6편까지 길게 있어서 코드를 기록하려고 쓴다. AWS에서 작업하며 php, MySQL을 사용한다.

 

먼저 DB 설정이다. DB 이름은 users고 테이블 이름은 users_table이다.

 

 

다음은 php 파일이다. 대략적인 파일명은 주석식으로 써뒀다.

 

// volley_connect.php

<?php

$conn = mysqli_connect("11.111.111.11", "root", "비밀번호", "users");

// login.php

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
    $email = $_POST['email'];
    $password = $_POST['password'];

    require_once 'volley_connect.php';

    $sql = "SELECT * FROM users_table WHERE email = '$email'";

    $response = mysqli_query($conn, $sql);

    $result = array();
    $result['login'] = array();

    if (mysqli_num_rows($response) === 1)
    {
        $row = mysqli_fetch_assoc($response);
        if (password_verify($password, $row['password']))
        {
            $index['name'] = $row['name'];
            $index['email'] = $row['email'];
            $index['id'] = $row['id'];

            array_push($result['login'], $index);

            $result['success'] = "1";
            $result['message'] = "success";
            echo json_encode($result);

            mysqli_close($conn);
        }
        else
        {
            $result['success'] = "0";
            $result['message'] = "error";
            echo json_encode($result);

            mysqli_close($conn);
        }
    }
}

// edit_detail.php

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
    $name = $_POST['name'];
    $email = $_POST['email'];
    $id = $_POST['id'];

    require_once 'volley_connect.php';

    $sql = "UPDATE users_table SET name = '$name', email = '$email' WHERE id = '$id'";

    if (mysqli_query($conn, $sql))
    {
        $result['success'] = "1";
        $result['message'] = "사용자 정보 수정 완료";

        echo json_encode($result);
        mysqli_close($conn);
    }
}
else
{
    $result['success'] = "0";
    $result['message'] = "사용자 정보 수정 실패";
    echo json_encode($result);

    mysqli_close($conn);
}

// read_detail.php

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
    $id = $_POST['id'];

    require_once 'volley_connect.php';

    $sql = "SELECT * FROM users_table WHERE id = '$id'";

    $response = mysqli_query($conn, $sql);

    $result = array();
    $result['read'] = array();

    if (mysqli_num_rows($response) === 1)
    {
        if ($row = mysqli_fetch_assoc($response))
        {
            $h['name'] = $row['name'];
            $h['email'] = $row['email'];

            array_push($result['read'], $h);

            $result['success'] = "1";
            echo json_encode($result);
        }
    }
}
else
{
    $result['success'] = "0";
    $result['message'] = "error";
    echo json_encode($result);

    mysqli_close($conn);
}

// register.php

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
    $name = $_POST['name'];
    $email = $_POST['email'];
    $password = $_POST['password'];

    $password = password_hash($password, PASSWORD_DEFAULT);

    require_once 'volley_connect.php';

    $sql = "INSERT INTO users_table(name, email, password) VALUES ('$name', '$email', '$password')";

    if (mysqli_query($conn, $sql))
    {
        $result["success"] = "1";
        $result["message"] = "success";

        echo json_encode($result);
        mysqli_close($conn);
    }
    else
    {
        $result["success"] = "0";
        $result["message"] = "error";

        echo json_encode($result);
        mysqli_close($conn);
    }
}

// upload.php

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
    $id = $_POST['id'];
    $photo = $_POST['photo'];

    $path = "uploads/$id.jpeg";
    $finalPath = "http://11.111.111.11/" . $path;

    require_once 'volley_connect.php';

    $sql = "UPDATE users_table SET photo = '$finalPath' WHERE id = '$id'";

    if (mysqli_query($conn, $sql))
    {
        if (file_put_contents($path, base64_decode($photo)))
        {
            $result['success'] = "1";
            $result['message'] = "success";

            echo json_encode($result);
            mysqli_close($conn);
        }
    }
}

 

다음은 안드로이드 코드다. 먼저 매니페스트에 인터넷 권한을 줘야 한다.

<uses-permission android:name="android.permission.INTERNET" />

 

그리고 application 태그 안에 두 속성을 넣어야 한다.

 

android:networkSecurityConfig="@xml/network_security_config"
android:usesCleartextTraffic="true"

 

android:networkSecurityConfig 속성을 건드리려면 res 폴더 안에 xml 폴더를 만들고 network_security_config이란 이름의 xml 파일을 하나 만들어야 한다. 이 파일의 내용은 아래와 같이 한다.

 

<?xml version="1.0" encoding="utf-8"?>
<network-security-config xmlns:tools="http://schemas.android.com/tools">
    <base-config cleartextTrafficPermitted="true"
        tools:ignore="InsecureBaseConfiguration" />
</network-security-config>

 

아래는 매니페스트의 최종 형태다. 이런 형태로 만들어지면 된다.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.volley">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppThemeRegist"
        android:networkSecurityConfig="@xml/network_security_config"
        android:usesCleartextTraffic="true">
        <activity android:name=".HomeActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".LoginActivity"/>
        <activity android:name=".MainActivity"/>
    </application>

</manifest>

 

그리고 메뉴가 사용되기 때문에, 마찬가지로 res 폴더 안에 menu 폴더를 만들고 menu_action.xml 파일을 하나 만들어준다.

icon 속성에 edit, save가 있는데 대충 수정이랑 저장에 맞는 이미지를 넣어주면 된다.

 

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item android:id="@+id/menu_edit"
        android:title="Edit"
        android:icon="@drawable/edit"
        app:showAsAction="always"/>

    <item android:id="@+id/menu_save"
        android:title="save"
        android:icon="@drawable/save"
        app:showAsAction="always"/>
</menu>

 

다음은 앱 수준 gradle 파일에 추가하는 의존성이다. 딱 3개만 입력한다.

3번째 것은 이미지뷰를 원 모양으로 나오게 하는 의존성이다.

 

implementation 'com.android.volley:volley:1.1.1'
implementation 'com.google.android.material:material:1.1.0'
implementation 'de.hdodenhof:circleimageview:2.2.0'

 

다음은 액티비티 클래스 파일을 제외한 클래스 파일이다. SessionManager.java 파일을 만들고 아래 내용을 복붙한다.

쉐어드 프리퍼런스를 활용해 로그인 세션을 유지할 수 있도록 하는 클래스다.

영상 만든 분은 PRIVATE_MODE = 0이라는 변수를 만드셨는데 그냥 쉐어드 이름 뒤에 0 넣으면 되는 걸 왜 굳이 변수로 만들어 쓰는지 지금도 이해가 안 간다. 개취인걸로 이해하려고 한다.

 

import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;

import java.util.HashMap;

public class SessionManager {

    SharedPreferences sharedPreferences;
    public SharedPreferences.Editor editor;
    public Context context;
    int PRIVATE_MODE = 0;

    private static final String PREF_NAME = "LOGIN";
    private static final String LOGIN = "IS_LOGIN";
    public static final String NAME = "NAME";
    public static final String EMAIL = "EMAIL";
    public static final String ID = "ID";

    public SessionManager(Context context)
    {
        this.context = context;
        sharedPreferences = context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
        editor = sharedPreferences.edit();
    }

    public void createSession(String name, String email, String id)
    {
        editor.putBoolean(LOGIN, true);
        editor.putString(NAME, name);
        editor.putString(EMAIL, email);
        editor.putString(ID, id);
        editor.apply();
    }

    public boolean isLoggin()
    {
        return sharedPreferences.getBoolean(LOGIN, false);
    }

    public void checkLogin()
    {
        if (!this.isLoggin())
        {
            Intent i = new Intent(context, LoginActivity.class);
            context.startActivity(i);
            ((HomeActivity) context).finish();
        }
    }

    public HashMap<String, String> getUserDetail()
    {
        HashMap<String, String> user = new HashMap<>();
        user.put(NAME, sharedPreferences.getString(NAME, null));
        user.put(EMAIL, sharedPreferences.getString(EMAIL, null));
        user.put(ID, sharedPreferences.getString(ID, null));

        return user;
    }

    public void logout()
    {
        editor.clear();
        editor.commit();
        Intent i = new Intent(context, LoginActivity.class);
        context.startActivity(i);
        ((HomeActivity) context).finish();
    }
}

 

다음은 액티비티 xml 파일이다. activity_main, activity_home, activity_login 순서다.
