我正在创建一个搜索功能，我正在尝试使用搜索表单使id出现在url上。 当我手动输入search？id=1时，它得到了正确的项目，但当使用我的表单时，它似乎没有得到id，也没有将其添加到url的末尾，不知道我做错了什么，但将感谢您的帮助。

路线

    Route::get('/search', 'HomeController@search')->name('search');
    Route::resource('home', 'HomeController');

控制器

    public function search(Request $request){
        $post = Post::where('id', $request->id)->first();
        $posts = Post::all();

        if (Post::where('id', '=', Input::get('id'))->exists()) {
            return view('Frontend::pages.press.show', compact('post', 'posts'));
        }else if (Post::where('id', '=', 0)) {
            return view('Frontend::pages.press.press', compact('post', 'posts'));
        }
    }
