如何使用Alamofire swift 3从此JSON获取值

Question

我正在尝试从此JSON获取值。 这是JSON的一部分，因为实际的JSON数据太长。

"hits" : [ {
"recipe" : {
  "uri" : "http://www.edamam.com/ontologies/edamam.owl#recipe_bd8def1d09d8c308f659e6945f366271",
  "label" : "Pinchos de carne",
  "image" : "http://img.recetascomidas.com/recetas/640_480/pinchos-de-carne.jpg",
  "source" : "Recetal Comidas",
  "url" : "http://pinchos-de-carne.recetascomidas.com/",
  "shareAs" : "http://www.edamam.com/recipe/pinchos-de-carne-bd8def1d09d8c308f659e6945f366271/carne",
  "yield" : 6.0,
  "dietLabels" : [ "Low-Carb" ],
  "healthLabels" : [ "Dairy-Free", "Gluten-Free", "Egg-Free", "Peanut-Free", "Tree-Nut-Free", "Soy-Free", "Fish-Free", "Shellfish-Free" ],
  "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",
    "weight" : 600.0
  }, {
    "text" : "2 cucharadas de pimentón dulce",
    "quantity" : 2.0,
    "measure" : "tbsp",

  }, {
    "text" : "1 cucharada de pimentón picante",
    "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，我想获取“配方”中的标签值。 我已在控制台中成功打印了所有JSON，但不知道如何获取配方值。

我希望你能帮助我。

这是我现在拥有的代码。

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")
    }
}

您的顶级json结构是一个字典。 因此，您需要将其解析为[String：Any]。 然后您的提示级别是一个JSON数组，因此您需要将其解析为[Any]

这是一个例子。 别忘了处理拆封

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

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

}
