[英]Serilog not writing to file with .NET Core 2.2
PS The code below works fine. PS下面的代码工作正常。 The problem was between the monitor and the chair.
问题出在显示器和椅子之间。 Answer by @jpgrassi sent me in the right direction to resolve it.
回答@jpgrassi让我朝着正确的方向解决它。
I have the following in program.cs: 我在program.cs中有以下内容:
public class Program {
public static void Main(string[] args) {
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseSerilog((ctx, config) => { config.ReadFrom.Configuration(ctx.Configuration); })
.UseStartup<Startup>();
}
And in appsettings.json: 在appsettings.json中:
{
"Serilog": {
"MinimumLevel": {
"Default": "Information",
"Override": {
"Default": "Information",
"Microsoft": "Information",
"System": "Information"
}
},
"WriteTo": [
{
"Name": "RollingFile",
"Args": {
"pathFormat": "log-{Date}.txt",
}
}
]
},
"AllowedHosts": "*"
}
In the controller, I write out a log _logger.LogWarning("foo");
在控制器中,我写出了一个log
_logger.LogWarning("foo");
, but the file is not written out anywhere, there aren't any error that I can see. ,但文件没有在任何地方写出,没有任何错误,我可以看到。
I've imported following packages from Nuget: Serilog, Serilog.AspNetCore, Serilog.Settings.Configuration, Serilog.Sinks.RollingFile. 我从Nuget导入了以下包:Serilog,Serilog.AspNetCore,Serilog.Settings.Configuration,Serilog.Sinks.RollingFile。
What am I missing? 我错过了什么?
I posted the original answer assuming the problem was the lack of the Using
property in the Serilog configuration. 我发布了原始答案,假设问题是Serilog配置中缺少
Using
属性。 I always had it in my projects and it was the only thing missing in OP's settings. 我总是在我的项目中使用它,这是OP设置中唯一缺少的东西。 But, after posting the answer I tried different configuration alternatives, including the same as in the question and the logs were still being produced.
但是,在发布答案之后,我尝试了不同的配置备选方案,包括与问题中相同的内容,并且仍在生成日志。 Reading more, I found out that the
Using
property is not necessary. 阅读更多,我发现不需要
Using
属性。 From the serilog-settings-configuration
package: 从
serilog-settings-configuration
包中:
(This package implements a convention using DependencyContext to find any package with Serilog anywhere in the name and pulls configuration methods from it, so the Using example above is redundant.) Source: https://github.com/serilog/serilog-settings-configuration
(这个包使用DependencyContext实现一个约定,在名称中的任何地方查找任何包含Serilog的包,并从中提取配置方法,因此上面的使用示例是多余的。)来源: https : //github.com/serilog/serilog-settings-组态
As it turns out (see question comments) the real issue was log file location and write permissions. 事实证明(参见问题评论)真正的问题是日志文件位置和写入权限。 Code-wise everything was already working.
代码方面的一切都已经有效了。
I'll keep the original answer here, as a matter of history, but its content does not actually fix anything, as nothing was broken in the first place. 作为历史问题,我会在这里保留原始答案,但其内容实际上并没有解决任何问题,因为首先没有任何内容被破坏。
Original answer: 原始答案:
I believe the problem is because you did not specify in your appsettings
to actually use the RollingFile
sink. 我认为问题是因为您没有在
appsettings
指定实际使用RollingFile
器。 I just quickly created a new app and it works: 我刚刚创建了一个新的应用程序,它的工作原理:
"Serilog": {
"Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.RollingFile" ],
"MinimumLevel": "Debug",
"WriteTo": [
{ "Name": "Console" },
{
"Name": "RollingFile",
"Args": { "pathFormat": "log-{Date}.txt" }
}
],
"Properties": {
"Application": "Sample"
}
}
Using the following NuGet packages: 使用以下NuGet包:
<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore.App" />
<PackageReference Include="Serilog.AspNetCore" Version="2.1.1" />
<PackageReference Include="Serilog.Settings.Configuration" Version="3.0.1" />
<PackageReference Include="Serilog.Sinks.Console" Version="3.1.1" />
<PackageReference Include="Serilog.Sinks.RollingFile" Version="3.3.0" />
</ItemGroup>
This logs to a file in the root directory of the app log-20190304.txt
. 这将记录到应用程序
log-20190304.txt
的根目录中的文件。
