Question

我正在使用.net Core 2.0.9和Serilog.Filters.Expressions 2.0.0。我将appsettings.json配置为写入数据库的日志表中。数据已成功记录在数据库中，但RequestPath属性始终为null：

"Serilog": {
        "MinimumLevel": {
            "Default": "Debug",
            "Override": {
                "Microsoft": "Debug"
            }
        },
        "WriteTo": [
            {
                "Name": "MSSqlServer",
                "Args": {
                    "connectionString": "myconnectionString",
                    "tableName": "Log"
                }
            }
        ],
        "WriteTo:Async": {
            "Name": "Async",
            "Args": {
                "configure": [
                    {
                        "Name": "File",
                        "Args": {
                            "path": "..\\output\\log.txt",
                            "rollingInterval": "Day"
                        }
                    }
                ]
            }
        },
        "Using": [ "Serilog.Settings.Configuration" ]
        "Filter": [
            {
                "Name": "ByIncludingOnly",
                "Args": {
                    "expression": "RequestPath like '%/api/book%'"
                }
            }
        ]
    },

但是我只想过滤和保存具有特定api路径的日志条目。在这种情况下，仅在RequestPath中包含api / user路径的条目。但是没有数据被保存了，我也没有日志错误，为什么？

这是我的工作步骤，请检查差异：

appsettings.json

"Serilog": {
    "MinimumLevel": "Information",
    "Override": {
    "Microsoft": "Critical"
    },
    "WriteTo": [
    {
        "Name": "MSSqlServer",
        "Args": {
        "connectionString": "Data Source=xx",
        "autoCreateSqlTable ": true,
        "tableName": "Logs",
        "autoCreateSqlTable": true,
        "columnOptionsSection": {
            "removeStandardColumns": [ "Properties" ],
            "customColumns": [
            {
                "ColumnName": "Release",
                "DataType": "varchar",
                "DataLength": 32
            },
            {
                "ColumnName": "RequestPath",
                "DataType": "varchar"
            },
            {
                "ColumnName": "ConnectionId",
                "DataType": "varchar"
            }
            ]
        }
        }

    },
    {
        "Name": "RollingFile",
        "Args": {
        "pathFormat": "Logs/app-{Date}.txt",
        "outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] {Message} {UserName} {ActionName}  {NewLine} {Exception}"
        }
    }
    ],
    "Using": [ "Serilog.Settings.Configuration" ],
    "Filter": [
    {
        "Name": "ByIncludingOnly",
        "Args": {
        "expression": "RequestPath like '%/api%'"
        }
    }
    ]
},

Startup.cs

    Log.Logger = new LoggerConfiguration()
                    .ReadFrom.ConfigurationSection(Configuration.GetSection("Serilog"))
                    .CreateLogger();

要检查serilog错误，请在下面添加代码：

    Log.Logger = new LoggerConfiguration()
                        .ReadFrom.ConfigurationSection(Configuration.GetSection("Serilog"))
                        .CreateLogger();
    Serilog.Debugging.SelfLog.Enable(msg =>
    {
        Debug.Print(msg);
        Debugger.Break();
    });

.Net核心扩展SeriLog过滤不起作用
