我正在Swift 3中构建一个iOS应用，并且正在使用Google Places API来获取位置数据。我正在使用iOS API来获取所需的大部分数据。但是我还需要获取iOS API尚未提供的开放时间。
因此，我必须查询Web API才能获取该信息。请求方面的工作正常，但是，一旦获得结果并将其转换为JSON，JSONSerialisation然后在控制台中打印输出，此JSON的格式就很奇怪了，我正在努力对其进行解析。
当我将其粘贴到JSON阅读器中时，它说这是无效的。
这是使用这些“（”和“ =”对我来说看起来很奇怪的JSON：

You'll usually find it occupied by folks busy working away on their laptops.\n\n***Accessibility Info***\n\nVenue - On the smaller side, as far as cafes/coffee shops go, with about 2/3 of the seating being accessible: those along the walls were bench seating, and there's lower coffee table seating towards the right as well, leaving only the middle aisle and outer seats along the sides accessible.\n\nBathroom - Didn't try them.";

任何了解正在发生的事情的帮助将不胜感激。最终目标是获取字典的开放时间，其关键字为星期几，数值为开放时间。
提前致谢
问题是这reponseData是一个字典，其中的键response包含所需的实际字典。JSON如下所示：
{
"result": {
"website": "example.com"
}
}
因此正确的代码将是：
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? String else {
至：
guard let website = (placeData["result"] as? [String : Any])?["website"] as? String else {
