使用 Swift 解析 JSON 的问题

Question

我有一个包含此人对象的 JSON 文件。每个人都有不同的信息。这是 JSON 文件的结构。

[
  {
    "person": {
      "name": "Dani",
      "job": "Artist",
      "country": "FR",
      "sold": "992",
      "email": "Dani",
      "facebook": "Artist",
      "twitter": "Dani",
      "instagram": "Artist",
      "snapchat": "Dani",
      "photo": "Artist"
    }
  },
  {
    "person": {
      "name": "Alex",
      "job": "",
      "country": "TU",
      "sold": "992",
      "email": "Dani",
      "facebook": "Artist",
      "twitter": "Dani",
      "instagram": "Artist",
      "snapchat": "Dani",
      "photo": "Artist"
    }
  }
]

我能够打开 json 文件，但无法解析它。这是我的代码

 func lodData()
    {
        let data = NSData(contentsOfURL: url!)



        do {
            let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments)

            if let person = json["person"] as? [[String: AnyObject]] {
                for p in person {
                    if let name = p["name"] as? String {
                        names.append(name)
                    }
                }
            }
        } catch {
            print("error serializing JSON: \(error)")
        }

        print(names) 

    }

因此，名称数组仍然为空。

person is [String: String] 表示字典不是数组......你可以这样做

 if let data = json as? [[String: AnyObject]] {
      for p in data {
          if let person = p["person"] as? [String: String]{
              names.append(person["name"])
          }
       }
  }
