Я пытаюсь использовать Puppeteersharp для создания PDF-файлов на сервере и отправки их обратно клиенту. Все это работает локально через localhost и IIS Express на ПК с Windows 11.
Однако, когда я развертываю это на виртуальной машине Azure с IIS (64-разрядная версия Windows Server 2019, 8 ГБ ram) процесс завершается сбоем, потому что не удается загрузить Chrome – и я не знаю, что попробовать...
- Я переключился из пути к папке TEMP в каталог inetpub, где все разрешения ДОЛЖНЫ быть правильными.
- Я могу сверлить загрузить .zip по URL-адресу ниже
- Я могу скачать его прямо из Chrome

Chromium — это класс-оболочка, который я написал для Puppeteersharp...
Вот код:
Контроллер API данных конечная точка:
[HttpPost]
[Route("some-route")]
public async Task GeneratePdf(RequestDto request)
{
var chromium = new Chromium();
await chromium.DownloadChromium();
Stream stream = await chromium.CreateStreamAsync(request.Html);
MemoryStream ms = new MemoryStream();
stream.CopyTo(ms);
var result = new HttpResponseMessage()
{
Content = new ByteArrayContent(ms.ToArray()),
StatusCode = HttpStatusCode.OK
};
result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = $"{request.pdfName}.pdf"
};
return ResponseMessage(result);
}
