我目前正在使用.NET Core 2.2作为后端部分的VueJS应用程序。我正在研究它几个月，但当我从2.0更新到2.2时，它突然停止工作
我没有检测到我的Web API更改，我不知道为什么例如，我有一些控制器，每当我更改它们，然后使用web api时，都没有进行更改。我甚至可以删除整个文件，使用此文件的web api仍然可以正常工作！我得到的另一个问题是，当我创建新的控制器文件时，它也没有被检测到，我被我的旧控制器所困扰，无法更新它。检测到其他文件更新（至少如果我更改了vueJS前端）我还可以更改提供程序，删除用于web api的任何文件，未检测到更改。这可能是一个配置问题？
有什么我可以尝试再次更新的东西？
更新：我可以在后端更改我想要的内容，实际上它什么都不做。编译错误是我唯一需要关心的问题，就像应用程序不再使用代码一样。
这是我可以提供的一个例子：
我有一个控制器“InterventionController”，它检索有关操作的数据（我在法语环境中是法语，所以变量名称等将是法语）：
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Vue2Spa.Models;
using Vue2Spa.Providers;
namespace Vue2Spa.Controllers
{
[Produces("application/json")]
[Route("api/[controller]")]
[ApiController]
public class InterventionController : Controller
{
private readonly IInterventionProvider interventionProvider;
public InterventionController(IInterventionProvider interventionProvider)
{
this.interventionProvider = interventionProvider;
}
[HttpGet("[action]")]
public IActionResult Interventions([FromQuery(Name = "from")] int from = 0, [FromQuery(Name = "to")] int to = 5000)
{
var quantity = to - from;
if (quantity <= 0)
{
return BadRequest("La quantité doit être positive !");
}
else if (from < 0)
{
return BadRequest("Vous devez spécifier un indice de départ non nul !");
}
var allInterventions = interventionProvider.GetInterventions();
var result = new
{
TotalInterventions = allInterventions.Count,
Interventions = allInterventions.Skip(from).Take(quantity).ToArray()
};
return Ok(result);
}
}
// Others methods not useful for my example
}
它调用具有以下代码的提供程序：
using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.EntityFrameworkCore;
using Vue2Spa.Models;
namespace Vue2Spa.Providers
{
public class DBInterventionProvider : IInterventionProvider
{
private List<Intervention> interventions { get; set; }
DbContextOptionsBuilder<DepouillementTestContext> optionsBuilder = new DbContextOptionsBuilder<DepouillementTestContext>();
public DBInterventionProvider()
{
optionsBuilder.UseSqlServer(credentials); // Credentials are correct but not including it there for obvious reasons
using (var context = new LECESDepouillementTestContext(optionsBuilder.Options))
{
interventions = context.Intervention.ToList();
}
}
public List<Intervention> GetInterventions()
{
using (var context = new LECESDepouillementTestContext(optionsBuilder.Options))
{
interventions = context.Intervention.ToList();
}
return interventions;
}
// Others methods not useful for this example
}
}
我可以删除这些文件，我仍然可以访问我的操作web api
如果需要，这是我的startup.cs文件
using System;
using System.Reflection;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.SpaServices.Webpack;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Diagnostics;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Vue2Spa.Models;
namespace Vue2Spa
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc();
// Additional code for SQL connection
services.AddDbContext<DepouillementTestContext>(options =>
{
options.UseSqlServer(Configuration["ConnectionString"],
sqlServerOptionsAction: sqlOptions =>
{
sqlOptions.
MigrationsAssembly(
typeof(Startup).
GetTypeInfo().
Assembly.
GetName().Name);
//Configuring Connection Resiliency:
sqlOptions.
EnableRetryOnFailure(maxRetryCount: 5,
maxRetryDelay: TimeSpan.FromSeconds(30),
errorNumbersToAdd: null);
});
// Changing default behavior when client evaluation occurs to throw.
// Default in EFCore would be to log warning when client evaluation is done.
options.ConfigureWarnings(warnings => warnings.Throw(
RelationalEventId.QueryClientEvaluationWarning));
});
// Provider pour les interventions
services.AddSingleton<Providers.IInterventionProvider, Providers.DBInterventionProvider>();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
// Webpack initialization with hot-reload.
app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
{
HotModuleReplacement = true,
});
}
else
{
app.UseExceptionHandler("/Home/Error");
}
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
routes.MapSpaFallbackRoute(
name: "spa-fallback",
defaults: new { controller = "Home", action = "Index" });
});
}
}
}
提前致谢，
好吧，我已经找到了为什么我遇到这个问题，我觉得有点愚蠢但是，现在它正在运作。
当我从.NETCORE 2.0升级到2.2时，我没有改变我的launch.json，我所要做的就是改变
"program": "${workspaceFolder}/content/bin/Debug/netcoreapp2.0/Vue2Spa.dll",
通过
"program": "${workspaceFolder}/content/bin/Debug/netcoreapp2.2/Vue2Spa.dll",
