大家好我怎样才能得到这个输出
{
"@t": "2020-11-03T16:40:21.6133998Z",

"ConnectionId": "0HM402S7EC249"
}
但是当我调用我的控制器时，我看到并运行应用程序，我看到
这就是我设置 Serilog 的方式，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);
}
}

Serilog 项目提供了三种 JSON 格式化程序：
Serilog.Formatting.Json.JsonFormatter- 这是 Serilog 包中附带的历史默认值。它生成日志事件的完整呈现并支持一些配置选项。Serilog.Formatting.Compact.CompactJsonFormatter- Serilog.Formatting.Compact 中提供了更新、更节省空间的 JSON 格式化程序。Serilog.Formatting.Compact.RenderedCompactJsonFormatter- 也在 Serilog.Formatting.Compact 中提供，该格式化程序将消息模板预渲染为文本。您可以参考以下步骤来自Serilog.Formatting.Compact定义 Serilog 输出：
Serilog.AspNetCore通过 Nuget安装。
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>();
});
}
请记住添加以下参考：
using Serilog;
using Serilog.Events;
using Serilog.Formatting.Compact;
根据您的代码，您似乎想记录请求和响应信息，如果是这样的话，您也可以创建一个SerilogRequestLogger中间件。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);
}
}
}
SerilogRequestLogger在方法中配置中间件Configure：
app.UseMiddleware<SerilogRequestLogger>();
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);
结果是这样的：
{"@t":"2020-11-04T14:19:23.2065796Z","@mt":"在 {Created} 上创建了 {@User}","User":{"Id":"1001","年龄":0,"用户名":"亚当","NormalizedUserName":null,"电子邮件":null,"NormalizedEmail":null,"EmailConfirmed":false,"PasswordHash":null,"SecurityStamp":"11/ 4/2020 10:19:23 PM"，"ConcurrencyStamp"："ca564733-9524-446f-8103-dd211cf8b44c"，"电话号码"：空，"电话号码确认"：假，"TwoFactorEnabled"：假，"LockoutEnd"：空,"LockoutEnabled":false,"AccessFailedCount":0,"$type":"WebApplication2User"},"已创建":"2020-11-04T22:19:23.2060830+08:00","用户名":null," RequestId":"80000080-0005-fd00-b63f-84710c7967bb","RequestPath":"/Home/Privacy","SpanId":"|e29bfdb0-4bd9f6a34acb24d8。","TraceId":"e29bfdb0-4bd9f6a34acb24d8","Par实体ID “：”“}
