iOS Swift - Google Place API(Web)以奇怪的格式返回 JSON

Question

我正在使用 Swift 3 构建一个 iOS 应用程序，我正在使用 Google Places API 获取地点数据。我正在使用 iOS API 来获取我需要的大部分数据。但我还需要获取 iOS API(尚未)提供的开放时间。

所以我必须查询 Web API 才能获取该信息。请求端工作正常，但是，一旦我得到结果并使用 JSONSerialisation 将其转换为 JSON，然后在控制台中打印输出，这个 JSON 的格式很奇怪，我'我正在努力解析它。

当我将它粘贴到 JSON 阅读器时，它说它无效。

这是我觉得带有这些“(”和“=”的 JSON:

Answer 1

问题是 reponseData 是一个字典，其键 response 包含您想要的实际字典。 JSON 类似于:

{
    "result": {
        "website": "example.com"
    }
}

所以正确的代码应该是:

let url = URL(string: "https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJheCrEY6AhYARxCkT8_KjDWE&key=[MYAPIKEY]")

let urlRequest = URLRequest(url: url!)


let task = URLSession.shared.dataTask(with: urlRequest) {
    (data, response, error) in

    guard error == nil else {
        print(error!)
        return
    }

    guard let responseData = data else {
        print("Error: did not receive data")
        return
    }

    do {
        guard let placeData = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.allowFragments)
            as? [String: Any] else {
                print("error trying to convert data to JSON")
                return
        }

        print("The placeData is: \(placeData.description)")

        guard let website = (placeData["result"] as? [String : Any])?["website"] as? String else {
            print("Could not get the website from JSON")
            return
        }
        print("The title is: \(website)")
    } catch  {
        print("error trying to convert data to JSON")
        return
    }
}
task.resume()

我只是改变了:

guard let website = placeData["website"] as?字符串其他 {

到:

guard let website = (placeData["result"] as? [String : Any])?["website"] as?字符串其他 {
