asp.net core 设置默认文档index.html

参考：https://jingyan.baidu.com/article/6079ad0e3e212168fe86db75.html

在Startup.cs的Configure添加

app.UseFileServer();

示例：

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseHsts();
    }

    app.UseHttpsRedirection();
    app.UseStaticFiles();
    //开启index.html
    app.UseFileServer();

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

注：目前这一够代码的位置没研究，应该是随便就行
