Asp.Net Core 提供内置的日志,支持依赖注入,可以很方便地在控制器、Razor页面一级ViewComponent中使用。不过缺省提供的Provider只包括向控制台、Debug输出、Event Log等的输出,没有将日志记录到文件的缺省Provider,当然可以使用Log4Net等第三方日志插件,不过感觉太重了,最近发现了一个轻量级的日志插件,只需要一行代码的配置,就可以实现将日志输出到文件。首先,使用NuGet增加包 Serilog.Extensions.Logging.File到项目中,然后,在StartUp->Configure中增加如下设置
|
1 2 3 4 |
public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory) { loggerFactory.AddFile("Logs/PlatCore-{Date}.txt"); } |
配置就完成了,由于实现了ILogger接口,因此使用方法与缺省的完全相同。在项目的Logs文件夹中,可以查看输出的日志文件。 作者:寻找无名的特质 链接:https://www.jianshu.com/p/fb7f064223f7 来源:简书 著作权归作者所有。商业转载请联系作者获得授权,非商业转载请注明出处。
View Details最近项目有个新同事,每个API接口里返回的时间格式中都带T如:【2019-06-06T10:59:51.1860128+08:00】,其实这个主要是ASP.Net Core自带时间格式列化时间格式设置的,我们只需要替换序格式化时间格式就可以; 一、先建一个控制器测试:
|
1 2 3 4 5 6 7 8 9 10 |
public IActionResult Get() { UserInfo userInfo = new UserInfo() { Name = "lxsh", BirthDay = DateTime.Now }; return Ok(userInfo); } |
二、没有替换格式化时间之前效果: 三、可以在注入mvc服务的时候设置格式化参数,在Startup类的ConfigureServices方法中指定
|
1 2 3 4 |
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2).AddJsonOptions(options => { options.SerializerSettings.DateFormatString = "yyyy-MM-dd HH:mm:ss"; }); |
四、替换后的格式时间效果如下: from:https://www.cnblogs.com/lxshwyan/p/10983974.html
View Details【问题】网站 项目里经常用到DateTime类型变量,要求所有日期时间类型格式标准为“yyyy-MM-dd HH:mm:ss”,但默认Tostring格式为 yyyy-M-d H:m:s ,没有前置0, 需要修改 【分析】 1、修改代码里所有DateTime类型的Tostring为 ToString("yyyy-MM-dd HH:mm:ss"),不方便 2、找见统一的修改地方, Thread.CurrentThread.CurrentCulture = new CultureInfo("zh-CN", true) { DateTimeFormat = { ShortDatePattern = "yyyy-MM-dd", FullDateTimePattern = "yyyy-MM-dd HH:mm:ss" }; 发现不起作用 经分析DateTimeFormat 类的属性,发现 LongTimePattern 起作用 【结论】 增加 LongTimePattern 属性
|
1 2 3 |
Thread.CurrentThread.CurrentCulture = new CultureInfo("zh-CN", true) { DateTimeFormat = { ShortDatePattern = "yyyy-MM-dd", FullDateTimePattern = "yyyy-MM-dd HH:mm:ss", LongTimePattern ="HH:mm:ss"} }; |

View Details1、从微软下载net core https://download.visualstudio.microsoft.com/download/pr/dd164132-d4c4-4c1a-8233-a4fc7e157935/bffa5312d613cab1a14f0858f947a6fc/dotnet-runtime-2.1.11-linux-x64.tar.gz 2、将安装包上传至linux中 3、解压 tar -vxf dotnet-runtime-2.1.11-linux-x64.tar.gz 4、创建链接,使所有目录下都可以访问到dotnet命令(这里是解压后放在/home/dotnetcore目录下) ln -s /home/dotnetcore/dotnet /usr/local/bin 5、测试验证是否成功 任意目录下:dotnet --info 最后,使用dotnet+dll名称,测试软件是否可以运行,如果无法运行,则安装相应的软件包即可 参考: 1、.NET Core 指南:https://docs.microsoft.com/zh-cn/dotnet/core/ 2、net core下载中心:https://dotnet.microsoft.com/download/dotnet-core from:https://blog.csdn.net/dqcoffee/article/details/91353543
View Details在部署的时候,如果您不想在您的Linux服务器上安装.Net Core SDK,您可以只安装Runtime,接下来我们看看该如何安装运行时Runtime。 下载运行时文件 下载页面:https://www.microsoft.com/net/download/linux 先获取一下对应的下载链接,可以使用浏览器点击链接来获取具体文件的下载链接 获取完链接以后,就可以使用命令下获取和安装了 以Centos 7,Ubuntu 16.04为例安装ASP.Net Core 2.0.5的运行时:
|
1 2 3 4 5 |
wget -O dotnet-runtime.tar.gz https://download.microsoft.com/download/1/1/0/11046135-4207-40D3-A795-13ECEA741B32/dotnet-runtime-2.0.5-linux-x64.tar.gz wget -O aspnetcore-store.tar.gz https://download.microsoft.com/download/1/1/0/11046135-4207-40D3-A795-13ECEA741B32/aspnetcore-store-2.0.5-linux-x64.tar.gz mkdir dotnet tar zxf dotnet-runtime.tar.gz -C dotnet tar zxf aspnetcore-store.tar.gz -C dotnet |
还需要安装 libunwind Centos 7
|
1 |
yum update -y && yum install libunwind libicu -y |
Ubuntu 16.04
|
1 |
apt-get update -y && apt-get install libunwind-dev -y |
