【问题描述】：

我需要在 EF Core 中记录 sql 命令（选择、更新、删除、插入）。我有下一个认识：

public class CustomLoggerProvider : ILoggerProvider
{
    public ILogger CreateLogger(string categoryName)
    {
        if (string.Equals(categoryName, DbLoggerCategory.Database.Command.Name))
        {
            return new CustomLogger();
        }

        return NullLogger.Instance;
    }

    public void Dispose() { }

    private class CustomLogger : ILogger
    {
        public IDisposable BeginScope<TState>(TState state) => null;

        public bool IsEnabled(LogLevel logLevel) => true;

        public void Log<TState>(LogLevel logLevel, EventId eventId, TState state, Exception exception, Func<TState, Exception, string> formatter)
        {
            var log = formatter(state, exception);
            AppLogger.Log(log);
        }
    }
}

...
dbcontext.GetService<ILoggerFactory>().AddProvider(new CustomLoggerProvider());

如果是 INSERT 命令，我会得到一组日志。其中一个是下一个：

"Executing DbCommand [Parameters=[@p0='?' (Size = 128), @p1='?' (DbType = DateTimeOffset), @p2='?' (Size = 128), @p3='?' (Size = 128), @p4='?' (Size = 128) (DbType = Binary), @p5='?' (DbType = DateTimeOffset), @p6='?' (DbType = DateTimeOffset)], CommandType='Text', CommandTimeout='30']\r\nSET NOCOUNT ON;\r\nINSERT INTO [someSchema].[SomeTable] ([ID], [Column1], [Column2], [Column3], [Column4], [Column5], [Column6])\r\nVALUES (@p0, @p1, @p2, @p3, @p4, @p5, @p6);"

如您所见，@p0='?'或 @p0 而不是参数值。有办法解决吗？

【解决方案1】：

您需要启用Sensitive Logging

services.AddDbContextPool<MyDbContext>(builder =>
{
    ....
    builder.EnableSensitiveDataLogging(true);
});

或

public class MyDbContext : DbContext
{

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    { 
        optionsBuilder.EnableSensitiveDataLogging();
        base.OnConfiguring(optionsBuilder);
    }

}
