post array of json with alamofire swift - ios

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 {
}
}
}

Answer 1

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)
}
}
}

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

Answer 3

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;
}
}
