Usage sharing is enabled by default if using a pipeline builder that is derived from FiftyOnePipelineBuilder. For instance, the DeviceDetectionPipelineBuilder. In this example, we show how to add a ShareUsageElement to a Pipeline using configuration.
As with all ElementBuilders, this can also be handled in code, using the ShareUsageBuilder. The commented section in the example demonstrates this.
The appsettings.json file contains all the configuration options. These are all optional, so each can be omitted if the default for that option is sufficient:
{
"PipelineOptions": {
"Elements": [
{
"BuilderName": "ShareUsageBuilder",
"BuildParameters": {
"SharePercentage": 0.1,
"ShareUsageUrl": "https://devices-v4.51degrees.com/new.ashx",
"MinimumEntriesPerMessage": 50,
"RepeatEvidenceIntervalMinutes": 10,
"TrackSession": false,
"AspSessionCookieName": "asp.net_sessionid",
"IncludedQueryStringParameters": "a,b",
"ShareAllQueryStringParameters": false,
"BlockedHttpHeader": "MySecretHeader",
"IgnoreFlowDataEvidenceFilter": "evidenceKey:evidenceValue",
"ShareAllEvidence": false,
"AddTimeout": 5,
"TakeTimeout": 100
}
}
]
}
}
For further details of what each setting does, see the share usage builder reference
This example is available in full on GitHub.
Expected output
Constructing pipeline from configuration file.
Pipeline created with share usage element, evidence processed
with this pipeline will now be shared with 51Degrees using the
specified configuration.
