Question

原始问题正在编辑中。

编辑：所以我想出了问题。该应用程序的数据库已设置为副本集，而这正是这里所缺少的。我遵循了文章https://docs.mongodb.com/manual/tutorial/deploy-replica-set-for-testing/中提到的所有步骤但现在无法设置副本集

 [LogicalSessionCacheReap] Sessions collection is not set up; waiting until next sessions reap interval: config.system.sessions does not exist
2019-08-12T09:32:27.102+0530 I CONTROL  [LogicalSessionCacheReap] Sessions collection is not set up; waiting until next sessions reap interval: config.system.sessions does not exist
2019-08-12T09:32:27.103+0530 I CONTROL  [LogicalSessionCacheRefresh] Sessions collection is not set up; waiting until next sessions refresh interval: Replication has not yet been configured

这是我在运行命令时得到的

mongod --replSet rsSpeQue --port 27017 --bind_ip localhost --dbpath \SpeQueRS\rsSpeQue1 --smallfiles --oplogSize 128

设置在端口27017上设置的副本。命令输出> db.runCommand（“ getCmdLineOpts”）

{
        "argv" : [
                "C:\\Program Files\\MongoDB\\Server\\4.0\\bin\\mongod.exe",
                "--config",
                "C:\\Program Files\\MongoDB\\Server\\4.0\\bin\\mongod.cfg",
                "--service"
        ],
        "parsed" : {
                "config" : "C:\\Program Files\\MongoDB\\Server\\4.0\\bin\\mongod.cfg",
                "net" : {
                        "bindIp" : "127.0.0.1",
                        "port" : 27017
                },
                "service" : true,
                "storage" : {
                        "dbPath" : "C:\\Program Files\\MongoDB\\Server\\4.0\\data",
                        "journal" : {
                                "enabled" : true
                        }
                },
                "systemLog" : {
                        "destination" : "file",
                        "logAppend" : true,
                        "path" : "C:\\Program Files\\MongoDB\\Server\\4.0\\log\\mongod.log"
                }
        },
        "ok" : 1
}

基本上，没有设置副本集。我在这里想念什么？

由于您没有提供任何.NET Core 2.2应用程序中安装的C＃代码和nu-gets，因此我在此处给出一个通用答案。尝试以下方法，让我知道是否可以解决问题：

为MongoDB更改appsettings.Development.json中的connectionString，如下所示：

  WITH XMLNAMESPACES(DEFAULT'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition')
SELECT c.ItemID as ReportID,
       c.Name as ReportName,
       c.path as ReportPath,
       CAST(CONVERT( xml, CONVERT(varbinary(MAX), Content)) AS varchar(MAX)) as ReportContent,
       CONVERT( xml, CONVERT(varbinary(MAX), Content) ).value('(/Report/DataSets/DataSet/Query/CommandText/text())[1]','varchar(1000)') as ReportQuery
  INTO #RSTemp
  FROM [dbo].[Catalog] c
 WHERE Content IS NOT NULL AND type =2
    GO

SELECT * 
  FROM #RSTemp
 WHERE ReportContent LIKE '%Any SQL command, table name or comment I want to search for!%'

}

确保您已安装以下Nuget（并非强制要求全部安装，但便于以后操作）

"ConnectionStrings": {
"DefaultConnection": "mongodb://localhost:27017?connect=replicaSet"

然后，确保C＃语法代码如下：

<PackageReference Include="mongocsharpdriver" Version="2.7.3" /> <PackageReference Include="MongoDB.Bson" Version="2.7.3" /> <PackageReference Include="MongoDB.Driver" Version="2.7.3" /> <PackageReference Include="MongoDB.Driver.Core" Version="2.7.3" />

无法在mongo db中设置副本集
