NLOG與.net核心1.0 - LayoutRenderer無法找到

Question

這是非常相關的this question，但對於.NET的核心。我有一個用戶ID添加自定義佈局渲染器和它的工作，直到我在project.json爲「netcoreapp1.0」試圖從「net461」升級。當我這樣做，我不得不刪除NLog.Extensions，因爲它給了我這個錯誤：

Package NLog.Extensions 1.0.1 is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0). Package NLog.Extensions 1.0.1 supports: net45 (.NETFramework,Version=v4.5) 

一切編譯罰款，但在運行時，我得到的內部nlog.txt日誌文件中這個錯誤，並當然，它不會打我的自定義佈局渲染：

NLog.NLogConfigurationException: Error when setting property 'Layout' on NLog.Targets.DatabaseParameterInfo ---> System.ArgumentException: LayoutRenderer cannot be found: 'aspnet-user-id' 

是否有NLog.Extensions的替代品，還是我失去了一些東西？

下面是引用自project.json：

"NLog.Extensions.Logging": "1.0.0-rtm-alpha4", 
"NLog.Web.AspNetCore": "4.2.4" }, 

我把一切都在Startup.cs和NLog.config完全相同的配置，因爲它是不斷變化的框架之前的版本。如果發佈這些內容很有幫助，請告訴我，我會這樣做。 我很感激幫助。

編輯：新增project.json內容

Answer 1

假設你我們正在使用this NLog.Extensions package - 它不支持NETSTANDARD，所以你不能用netcoreapp1.0

升級爲使用它ASP.NET（到ASP.NET Core）不是微不足道的，看起來庫不再活躍。

幸運的是在NLog.Web.AspNetCore一個aspnet-user-identity，你都已經包括在內。

因此，與${aspnet-user-identity}

Answer 2

更換${aspnet-user-id}我不知道爲什麼，但是當我註釋掉的電子郵件目標和記錄器，自定義LayoutRenderer又開始工作。 僅供參考，以下是當前的nlog.config文件，其中註釋了電子郵件內容。

<?xml version="1.0" encoding="utf-8" ?> 
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    autoReload="true" 
    internalLogLevel="Warn" 
    internalLogFile="C:\temp\Logs\internal-nlog.txt"> 

<targets> 
<target xsi:type="Null" name="blackhole" /> 
<target name="database" xsi:type="Database" > 

    <connectionString> 
    Server=localhost;Database=LogDatabase;Trusted_Connection=True;MultipleActiveResultSets=true 
    </connectionString> 

    <commandText> 
    insert into dbo.Log (
     UserId, Application, LogDate, Level, Message, Exception 
    ) values (
     @User, @Application, @Logged, @Level, @Message, @Exception 
    ); 
    </commandText> 

    <parameter name="@application" layout="WebApplicationNameHere" /> 
    <parameter name="@logged" layout="${date}" /> 
    <parameter name="@level" layout="${level}" /> 
    <parameter name="@message" layout="${message}" /> 
    <parameter name="@user" layout="${aspnet-user-id} " /> <!-- This is a custom attribute, set in NLogHelper.cs--> 
    <parameter name="@exception" layout="${exception:tostring}" /> 
</target> 

<!--<target name="email" xsi:type="Mail" 
     subject="System Error" 
     body="Date-Time:${newline}${longdate}${newline}${newline}Machine:${newline}${machinename}${newline}${newline}User:${newline}${aspnet-user-identity} ${newline}${newline}Message:${newline}${message}" 
     to="first.last@domain.com" 
     from="support@mg.domain.com" 
     Encoding="UTF-8" 
     smtpUsername="postmaster@mg.domain.com" 
     enableSsl="true" 
     smtpPassword="passwordgoeshere" 
     smtpAuthentication="Basic" 
     smtpServer="smtp.mailgun.org" 
     smtpPort="587" 
/> --> 
</targets> 
<rules> 
<!--Skip Microsoft's verbose logging --> 
<logger name="Microsoft.*" minlevel="Trace" writeTo="blackhole" final="true" /> 
<logger name="*" minlevel="Trace" writeTo="database" /> 
<!--<logger name="*" level="Error" writeTo="email"/>--> 
</rules> 
<extensions> 
    <!--enable NLog.Web for ASP.NET Core--> 
    <add assembly="NLog.Web.AspNetCore"/> 
</extensions> 
</nlog> 

如果我取消了電子郵件的一部分，我得到下面的錯誤，不說對電子郵件部分是一個問題什麼。我甚至沒有嘗試過的電子郵件部分的唯一原因是因爲我意識到，我用來獲取電子郵件時，異常發生，現在我不這樣做，並試圖解決這個問題。

Answer 3

在根據節點添加您的NLog.config文件下列

<add assembly="NLog.Web.AspNetCore" /> 

希望這回答了你的quesetion。
