问题
As part of my application I have a .Net Core API project. Unlike most cases where this project would run as its own process, I have the API run in a thread, among others, in a single process. Also for my project, I have implemented a custom logging system to suit my needs. However, I have come across a slight problem. Every time I run my program, once the API starts, this message is printed to the console:
Hosting environment: Production
Content root path: C:\Users\Path\To\Code
Now listening on: http://*:8000
Application started. Press Ctrl+C to shut down.
I would like to disable this message as there is no need for it, and it clutters up the otherwise well organized console log. I have a screenshot below so you know exactly what I'm talking about:
I have already disabled all other logging for the mvc (removed ILoggerFactory from ConfigureServices and set all logging to "None" in appsettings.json).
How do I go about disabling/suppressing this message?
回答1:
You could also do this:
var host = BuildWebHost(args);
host.Start();
host.WaitForShutdown();
This will bypass the Console.WriteLine()s.
回答2:
In ASP.NET Core 2.1, use the SuppressStatusMessages method on the WebHostBuilder.
WebHost.CreateDefaultBuilder()
.UseStartup<Startup>()
.SuppressStatusMessages(true);

These messages can be disabled in 2 ways (beside already mentioned console settings):
1) You can disable them with Environment variable:
"ASPNETCORE_SUPPRESSSTATUSMESSAGES": "true"
2) Or through code (in Program.cs):
WebHost.CreateDefaultBuilder(args)
.UseSetting(WebHostDefaults.SuppressStatusMessagesKey, "True")
or
WebHost.CreateDefaultBuilder(args)
.SuppressStatusMessages(true);

Removing logger factory won't help, because it is Console.WriteLine() (Ref : Github issue comment) . You need to suppress the Console.WriteLine outputs. In the Main method, write code like this. This will ignore the Console.WriteLine outputs.
public static void Main(string[] args)
{
Console.SetOut(new StreamWriter(Stream.Null));
BuildWebHost(args).Run();
}
