(pass, "utf-8"));

            ps.close();
            BufferedReader cin = new BufferedReader(new InputStreamReader(con.getInputStream()));
            String line = null;
            while ((line = cin.readLine()) != null) {
                System.out.println(":::::::Worked:::::::::   " + line);
            }
           }/* catch (MalformedURLException e) {
                e.printStackTrace();
           } catch (IOException e) {
                e.printStackTrace();
           }*/ catch (Exception e) {
                System.out.println("Eror:" + e.getMessage());
        }

我如何解决第二个问题？
