c# - 为什么我的 Azure Function App(根据数据生成 PDF 文件)会超时？

标签 c# azure azure-functions

我在 .NET Core 2.1 上的 Visual Studio 2019 中创建了一个 Azure Function App。我的函数获取一组数据(小于 1 MB)并根据 HTML 模板(使用 NuGet 包 OpenHtmlToPdf )生成数据的 PDF 报告。

该函数由 Azure 服务总线队列触发。

当我在本地运行函数应用程序时，它可以完美运行，并且我的 local.settings.json 指向 Azure 上的队列。我向队列发送一条消息，一切都在几秒钟内按预期工作/完成。但是，当我将其部署到 Azure 并触发它时，它在工作几分钟后在 PDF 生成过程中超时。其他一切都会正常工作，直到到达此代码块(在 LogInformation() 调用之后):

                _log.LogInformation("Converting template and content into PDF file...");
                pdf = Pdf
                    .From(content)
                    .OfSize(PaperSize.A4)
                    .WithoutOutline()
                    .WithMargins(1.25.Centimeters())
                    .Portrait()
                    .Comressed()
                    .Content();
                _log.LogInformation("Finished converting template and content into PDF file");

它永远不会到达第二个 LogInformation("Finished...") 调用，在执行 Pdf 调用时在此点之前超时。

以下是 App Insights 日志的示例(首先是我记录的消息，然后是超时异常):

是的，我已经尝试增加超时值(直到我们的服务计划的最大值 10 分钟) - 但它仍然超时。尽管在我的本地计算机上执行只需要几秒钟。

此外，我已经检查、仔细检查、三重检查所有 Function App 配置设置。 (我应该提到，我的公司还有其他几个用 .NET Core 2.1 编写的 Azure Function 应用程序，运行良好)。

我做错了什么？难道只是因为 Azure Functions 不适合处理资源密集型操作(例如生成 PDF)吗？

最佳答案

我面临着类似的问题，也需要密集的CPU。在我看来，问题出在 Azure Functions 方面。您可以做的是使用 Durable Functions 并将此 PDF 生成传递给事件。我不确定它是否能解决您的问题，但值得一试。

关于c# - 为什么我的 Azure Function App(根据数据生成 PDF 文件)会超时？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59184717/
