Finally, name it Contracts.<\/strong> Do the same thing for the second project and name it LoggerService<\/strong>. Now that we have these projects in place, we need to reference them from our main project. To do that, navigate to the solution explorer. Then in the LoggerService<\/strong> project, right-click on Dependencies<\/strong> and choose the AddReference<\/strong> option. Under Projects, click Solution and check the Contracts<\/strong> project. Now, in the main project right click on Dependencies<\/strong> and then click on Add Reference<\/strong>. Check the LoggerService<\/strong> checkbox to import it. Since we have referenced the Contracts<\/strong> project through the LoggerService<\/strong>, it will be available in the main project too. Our logger service will contain four methods for logging our messages: To achieve this, we are going to create an interface named ILoggerManager<\/strong> inside the Contracts<\/strong> project containing those four method definitions. So, let\u2019s do that first: Before we implement this interface inside the LoggerService<\/strong> project, we need to install the NLog<\/strong> library in our LoggerService<\/strong> project. NLog<\/strong> is a logging platform for .NET which will help us create and log our messages. We are going to show two different ways of adding the NLog<\/strong> library to our project. 1.In the LoggerService<\/strong> project, right-click on the Dependencies<\/strong> and choose Manage NuGet Packages. After the NuGet Package Manager<\/strong> window appears, just follow these steps: 2.From the View menu, choose Other Windows and then click on the Package Manager Console<\/strong>. After the console appears, type: Install-Package NLog.Extensions.Logging -Version 1.6.5 After a couple of seconds, NLog<\/strong> is up and running in our application. In the LoggerService<\/strong> project, we are going to create a new class: LoggerManager<\/strong>. Now let\u2019s have it implement the ILoggerManager<\/strong> interface we previously defined: As you can see, our methods are just wrappers around NLog\u2019s methods. Both ILogger<\/strong> and LogManager<\/strong> are part of the NLog<\/strong> namespace. Now, we need to configure it and inject it into the Startup class in the ConfigureServices<\/strong> method. NLog needs to have information about where to put log files on the file system, what the name of these files will be, and what is the minimum level of logging that we want. We are going to define all these constants in a text file in the main project and name it nlog.config<\/strong>. You'll need to change the path of the internal log<\/strong> and filename<\/strong> parameters to your own paths. Setting up the configuration for a logger service is quite easy. First, we need to update the constructor of the Startup<\/strong> class: Basically, we are using NLog\u2019s LogManager<\/strong> static class with the LoadConfiguration method to provide a path to the configuration file. The next thing we need to do is to add the logger service inside the .NET Core\u2019s IOC container. There are three ways to do that: So, let\u2019s add a new method in the ServiceExtensions<\/strong> class: And after that, we need to modify the ConfigureServices method to include our newly created extension method: Every time we want to use a logger service, all we need to do is to inject it into the constructor of the class that needs it. .NET Core will resolve that service and the logging features will be available. This type of injecting a class is called Dependency Injection and it is built into .NET Core. Let\u2019s learn a bit more about it. What is Dependency Injection (DI) exactly and what is IoC (Inversion of Control)? Dependency injection is a technique we use to achieve the decoupling of objects and their dependencies. It means that rather than instantiating an object explicitly in a class every time we need it, we can instantiate it once and then send it to the class. This is often done through a constructor. The specific approach we utilize is also known as the Constructor Injection<\/strong>. In a system that is designed around DI, you may find many classes requesting their dependencies via their constructors. In this case, it is helpful to have a class that manages and provides dependencies to classes through the constructor. These classes are referred to as containers or more specifically, Inversion of Control containers. An IoC container is essentially a factory that is responsible for providing instances of the types that are requested from it. To test our logger service, we are going to use the default WeatherForecastController<\/strong>. You can find it in the main project in the Controllers folder. It comes with the ASP.NET Core Web API template. In the Solution Explorer, we are going to open the Controllers folder and locate the WeatherForecastController<\/strong> class. Let\u2019s modify it: Now let\u2019s start the application and browse to Tip: If you are using Windows 8 and having trouble starting this application on https:\/\/localhost:5001<\/a><\/a><\/a>..., you have to add a parameter to the appsetings.Development.json file: As a result, you will see an array of two strings. Now go to the folder that you have specified in the nlog.config<\/strong> file, and check out the result. You should see two folders: the internal_logs<\/strong> folder and the logs<\/strong> folder. Inside the logs<\/strong> folder, you should find a file with the following logs: That\u2019s all we need to do to configure our logger for now. We\u2019ll add some messages to our code along with the new features. 2 Configuring a Logging Service Why does logging messages matter so much during application development? While our application is in the development stage, it’s easy to debug the code and find out what happened. But debugging in a production environment is not that easy. \u4e3a\u4ec0\u4e48\u5728\u5e94\u7528\u7a0b\u5e8f\u5f00\u53d1\u8fc7\u7a0b\u4e2d\u8bb0\u5f55\u6d88\u606f\u5982\u6b64\u91cd\u8981\uff1f\u867d\u7136\u6211\u4eec\u7684\u5e94\u7528\u7a0b\u5e8f\u5904\u4e8e\u5f00\u53d1\u9636\u6bb5\uff0c\u4f46\u5f88\u5bb9\u6613\u8c03\u8bd5\u4ee3\u7801\u5e76\u627e\u51fa\u53d1\u751f\u4e86\u4ec0\u4e48\u3002\u4f46\u662f\u5728\u751f\u4ea7\u73af\u5883\u4e2d\u8fdb\u884c\u8c03\u8bd5\u5e76\u4e0d\u5bb9\u6613\u3002\u200c\u200c That’s why log messages are a great way to find […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[23],"class_list":["post-138","post","type-post","status-publish","format-standard","hentry","category-csharp","tag-ultimate-asp-net-core-web-api"],"_links":{"self":[{"href":"https:\/\/diji.net\/index.php?rest_route=\/wp\/v2\/posts\/138","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/diji.net\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/diji.net\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/diji.net\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/diji.net\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=138"}],"version-history":[{"count":0,"href":"https:\/\/diji.net\/index.php?rest_route=\/wp\/v2\/posts\/138\/revisions"}],"wp:attachment":[{"href":"https:\/\/diji.net\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=138"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/diji.net\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=138"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/diji.net\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=138"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
