What I have done is, written two separate route one to verify and one to download. On success of one ajax I have triggered window.open(downloadUrl,'_blank') to download in separete window. It is not the way asked but it prevents any upcoming errors as verify url will sort that
我所做的是，写了两个单独的路线，一个是验证，一个是下载。在一个 ajax 成功时，我触发了 window.open(downloadUrl,'_blank') 在单独的窗口中下载。这不是询问的方式，但它可以防止任何即将发生的错误，因为验证 url 将对其进行排序
$.ajax({
url: verifyUrl,
type: 'get',
cache: false,
data: null,
error: function (err){$('#ajax_loader_div').hide();},
success: function(response) {
console.log(response);
$('#ajax_loader_div').hide();
if (response.status == 'success')
{
window.open(downloadUrl,'_blank');
}else if(response.status == 'error')
{
//show error
}
}
});

for that you need to set the header with response object. Please see the below code.
为此，您需要使用响应对象设置标头。请看下面的代码。
$headers = array(
'Content-Type'=> 'application/pdf'
);
$file_path = $request->input('file_path');
//TODO: you have to split the file name from url
return Response::download($file_path, '<filename>', $headers);
I hope this code will help you
我希望这段代码能帮助你

return Response::download($file_path, '<filename>', $headers);
返回 Response::download($file_path, '<filename>', $headers);
It's return response, not download file!
这是返回响应，而不是下载文件！
