带有ASP.NET Core 1.0 MVC WebApi的EF Core 1.0错误404

Question

我有一个使用EF Core 1.0和ASP.NET Core 1.0 MVC WebApi的小型应用程序，在红est自托管方案（IIS Express）中运行良好。当我在IIS 7.0上发布时，调用方法使用EF时出现404错误核心，但是当我调用不使用EF核心的方法时，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.Extensions.Configuration.CommandLine": "1.0.0",

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

}}

在IIS服务器上将EF Core 1.0与ASP.NET Core 1.0 MVC WebApi一起使用的配置是什么。

谢谢你的帮助。 您将在此URL上找到一个应用程序，该应用程序回答了在IIS 7.0上被脉冲后将给出404错误的相同条件

在红est自托管方案（IIS Express）中运行良好。当我在IIS 7.0上发布时，出现404错误

它看起来像是与您的发布过程有关的问题，而不是与EF有关的问题，因为它在调试时起作用。

_exampleRepository.GetAll()或Automapper可能都需要一个已发布项目中缺少的文件。

在project.json文件中，您应该包括要在publish过程中复制的所有内容的列表。 例如我的看起来像这样

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

使用路由的最佳实践是在单独的路由属性中定义路由。

因此，您的代码应如下所示：

[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);
        }
    }
}

试试看。

问题是，当我使用带有安全整数的连接字符串并将其部署在工作站上的IIS 7上时，IIS会使用计算机的名称，而不是将其用作Entityframework核心的标识符。
