I make a GET call and receive a json response. I need to use that json response as one parameter for a subsequent POST call.
I’ve tried to:
-parse the data into an object and pass the [object] as parameter
-parse the data into a string and pass the string as parameter
-parse the data as dict and pass the dict as parameter
but it’s not working, I believe it’s a data thing or a secret I’m missing
How do you use a json response as parameter for a subsequent api call?
//MARK: - PIXLAB facedetect
func facedetectGET(uploadedUrl: String) {
var urlComponents = URLComponents(string: "https://api.pixlab.io/facedetect")
urlComponents?.queryItems = [
URLQueryItem(name: "img", value: uploadedUrl),
URLQueryItem(name: "key", value: Constants.pixlabAPIkey),
]
let url = urlComponents?.url
if let url = url {
// Create URL Request
var request = URLRequest(url: url, cachePolicy: .reloadIgnoringLocalCacheData, timeoutInterval: 10.0)
request.httpMethod = "GET"
request.addValue("Bearer \(Constants.pixlabAPIkey)", forHTTPHeaderField: "Authorization")
// Get URLSession
let session = URLSession.shared
// Create Data Task
let dataTask = session.dataTask(with: request) { (data, response, error) in
// Check that there isn't an error
if error == nil {
do {
let json = try JSONSerialization.jsonObject(with: data!, options: [])
//make a dict
//let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? [String: Any]
print("SUCCESS: image detected")
print(json)
//make json a string utf8 so it can be used as parameter in next call
//let jsonString = String(data: json as! Data, encoding: .utf8)
//let jsonData = json.data(using: .utf8)!
//parse json
//decode the json to an array of faces
let faces: [Face] = try! JSONDecoder().decode([Face].self, from: data!)
let facesString = String(faces)
//use dispatch main sync queue??"bottom": Int,
//mogrify call
mogrify(uploadedUrl: uploadedUrl, cord: faces)
}
catch {
print(error)
}
}
}
// Start the Data Task
dataTask.resume()
}
}
//MOGRIFY CALL
func mogrify(uploadedUrl: String, cord: Any) {
let mogrifyurl = URL(string: "https://api.pixlab.io/mogrify")!
//let param: [Face] = result.faces
let param: [String: Any] = ["img": uploadedUrl, "cord": cord]
var request = URLRequest(url: mogrifyurl)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("Bearer \(Constants.pixlabAPIkey)", forHTTPHeaderField: "Authorization")
request.httpMethod = "POST"
request.httpBody = try! JSONSerialization.data(withJSONObject: param, options: [])
URLSession.shared.dataTask(with: request) { (data, response, error) in
if error != nil {
print(error!)
return
}
do {
let json = try JSONSerialization.jsonObject(with: data!)
print(json)
} catch {
print("error")
}
}.resume()
}
this is how pretty the response looks like after serialization
when I decode it and pass it looks like this
