Php Laravel：启动下载并同时在Blade 中显示Flash消息

发布于04月04日

当一个用户请求开始下载，同时向他发送一条flash消息时，你该怎么做？

A. Flash message (example):. return redirect()->route('success')->with('success', 'hello');.

B. Start download (example):. return \Illuminate\Support\Facades\Storage::download($path);.

C. Example which does not work. But it should be a mix of both examples from above:

return \Illuminate\Support\Facades\Storage::download($path)->with('success', 'hello');

推荐答案

As far as I know, HTTP responses are singular operations. It means you can't download and return messages at the same time.

但你可以在100和101之前存档.

在您的Web路由中，添加以下内容

Route::get('/download-file', function () {
    $path = 'path/to/your/file.pdf';
    return \Illuminate\Support\Facades\Storage::download($path);
})->name('download.file');

当你点击"下载按钮"时，显示下载页面，并返回.

return redirect()->route('show.download.page')->with('success', 'file is ready to download!');

在这个视图中，像这样添加.

<body>
@if(session('success'))
    <div class="alert alert-success">
        {{ session('success') }}
    </div>
@endif

<script>
    window.onload = function() {
        window.location.href = "{{ route('download.file') }}";
    }
</script>
</body>
