Gin, Get form-data nested object sending with postman

Question

So basically I want to use PostFormMap() method to get my data sent from postman's form-data but I get unexpected result and the reason that I'm not using raw json is that I want to upload a file too Here is my postman

here is the code (nothing fancy)

c.JSON(200, gin.H{
    "request": c.PostFormMap("rules"),
})

and I'm expecting to get

{
    "request": [
        {
            "cell": "A",
            "rule": "B"
        },
        {
            "cell": "B",
            "rule": "D"
        }
    ]
}

but instead I get this

{
    "request": {
        "0": "B",
        "1": "D"
    }
}

The question is how can I get the correct result?

Answering my own question

After spending hours of searching and having PHP background in my mind I realized that having such form-data parameter like foo[0][bar] manually implemented in PHP and is not a standard thing so in my case I decided to send the second parameter as a raw json so it would be

Postman Body => form-data

Key	Value
file	sample.xlsx
rules	[{"cell": "A", "rules": "string"}, {"cell": "B", "rules": "numeric"}]
