带有React的ASP.NET Core-431请求标头太长

Question

我有一个以dotnet run命令开头的dotnet应用程序。我还有一个以yarn start开头的React应用。

当我在localhost:3000（反应应用所在的位置）上打开浏览器时，服务器日志如下所示：

在加载页面的15秒后，但是在浏览器控制台中出现关于bundle.js 431错误的错误。

如果我使Kestrel服务器的RequestHeaders最大总大小更大，则会发生相同的事情，但是这种情况会持续更长的时间，最终结果是500服务器错误而不是431。

此外，如果我尝试使用邮递员向服务器发出简单的DELETE请求，结果几乎相同。好像请求被卡在无限循环中，然后返回431。

Startup.cs中可能相关的行：

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

// In production, the React files will be served from this directory
services.AddSpaStaticFiles(configuration =>
     {
          configuration.RootPath = "client/build";
     }
);


app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller}/{action=Index}/{id?}");
            }
);
app.UseSpaStaticFiles();
app.UseSpa(spa =>
            {
                if (env.IsDevelopment())
                    spa.UseProxyToSpaDevelopmentServer("http://localhost:3000");
            }
);
发生了什么事？

我有一个以dotnet run命令开头的dotnet应用程序。我也有一个React应用程序，我从yarn start开始。当我在localhost：3000（react应用程序所在的位置）上打开浏览器时，...

我遇到了同样的问题，但是在Angular中，在localhost开发期间使用asp.net内核。对我来说，解决方案是在我的package.json文件内的“开始”脚本中设置节点的标头大小。
