Question

我正在尝试从此JSON获取值。这是JSON的一部分，因为真正的JSON数据太长了。

"hits" : [ {
"recipe" : {
  "uri" : "http://www.edamam.com/ontologies/edamam.owl#recipe_bd8def1d09d8c308f659e6945f366271",

  "cautions" : [ ],
  "ingredientLines" : [ "600 gr. de carne magra de cerdo", "2 cucharadas de pimentón dulce", "1 cucharada de pimentón picante", "1 cucharada de cúrcuma", "1 cucharada de sazonador especial para carnes", "3 cucharadas de perejil fresco bien picadito", "1/2 cucharada de comino", "Aceite de oliva", "3 patatas", "1 diente de ajo", "Pimienta negra", "Sal" ],
  "ingredients" : [ {
    "text" : "600 gr. de carne magra de cerdo",
    "quantity" : 600.0,
    "measure" : null,
    "food" : "carne magra cerdo",

    "quantity" : 1.0,
    "measure" : "tbsp",
    "food" : "pimenton picante",
    "weight" : 6.8
  }, {
    "text" : "1 cucharada de cúrcuma",
    "quantity" : 1.0,
    "measure" : "tbsp",
    "food" : "curcuma",
    "weight" : 6.8
  }, {
    "text" : "1 cucharada de sazonador especial para carnes",
    "quantity" : 1.0,
    "measure" : "tbsp",
    "food" : "sazonador",
    "weight" : 2.7
  }, {
    "text" : "3 cucharadas de perejil fresco bien picadito",
    "quantity" : 3.0,
    "measure" : "tbsp",
    "food" : "perejil fresco",
    "weight" : 11.4
  }, {
    "text" : "1/2 cucharada de comino",
    "quantity" : 0.5,
    "measure" : "tbsp",
    "food" : "comino",
    "weight" : 3.0
  }, {
    "text" : "Aceite de oliva",
    "quantity" : 2.0,
    "measure" : "tbsp",
    "food" : "aceite oliva",
    "weight" : 27.0
  }, {
    "text" : "3 patatas",
    "quantity" : 3.0,
    "measure" : null,
    "food" : "patatas",
    "weight" : 195.0
  }, {
    "text" : "1 diente de ajo",
    "quantity" : 1.0,
    "measure" : null,
    "food" : "ajo",
    "weight" : 3.0
  }, {
    "text" : "Pimienta negra",
    "quantity" : 1.0,
    "measure" : "peppercorn",
    "food" : "pimienta negra",
    "weight" : 0.3
  }, {
    "text" : "Sal",
    "quantity" : 0.0,
    "measure" : null,
    "food" : "sal",
    "weight" : 3.3346887
  } ]

例如，我想获得“食谱”内的标签值。我成功地在控制台中打印了所有JSON，但我不知道如何获取配方值。

我希望你能帮助我。

这是我现在的代码。

let url: String = "https://test-es.edamam.com/search?q=pollo"
var arregloHits: NSMutableArray = []

override func viewDidLoad() {
    super.viewDidLoad()

    pruebaJson()
}

func pruebaJson(){
    if ControladorService.conexionInternet(){
        ControladorService.sharedInstance.callUrlWithCompletion(url: url, params: nil, completion: { (finished, response) in
            if finished{
                let result = NSMutableArray(array: response["hits"] as! NSArray)

                self.arregloHits = result
                print(self.arregloHits)
            }else{
                print("Connection failed")
            }
        }, method: .get)
    }else{
        print("No Internet")
    }
}

你的顶级json结构是一本字典。所以你需要将它解析为[String：Any]。那么你的提示级别是一个JSON数组，所以你需要将它解析为[Any]

这是一个例子。不要忘记处理解包

do{
    let json = try JSONSerialization.jsonObject(with: yourJSONData, options: []) as? [String: Any]

    let hits = json?["hits"] as? [Any]
    dump(hits)
}catch let error{

}

如何使用Alamofire swift 3从这个JSON获取值
