How to send multiple JSON objects as a stream using alamofire

Question

I want to send multiple different JSON object in a single request, i felt streaming the multiple JSON objects like a file in a single request would be better, so kindly let

JSON format is not correct for your request, JSON is always key-value pair, where key is always String, and value is any Object. In your example need to set key at top level for object of type Array as below:

let SendParams = [
                    "key" :[["a":1234, "b":2345, "c":3456], ["a":2345, "b":3456, "c":4567], ["a":3456, "b":4567, "c":5678]]
                ]
_ = Alamofire.request(url, method: .post, parameters: SendParams, encoding: JSONEncoding.default, headers: headers).responseJSON { (response) in}

OR

Serialise the array and set as httpBody of URLRequest object:

    let url = YOUR_POST_API_URL
    var request = URLRequest(url: URL(string: url)!)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")

    let values = [
        ["a":1234, "b":2345, "c":3456], ["a":2345, "b":3456, "c":4567], ["a":3456, "b":4567, "c":5678]
    ]
    request.httpBody = try! JSONSerialization.data(withJSONObject: values)

    Alamofire.request(request)
        .responseJSON { response in
            // do whatever you want here
            switch response.result {
            case .failure(let error):
                print(error)

                if let data = response.data, let responseString = String(data: data, encoding: .utf8) {
                    print(responseString)
                }
            case .success(let responseObject):
                print(responseObject)
            }
    }
