Laravel 5.7.17 發佈

2018.12.14 Laravel正式發佈了5.7.17的版本。主要是一些新的query builder方法以及偵測MariaDB連線失效的訊息還有改進Postgres增加foreign keys的改進。

新的query builder方法針對INSERT INTO SELECT增加了一個insertUsing的方法。然後呢在SQL HAVING二個值之間多了一個havingBetween。

對新的版本有興趣的朋友，可以參考Laravel上的changelog。

PHP管制檔案下載的方式

在許多時候，我們會不希望網友知道網址空間直接下載檔案，或是透過帳號密碼的管控才能下載時，該如何用程式做過濾及管制呢？

header("Content-type:application");
header("Content-Disposition: attachment; filename=file_name");
//file_name是預設下載時的檔名，可使用變數。
readfile("file");
//file是實際存放在你硬碟中要被下載的檔案，可使用變數。
exit(0);

header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="downloaded.pdf"');
readfile('original.pdf');
//限制下載速度，使用 while 迴圈加上 sleep。

while (!feof($handle)) {
echo fread($handle, 8192);
sleep(1);
}

$content = "";
$fp = fopen("http://file-to-download.com/a-file.zip", "rb");

if (!$fp)
die("Error opening file.");
while (!feof($fp))
$content .= fread($fp, 2048);
fclose($fp);

$fp=fopen("local-file-name.zip", "w");
fwrite($fp, $content);
fclose($fp);

$OrgFileName = mb_convert_encoding($OrgFileName, 'BIG-5','UTF-8');

$real_path = dirname(__FILE__).'/upload/'.$FileName;

header('Pragma: public');

header('Expires: 0');

header('Cache-Control: must-revalidate, post-check=0, pre-check=0');

header('Cache-Control: public', false);

header('Content-Description: File Transfer');

header('Accept-Ranges: bytes');

// application/force-download 為通用類型，亦可判斷檔案格式做改變

header('Content-Type: application/force-download');

header('Content-Length: '.filesize($real_path));

header('Content-Transfer-Encoding: binary');

// 注意「"」不可省略，否則FireFox會無法正確讀取

header('Content-Disposition:attachment;filename="'.$OrgFileName.'"');

// 讀取來源檔案資料

if ($stream = fopen($real_path, 'rb')){

while(!feof($stream) && connection_status() == 0){

echo(fread($stream,1024*8));

flush();

}

fclose($stream);

}

header('Content-type:application/force-download'); //告訴瀏覽器 為下載
header('Content-Transfer-Encoding: Binary'); //編碼方式
header('Content-Disposition:attachment;filename='.$filename); //檔名
@readfile($filename);

Windows Server 2016 安裝 PHP Laravel

一、開啟CGI功能
控制台→程式與功能→開啟或關閉Windows功能
開啟CGI

二、下載安裝PHP
http://windows.php.net/download/
三、修改php.ini
fastcgi.impersonate = 1
fastcgi.logging = 0
cgi.fix_pathinfo=1
cgi.force_redirect = 0
date.timezone = “Asia/Taipei”
extension_dir = “C:\PHP\ext”
四、安裝Visual C++ 可轉散發套件
五、IIS設定處理常式對應
六、IIS設定預設文件index.php
七、安裝URL Rewrite
https://www.iis.net/downloads/microsoft/url-rewrite

Laravel 5.4 + Vue.js 2 記事本範例


一、安裝Apache、MySQL、PHP環境

為了讓讀者能快速的撰寫程式，作者在Github上已經整理出一個適合開發Laravel的XAMPP環境。我們進到 https://github.com/superlevin/xamppforlaravel 點選 Clone or Download 後按 Download ZIP。

xamppforlaravel01

下載後，解壓縮到d:\xampp就可以運作了。執行 xampp-control 後，開啟相關服務即可。

xamppforlaravel02 xamppforlaravel03二、安裝 composer，到 https://getcomposer.org/download/ 下載Composer-Setup.exe。

xamppforlaravel04

 

安裝時，將PHP路徑指向D:\xampp\php.exe

xamppforlaravel05 xamppforlaravel06 xamppforlaravel07 xamppforlaravel08 xamppforlaravel09 xamppforlaravel10 xamppforlaravel11 xamppforlaravel12 xamppforlaravel13 xamppforlaravel14

 

三、進入終端機模式(開始→執行  cmd)，然後設定php到系統變數

set PATH=%PATH%;d:\xampp\php

四、phpmyadmin建立資料庫

進入 http://localhost:8899/phpmyadmin 網頁

建立新資料庫 laravelvuenotes

五、透過composer 建立 laravel專案

dos指定切換 d:\xampp\htdocs\ 輸入

composer create-project laravel/laravel laravelvuenote

六、建立完成後，進入laravel專案修改.env設定

八、刪除migration中其他沒用的檔案(二個都刪除)

