Overview
When passing InputTransformer as input to an Aws::Client method, you can use a vanilla Hash:
{
input_paths_map: {
"InputTransformerPathKey" => "TargetInputPath",
},
input_template: "TransformerInput", # required
}
Contains the parameters needed for you to provide custom input to a target based on one or more pieces of data extracted from the event.
Returned by:

-
#input_paths_map ⇒ Hash<String,String>
Map of JSON paths to be extracted from the event.
-
#input_template ⇒ String
Input template where you specify placeholders that will be filled with the values of the keys from
InputPathsMap
to customize the data sent to the target.
Instance Attribute Details
#input_paths_map ⇒ Hash<String,String>
Map of JSON paths to be extracted from the event. You can then insert
these in the template in InputTemplate
to produce the output you want
to be sent to the target.
InputPathsMap
is an array key-value pairs, where each value is a valid
JSON path. You can have as many as 10 key-value pairs. You must use JSON
dot notation, not bracket notation.
The keys cannot start with \"AWS.\"
#input_template ⇒ String
Input template where you specify placeholders that will be filled with
the values of the keys from InputPathsMap
to customize the data sent
to the target. Enclose each InputPathsMaps
value in brackets:
<value> The InputTemplate must be valid JSON.
If InputTemplate
is a JSON object (surrounded by curly braces), the
following restrictions apply:
The placeholder cannot be used as an object key.
Object values cannot include quote marks.
The following example shows the syntax for using InputPathsMap
and
InputTemplate
.
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status":
"$.detail.status"},
"InputTemplate": "<instance> is in state <status>"
}
To have the InputTemplate
include quote marks within a JSON string,
escape each quote marks with a slash, as in the following example:
"InputTransformer":
{
"InputPathsMap": {"instance": "$.detail.instance","status":
"$.detail.status"},
"InputTemplate": "<instance> is in state \"<status>\""
}
