Question

我正在使用Laravel应用程序，通过该应用程序我可以从API（这是一个可执行的链接，在单击该链接时会打开PDF文档）中获取一些数据。我正在获取存储在变量中的数据，然后传递到视图，但是当我将其添加到定位标记的href属性中时，出现错误 Undefined variable：quotePdf 。

但是当我在dd之后获取数据并将其粘贴到锚链接标记中时，它可以正常运行

AJAX代码呈现视图

 $.ajax({
    type: "POST",
    url: "getquote",
    data: JSON.stringify(allData),
    contentType: "application/json",
    dataType: "json",
    cache: false,
    success: function(data){ 
      //The url that will render the view called quote.blade.php
      window.location.href="showquote" ;
    },
    error: function(data) {
        var errors = '';
        for(datos in data.responseJSON){
            errors += data.responseJSON[datos] + '\n';
        }
        alert(errors);
    }
});

获取代码并显示在前端的控制器

 public function createQuote(Request $request)
    {

        $quote = $this->global_Curl_Meta(
            $data, 'api/travel/create-quote')->data;

        //dd($quote);

        $quote_data = $quote;

        $quoteholder_name = $form['FirstName'] . ' ' . $form['MiddleName'] . ' ' . $form['LastName'];
        $quoteholder_email = $form['email'];
        $travel_plan = $plan;
        $quoteID = $quote_data->QuotationId;
        $quoteRef = $quote_data->QuoteNumber;

        $data = [
            'sts_quote_number' => $quoteRef
        ];

        //STS PDF Quote
        $quotePdf = $this->global_Curl_Meta(
            $data, 'api/v1/travel/sts-quote-doc')->data;

        //dd($quotePdf);

        //Get all teh variables and return to the view
        $quote_data = view("B2C::travel.quote", compact('quote_data', 'quoteholder_name', 'quoteholder_email', 'travel_plan' ,'phone' , 'quotePdf' ));

        return 'true';
    }

dd之后的浏览器响应

通过AJAX渲染称为quote.blade.php的视图，除quotePdf以外的所有变量都渲染良好

@section('content')

@php
//var_dump($quote_data);
$quote_number = $quote_data->QuoteNumber;
$quote_details = $quote_data->Calculation_Quote->Calculation;
@endphp
<div class="container">

<main class="top Quote">
  <h1 class="quote-title">Travel Insurance Quote
    <!-- Go Back --> 
    <a href="#" onclick="goBack()">  
      <span class="back-us"><i class="fas fa-arrow-left"></i>Back</span>
    </a> 
    <!--END-->
  </h1>
  <table class="table ref">
  <thead class="thead-dark">

Answer 1

尝试这个

$quote_data = view("travel.quote", ['quotePdf' => $quotePdf])->render();

否则使用with方法

$quote_data = view("travel.quote")->with('quotePdf',$quotePdf)->render();

Answer 2

尝试这样

<a href="{!! $quotePdf !!}" target="_blank">Print Quote </a>

Answer 3

我可能是错的，但这就是我所观察到的。

public function createQuote(Request $request)
            {

                $quote = $this->global_Curl_Meta(
                    $data, 'api/travel/create-quote')->data;

                //dd($quote);

                $quote_data = $quote;

                $quoteholder_name = $form['FirstName'] . ' ' . $form['MiddleName'] . ' ' . $form['LastName'];
                $quoteholder_email = $form['email'];
                $travel_plan = $plan;
                $quoteID = $quote_data->QuotationId;
                $quoteRef = $quote_data->QuoteNumber;

                $data = [
                    'sts_quote_number' => $quoteRef
                ];

                //STS PDF Quote
                $quotePdf = $this->global_Curl_Meta(
                    $data, 'api/v1/travel/sts-quote-doc')->data;

                //dd($quotePdf);

                //Get all teh variables and return to the view
                $quote_data = view("B2C::travel.quote", compact('quote_data', 'quoteholder_name', 'quoteholder_email', 'travel_plan' ,'phone' , 'quotePdf' ));

                return 'true';
            }

在您的紧凑函数中，您将“ phone”作为未在任何地方定义的条目进行传递，因此它将忽略此后的每个条目。尝试从压缩功能中删除“电话”。

Answer 4

而不是返回到base64字符串（$ quotePdf）进行查看。您可以执行以下操作。

$decoded = base64_decode ($quotePdf);

$pdf = fopen ('quote.pdf','w');

fwrite ($pdf,$decoded);

fclose ($pdf);

header("Content-type:application/pdf");

header("Content-Disposition:attachment;filename='quote.pdf'");

readfile("quote.pdf");

此代码将解码base64字符串并创建pdf文件。并下载相同的。如果要返回视图，可以将pdf保存在服务器中，并作为响应返回文件路径。

希望这会有所帮助！
