我无法登录或注册我的应用程序

Question

我的应用有问题。当我想登录或注册时，class SocketHandler(tornado.websocket.WebSocketHandler): def get(self, *args, **kwargs): if self.get_current_user(): ... super(SocketHandler, self).get(*args, **kwargs) else: ... 将显示并永不取消。在应用程序运行期间，它必须取消并且必须显示“ok”消息。

这是我的代码：

主要

ProgressDialog

import java.util.TimerTask;
import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.Toast;

public class Main extends Activity {

private ImageView login,register;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);



    login=(ImageView) findViewById(R.id.main_login);
    register=(ImageView) findViewById(R.id.main_register);


    login.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent lo=new Intent(Main.this,login.class);
            startActivity(lo);

        }
    });



    register.setOnClickListener(new OnClickListener() {
        public void onClick(View arg0) {

            Intent lo=new Intent(Main.this,register.class);
            startActivity(lo);

Answer 1

有两个错误。

1. 在loginserver.java中，变量赋值在构造函数
中相反

您的代码是

   public loginserver(String link,String user,String pass){

        link=Link;
        user=User;
        pass=Pass;

    }

应该是

    public loginserver(String link, String user, String pass) {

    Link = link;
    User = user;
    Pass = pass;

    } 

1. 这是您的login.java
中的拼写错误

在您的代码中

    new loginserver("http://ujo.ir/login,php",user,pass).execute();

它的login.php没有登录，php

我更改了这两个并使用用户ID和密码登录。 我得到了祝酒词＆＃34; ok＆＃34;

如果您正在建立http连接，那么使用它会很好 HttpURLConnection而不是URLconnection，因为它提供额外的API来处理http连接。我附上了loginserver.java的代码

     protected String doInBackground(Object... arg0) {

        try {

            String data=URLEncoder.encode("username","UTF8")+"="+URLEncoder.encode(User,"UTF8");
            data+="&"+URLEncoder.encode("password","UTF8")+"="+URLEncoder.encode(Pass,"UTF8");
            Log.i("loginserver","loginserver is called"+data);//helped to find the error 1

            URL mylink=new URL(Link);
            HttpURLConnection connect=(HttpURLConnection) mylink.openConnection();
            connect.setDoOutput(true);
            connect.setChunkedStreamingMode(0);

            OutputStreamWriter wr=new OutputStreamWriter(connect.getOutputStream());
            wr.write(data);
            wr.flush();
            Log.i("loginserver","after flush"+connect.getResponseCode());//helped to find the error 2
            BufferedReader reader=new BufferedReader(new InputStreamReader(connect.getInputStream()));
            StringBuilder sb=new StringBuilder();
            String line=null;
            while((line=reader.readLine()) != null){
                Log.i("loginserver","we enter while");
            sb.append(line);    

            }

            login.res=sb.toString();
            Log.i("loginserver","value is" + login.res);


        } catch (Exception e) {


        }


        return "";
    }
