How do I access an embedded JSON value using Alamofire and SwiftyJSON?
I am trying to access nested JSON results using swiftyJSON and Alamofire. My print value is zero and I believe that I am not doing this correctly. What should be my parameters? I am trying to get the price value located at http://quotes.rest/qod.json
func getAPI() {
Alamofire.request(.GET, "http://quotes.rest/qod.json", parameters: ["contents": "quotes"])
.responseJSON { response in
if let JSON = response.result.value {
print(JSON["quote"])
}
}
}

You quotes
have an array in your JSON , so if you want to access the quote
first object, you must do so by accessing the first object:
func getAPI() {
Alamofire.request(.GET, "http://quotes.rest/qod.json", parameters: ["contents": "quotes"])
.responseJSON { response in
if let jsonValue = response.result.value {
let json = JSON(jsonValue)
if let quote = json["contents"]["quotes"][0]["quote"].string{
print(quote)
}
}
}
}

If the json syntax is incorrect as it is fully printed, you should notice what is wrong.
func getAPI() {
Alamofire.request(.GET, "http://quotes.rest/qod.json", parameters: ["contents": "quotes"])
// JSON response
.responseJSON { response in switch response.result {
case .Failure(let error):
// got an error in getting the data, need to handle it
print("error calling GET, json response type :")
// print alamofire error code
let statusCode = error.code
print("error code json : \(statusCode)")
// print json response from server
if let data = response.data {
print("Response data: \(NSString(data: data, encoding: NSUTF8StringEncoding)!)")
}
// print http status code plus error string
print(NSHTTPURLResponse.localizedStringForStatusCode(statusCode))
if let httpResponse : NSHTTPURLResponse = response.response {
print("HTTP Response statusCode: \(httpResponse.statusCode)")
}
case .Success( _):
let statusCode = (response.response?.statusCode)!
print("status code json : \(statusCode)")
print("there is a response json")
//print(value)
// parse the result as JSON, since that what the API provides and save datas as new user in coreData
guard let data = response.data else {
print("Error parsing response data")
return
}
let json = JSON(data: data)
// access first element of the array
if let postContent = json["contents"]["quotes"][0]["quote"].string{
// deal with json
}
}
}
