Android 身份验证 wampserver

Question

我正在尝试进行 android 登录 activity，我创建了一个简单的数据库，其中包含一个 table 来测试我的登录 activity。我的问题是，当我输入正确的用户名和密码时，它告诉我用户名和密码错误，我在论坛中搜索过是否有人遇到了与我类似的问题，但我找不到。我真的被这个问题困了一个多月了..如果有人能帮我解决这个问题，我将不胜感激。

这是我的Login.javaclass

public class Login extends Activity implements OnClickListener {
private EditText _myLogin;
private EditText _myPassword;
private String _myContenuLogin;
private String _myContenuPassword;
private boolean _myCheck;
private ProgressDialog _myDialog;

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

    Button lBtnValidate = (Button) findViewById(R.id.authen_btn_valider);
    lBtnValidate.setOnClickListener(this);
    Button lBtnCancel = (Button) findViewById(R.id.authen_btn_annuler);
    lBtnCancel.setOnClickListener(this);

    _myLogin = (EditText) findViewById(R.id.authen_editlogin);
    _myPassword = (EditText) findViewById(R.id.authen_editlmdp);

}


@Override
public void onClick(View v) {

    if (v.getId() == R.id.authen_btn_valider) {
        _myContenuLogin = _myLogin.getText().toString();
        _myContenuPassword = _myPassword.getText().toString();



        MyAsyncTask myTask = new MyAsyncTask();
        myTask.execute(Stat.URL_CHECK);

        if (_myCheck) {
            Toast.makeText(this, "Bienvenue " + _myContenuLogin,
                    Toast.LENGTH_SHORT).show();
            Intent lIntentHome = new Intent(this, Home.class);
            startActivity(lIntentHome);
            this.finish();

        } else {
            Toast.makeText(this,
                    "Nom d'utilisateur ou mot de passe incorrecte",
                    Toast.LENGTH_LONG).show();

        }

    } else if(v.getId() == R.id.authen_btn_annuler){
        this.finish();
    }


}






private class MyAsyncTask extends AsyncTask<String, Void, Boolean>{

    @Override
    protected void onPreExecute() {
        _myDialog = ProgressDialog.show(Login.this, "Vérification", "Attendez SVP...");


    }

    @Override
    //String...params : Array of Strings , on a mis params[0] puisqu'on a une seule chaîne
    protected Boolean doInBackground(String... params) {

        ClientHTTP lClientHTTP=new ClientHTTP(Login.this);

        ArrayList<NameValuePair> list=new ArrayList<NameValuePair>();

        BasicNameValuePair lParamName=new BasicNameValuePair("PARAM_NAME", _myContenuLogin);
        list.add(lParamName);

        BasicNameValuePair lParamPassword=new BasicNameValuePair("PARAM_PASSWORD", _myContenuPassword);
        list.add(lParamPassword);

        _myCheck=lClientHTTP.SendToUrl(params[0], list);

        return _myCheck;
    }
    @Override
    protected void onPostExecute(Boolean result) {
        _myDialog.dismiss();
    }

}

}

这是我的 Stat.java class，其中包含有用的字符串

public class Stat {
public static final String DB_NAME = "leoni.db";
public static final String TABLE_NAME = "agent_sos";
public static final String COL_ID = "id";
public static final String COL_NOM_PRENOM = "nom_prenom";
public static final String COL_MDP = "mot_de_passe";
public static final String URL_CHECK = "http://127.0.0.1/check.php";

}

这是我的 ClientHTTP.java class，其中包含连接、获取和发送到 url

的方法

public class ClientHTTP {

private Context _mContext;

public ClientHTTP(Context pContext){
    _mContext=pContext;
}
//méthode pour lire le contenu d'un URL
public String readFromUrl(String strURL) {
    URL clientURL = null;
    HttpURLConnection client = null;
    // Créer un buffer , StringBuilder() permet de créer une chaîne de caractères modifiable
    StringBuilder builder = new StringBuilder();
    // Créer un client Http
    try {
        clientURL = new URL(strURL);
        client = (HttpURLConnection) clientURL.openConnection();
    } catch (MalformedURLException e1) {

