最新在将原来写的一些webSerivce转换为WebApi,直接就用了ASP.Net Core 2.0的框架,在使用中,发现的与原有的asp.net不同的地方,通过搜索已经慢慢解决,记录下来备用。
一、全局配置
在asp.net中,全局变更配置写在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,已经没有了web.config文件,查了一些资料,可以把全局变量配置写在appsetting.json文件中,如下所示:
1

{
"connectionStrings": {
"conn": "Data Source=localhost;Initial Catalog=helloworld;Integrated Security=True"
}
"appSettings": {
"app_key": "helloworld",
"app_secret": "1234567890abcdef"
}
}
|
这样一来,在程序中就可以对全局变量配置进行引用了。
使用appSetting.json,全局变量可以设置的更为复杂,具体的方法可以参考文后的参考文献。
二、记录日志
以前ASP.NET的时候,日志都是用Nlog进行记录,现在转换到了Core 2.0,也准备继续使用Nlog,在使用中,发现和以前的有也所不同。
首先,在Nuget中获取NLog.Web.AspNetCore包,
然后将startup.cs文件的代码进行修改
1
2
3
|
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
//修改为
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
|
并在Configure函数中,加上以下语句:
1
2
3
|
loggerFactory.AddNLog();
app.AddNLogWeb();
loggerFactory.ConfigureNLog(“nlog.config”);
|
记得要在文件头先引用using NLog.Web和using NLog.Extensions.Logging;
增加一个"Web配置文件",文件名为nlog.config,内容如下:

<? 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开始调用日志功能了。

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("数据库连接为:" + conn);
return;
}
}

以上这篇ASP.NET Core 2.0 WebApi全局配置及日志实例就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持服务器之家。
