Admin: Pre- and post-processing plugins

The Plugins section is used to record details of the pre- and post-processing plugins configured at the current RPI installation.

Pre-processing plugins can be used to manipulate visitor profiles prior to a call being made for a Realtime decision content.

A pre-processing plugin is defined as per the following example:

CODE

{
    "Name": "PreProcessing",
    "Factory": {
        "Assembly": "Redpoint.Resonance.Web.Shared",
        "Type": "Redpoint.Resonance.Web.Shared.Plugins.PreDecisionExampleFactory"  
},
    "Type": {
        "Name": "Predecision",
        "ApiContentFilterOperator": "Include",
        "ApiContextFilters": [
            "PrePluginTest"
        ]
    },
    "Settings": [
        {
            "Key": "Param",
            "Value": "Foo"
        }
    ]
}

The value passed in an API call's apiContext property is used to determine whether a pre-processing plugin is to be applied. You can specify multiple comma-delimited values in a list. apiContentFilterOperator is used to Include or Exclude whether a pre-processing plugin is to be invoked.

For example, if a value passed in apiContext when an API call is made matches a value in the web config setting ‘apiContextFilter’, and apiContentFilterOperator is set to Include, pre-processing plugin functionality will be called. The functionality would not be called if apiContentFilterOperator was set to Exclude.

Post-processing plugins are defined as per the following example:

CODE

{
    "Name": "PostProcessingExample",
    "Factory": {
        "Assembly": "Redpoint.Resonance.Web.Shared",
        "Type": "Redpoint.Resonance.Web.Shared.Plugins.PostDecisionExampleFactory"
},
    "Settings": [
        {
            "Key": "Prefix",
            "Value": "pre "
        },
        {
            "Key": "Suffix",
            "Value": "post"
        }
    ]
}

For more information, please see the RealtimeContentPlugins configuration setting in the RPI Reference guide.

RPI will look for plugin files in a location defined by the following application setting:

RealtimeAPIConfiguration__AppSettings__PluginAssemblyPath

The setting defaults to "/app/plugins".
