1 - Laravel 5.2 Router

參考：Larvel 5 實務專題範例教學

一開始設定http://www.laravel.wingpage.net/指向/public/

---

路由系統

全部link都會經過app/Http/routes.php進行處理再分配去不同的檔案

//http://www.laravel.wingpage.net/
Route::get('/', function () { //另外有Route::post
    return view('welcome'); // link to -> resources/views/welcome.blade.php
});

//http://www.laravel.wingpage.net/student/abc
Route::get('student/{student_no}',function($student_no){
	return "學號：".$student_no;
});

條件處理

Route::get('student/{student_no}',function($student_no){
	return "學號：".$student_no;
})->where(['student_no'=>'s[0-9]{10}']);//條件 正則表達式 Regex
//http://www.laravel.wingpage.net/student/s1234567890
//學號：s1234567890

//另一種寫法
Route::pattern('student_no','s[0-9]{10}');//條件 正則表達式 Regex
Route::get('student/{student_no}',function($student_no){
	return "學號：".$student_no;
});

不符合條件 : http://www.laravel.wingpage.net/student/abc

Route::get('student/{student_no}/score/{subject?}',function($student_no, $subject = null){
	//如果無輸入subject 顯示 "所有科目"
	return "學號：".$student_no. "的".((is_null($subject))?" 所有科目":$subject). "成績";
})->where(['subject'=>'(chinese|english|math)']);//if subject有輸入只可以是chinese or english or math

//http://www.laravel.wingpage.net/student/s1124/score/english
//學號：s1124的english成績
//http://www.laravel.wingpage.net/student/s1124/score
//學號：s1124的所 有科目成績
//http://www.laravel.wingpage.net/student/s1124/score/abc
//不符合條件 -> error

這樣寫會令{student_no}的條件失效

群組

將同樣是"student"開頭的Group埋一齊 同時可共用{student_no}的條件

Route::pattern('student_no', 's[0-9]{10}'); //條件 正則表達式 Regex
Route::group(['prefix' => 'student'], function () {
    //student/{student_no}
    Route::get('{student_no}', function ($student_no) {
        return "學號：" . $student_no;
    });
    //student/{student_no}/score/{subject?}
    Route::get('{student_no}/score/{subject?}', function ($student_no, $subject = null) {
        //如果無輸入subject 顯示"所有科目"
        return "學號：" . $student_no . "的" . ((is_null($subject)) ? " 所有科目" : $subject) . "成績";
    })->where(['subject' => '(chinese|english|math)']);
});

路由命名

可讀性更高

Route::pattern('student_no', 's[0-9]{10}'); //條件 正則表達式 Regex
Route::group(['prefix' => 'student'], function () {

    Route::get('{student_no}', [
        'as'   => 'student',//命名 “看圖” 但仲未知有咩用...
        'uses' => function ($student_no) {//可以指向Controllers
            return "學號：" . $student_no;
        },
    ]);

    Route::get('{student_no}/score/{subject?}', [
        'as'   => 'student.score',
        'uses' => function ($student_no, $subject = null) {
            //如果無輸入subject 顯示"所有科目"
            return "學號：" . $student_no . "的" . ((is_null($subject)) ? " 所有科目" : $subject) . "成績";
        },
    ])->where(['subject' => '(chinese|english|math)']);

});
