Question

我从功能应用程序通过服务总线主题触发器收到以下响应，在这里我想过滤出记录类型为DOC TYPE AS为“ REC”且ComputerModel为“ Yuli”的记录ID。因此，对于从服务总线触发器获得的以下响应，我应该获得值ID：“ MARAS_1S4810L8010016000075_20201015T130058Z”，我将在代码中进一步查询。我想为我完成这段代码提供一些帮助。

在控制台中响应mySbMsg：

[{“ Id”：“ MARAS_1S4810L8010016000075_20201015T130058Z”，“ DocType”：“ REC”，“ Tags”：[]，“ Properties”：{“ Access”：“ COMMON”，“ BIOSSerialNumber”：“ 0075”，“ CalibHash“：” aoI8zg“，” ComputerBuild“：” EE-FVT“，” ComputerModel“：” Yuii“，” Customer“：” MAARS“，” Location“：” Mumb“，” LogPresenceDuration“：” 120“，”型号”：“ YTOPI 44880132-aoI8zg”，“ CompanyXYZ”：“ false”，“ RadarFPS”：“ 4”，“ RadarModule”：“ YTOPI”，“ RadarMount”：“ Yuii”，“ RadarRevision”：“ Rev4”， “ RecorderRelease”：“ Recorder_Platform_Minimal-Release049_20200924T143831”，“ RecordingType”：“ UX”，“ ResistorValueOhm”：“ 75”，“ ScreenTiltAngle”：“ 120”，“ UniqueSystemID”：“ 1S4810L8010016000075”，“ UserChairX”：“ 0， “ UserChairZ”：“ 0”，“ UserSittingMode”：“倾斜右侧”，“ UserWalkInRepetitions”：“ 1”，“ uDriverVersion”：“ v2_0_6”}，“类别”：[]，“触发器”：true，“已收到“：” 2020-10-15T14：58：25.3357416Z“}， {“ Id”：“ MAARS_Yuii_UX | MAARS_2.1.1.1_1S4810L8010016000075_20201015T130732Z”，“ DocType”：“ ASS”，“标签”：[]，“属性”：{“访问”：“ COMMON”，“ BIOSSerialNumber”：“ 16000075” ，“ CalibHash”：“ aoI8zg”，“ ComputerBuild”：“ EE-FVT”，“ ComputerModel”：“ Yuii”，“客户”：“ MAARS”，“位置”：“ Mumb”，“ LogPresenceDuration”：“ 120” ，“ Model”：“ YTOPI 44880132-aoI8zg”，“ CompanyXYZ”：“ false”，“ RadarFPS”：“ 4”，“ RadarModule”：“ YTOPI”，“ RadarMount”：“ Yuii”，“ RadarRevision”：“ Rev4 “，” RecorderRelease“：” Recorder_Platform_Minimal-Release049_20200924T143831“，” RecordingType“：” UX“，” ResistorValueOhm“：” 75“，” ScreenTiltAngle“：” 120“，” UniqueSystemID“：” 1S4810L8010016000075“，” UserChairX“：” 0 “，” UserChairZ“：” 0“，” UserSittingMode“：”向后倾斜“，” UserWalkInRepetitions“：” 1“，” uDriverVersion“：” v2_0_6“}，”类别“：[]，”触发器“：true，”收到“：”“ 2020-10-15T14：58：25.3357755Z”}]

代码：

    namespace ServiceBusCopyFunction
{
    public static class GetMetadataFromSB
    {
        
        [FunctionName("GetMetadataFromSB")]
        public static void Run([ServiceBusTrigger("TopicName", "Topic Subscription", Connection = "AzureServiceBusString")] string mySbMsg, ILogger log)
        {
            log.LogInformation($"C# ServiceBus topic trigger function processed message: {mySbMsg}");

        }
    }
}

我弄清楚了，学习了如何创建Model和反序列化JSON数据。这是对“ DocType”属性进行过滤的代码：

 var jsonSerializerSettings = new JsonSerializerSettings();
            jsonSerializerSettings.MissingMemberHandling = MissingMemberHandling.Ignore;
            List<MyItem> lists = JsonConvert.DeserializeObject<List<MyItem>>(mySbMsg, jsonSerializerSettings);
            List<string> filteredResult = (from s in lists
                                          where s.DocType == "REC"
                                 select s.Id).ToList();

        }
        catch(Exception e )
        {
            log.LogError( $"Error while catching messages; {e.Message}\n" );
            
        }

    }

    public class MyItem
    {
        public string Id;
        public string DocType;
        public string Project;
        public string ProjectId;
        public MyProperties Properties;
       
        
    }
    public class MyProperties
    {
       public string Access;
       public string BIOSSerialNumber;
    }

}
}
