Question

我正在学习php for android，我正在尝试在数据库中插入注册数据。提交数据没有错误，但数据在数据库中不可见。主要活动： -

public class MainActivity extends AppCompatActivity {

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

public void userLogin(View view)
{

}

public void userReg(View view)
{
    startActivity(new Intent(this, Register.class));
}
}

Register.java

public class Register extends AppCompatActivity {

EditText etName, etUname, etUpass;
String name, uname, upass;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.register);
    etName = (EditText)findViewById(R.id.etName);
    etUname = (EditText)findViewById(R.id.etUname);
    etUpass = (EditText)findViewById(R.id.etUpass);


}
public void userReg(View view)
{
    name = etName.getText().toString();
    uname = etUname.getText().toString();
    upass = etUpass.getText().toString();

    String method = "register";
    BackgroundTask bt = new BackgroundTask(this);
    bt.execute(method,name,uname,upass);
    finish();
}
}

BackgroundTask.java

public class BackgroundTask extends AsyncTask <String, Void, String> {
Context ctx;

BackgroundTask(Context ctx)
{
    this.ctx = ctx;
}

@Override
protected void onPreExecute() {
    super.onPreExecute();
}

@Override
protected String doInBackground(String... params) {

    String regURL = "http://10.0.0.2/webapp/register.php";
    String logURL = "http://10.0.0.2/webapp/login.php";
    String method = params[0];
    if(method.equals("register"))
    {
        String name = params[1];
        String uname = params[2];
        String upass = params[3];
        try {
            URL reg_url = new URL(regURL);
            HttpURLConnection htc = (HttpURLConnection)reg_url.openConnection();
            htc.setRequestMethod("POST");
            htc.setDoOutput(true);
            OutputStream os = htc.getOutputStream();
            BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os,"UTF-8"));
            String data = URLEncoder.encode("user","UTF-8") + "=" +URLEncoder.encode(name,"UTF-8")+ "&" +
                    URLEncoder.encode("username","UTF-8") + "=" +URLEncoder.encode(uname,"UTF-8")+ "&" +
                    URLEncoder.encode("userpass","UTF-8") + "=" +URLEncoder.encode(upass,"UTF-8");
            bw.write(data);
            bw.flush();
            bw.close();
            os.close();
            InputStream is = htc.getInputStream();
            is.close();
            return "Registration Successful";
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }


    }
    return null;
}

@Override
protected void onProgressUpdate(Void... values) {
    super.onProgressUpdate(values);
}

protected void onPostExecute(String result) {
    Toast.makeText(ctx,result, Toast.LENGTH_LONG).show();
}
}

register.php

<?php

require 'db_connect.php';
$name = $_POST['user'];
$uname = $_POST['username'];
$upass = $_POST['userpass'];
$query = "INSERT INTO user_info (name,username,userpass) values('$name','$uname','$upass')";
$res = mysqli_query($conn,$query);
if($res)
{
    //echo "Done";
}
else
{
    //die(mysqli_error($conn));
}

?>

我点击按钮时最后会发出祝酒通知，但我甚至没有收到祝酒通知。日志中没有任何类型的错误。

我的android数据没有显示在php我的管理数据库中
