"unsupported URL" 从 FBSDKGraphRequest 获取照片时

Question

我正在尝试通过图表 api 从 Facebook 获取照片。当我在 Graph api 中尝试此 url 时，这有效但在我的代码中无效。我遇到以下错误：

Domain=kCFErrorDomainCFNetwork Code=-1002 "unsupported URL" UserInfo={NSErrorFailingURLStringKey=(null)?

我的代码如下

let fbRequest = FBSDKGraphRequest(graphPath: "227325594139454?fields=photos.limit(10){images}", parameters: nil)
let graphConnection = FBSDKGraphRequestConnection()
                            graphConnection.addRequest(fbRequest, completionHandler: { (connection:FBSDKGraphRequestConnection!, result:AnyObject!, error:NSError!) -> Void in
                                if(error != nil){

                                }
                                else
                                {
})

这很容易 url 不支持“{}”，所以只需替换 html 代码中的“{”和“}”就可以了。所以“{”会变成%7B，而“}”会变成%7D.

let fbRequest = FBSDKGraphRequest(graphPath: "227325594139454?fields=photos.limit(10)%7Bimages%7D", parameters: nil)
