Question

以下路由正常，该方法可以遍历项目： http://localhost/library/api/books

$app->get('/api/books', 'Book:getBooks');

班级：

class Book {
    :
    :
    public function __construct($container) { 
        $this->container = $container; 
    }    

    public function getBooks($request, $response) {
        :
        :
        echo '{"book": ' . json_encode($books) . '}';        
    }

    public function getBook($id) {
        echo json_encode($id); 
    }
}

使用由＆＃39; id＆＃39;标识的路由模式调用方法如下所示，不返回任何内容（空$ id）： http://localhost/library/api/books/10

$app->get('/api/books/{id}', 'Book:getBook');

似乎＆＃39; id＆＃39;没有通过。

如何通过标识符正确处理路由模式？

Answer 1

正如我在评论中所说，请告诉我们开发控制台在类别控制台和网络下的chrome中所说的内容。

我不确定你为什么选择创建这样的路线，但我会按照这种方式创建它们（看起来也更整洁）：

Route::group(['prefix' => 'book'], function ()
{
    Route::get('/', ['as' => 'index', 'uses' => 'BookController@index']);
    Route::get('new', ['as' => 'new', 'uses' => 'BookController@new']);
    Route::get('show/{bookID}', ['as' => 'show', 'uses' => 'BookController@show']);
    Route::get('edit/{bookID}', ['as' => 'edit', 'uses' => 'BookController@edit']);
    Route::post('create', ['as' => 'create', 'uses' => 'BookController@create']);
    Route::post('update', ['as' => 'update', 'uses' => 'BookController@update']);
    Route::delete('destroy/{deviceID}', ['as' => 'destroy', 'uses' => 'BookController@destroy']);
});

BookController看起来像这样：

class BookController extends Controller
{
    // this shows all books and adds a pagination of 15 items, which you can easily increase or decrease
    public function index()
    {
        $books = DB::table('books')->paginate(15);
        return view('books.index', compact('books');
    }

    public function new()
    {
        $book = new Book;

        return view('books.new', [
            'books' => $books,
            'type' => 'new'
        ]);
    }

    public function create(Request $request)
    {
        $this->validate($request, Book::$rules); // I put the rules inside of the Book Model, but you could just add them here aswell

        $data = $request->all();

        $book = new Book();
        $book->fill($data);

        if($book->save())
        {
            return redirect()->route('new')->with('success', 'success.');
        }
        else
        {
            return redirect()->route('new')->with('error', 'Error.')->withInput();
        }

    public function edit(Request $request, $bookID = 0)
    {
        $books    = Book::all();
        $newBook  = new Book;
        $book     = Book::find($bookID);

        if(is_null($book))
        {
            $books = Device::paginate(10); // paginate if you like to
            return view('books.index', [
                'books' => $books,
                'errorNoBook' => 'No BOok'
            ]);
        }
        else
        {
            $bookID = $book->id;
        }

        return view('books.edit', [
            'allBooks' => $allBooks,
            'new' => $new,
            'book' => $book,
        ]);
    }
 }

Answer 2

以下是我发现的简单工作解决方案：

:
:
public function getBook($request, $response) {
    $route = $request->getAttribute('route'); // route object
    $id = $route->getArgument('id'); // route object identifier
    $book = $this->db->table('books')->where('id', $id)->first();
    echo json_encode($book); 
}

使用Slim标识的路由模式
