发布到Azure，asp.net核心React应用 [英] Publish to azure, asp.net core React app
问题描述
我在Google上搜索了很多，但还没有弄清楚该怎么做.我有一个要在azure上部署的Web应用程序.我生成了链接，但是使用我的React组件的Routes返回了500状态代码.
I've googled alot, and i haven't figured out how to do it. I have a web app that i would like to deploy on azure. I generates the link but the Routes that use my React components, return a 500 status code.
对于我的组件，我使用的是JSX，我将它们放在/js下的wwwroot文件夹中(我没有使用ES16).
For my components i'm using JSX and i have them in the wwwroot folder under/js (i'm not using ES16).
我需要一些东西将其捆绑并将jsx处理为js，对吗?我不明白为什么它可以在本地主机上工作.
I need something to bundle it and process that jsx into js right? I don't understand why it works on localhost.
在Startup.cs上，配置方法，我添加了如下脚本:
On Startup.cs, configure method, i added the scripts like this:
app.UseReact(config =>
{
config
.AddScript("~/js/test.jsx")
.AddScript("~/js/users.jsx")
.AddScript("~/js/userCards.jsx")
.AddScript("~/js/userInfo.jsx")
.AddScript("~/js/cards.jsx")
.AddScript("~/js/user.jsx")
.AddScript("~/js/addCard.jsx")
.AddScript("~/js/cardImages.jsx")
.SetJsonSerializerSettings(new JsonSerializerSettings
{
StringEscapeHandling = StringEscapeHandling.EscapeHtml,
ContractResolver = new CamelCasePropertyNamesContractResolver()
});
});
很抱歉，这是一个愚蠢的问题，但是我似乎找不到关于asp.net核心的很好的解释.
I'm sorry if it is a silly question, but i can't seem to find a good explanation for asp.net core.
我正在使用VS2017，asp.net core 1.0.4和React.AspNet 3.0.1
I'm using VS2017, asp.net core 1.0.4 and React.AspNet 3.0.1

它说我没有app.AddReact或app.UseReact，但是我俩都没有...
It says i don't have app.AddReact nor app.UseReact, but i have then both...
public void ConfigureServices(IServiceCollection services)
{
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
services.AddReact();
services.AddServerSentEvents();
services.AddServerSentEvents<INotificationsServerSentEventsService, NotificationsServerSentEventsService>();
services.AddMvc();
services.AddSingleton<HttpClient>();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IServiceProvider serviceProvider)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseBrowserLink();
}
else
{
app.UseDeveloperExceptionPage();
app.UseBrowserLink();
}
app.MapServerSentEvents("/see-heartbeat");
app.MapServerSentEvents("/sse-notifications", serviceProvider.GetService<NotificationsServerSentEventsService>());
app.UseStatusCodePagesWithReExecute("/Error/{0}");
app.UseReact(config =>
{
config

.SetJsonSerializerSettings(new JsonSerializerSettings
{
StringEscapeHandling = StringEscapeHandling.EscapeHtml,
ContractResolver = new CamelCasePropertyNamesContractResolver()
});
});
app.UseDefaultFiles();
app.UseStaticFiles();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Index}/{action=Index}/{id?}");
});
}
推荐答案
这是因为您的PC上有JavaScript引擎，而Azure中没有. 摘自: https://github.com/reactjs/React.NET/issues/400 (实际上是有关如何使React工作的完整说明)
That's because JavaScript Engine you have on your PC and not in Azure. Taken from: https://github.com/reactjs/React.NET/issues/400 (actually a complete instruction on how to get React working)
结合使用以下指南，我能够使应用程序在发布到Azure时正常工作:
I was able to get the application working when published to Azure using a combination of these guides:
https://github.com/Taritsyn/JavaScriptEngineSwitcher/wiki/JS引擎注册
在第一本指南中，我分别安装了依赖项:
From the first guide, I installed dependencies separately:
Uninstall-Package React.AspNet
Install-Package JavaScriptEngineSwitcher.Core
Install-Package JavaScriptEngineSwitcher.Msie (May not be needed)
Install-Package JSPool
Install-Package JavaScriptEngineSwitcher.ChakraCore
Install-Package JavaScriptEngineSwitcher.ChakraCore.Native.win-x64 (Selected native implementation)
Install-Package Microsoft.ChakraCore (I think this is key to enabling ChakraCore on the server)
Install-Package React.AspNet -IgnoreDependencies
从第二本指南中，我安装了一个软件包以在.NET Core 1.X中启用JavaScriptEngineSwitcher配置:
From the second guide, I installed a package to enable JavaScriptEngineSwitcher configuration in .NET Core 1.X:
Install-Package JavaScriptEngineSwitcher.Extensions.MsDependencyInjection
在Startup.cs
In Startup.cs
ConfigureServices():
services.AddJsEngineSwitcher(options => options.DefaultEngineName = ChakraCoreJsEngine.EngineName).AddChakraCore();
