Question

我目前正在Android下创建一个应用程序，可以让我连接用户。我使用常规的android服务器请求。我调用存储在我的服务器上的一个php文件，看看用户输入的是当前在BDD中注册的，但它根本不起作用...

这是我的php文件：

<?php

$con = mysqli_connect("localhost", "user", "userpass", "Android");

$username = $_POST["username"];
$password = $_POST["password"]

$statement = mysqli_prepare($con, "SELECT * FROM Utilisateur where username = ? AND password = ?");


mysqli_stmt_bind_param($statement, "ss", $username, $password); 
mysqli_stmt_execute($statement);

mysqli_stmt_store_result($statement);
mysqli_stmt_bind_result($statement, $userID, $name, $username, $mail, $password, $adresse, $ville, $zipCode);

$user = array();

while(mysqli_stmt_fetch($statement)){
  $user[name] = $name;
  $user[username] = $username;
  $user[mail] = $mail;
  $user[password] = $password;
  $user[adresse] = $adresse;
  $user[ville] = $ville;
  $user[zipCode] = $zipCode;
}

echo json_encode($user);

mysqli_stmt_close($statement);

mysqli_close($con);
 ?>

这是我在Java中的请求函数（有一个用户：密码，因为您需要进行身份验证才能访问我服务器上的任何网页）

public static final int CONNECTION_TIMEOUT = 1000 * 15;
public static final String SERVER_ADDRESS = "http://user:userpassword@62.210.193.223/Android/";

public class fetchUserDataAsyncTask extends AsyncTask<Void, Void, User> {
        User user;
        GetUserCallBack userCallBack;

        public fetchUserDataAsyncTask(User user, GetUserCallBack callBack) {
            this.user = user;
            this.userCallBack = callBack;
        }


        @Override
        protected User doInBackground(Void... params) {
            User returnedUser;

            try {

                URL url = new URL(SERVER_ADDRESS + "FetchUserData.php");
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setRequestMethod("POST");

                Uri.Builder builder = new Uri.Builder().appendQueryParameter("username", user.username)
                        .appendQueryParameter("password", user.password);

                String query = builder.build().getEncodedQuery();
                OutputStream os = conn.getOutputStream();
                BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
                writer.write(query);
                writer.flush();
                writer.close();
                os.close();
                conn.connect();

                InputStream in = new BufferedInputStream(conn.getInputStream());

                String response = IOUtils.toString(in, "UTF-8");
                JSONObject jResponse = new JSONObject(response);

                if (jResponse.length() == 0) {
                    returnedUser = null;
                } else {
                    String name = jResponse.getString("name");
                    String mail = jResponse.getString("mail");
                    String adresse = jResponse.getString("adresse");
                    String ville = jResponse.getString("ville");
                    int zipCode = jResponse.getInt("zipCode");

                    returnedUser = new User(name, user.name, user.password, mail, adresse, ville, zipCode);


                }
                return returnedUser;


            } catch (IOException | JSONException e) {
                e.printStackTrace();
            }


            return null;
        }


        @Override
        protected void onPostExecute(User returnedUser) {
            progressDialog.dismiss();
            userCallBack.done(returnedUser);
            super.onPostExecute(returnedUser);
        }

    }

我在调试模式下启动了我的应用程序，我抓住了这个例外：

java.io.FileNotFoundException: http://user:userpassword@62.210.193.223/Android/FetchUserData.php

我甚至尝试在网络浏览器中对网址进行C / C并执行该文件。当然它返回[]因为我在通话中没有包含POST。

我完全迷失了，因为android对我来说很新，而且我真的不知道在哪里寻找解决这个问题的方法......如果有人能帮助我解决这个问题，那将非常感激:)

干杯， ASTRUS

您似乎正在使用BasicAuth进行HTTP安全性。提供用户名和密码不是为您的请求提供基本凭据的好方法。

您需要设置正确的授权标头：

URLConnection uc = url.openConnection();
String userpass = username + ":" + password;
String basicAuth = "Basic " + new String(new Base64().encode(userpass.getBytes()));
uc.setRequestProperty ("Authorization", basicAuth);

请参阅：Connecting to remote URL which requires authentication using Java
