Php Laravel Snappy抛出错误500，无进一步信息

我想使用barryvdh\laravel snappy创建PDF文件。我遵循了github页面上的所有步骤，但是每当我使用诸如

$pdf->output（）；
$pdf->下载（“test.pdf”）；

我得到一个服务器错误

我尝试在windows上使用安装程序和编写器依赖项安装WKTHLTOPDF。我清除了缓存，使用了composer更新，dump autoload等等

这是我的控制器中的功能：

公共函数createInvoice（$id）
{
$data=[“数据”=>“数据”]；
$pdf=pdf:：loadView（“invoice.default”，$data）；
dd（$pdf）；
返回响应（）->json([
“pdf”=>base64_编码（$pdf->output（））
]);
}

我的snappy.php配置：

'pdf'=>[
“已启用”=>true，
“binary”=>基本路径（“vendor/h4cc/wkhtmltopf-amd64/bin/wkhtmltopf-amd64”），
'timeout'=>false，
“选项”=>[]，
“env”=>[]，
],
“图像”=>[
“已启用”=>true，
“binary”=>基本路径（'vendor/h4cc/wkhtmltoimage-amd64/bin/wkhtmltoimage-amd64'），
'timeout'=>false，
“选项”=>[]，
“env”=>[]，
],

My app.php配置：

“提供者”=>[
.
.
Barryvdh\Snappy\ServiceProvider:：类，
.
.
.
“别名”=>[
.
.
'PDF'=>Barryvdh\Snappy\Facades\SnappyPdf:：class，
“SnappyImage”=>Barryvdh\Snappy\Facades\SnappyImage:：class，

在$pdf上使用dd时，在调用output、download、inline等函数之前，我会得到以下响应：

将二进制路径更改为

  'pdf' => array(
        'enabled' => true,
        'binary'  => '/usr/local/bin/wkhtmltopdf', //for ubuntu
        // 'binary'  => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe"', //for windows
        'timeout' => false,
        'options' => array(),
        'env'     => array(),
    ),
    'image' => array(
        'enabled' => true,
        'binary'  => '/usr/local/bin/wkhtmltoimage', //for ubuntu
        // 'binary'  => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltoimage.exe"', //for windows
        'timeout' => false,
        'options' => array(),
        'env'     => array(),
    ),

您已经为ubuntu设置了。

您正在使用哪个操作系统？Microsoft Windows 10。这解决了我的代码问题。当我使用真正的blade创建pdf时，我再次遇到同样的错误。在服务器中，您仍然需要使用基于服务器操作系统的二进制路径。您知道，为什么我在文件内容较多时出现服务器错误吗？@Commander不是因为有更多的内容，而是因为您试图使用的内容类型。@Commander似乎您需要给出该图像的正确路径，您使用的是错误的路径。

  'pdf' => array(
        'enabled' => true,
        'binary'  => '/usr/local/bin/wkhtmltopdf', //for ubuntu
        // 'binary'  => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe"', //for windows
        'timeout' => false,
        'options' => array(),
        'env'     => array(),
    ),
    'image' => array(
        'enabled' => true,
        'binary'  => '/usr/local/bin/wkhtmltoimage', //for ubuntu
        // 'binary'  => '"C:\Program Files\wkhtmltopdf\bin\wkhtmltoimage.exe"', //for windows
        'timeout' => false,
        'options' => array(),
        'env'     => array(),
    ),
