Question

laravel中的路由参数有问题，这是main.blade.php：

    <body>
<div class="flex-center position-ref full-height">
    <div class="content">
        <div class="title m-b-md">
            Generate Your Domain Now
        </div>
        {!! Form::open(['route'=>'generatorindex' , 'method' => 'post']) !!}
            <input type="hidden" name="_token" value="{!! csrf_token() !!}">
            <input name="inputkeyword" type="text" placeholder="Enter your keyword">
            <button type="submit" value="Generate"></button>
        {!! Form::close() !!}

    </div>
</div>
</body>

这是控制器中的功能：

public function generator(Request $inputkeyword)
    {
        echo $productname = $inputkeyword->input('inputkeyword');

    }

最后，这是路线：

Route::any('/generator/{inputkeyword}', [ 'as' => 'generatorindex', 'uses' => 'MainController@generator' ]);

但它返回：

    ErrorException in UrlGenerationException.php line 17:
Missing required parameters for [Route: generatorindex] [URI: generator/{inputkeyword}]. (View: C:\Users\Mostafa\myapp\resources\views\main.blade.php)

我做错了什么？我应该在哪里定义inputkeyword参数？

Answer 1

<body>
    <div class="flex-center position-ref full-height">
        <div class="content">
            <div class="title m-b-md">
                Generate Your Domain Now
            </div>
            {!! Form::open(['route'=> ['generatorindex', '??'] , 'method' => 'post']) !!}
                <input type="hidden" name="_token" value="{!! csrf_token() !!}">
                <input name="inputkeyword" type="text" placeholder="Enter your keyword">
                <button type="submit" value="Generate"></button>
            {!! Form::close() !!}

        </div>
    </div>
</body>

要么在我写“??”的地方传递一些值在上面的代码中

OR

通过后缀使inputkeyword参数可选它与“？”到这样的route.php文件：

Route::any('/generator/{inputkeyword?}', [ 'as' => 'generatorindex', 'uses' => 'MainController@generator' ]);

请阅读：

https://laravel.com/docs/5.3/helpers#method-route

https://laravel.com/docs/5.3/routing#parameters-optional-parameters

修改

根据您的要求，您在聊天时告诉我：

<强> routes.php文件

Route::post('generator', [ 'as' => 'generatorindex', 'uses' => 'MainController@generator' ]); Route::get('generator/{inputkeyword}', [ 'as' => 'generatorindexurl', 'uses' => 'MainController@generatorindexurl' ]);

<强> MainController.php

public function generator() { return redirect()->route('generatorindexurl', request('inputkeyword')); } public function generatorindexurl() { dd(request()); }

查看

<body> <div class="flex-center position-ref full-height"> <div class="content"> <div class="title m-b-md"> Generate Your Domain Now </div> {!! Form::open(['route'=> ['generatorindex'] , 'method' => 'post']) !!} <input type="hidden" name="_token" value="{!! csrf_token() !!}"> <input name="inputkeyword" type="text" placeholder="Enter your keyword"> <button type="submit" value="Generate"></button> {!! Form::close() !!} </div> </div> </body>

路线参数在laravel中不起作用
