Running the sample JSON Request on .NET server
A Corticon Server installation provides a JSON sample and a test script that runs the sample.
Note: JSON datatypes require double-quotes only on String values. As JSON does not have a date datatype, Corticon treats time values as Strings. When the other datatypes -- Booleans and numbers -- are in quotes, Corticon interprets the datatype from its Vocabulary properties and removes the quotes. Output will conform to the JSON syntax.
The sample, located at [CORTICON_WORK_DIR]\Samples\Rule Projects\OrderProcessing\OrderProcessingPayload.json, is as follows:

{"name": "ProcessOrder",
"Objects": [{
"total": null,
"shipped": null,
"item": [
{
"product": "Ball",
"price": "10.000000",
"quantity": "20",
"subtotal": null,
"__metadata": {
"#id": "Item_id_7",
"#type": "Item"
}
},
{
"product": "Racket",
"price": "20.000000",
"quantity": "1",
"subtotal": null,
"__metadata": {
"#id": "Item_id_8",
"#type": "Item"
}
},
{
"product": "Wrist Band",
"price": "5.250000",
"quantity": "2",
"subtotal": null,
"__metadata": {
"#id": "Item_id_9",
"#type": "Item"
}
}
],
"shippedOn": null,
"__metadata": {
"#id": "Order_id_1",
"#type": "Order"
},
"dueDate": "1/1/2008",
"note": null
},
{
"total": null,
"shipped": null,
"item": [
{
"product": "Pencil",
"price": "1.000000",
"quantity": "10",
"subtotal": null,
"__metadata": {
"#id": "Item_id_10",
"#type": "Item"
}
},
{
"product": "Notebook",
"price": "3.000000",
"quantity": "2",
"subtotal": null,
"__metadata": {
"#id": "Item_id_11",
"#type": "Item"
}
},
{
"product": "Eraser",
"price": "2.000000",
"quantity": "1",
"subtotal": null,
"__metadata": {
"#id": "Item_id_12",
"#type": "Item"
}
}
],
"shippedOn": null,
"__metadata": {
"#id": "Order_id_2",
"#type": "Order"
},
"dueDate": "1/1/2009",
"note": null
}
]}

Note: The sample sets the Decision Service name as a parameter in the JSON request. You could add other parameters such as the version and effective timestamp, as shown:
{
"name": "string",
"majorVersion": "string",
"minorVersion": "string",
"effectiveTimestamp": "string",
"Objects": [
To run the JSON sample:
1. Start Corticon Server the IIS server that is hosting the Corticon .NET application.
2. Open a command prompt window at [CORTICON_HOME]\Server .NET\samples\bin.
3. Launch Corticon-Api-Rest-Test.exe.
4. Enter 142.
5. When prompted for Input JSON File Path, enter the path to the sample:
C:\Users\{user}\Progress\CorticonWork_5.7\Samples\Rule Projects\OrderProcessing\OrderProcessingPayload.json
The request is processed, and its output is placed at [CORTICON_WORK_DIR]\output with a name formatted as OutputCRString_{epochTime}.json where {epochTime} is the number of seconds that have elapsed since 1/1/1970. The input file is also placed there. The output for the sample is as follows:
