How arrays in input data are interpreted
When the names of Form inputs in an incoming POST request contain two pairs of square
brackets: [..][..], the data are interpreted as an array. The value between the first pair of square
brackets is expected to consist of two parts, separated by an underscore (e.g. row_0). The first
part is considered to be the element's name. All content after the first underscore (preferably an
integer) will be used as index, which is given as an attribute of the element (e.g. <row _idx=0>).
This makes it easy to select all elements on the same level in a data mapping configuration,
and to convert the XML to a JSON object.
For an example see "Incoming HTML" on page802 and "Resulting XML structure with
Enhanced PHP-like arrays" on page802.
Output
First, the output inside the process itself is, depending on the selected options, an XML request
file, POST Attachments files, either one or both.
If the Send Immediate Response to client option is selected, the response file is sent back
right away and the involvement of the input task ends then.
However, if this option is not checked, it means there is a second output that comes out of the
NodeJS Server Input task: the last output generated by PReS Workflow is sent back to the
initial input, by which it is returned to the client.
Even if the process ends with a Delete task, it is still returned to the client; deleting the job file
only means you are not doing anything with it locally.
If the requested HTTP action is not available, a '404 not found' HTML page will be returned.
Note
You can serve static resources through PReS Workflow, which is especially useful for
images, CSS and JavaScript files. See "NodeJS Server Input plugin preferences 2" on
page808.
