aspnetcore，出现角度错误NodeInvocationException：60000ms之后，节点调用超时

Question

我在yo generator-aspnetcore-spa 运行应用程序后就遇到问题

处理请求时发生未处理的异常。

NodeInvocationException：60000ms之后，节点调用超时。您可以通过在NodeServicesOptions上设置InvocationTimeoutMilliseconds属性来更改超时持续时间。

调试的第一步是确保Node.js函数始终调用提供的回调（或同步引发异常），即使遇到错误也是如此。否则，.NET代码无法知道它已完成还是失败。Microsoft.AspNetCore.NodeServices.HostingModels.OutOfProcessNodeInstance + d__13.MoveNext（）

和红色在这条线上

AspNetCore._Views_Home_Index_cshtml + d__31.MoveNext（）in Index.cshtml + ViewData [“ Title”] =“ Home Page”;

这是我的package.json的样子

我的应用程序运行良好，我不知道出现此问题的原因是什么

Answer 1

问题出在aspnet-prerendering模块中，它在View >> Home >> Index.csHtml中看起来像这样

<app asp-prerender-module="ClientApp/dist/main-server">Loading...</app>

然后，当我删除它时，该应用程序运行正常

<app>Loading...</app>

但是当然没有服务器端渲染，因此当我完成开发应用程序后，我在项目的根目录中写入了此命令

webpack --config webpack.config.vendor.js
webpack

并恢复了

<app asp-prerender-module="ClientApp/dist/main-server">Loading...</app>

它按应有的方式工作:)

Answer 2

我们将站点托管在Azure中，而对我来说，解决方案是将此配置键/值添加到“应用程序”设置中。

密钥：WEBSITE_NODE_DEFAULT_VERSION
值：6.9.1

我想您也可以将其添加到appsetting.json或web.config中。
