Append multiple data to httpbody of URLRequest - ios

Question

I want to append another dictionary as a parameter to httpBody of URLRequest
Request Model:
struct RequestModel: Encodable {
let body: Body
}
struct Body: Encodable {
let name: String
let score: String
let favList: [String]
}
Api Request:
do {
var urlRequest = URLRequest(url: resourceURL)
urlRequest.httpMethod = kHTTPMethodPOST
urlRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
urlRequest.httpBody = try JSONEncoder().encode(self.requestModel)
let dataTask = URLSession.shared.dataTask(with: urlRequest) { data, response, error in
guard let httpResponse = response as? HTTPURLResponse,
httpResponse.statusCode == 200,
let jsonData = data else {
completion(.failure(.responseError))
return
}
}
dataTask.resume()
} catch {
completion(.failure(.unknownError))
}
Another dictionary: airports
var airports: [String: String] = ["YYZ": "Toronto Pearson", "DUB": "Dublin"]
trying to append airports dictionary parameter to URLRequest but can't append.
Appreciate your help and suggestion!
Thanks

Answer 1

If you have to append the airports dictionary to the request body, you may want to include it in the Request model itself.
I would suggest updating your RequestModel and make it Encodable.
And include your airports dict as a part of your RequestModel
Something like this
struct RequestModel: Encodable {
let body: Body
let airportsDict: [String:String]
}
struct Body: Encodable {
let name: String
let score: String
let favList: [String]
}
This way your httpBody will have all the data you want to pass.
Hope this helps

The usual syntax to POST JSON is
do {
var urlRequest = URLRequest(url: resourceURL)
urlRequest.httpMethod = "POST"
let postData = try JSONEncoder().encode(self.requestModel)
urlRequest.httpBody = postData
urlRequest.setValue("\(postData.count)", forHTTPHeaderField:"Content-Length")
urlRequest.setValue("application/json", forHTTPHeaderField:"Accept")
urlRequest.setValue("application/json", forHTTPHeaderField:"Content-Type")
}