        e1.printStackTrace();
    } catch (IOException e) {

        e.printStackTrace();
    }

    // Créer un obejet httpget pour utiliser la methode get
    HttpGet httpGet = new HttpGet(strURL);
    try {
        // récuperer la réponse
        HttpResponse response = ((HttpClient) client).execute(httpGet);
        //
        StatusLine statusLine = response.getStatusLine();
        // récuperer le ack
        int statusCode = statusLine.getStatusCode();
        // si ack =200 connexion avec succée
        if (statusCode == 200) {
            //récuperer l'entité
            HttpEntity entity = response.getEntity();
            //récuperer le contenu de l'entité , 
            InputStream content = entity.getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(content));
            String line;
            while ((line = reader.readLine()) != null) {
                builder.append(line);
            }
        } else {
            // errur du chargement
            Toast.makeText(_mContext, "pas de connexion", Toast.LENGTH_LONG).show();
        }
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return builder.toString();
}

public boolean SendToUrl(String strURL,ArrayList<NameValuePair> nameValuePairs) {
    // Créer un buffer
    StringBuilder builder = new StringBuilder();
    // Créer un client Http
    HttpClient client = new DefaultHttpClient();
    // Créer un obejet httppost pour utiliser la methode post
    HttpPost httppost = new HttpPost(strURL);
    try {
        //UrlEncodedFormEntit() : An entity composed of a list of url-encoded pairs
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        // récuperer la réponse
        HttpResponse response = client.execute(httppost);

        StatusLine statusLine = response.getStatusLine();
        // récuperer le ack
        int statusCode = statusLine.getStatusCode();
        // si ack =200 connexion avec succée
        if (statusCode == 200) {

            HttpEntity entity = response.getEntity();
            InputStream content = entity.getContent();
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(content));
            String line;
            while ((line = reader.readLine()) != null) {
                builder.append(line);
            }
        } else {
            // erreur du chargement
            Toast.makeText(_mContext, "pas de connexion", Toast.LENGTH_LONG).show();
        }
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return Boolean.parseBoolean(builder.toString());
}
}

最后这是我的 check.php 文件

<?php
/*mysql_real_escape_string Protège une commande SQL de la présence des caractères spéciaux */
$username = mysql_real_escape_string($_REQUEST['PARAM_NAME']);
$password = mysql_real_escape_string($_REQUEST['PARAM_PASSWORD']);

  mysql_connect("localhost","root","");
  mysql_select_db("leoni");

$result=mysql_query("SELECT nom_prenom,mot_de_passe FROM agent_sos WHERE nom_prenom ='$username' AND mot_de_passe='$password'");
if (mysql_num_rows($result) == 0) {
   echo "false"; 
} else {
   echo "true";
}

?>

Answer 1

改变这个：

 public class Stat {
  public static final String DB_NAME = "leoni.db";
  public static final String TABLE_NAME = "agent_sos";
  public static final String COL_ID = "id";
  public static final String COL_NOM_PRENOM = "nom_prenom";
  public static final String COL_MDP = "mot_de_passe";
  public static final String URL_CHECK = "http://127.0.0.1/check.php";
 }

有了这个：

 public class Stat {
  public static final String DB_NAME = "leoni.db";
  public static final String TABLE_NAME = "agent_sos";
  public static final String COL_ID = "id";
  public static final String COL_NOM_PRENOM = "nom_prenom";
  public static final String COL_MDP = "mot_de_passe";
  public static final String URL_CHECK = "http://10.0.2.2/check.php"; //If you are using Emulator or your Computer Ip address by using cmd > ipconfig

 }

Answer 2

我的问题是我在 wampsever 2.5 上使用了旧版本的 mysql，所以这是一个兼容性问题，我通过更改我的 php 脚本来修复它：

<?php
$mysqli = new mysqli("localhost", "root", "", "leoni");

/* Vérification de la connexion */
if (mysqli_connect_errno()) {
    printf("Échec de la connexion : %s\n", mysqli_connect_error());
    exit();
}
/* Recuperer les params passées */
$username = $mysqli->real_escape_string($_POST['PARAM_NAME']);
$password = $mysqli->real_escape_string($_POST['PARAM_PASSWORD']);


 $result =  $mysqli->query("SELECT COUNT(*) FROM agent_sos WHERE nom_prenom ='$username' AND mot_de_passe='$password'");
 $row = $result->fetch_row();
 if($row[0] !=0) {
    printf("true");
}else
    printf("false");

/* Fermeture de la connexion */
$mysqli->close();
?>

我用这个改变了URL_CHECK：192.168.1.4这是命令[=15的结果=]ipconfig 我的新问题是它在模拟器上运行完美，但在设备上无法运行！这是为什么？
