}
but when i invoke my controller i see and run application i see that但是当我调用我的控制器时,我看到并运行了应用程序,我看到了
thats class how i setting my Serilog,what i do wrong这就是我如何设置我的 Serilog,我做错了什么
public class LogConfig
{
public static void Configure()
{
Log.Logger = new LoggerConfiguration()
.WriteTo.Console(new RenderedCompactJsonFormatter())
.CreateLogger();
}
public static void EnrichFromRequest(IDiagnosticContext diagnosticContext, HttpContext httpContext)
{
diagnosticContext.Set("RequestScheme", httpContext.Request.Host.Value);
diagnosticContext.Set("Headers", httpContext.Request.Scheme);
}
}

thanks in advance :)提前致谢 :)
There are three JSON formatters provided by the Serilog project: Serilog 项目提供了三种 JSON 格式化程序:
Serilog.Formatting.Json.JsonFormatter
- This is the historical default shipped in the Serilog package. Serilog.Formatting.Json.JsonFormatter
- 这是 Serilog 包中提供的历史默认值。 It produces a complete rendering of the log event and supports a few configuration options.Serilog.Formatting.Compact.CompactJsonFormatter
- A newer, more space-efficient JSON formatter shipped in Serilog.Formatting.Compact. Serilog.Formatting.Compact.CompactJsonFormatter
- 在Serilog.Formatting.Compact.CompactJsonFormatter
提供的更新、更节省空间的 JSON 格式化程序.Serilog.Formatting.Compact.RenderedCompactJsonFormatter
- Also shipped in Serilog.Formatting.Compact, this formatter pre-renders message templates into text. Serilog.Formatting.Compact.RenderedCompactJsonFormatter
- 同样在 Serilog.Formatting.Compact 中提供,此格式化程序将消息模板预渲染为文本。 You could refer the following steps and use Serilog.Formatting.Compact
to customize Serilog output:您可以参考以下步骤并使用
Serilog.Formatting.Compact
自定义 Serilog 输出:
Install Serilog.AspNetCore
via Nuget.安装
Serilog.AspNetCore
通过的NuGet。
Configure to use Serilog
:配置使用
Serilog
:
public class Program { public static int Main(string[] args) { // CreateHostBuilder(args).Build().Run(); Log.Logger = new LoggerConfiguration() .MinimumLevel.Debug() .MinimumLevel.Override("Microsoft", LogEventLevel.Information) .Enrich.FromLogContext() .WriteTo.File(new CompactJsonFormatter(), "log20201104.json") .CreateLogger(); try { Log.Information("Starting web host"); CreateHostBuilder(args).Build().Run(); return 0; } catch (Exception ex) { Log.Fatal(ex, "Host terminated unexpectedly"); return 1; } finally { Log.CloseAndFlush(); } } public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .UseSerilog() .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); }); }
Remember to add the following reference:记得添加以下引用:
using Serilog; using Serilog.Events; using Serilog.Formatting.Compact;
According to your code, it seems that you want to log the request and response information, if that is the case, you could also create a SerilogRequestLogger
Middleware.根据您的代码,您似乎想记录请求和响应信息,如果是这种情况,您还可以创建一个
SerilogRequestLogger
中间件。 Like this:像这样:
public class SerilogRequestLogger { readonly RequestDelegate _next; public SerilogRequestLogger(RequestDelegate next) { if (next == null) throw new ArgumentNullException(nameof(next)); _next = next; } public async Task Invoke(HttpContext httpContext) { if (httpContext == null) throw new ArgumentNullException(nameof(httpContext)); // Push the user name into the log context so that it is included in all log entries LogContext.PushProperty("UserName", httpContext.User.Identity.Name); // Getting the request body is a little tricky because it's a stream // So, we need to read the stream and then rewind it back to the beginning string requestBody = ""; HttpRequestRewindExtensions.EnableBuffering(httpContext.Request); Stream body = httpContext.Request.Body; byte[] buffer = new byte[Convert.ToInt32(httpContext.Request.ContentLength)]; await