PostData Shell Properties

Shell.PostData()

string (output). The POST data from the HTTP call.

You can use an HTTP POST to send JSON data to your script in the URL Direct Access Context. The POST body of the HTTP message is added as a string-Variant to the shell object with Shell.PostData() to provide the body.

First, note the following requirements:

• To protect from data overflow, this is limited to HTTP requests with a body of size X, where X is controlled by an entry in the TS_SYSTEMSETTINGS table named "ScriptPostDataMax" (otherwise, the default value is 10485760 bytes). If this value is not present in TS_SYSTEMSETTINGS, you can add it manually by following the steps described here.
• The request must be a POST (not a PUT, etc.)
• The HTTP header for the request must have a "Content-Type" of "application/json".

SBM ModScript has from_json(), which will convert the string from JSON to int and string values, with JSON object becoming a Map and JSON array becoming a Vector. As there is no implicit conversion from Variant to string, and since the values on the Shell are Variant, the Variant must be explicitly converted to string while being passed to from_json().

For example:

var y = from_json( Shell.PostData().to_string() );

An example of using the parsed values after calling from_json() is available in Sample Five: RESTDataSource.