八、dos模式下建立 migration，切換至 d:\xampp\htdocs\laravelvuenote，輸入

php artisan make:migration create_notes_table

修改laravelvuenote/database/migrations/XXXXX(日期)_xxxx(流水號)_create_notes_table.php

於up函數中加入

Schema::create('notes', function (Blueprint $table) {
$table->increments('id');
$table->string('title');
$table->string('content');
$table->timestamps();
});

於down函數中加入

Schema::drop('notes');

九、建立資料庫

dos模式下

php artisan migrate

十、新增model
dos模式下

php artisan make:model Note

十一、修改app\Note.php

＜?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Note extends Model
{
  //
  protected $table ='notes';
  public $fillable = ['title','content'];
}

十二、建立controller

php artisan make:controller NoteController --resource

十三、修改app\Http\Controllers\NoteController.php

＜?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Note;
use Validator;
use App\Http\Requests;
use Response;
use Illuminate\Support\Facades\Input;
class NoteController extends Controller
{
    public function api()
    {    
      return view('/api');       
    }
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $notes = Note::latest()->paginate(6);  //每頁為6
        $response = [
          'pagination' => [
            'total' => $notes->total(),
            'per_page' => $notes->perPage(),
            'current_page' => $notes->currentPage(),
            'last_page' => $notes->lastPage(),
            'from' => $notes->firstItem(),
            'to' => $notes->lastItem()
          ],
          'data' => $notes
        ];
        return response()->json($response);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $this->validate($request,[
          'title' => 'required',
         'content' => 'required',
       ]);
     
        $create = Note::create($request->all());
        return response()->json($create);
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
      $this->validate($request,[
        'title' => 'required',
        'content' => 'required',
      ]);
      $edit = Note::find($id)->update($request->all());
      return response()->json($edit);
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        Note::find($id)->delete();
        return response()->json(['done']);
    }
}

十四、修改routes\web.php

＜?php
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
//Route::get('/', function () {
//    return view('welcome');
//});
Route::get('/', 'NoteController@api');
Route::get('/api', 'NoteController@index');
Route::resource('vuenotes','NoteController');

十五、建立頁面
在這邊我們使用jQuery、Bootstrap、toastr、Font awesome以及Vue.js 2

在resources/views建立app.blade.php

＜!DOCTYPE html>
＜html lang="en">
  ＜head>
    ＜meta charset="utf-8">
    ＜meta http-equiv="X-UA-Compatible" content="IE=edge">

接著新增檔案 api.blade.php

最後在public/js/下新增note.js

Vue.http.headers.common['X-CSRF-TOKEN'] = $("#token").attr("value");
new Vue({
  el :'#manage-note',
  data :{
    notes: [],
    pagination: {
      total: 0,

    },
    offset: 4,
    formErrors:{},
    formErrorsUpdate:{},
    newnote : {'title':'','content':''},
    fillnote : {'title':'','content':'','id':''}
  },
  computed: {
    isActived: function() {
      return this.pagination.current_page;

十六、開啟主機

php artisan serve

Laravel任務排程支援HourlyAt指定時間

在Laravel設定排程的方式很簡單，只要先做好

* * * * * php /path/to/artisan schedule:run >> /dev/null 2>&1

* * * * * /usr/bin/php-cli /path/to/artisan schedule:run 1>> /dev/null 2>&1

if (empty($_GET) === false) {
    foreach ($_GET as $key => $value) {
        $_SERVER['argv'][] = $key;
    }
}

然後每分鐘都會去執行 app/Console/Kernel@schedule的內容
在後續的版本，還可以指定每小時跑之外，也可以指定每小時的幾分執行！

$schedule->command('task1')->hourlyAt(30);

$schedule->command('task1')
    ->weekdays()
    ->hourlyAt(30);

想深入瞭解Laravel生態、框架、套件的好文章

A brief overview of the Laravel Ecosystem 這篇文章是由國外Pascal Baljet所寫的文章，文章介紹了Laravel的框架、元件、開發環境、其他用途的套件以及官方的相關平台，很值得想深入理解框架的朋友。

Laravel教學上學期結束


這學期的產業學院PHP課程，由之前的CodeIgniter改為Laravel課程，在上半學期主要以Route、MVC、Controller、DB…..為主軸，也就是以Laravel的基礎為主。同學在課程結束時，可以做基本的小範例。
在下學期則會更進階，並加上WebAPI的課程，讓同學可以結合手機程式一起做開發。