httpContext.Request.Body.ReadAsync(buffer, 0, buffer.Length); requestBody = Encoding.UTF8.GetString(buffer); body.Seek(0, SeekOrigin.Begin); httpContext.Request.Body = body; Log.ForContext("RequestHeaders", httpContext.Request.Headers.ToDictionary(h => h.Key, h => h.Value.ToString()), destructureObjects: true) .ForContext("RequestBody", requestBody) .Debug("Request information {RequestMethod} {RequestPath} information", httpContext.Request.Method, httpContext.Request.Path); Log.Information(string.Format("Request Body: {0} ", requestBody)); var exampleUser = new WebApplication2User { Id = "1001", UserName = "Adam", SecurityStamp = DateTime.Now.ToString() }; Log.Information("Created {@User} on {Created}", exampleUser, DateTime.Now); // The reponse body is also a stream so we need to: // - hold a reference to the original response body stream // - re-point the response body to a new memory stream // - read the response body after the request is handled into our memory stream // - copy the response in the memory stream out to the original response stream using (var responseBodyMemoryStream = new MemoryStream()) { var originalResponseBodyReference = httpContext.Response.Body; httpContext.Response.Body = responseBodyMemoryStream; await _next(httpContext); httpContext.Response.Body.Seek(0, SeekOrigin.Begin); var responseBody = await new StreamReader(httpContext.Response.Body).ReadToEndAsync(); httpContext.Response.Body.Seek(0, SeekOrigin.Begin); Log.ForContext("RequestBody", requestBody) .ForContext("ResponseBody", responseBody) .Debug("Response information {RequestMethod} {RequestPath} {statusCode}", httpContext.Request.Method, httpContext.Request.Path, httpContext.Response.StatusCode); await responseBodyMemoryStream.CopyToAsync(originalResponseBodyReference); } } }
Configure the SerilogRequestLogger
Middleware in the Configure
method:在
Configure
方法中配置SerilogRequestLogger
中间件:
app.UseMiddleware<SerilogRequestLogger>();
Then, you could use the following code to log information:然后,您可以使用以下代码来记录信息:
var exampleUser = new WebApplication2User { Id = "1001", UserName = "Adam", SecurityStamp = DateTime.Now.ToString() };
Log.Information("Created {@User} on {Created}", exampleUser, DateTime.Now);
the result like this:结果是这样的:
{"@t":"2020-11-04T14:19:23.2065796Z","@mt":"Created {@User} on {Created}","User":{"Id":"1001","Age":0,"UserName":"Adam","NormalizedUserName":null,"Email":null,"NormalizedEmail":null,"EmailConfirmed":false,"PasswordHash":null,"SecurityStamp":"11/4/2020 10:19:23 PM","ConcurrencyStamp":"ca564733-9524-446f-8103-dd211cf8b44c","PhoneNumber":null,"PhoneNumberConfirmed":false,"TwoFactorEnabled":false,"LockoutEnd":null,"LockoutEnabled":false,"AccessFailedCount":0,"$type":"WebApplication2User"},"Created":"2020-11-04T22:19:23.2060830+08:00","UserName":null,"RequestId":"80000080-0005-fd00-b63f-84710c7967bb","RequestPath":"/Home/Privacy","SpanId":"|e29bfdb0-4bd9f6a34acb24d8.","TraceId":"e29bfdb0-4bd9f6a34acb24d8","ParentId":""}
{"@t":"2020-11-04T14:19:23.2065796Z","@mt":"在 {Created} 上创建了 {@User}","User":{"Id":"1001"," Age":0,"UserName":"Adam","NormalizedUserName":null,"Email":null,"NormalizedEmail":null,"EmailConfirmed":false,"PasswordHash":null,"SecurityStamp":"11/ 4/2020 10:19:23 PM","ConcurrencyStamp":"ca564733-9524-446f-8103-dd211cf8b44c","PhoneNumber":null,"PhoneNumberConfirmed":false,"TwoFactorEnabled":false,"LockoutEnd" ,"LockoutEnabled":false,"AccessFailedCount":0,"$type":"WebApplication2User"},"Created":"2020-11-04T22:19:23.2060830+08:00","UserName":null," RequestId":"80000080-0005-fd00-b63f-84710c7967bb","RequestPath":"/Home/Privacy","SpanId":"|e29bfdb0-4bd9f6a34acb24d8.","TraceId"bf4b4db4d8d8c","TraceIdb4db4dbf9dbef9 ":""}
