停止 Serilog 在 ASP.NET Core MVC 中记录 HTTP GET

Question

Serilog 已成功记录日志，但自动记录 HTTP GET api 调用。如何抑制HTTP调用？

我在日志文件中有这样的条目：

2024-10-25 06:24:10.040 -04:00 [INF] HTTP GET / responded 200 in 6107.3816 ms

program.cs

：

builder.Host.UseSerilog((context, configuration) =>
{
    var requestLoggingOptions = new RequestLoggingOptions();
    configuration.ReadFrom.Configuration(context.Configuration);
});

appsettings.json

：

"Serilog": {
    "Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],
    "MinimumLevel": {
        "Default": "Debug",
        "Override": {
            "Microsoft": "Warning", //If the error starts with Microsoft, it needs to be a warning level
            "Microsoft.AspNetCore": "Warning", 
            "System": "Warning" //If the error starts with System, it needs to be a warning level
            "System.Net.Http.HttpClient": "Warning"  //probably not necessary because of the line above
        }
    },
    "WriteTo": [ ... suppressed ...
    ],

    "Filter": [
        {
            "Name": "ByExcludingOnly",
            "Args": {
                "expression": "e.Request.Method == \"GET\"",
            }
        }
    ]
},

我尝试添加其他最低级别和过滤器，但仍然创建 HTTP

GET

记录。

在您的

Program.cs

或类似位置，您将接到电话

UseSerilogRequestLogging()

。解决此问题的一种方法是直接为 API 请求分配较低的日志记录级别：

app.UseSerilogRequestLogging(options =>
    options.GetLevel = (HttpContext ctx, double elapsed, Exception? ex) =>
        ex != null
            ? LogEventLevel.Error
            : ctx.Request.Method == "GET"
                ? LogEventLevel.Debug
                : ctx.Response.StatusCode > 499
                    ? LogEventLevel.Error
                    : LogEventLevel.Information);

（Serilog.Expressions 是另一个不错的选择，正如上面评论者提到的。）
