在laravel中将变量传递到route时找不到404

laravel php

BARNOWL · 技术社区 · 6 年前

我试着运行一个ajax调用,我不断地

http://127.0.0.1:8000/books/rate/2 404(未找到)

所以它很好地得到了id,但是显示了404错误。

route.php路径

Route::post('rate/{book_id}','BookController@rate')->name('rate');

主.js

$('#sub').submit(function(e){
    var owl = $(this).attr("data");
    var route = JSON.parse(owl);

        $.ajax({
            type:"POST",
            url:"rate/" + route.id,
            headers: {
                    'X-CSRF-TOKEN':  $('meta[name="csrf-token"]').attr('content')
              }, 
            success:function(res){
               console.log("owls");
            }
       });

    event.preventDefault();

});

控制器 (图书管理员)

public function rate(Request $request, $book_id)
{
    $book = Book::find($book_id);
    $rating = $book->ratings()->where('user_id', auth()->user()->id)->first();

    if(is_null($rating)){
        $ratings = new Rating();
        $ratings->rating =  $request['rating'];
        $ratings->user_id = auth()->user()->id;
        $book->ratings()->save($ratings);
        return json_encode($book);
    }
    else{
        return redirect()->back()->with("status", "You already left a review");
    }
}

HTML格式

<form id="sub" data= "{{ $book }}">
   {!! csrf_field() !!}
   <div id="rateYo" data-rateyo-rating="{{  $book->userSumRating or 0}}"> ></div>
   <input name="rating" value='{{  $book->userSumRating  or 0 }}' type="hidden" id="val">
   <button type="submit" class="btn btn-primary mt-2">submit</button>
</form>

您使用的是ajax post,因此改为重定向使用json响应,如下所示

public function rate(Request $request, $book_id)
{
    $book = Book::find($book_id);
    $rating = $book->ratings()->where('user_id', auth()->user()->id)->first();

    if(is_null($rating)){
        $ratings = new Rating();
        $ratings->rating =  $request['rating'];
        $ratings->user_id = auth()->user()->id;
        $book->ratings()->save($ratings);
        return json_encode($book);
    }
    else{
       return response()->json(['status' => "You already left a review"]);
    }
}

添加并尝试此javascript代码

$.ajax({
        type:"POST",
        url:"http://127.0.0.1:8000/rate/" + route.id,
        headers: {
                'X-CSRF-TOKEN':  $('meta[name="csrf-token"]').attr('content')
          },
        data:{rating: $('#val').val()},
        success:function(res){
           console.log("owls");
        }
});

我认为您需要对javascript进行如下更改

$('#sub').submit(function(e){
      var owl = $(this).attr("data");
      var route = JSON.parse(owl);



         $.ajax({
            type:"POST",
            url:"http://127.0.0.1:8000/rate/" + route.id,
            headers: {
                    'X-CSRF-TOKEN':  $('meta[name="csrf-token"]').attr('content')
              }, 
            success:function(res){
               console.log("owls");
            }
         });

      event.preventDefault();


   });

这是因为在您的URL中,您得到的书籍比rate/{rate_id}早,这就是它显示404页未找到错误的原因!

就这样用吧:-

$.ajax({
            type:"POST",
            url:"{{url('rate/')}}" + route.id,
            headers: {
                    'X-CSRF-TOKEN':  {{ csrf_token() }}
              }, 
            success:function(res){
               console.log("owls");
            }
     });
