Skip to main content
Create a readable handle for JSON data from a URI or static text. This operation is useful when there is a need to read static JSON data, JSON data from a public URI, or JSON data from the output from another operation.

​
Required Parameters

  • None

​
Optional Parameters

  • uri: A JSON file URI (for example http://mydomain.com/resources/somedata.json or /tmp/myfile.json).
  • text: JSON text. This can be static JSON that is set on an ArcScript attribute, or the output from a previous operation in the script (such as the [http:content] output attribute of one of the http operations.) See the example below.

​
Output Attributes

  • handle: A readable handle reference to the JSON data. This handle can be used by subsequent operations (see the example below).
  • warning#: The warning array of the readable JSON handle.

​
Example

Here is an example that uses jsonOpen to create a handle for some static JSON text and then pass that handle to another operation (in this case, the second operation is jsonDOMGet):
When you use jsonOpen, make sure to use the corresponding jsonClose operation to close the handle at the end of the script to avoid leaking memory through open handles.
