得到200个响应，但不显示json值

Question

我已经使用“ wordsapi”写了一个网络请求，并且状态为200，但是收到的响应不在json中。

我的代码可以构建并运行，我只需要json中的响应即可。

    let wordsAPI = 
    "https://wordsapiv1.p.mashape.com/words/money/synonyms"
    let wordsAPIEndPoint = NSURL(string: wordsAPI)
    let request = NSMutableURLRequest(url: wordsAPIEndPoint! as 
     URL)

    request.setValue("mapkey", forHTTPHeaderField: "X-Mashape-Key")
    request.httpMethod = "GET"
    let session = URLSession.shared

    let synonymResponse = session.dataTask(with: request as 
     URLRequest) { (data, response, error) -> Void in
        if let resp = response as? HTTPURLResponse {
           print(resp)
        }
     }
     synonymResponse.resume()

//我收到的回复

    { Status Code: 200, Headers {
    "Accept-Ranges" =     (
    bytes
    );
    "CF-RAY" =     (
     "4d4d9aacabdccf5c-IAD"
    );
    Connection =     (
    "keep-alive"
    );
    "Content-Length" =     (
    30
    );
    "Content-Type" =     (
    "application/json; charset=utf-8"
     );Date =     (
    "Fri, 10 May 2019 17:24:00 GMT"
      );

我需要在json中获取我设置为端点的任何值的同义词的响应。在这种情况下是“钱”

您需要完整使用data var，其中包含收到的json数据

let wordsAPI = "https://wordsapiv1.p.mashape.com/words/money/synonyms"
let wordsAPIEndPoint = URL(string: wordsAPI)
var request = URLRequest(url: wordsAPIEndPoint!) 
request.setValue("mapkey", forHTTPHeaderField: "X-Mashape-Key")
request.httpMethod = "GET"

URLSession.shared.dataTask(with: request) { (data, response, error) -> Void in
    guard let data = data else { return }
    let res = try! JSONDecoder().decode(Root.self,from:data)
    print(res.synonyms)
}.resume()

struct Root:Codable {
  let word:String
  let synonyms:[String]
