帶有ASP.NET Core 1.0 MVC WebApi的EF Core 1.0錯誤404

Question

我有一個使用EF Core 1.0和ASP.NET Core 1.0 MVC WebApi的小型應用程序，在紅est自托管方案（IIS Express）中運行良好。當我在IIS 7.0上發布時，調用方法使用EF時出現404錯誤核心，但是當我調用不使用EF核心的方法時，它可以完美地工作。

[Route("api/[controller]")]
public class MyModelController : Controller
{
    private readonly IExampleRepository _exampleRepository;

    public MyModelController(IExampleRepository exampleRepository)
    {
        _exampleRepository = exampleRepository;
    }

    [HttpGet("GetTestAll")] //RUN PERFECTLY ON IIS
    public IEnumerable<string> GetTest()
    {
        return new string[] { "value1", "value2", "value3", "value4" };
    }

    // GET: api/mymodel
    [HttpGet("", Name = "GetAll")] //ERROR 404 ON IIS
    public IActionResult Get()
    {
        try
        {
            return Ok(_exampleRepository.GetAll().Select(x => Mapper.Map<MyModelViewModel>(x)));
        }
        catch (Exception exception)
        {
            //logg exception or do anything with it
            return StatusCode((int)HttpStatusCode.InternalServerError);
        }
    }

...

public class Startup
{
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
            .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);

        builder.AddEnvironmentVariables();
        Configuration = builder.Build();
    }

    public IConfigurationRoot Configuration { get; set; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        var configurationSection = Configuration.GetSection("ConnectionStrings:DefaultConnection");
        services.AddDbContext<DataBaseContext>(options => options.UseSqlServer(configurationSection.Value));
        // Add framework services.

        services.AddMvc();
        services.AddScoped<IExampleRepository, ExampleRepository>();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        Mapper.Initialize(config =>
        {
            config.CreateMap<MyModel, MyModelViewModel>().ReverseMap();
        });

        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();

        app.UseDefaultFiles();
        app.UseStaticFiles();

        app.UseMvc();
    }
}

提取project.json

"Microsoft.ApplicationInsights.AspNetCore": "1.0.0",
"Microsoft.AspNetCore.Mvc": "1.0.0",

在IIS服務器上將EF Core 1.0與ASP.NET Core 1.0 MVC WebApi一起使用的配置是什么。

謝謝你的幫助。 您將在此URL上找到一個應用程序，該應用程序回答了在IIS 7.0上被脈沖后將給出404錯誤的相同條件

在紅est自托管方案（IIS Express）中運行良好。當我在IIS 7.0上發布時，出現404錯誤

它看起來像是與您的發布過程有關的問題，而不是與EF有關的問題，因為它在調試時起作用。

_exampleRepository.GetAll()或Automapper可能都需要一個已發布項目中缺少的文件。

在project.json文件中，您應該包括要在publish過程中復制的所有內容的列表。 例如我的看起來像這樣

"publishOptions": {
    "include": [
      "wwwroot",
      "web.config",
      "appsettings.Development.json",
      "appsettings.Production.json",
      "Views",
      "Resources/*"
    ]
}

使用路由的最佳實踐是在單獨的路由屬性中定義路由。

因此，您的代碼應如下所示：

[Route("api/[controller]")]
public class MyModelController : Controller
{
    private readonly IExampleRepository _exampleRepository;

    public MyModelController(IExampleRepository exampleRepository)
    {
        _exampleRepository = exampleRepository;
    }

    [HttpGet] //RUN PERFECTLY ON IIS
    [Route("GetTestAll")]
    public IEnumerable<string> GetTest()
    {
        return new string[] { "value1", "value2", "value3", "value4" };
    }

    // GET: api/mymodel
    [HttpGet] //ERROR 404 ON IIS
    [Route("GetAll")]
    public IActionResult Get()
    {
        try
        {
             return Ok(_exampleRepository.GetAll().Select(x =>   Mapper.Map<MyModelViewModel>(x)));
        }
        catch (Exception exception)
        {
            //log exception or do anything with it
            return StatusCode((int)HttpStatusCode.InternalServerError);
        }
    }
}

試試看。

問題是，當我使用帶有安全整數的連接字符串並將其部署在工作站上的IIS 7上時，IIS會使用計算機的名稱，而不是將其用作Entityframework核心的標識符。
