小编Nic*_*liu的帖子

我有这个实体：

    public int Id { get; private set; }
    public string Name { get; private set; }
    public Behavior Behavior { get; private set; }

    public Product(int id, string name, Behavior behavior)
    {
        Id = id;
        Name = name;
        Behavior = behavior;
    }

在启动方法中，我正在注册 EdmModel ：

        var builder = new ODataConventionModelBuilder();
        var entitySet = builder.EntitySet<Product>("Products");
        entitySet.EntityType.HasKey(x => x.Id);


        var model = builder.GetEdmModel();



        app.UseMvc(route =>
        {
            route.Select().Filter().Expand().OrderBy().Count().MaxTop(null);
            route.MapODataServiceRoute("odata", null, model);
            route.EnableDependencyInjection();
        }
        );

当我运行我的应用程序时，会发生此异常：

         InvalidOperationException: The entity 'Product' does not have …

我在Setup.cs 文件中有这段代码

      protected override MvxLogProviderType GetDefaultLogProviderType() =>                                                  
                                                 MvxLogProviderType.Serilog;

      protected override IMvxLogProvider CreateLogProvider()
      {
          Log.Logger = new LoggerConfiguration()
            .MinimumLevel.Verbose()
            .WriteTo.Logger(config => config
                .MinimumLevel.Verbose()
                .WriteTo.File("C:\\log.txt"))
            .CreateLogger();
        return base.CreateLogProvider();
    }

在 ViewModel 中，我有：通过 IoC 初始化的私有只读 IMvxLog _log。

当我调用 _log.Error("Some error") 时，log.txt 文件中没有写入任何内容。

当我尝试将新集合添加到数据库时,我收到此错误:

Failed to create collection 'Products'.

这是一个本地模拟器,这个地区有什么样的高级别？

我正在尝试实现我自己的日志提供程序。

Setup.cs 包含：

protected override MvxLogProviderType GetDefaultLogProviderType() => MvxLogProviderType.None;

protected override IMvxLogProvider CreateLogProvider()
{
    var logger = new Logger();
    return base.CreateLogProvider();
}

记录器

public class Logger : IMvxLog
{
    public bool Log(MvxLogLevel logLevel, Func<string> messageFunc, Exception exception = null, params object[] formatParameters)
    {
        var client = new HttpClient();
        var url = new Uri("https://jsonplaceholder.typicode.com/posts/1");
        client.PostAsync(url,null);
        return true;
    }
}

当 IoC 尝试解决依赖关系时，它会与 ViewModel 构造函数一起崩溃。

错误信息：

创建 eOrder.ViewModel.ActivitiesViewModel 时无法解析类型为 IMvxLog 的参数日志的参数

也许我不需要覆盖MvxLogProviderType.None？
