Assign incremental keys to the objects in an array In MuleSoft
Sure, here is how youcan assign incremental keys to the objects in an array in MuleSoft 4:
XML
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ee="http://www.mulesoft.org/extensions/ee"
xmlns:db="http://www.mulesoft.org/extensions/db"
xsi:schemaLocation="http://www.mulesoft.org/schema/mule/ee/4.4.0 http://www.mulesoft.org/schema/mule/ee/4.4.0/mule.xsd">
<flow name="assign_keys_flow">
<set-payload value="#[payload.map { it << ['key': 1] }.toList()]" />
<logger message="Modified data: #[payload]" level="INFO" />
</flow>
</mule>
This Mule flow uses a set-payload component to achieve this. The set-payload component takes the input JSON array and applies a map expression to it. The map expression iterates over each object in the array and adds a new key-value pair "key": 1 to it. The toList() method converts the resulting list of objects back into an array.
The modified data is then logged to the console using a logger component.
You can modify this flow to suit your specific needs, such as using a different starting value for the key or adding additional logic to the map expression.
Here is an example of how the flow would work with the sample data you provided:
JSON
[
{
"name": "Alice",
"age": 30,
"key": 1
},
{
"name": "Bob",
"age": 25,
"key": 1
},
{
"name": "Charlie",
"age": 35,
"key": 1
}
]
As you can see, each object in the array now has a new key-value pair "key": 1.
