最新在將原來寫的一些webSerivce轉換為WebApi,直接就用了ASP.Net Core 2.0的框架,在使用中,發現的與原有的asp.net不同的地方,通過搜索已經慢慢解決,記錄下來備用。
一、全局配置
在asp.net中,全局變更配置寫在web.config中,如下所示

<? xml version = "1.0" ?> < configuration > < connectionStrings > < add name = "conn" connectionString = "Data Source=localhost;Initial Catalog=helloworld;Integrated Security=True" /> </ connectionStrings > < appSettings > < add key = "app_key" value = "helloworld" /> < add key = "app_secret" value = "1234567890abcdef" /> </ appSettings > </ configuration > |
在ASP.Net Core 2.0 WebApi中,已經沒有了web.config文件,查了一些資料,可以把全局變量配置寫在appsetting.json文件中,如下所示:

{ "connectionStrings": { "conn": "Data Source=localhost;Initial Catalog=helloworld;Integrated Security=True" } "appSettings": { "app_key": "helloworld", "app_secret": "1234567890abcdef" } } |
這樣一來,在程序中就可以對全局變量配置進行引用了。
使用appSetting.json,全局變量可以設置的更為復雜,具體的方法可以參考文后的參考文獻。
二、記錄日志
以前ASP.NET的時候,日志都是用Nlog進行記錄,現在轉換到了Core 2.0,也準備繼續使用Nlog,在使用中,發現和以前的有也所不同。
首先,在Nuget中獲取NLog.Web.AspNetCore包,
然后將startup.cs文件的代碼進行修改
1

3
|
public void Configure(IApplicationBuilder app, IHostingEnvironment env) //修改為 public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) |
并在Configure函數中,加上以下語句:
1
2
3
|
loggerFactory.AddNLog(); app.AddNLogWeb(); loggerFactory.ConfigureNLog(“nlog.config”); |
記得要在文件頭先引用using NLog.Web和using NLog.Extensions.Logging;
增加一個"Web配置文件",文件名為nlog.config,內容如下:

<? 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" > < targets > < target xsi:type = "File" name = "logfile" fileName = "${basedir}/logs/${shortdate}.log" keepFileOpen = "false" layout = "${longdate}|${callsite:fileName=True}|${uppercase:${level}}|${message} ${exception}" /> < target xsi:type = "File" name = "debugfile" fileName = "${basedir}/logs/${shortdate}_debug.log" keepFileOpen = "false" layout = "${longdate}|${callsite:fileName=True}|${uppercase:${level}}|${message} ${exception}" /> < target xsi:type = "File" name = "errfile" fileName = "${basedir}/logs/${shortdate}_error.log" keepFileOpen = "false" layout = "${longdate}|${callsite:fileName=True}|${uppercase:${level}}|${message} ${exception}" /> </ targets > < rules > < logger name = "*" level = "Debug" writeTo = "debugfile" /> < logger name = "*" level = "Error" writeTo = "errfile" /> < logger name = "*" minlevel = "Trace" writeTo = "logfile" /> </ rules > </ nlog > |
然后在程序中就可以開始調用日志功能了。
二個功能的DEMO代碼如下:

using System; using System.IO; using Microsoft.Extensions.Configuration; using NLog.Extensions.Logging; using NLog.Web; public class Program { public static IConfigurationRoot Configuration { get; set; } public static NLog.Logger log = NLog.LogManager.GetCurrentClassLogger(); public static void ConfigAndLog() { var builder = new ConfigurationBuilder() .SetBasePath(Directory.GetCurrentDirectory()) .AddJsonFile("appsettings.json"); Configuration = builder.Build(); string app_key = Configuration["appSettings:app_key"]; string coon = Configuration["connectionStrings:conn"]; log.Debug("數據庫連接為:" + conn); return; } } |
以上這篇ASP.NET Core 2.0 WebApi全局配置及日志實例就是小編分享給大家的全部內容了,希望能給大家一個參考,也希望大家多多支持服務器之家。
