azure logic app compose action

Question

In Azure logic apps I am creating a Json body in compose action. JSON structure is like below I am passing place property value as an variable i.e. variables('result'):

{
   "place": [
                {  "visit":"name"
                     },
               {    "visit":"name"
                     }
            ]
}

In compose action how to get the above structure as i could not get the exact array like structure. I've tried a lot of things, but the result is like below:

{
       "place": "[
                    {  "visit":"name"
                         },
                   {    "visit":"name"
                         }
                ]"
 }

Double quotes are getting appended in the variable in compose action. If I pass as an array in compose means got like below double quotes is there in every element of array. I don't want doubles quotes inside array elements and I want the value as a variable in compose action's property:

{
           "place": [
                        "{  "visit":"name"
                             }",
                       "{    "visit":"name"
                             }"
                    ]
        }
 }

Please let me know hot to get the exact structure.

Answer 1

I'm assuming your result variable is of type array and contains the following value (you can check this in your run history):

[
    "{\"visit\":\"London\"}",
    "{\"visit\":\"Paris\"}"
]

Note that I created my result variable using an expression - createArray('{"visit":"London"}','{"visit":"Paris"}')

You can add a For each that takes the result variable as its input.

Within the For each you can include a Parse JSON action that takes Current item as the Content. You will need to provide the schema of your array objects also.

{ "type": "object", "properties": { "visit": { "type": "string" } } }

Outside of the For each loop you can then create a Compose action. The code view for the Compose action looks like this.

{
    "inputs": {
        "place": "@actionBody('Parse_JSON')"
    }
}

The output from this is the following:

{
    "place": [
        {
            "visit": "London"
        },
        {
            "visit": "Paris"
        }
    ]
}
