尝试使用 appsettings.json 配置 Serilog 电子邮件接收器以与 Gmail 一起使用

Trying to Configure Serilog Email sink with appsettings.json to work with Gmail

在 POC 中,我让 Smtp 客户端通过 Gmail 发送电子邮件,所以我知道我关于连接到 Gmail 的 SMTP 服务器的信息是正确的。我现在正尝试通过 appsettings.json 配置 Serilog 以通过 Gmail 发送我的日志条目。我需要能够针对不同的环境对其进行不同的配置。我目前将它设置为 Verbose,这样我就可以得到任何东西……以后就不会这样了。除了我的文件日志条目,我什么都没有得到。我使用本地网络 SMTP 服务器进行了此操作,该服务器采用默认设置且没有网络凭据。现在我需要设置端口、ssl 和网络凭据才能通过 Gmail 发送。

这是我的 WriteTo 部分...

 "WriteTo": [      
      {
        "Name": "RollingFile",
        "Args": {
          "pathFormat": "C:/log/log-{Date}.json",
          "formatter": "Serilog.Formatting.Json.JsonFormatter, Serilog",
          "fileSizeLimitBytes": 2147483648,
          "retainedFileCountLimit": 180,
          "restrictedToMinimumLevel": "Verbose"
        }
      },
      {
        "Name": "Email",
        "Args": {
          "connectionInfo": {
            "FromEmail": "{email address}",
            "ToEmail": "{email address}",
            "MailServer": "smtp.gmail.com",
            "EmailSubject": "Fatal Error",
            "NetworkCredentials": {
              "userName": "{gmailuser}@gmail.com",
              "password": "{gmailPassword}"
            },
            "Port": 587,
            "EnableSsl" : true
          },          
          "restrictedToMinimumLevel": "Verbose"
        }
      }
    ]
  },

感谢任何帮助。

将您的端口号更改为 465,它应该适合您。以下是有关 gmail smtp 设置的一些信息:https://www.lifewire.com/what-are-the-gmail-smtp-settings-1170854

我使用的是 Core 2.0,无法让 serilog 电子邮件接收器与 appsettings.json 文件一起使用,但我确实通过在 program.cs 文件中设置配置使其正常工作,例如所以:

var logger = new LoggerConfiguration()
.WriteTo.RollingFile(
    pathFormat: "..\..\log\AppLog.Web-{Date}.txt",
    outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] [{SourceContext}] [{EventId}] {Message}{NewLine}{Exception}"
)
.WriteTo.Email(new EmailConnectionInfo
    {
        FromEmail = appConfigs.Logger.EmailSettings.FromAddress,
        ToEmail = appConfigs.Logger.EmailSettings.ToAddress,
        MailServer = "smtp.gmail.com",
        NetworkCredentials = new NetworkCredential {
            UserName = appConfigs.Logger.EmailSettings.Username,
            Password = appConfigs.Logger.EmailSettings.Password
        },
        EnableSsl = true,
        Port = 465,
        EmailSubject = appConfigs.Logger.EmailSettings.EmailSubject
    },
    outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] {Message}{NewLine}{Exception}",
    batchPostingLimit: 10
    , restrictedToMinimumLevel: Serilog.Events.LogEventLevel.Error
)
.CreateLogger();
如果您需要 NetworkCredentials,

appsettings 不适用于 Serilog.Synk.Email。它将引发此异常:System.InvalidOperationException: 'Cannot create instance of type 'System.Net.ICredentialsByHost' because it is either abstract or an interface.'。使用 @rcf113 答案使事情正常进行。

要使用您的 gmail 帐户, 您必须:

  1. EnableSsl: 真
  2. 端口:465
  3. 创建app password

要使 appsettings 正常工作,您必须想出一个自定义实现。此解决方案来自@adriangutowski github answer

创建自定义静态扩展 class 为 ICredentialsByHost 属性

实例化 NetworkCredential
    namespace MyWebApi.Extensions
    {
    
        public static class SerilogCustomEmailExtension
        {
            const string DefaultOutputTemplate = "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] {Message}{NewLine}{Exception}";
    
            public static LoggerConfiguration CustomEmail(
                this LoggerSinkConfiguration loggerConfiguration,
                CustomEmailConnectionInfo connectionInfo,
                string outputTemplate = DefaultOutputTemplate,
                LogEventLevel restrictedToMinimumLevel = LevelAlias.Minimum
            )
            {
                return loggerConfiguration.Email(
                    connectionInfo,
                    outputTemplate,
                    restrictedToMinimumLevel
                );
            }
    
            public class CustomEmailConnectionInfo : EmailConnectionInfo
            {
                public CustomEmailConnectionInfo()
                {
                    NetworkCredentials = new NetworkCredential();
                }
            }
        }
    }

然后使用您的程序集名称(不是命名空间)配置您的应用设置 Serilog.Using 并向 Serilog.WriteTo[]

添加一个新条目
    
      "Serilog": {
        "Using": [ "Serilog.Sinks.Email", "MyWebApi" ],
        "MinimumLevel": "Error",
        "WriteTo": [
          {
            "Name": "CustomEmail",
            "Args": {
              "ConnectionInfo": {
                "NetworkCredentials": {
                  "UserName": "aaaaaaaaaaaaaa@gmail.com",
                  "Password": "aaaaaaaaaaaaaa"
                },
                "FromEmail": "aaaaaaaaaaaaaa@gmail.com",
                "MailServer": "smtp.gmail.com",
                "EmailSubject": "[{Level}] Log Email",
                "Port": "465",
                "IsBodyHtml": false,
                "EnableSsl": true,
                "ToEmail": "aaaaaaaaaaaaaa@gmail.com"
              },
              "RestrictedToMinimumLevel": "Error",
              "OutputTemplate": "{Timestamp:yyyy-MM-dd HH:mm} [{Level}] {Message}{NewLine}{Exception}"
            }
          }
        ]
      }

此配置使用

效果很好
  • 点网核心 6
  • Serilog.Sinks.Email 版本="2.4.0"
