post array of json with alamofire swift

Question

How can i post array of json objects with alamofire in swift?

my final data (which i want to post) looks like:

temp = [{
        "time": 1,
        "score": 20,
        "status": true,
        "answer": 456
    },
    {
        "time": 0,
        "score": 0,
        "status": false,
        "answer": 234
    },
    {
        "time": 0,
        "score": 20,
        "status": true,
        "answer": 123
    }
]

i got hint that i have to create custom parameter encoding but i am confused how can i do that. Someone please help me.

my current code looks like
let parameters: Parameters = [
    "answers": temp,
    "challenge_date": "2019-03-01"
]

Alamofire.request("...url", method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers)
    .responseJSON {
        response in

            if
        let status = response.response ? .statusCode {
            let classFinal: JSON = JSON(response.result.value!)

            if (status > 199 && status < 300) {
                self.dismiss(animated: true)
            } else {


            }
        }

    }

I guess temp is your array. Any errors that you are facing with this? — Ganesh Somani, Mar 01 '19 at 10:47
you need to send temp in the format of array & dict. See carefully, treat `[ ... ]` as array and `{ ... }` as dict. Now set **answers** value with this. **NOTE** Your post req params data is always be in array and dict not json. — dahiya_boy, Mar 01 '19 at 10:52

How is your `Parameters` class implemented. That is the source of your error. — Ganesh Somani, Mar 01 '19 at 10:56

In your code change method .put to .post, and not required to SVProgressHUD.dismiss() in else, because you already dismiss before if else part

Also, you need to convert your JSON string(temp variable) to array and then pass with the parameter.

let parameters: Parameters = [
            "answers": temp,
            "challenge_date": "2019-03-01"
        ]

    Alamofire.request("...url", method: .post, parameters: parameters, encoding:  JSONEncoding.default , headers: headers)
        .responseJSON { response in

            if let status = response.response?.statusCode {
            let classFinal : JSON = JSON(response.result.value!)
                SVProgressHUD.dismiss()
                if status > 199 && status < 300 {                    
                     self.dismiss(animated: true)
                }
            }
    }

yes. still getting error "JSON parse error - No JSON object could be decoded" – Deepak Verma Mar 01 '19 at 10:52
temp is your JSON string right?, So you need to convert JSON to the dictionary and then pass with the parameter – AtulParmar Mar 01 '19 at 10:54
first, check your request and parameter with the postman, is it working fine? – AtulParmar Mar 01 '19 at 11:22

I hope your Parameters class follows Codable protocol.

As far as I see, you are getting an error parsing that object to JSON. Hence that is the source of your error.

Could you also add code for your Parameters class / struct

First, convert your Temp

Array into String

than pass in that in parameters of Alamofire.

extension NSArray {
    
    func toJSonString(data : NSArray) -> String {
        
        var jsonString = "";
        
        do {
            
            let jsonData = try JSONSerialization.data(withJSONObject: data, options: .prettyPrinted)
            jsonString = NSString(data: jsonData, encoding: String.Encoding.utf8.rawValue)! as String
            
        } catch {
            print(error.localizedDescription)
        }
        
        return jsonString;
    }
    
}

temp is an array of json not a dictionary – Deepak Verma Mar 01 '19 at 11:16
Now pass your Array and get String. – Anup Gupta Mar 01 '19 at 11:27
