Hi, so which way in the answer did you choose to solve your issue. I have the same issue, but if we use the first way, I don't know which field should we put the json of all params — t4nhpt

Now you have two ways to do it:

1: Make whole params as a JSON

2: Make only the array as an encoded JSON string.

In your case you can use 1:

let list = ["ffff","bbbb","cccc"] 

let data = try! JSONSerialization.data(withJSONObject: list, options: .prettyPrinted)

let jsonString = String(data: data, encoding: .utf8)!

let params = [
    "a" : "a",
    "b" : "b",
    "list : jsonString
]

thank you for help me! : ) but If I send ["aaa", "BBB"], the server will send '[\ n "aaa", \ n "BBB" \ n]' I get the value this way. Why?

So basically server need to handle it by the stripes method in laravel php.

umm... is it impossible then to send ["aaa", "BBB"]?

You can't pass array directly.
