Swift|Swift 百度API调用及json解析
1. 百度API调用
2.1 系统 NSJSONSerialization
2.2 第三方 SwiftyJSON
import UIKitclass ViewController: UIViewController {var json: AnyObject?
var dicData: NSDictionary!
var jsonSwity: JSON!override func viewDidLoad() {
super.viewDidLoad()let cityName = "beijing"
let apiKey = "--------your api key---------"
let callBack = APISCallBack()
let url = "http://apis.baidu.com/heweather/weather/free"
let method = "post"
let parameter = NSMutableDictionary()
parameter.setObject(cityName, forKey: "city")
ApiStoreSDK.executeWithURL(url, method: method, apikey: apiKey, parameter: parameter, callBack: callBack)callBack.onSuccess = { (status, responseString) -> Void in
NSLog("Success")
let data = responseString.dataUsingEncoding(NSUTF8StringEncoding)// 系统 NSJSONSerialization
self.json = try! NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers)// 第三方 SwiftyJSON
self.jsonSwity = JSON(data: data!)self.resolvingjson()
self.initLabelView()
}callBack.onError = { (status, responseString) -> Void in
NSLog("Error")
}callBack.onComplete = { () -> Void in
NSLog("Complete")
}
}// 解析json数据
func resolvingjson() {if let dict = json as? NSDictionary {
if let arr = dict["HeWeather data service 3.0"] as? NSArray {
if let dict2 = arr[0] as? NSDictionary {
if let dict3 = dict2["basic"] as? NSDictionary {self.dicData = https://www.it610.com/article/dict3
}
}
}
}}// initLabelView
func initLabelView() {
let label1 = UILabel(frame: CGRect(x: self.view.bounds.width/2 - 40, y: 50, width: 80, height: 40))
let label2 = UILabel(frame: CGRect(x: self.view.bounds.width/2 - 40, y: 100, width: 80, height: 40))
let label3 = UILabel(frame: CGRect(x: self.view.bounds.width/2 - 40, y: 150, width: 80, height: 40))
self.view.addSubview(label1)
self.view.addSubview(label2)
self.view.addSubview(label3)label1.text = dicData["city"] as? String
label2.text = dicData["cnty"] as? String// SwiftyJSON解析
label3.text = jsonSwity["HeWeather data service 3.0"][0]["status"].string
}
