我正在進行註冊和登錄活動。 當我輸入名稱,用戶名和密碼時,訪問android應用程序的信息。 和Toast顯示'註冊成功'消息。 但數據沒有插入到mysql數據庫中。 我該如何解決它?請幫幫我。將android數據插入到mysql中
以下是LoginActivity.java
public class LoginActivity extends Activity {
EditText ET_NAME,ET_PASS;
String login_name,login_pass;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login_main);
ET_NAME = (EditText)findViewById(R.id.user_name);
ET_PASS = (EditText)findViewById(R.id.user_pass);
}
public void userReg(View view)
{
startActivity(new Intent(this,RegisterActivity.class));
}
public void userLogin(View view)
{
login_name = ET_NAME.getText().toString();
login_pass = ET_PASS.getText().toString();
String method = "login";
BackgroundTask backgroundTask = new BackgroundTask(this);
backgroundTask.execute(method,login_name,login_pass);
Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("ID", login_name);
intent.putExtra("PW", login_pass);
startActivity(intent);
finish();
}
}
這是BackgroundTask.java
public class BackgroundTask extends AsyncTask<String,Void,String> {
AlertDialog alertDialog;
Context ctx;
BackgroundTask(Context ctx) {
this.ctx = ctx;
}
@Override
protected void onPreExecute() {
alertDialog = new AlertDialog.Builder(ctx).create();
}
@Override
protected String doInBackground(String... params) {
String reg_url = "http://35.160.135.119/webapp/register.php";
String login_url = "http://35.160.135.119/webapp/login.php";
String method = params[0];
if (method.equals("register")) {
String name = params[1];
String user_name = params[2];
String user_pass = params[3];
try {
URL url = new URL(reg_url)
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setDoOutput(true);
//httpURLConnection.setDoInput(true);
OutputStream OS = httpURLConnection.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(OS, "UTF-8"));
String data = URLEncoder.encode("name", "UTF-8") + "=" + URLEncoder.encode(name, "UTF-8") + "&" +
URLEncoder.encode("user_name", "UTF-8") + "=" + URLEncoder.encode(user_name, "UTF-8") + "&" +
URLEncoder.encode("user_pass", "UTF-8") + "=" + URLEncoder.encode(user_pass, "UTF-8");
bufferedWriter.write(data);
bufferedWriter.flush();
bufferedWriter.close();
OS.close();
InputStream IS = httpURLConnection.getInputStream();
IS.close();
//httpURLConnection.connect();
httpURLConnection.disconnect();
return "Registration Success...";
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} else if (method.equals("login")) {
String login_name = params[1];
String login_pass = params[2];
try {
URL url = new URL(login_url);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setDoOutput(true);
httpURLConnection.setDoInput(true);
OutputStream outputStream = httpURLConnection.getOutputStream();
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
String data = URLEncoder.encode("login_name", "UTF-8") + "=" + URLEncoder.encode(login_name, "UTF-8") + "&" +
URLEncoder.encode("login_pass", "UTF-8") + "=" + URLEncoder.encode(login_pass, "UTF-8");
bufferedWriter.write(data);
bufferedWriter.flush();
bufferedWriter.close();
outputStream.close();
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "iso-8859-1"));
String response = "";
String line = "";
while ((line = bufferedReader.readLine()) != null) {
response += line;
}
bufferedReader.close();
inputStream.close();
httpURLConnection.disconnect();
return response;
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
}
@Override
protected void onProgressUpdate(Void... values) {
super.onProgressUpdate(values);
}
@Override
protected void onPostExecute(String result) {
if (result.equals("Registration Success...")) {
Toast.makeText(ctx, result, Toast.LENGTH_LONG).show();
} else {
alertDialog.setMessage(result);
alertDialog.show();
}
}
}
這是Register.java
public class RegisterActivity extends Activity {
EditText ET_NAME, ET_USER_NAME, ET_USER_PASS;
String name, user_name, user_pass;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.register_layout);
ET_NAME = (EditText)findViewById(R.id.name);
ET_USER_NAME = (EditText)findViewById(R.id.new_user_name);
ET_USER_PASS = (EditText)findViewById(R.id.new_user_pass);
}
public void userReg(View view)
{
name = ET_NAME.getText().toString();
user_name = ET_USER_NAME.getText().toString();
user_pass = ET_USER_PASS.getText().toString();
String method = "register";
BackgroundTask backgroundTask = new BackgroundTask(this);
backgroundTask.execute(method,name, user_name, user_pass);
finish();
}
}
這是調試日誌。

謝謝。我檢查了我的錯誤日誌並修復了php代碼。它現在有效。 但我不明白你的第一個建議。放完();代碼到後執行觸發器錯誤.. –
這是一個很好的做法.. cuz on post當您的異步任務完成其執行時調用執行... –
