通过 Facebook Graph API 快速获取个人资料图片返回“不支持的 URL"； [英] Getting profile picture with swift through Facebook Graph API return "unsupported URL"

问题描述

我正在为 iOS 开发一个应用程序，用户应该使用 facebook 登录.所以我试图获取用户的个人资料图片，但以下代码返回 "unsupported URL"

I'm developing an app for iOS that user should login with facebook. So i'm trying to get the users profile picture but the following code is returning "unsupported URL"

FBRequestConnection.startWithGraphPath("(userID)/picture?type=large&access_token=207613839327374|BgKi3AePtvg1oDO8GTbWqqLE_SM", completionHandler: { (connection, result, error) -> Void in
   if (error? != nil){
      NSLog("error = (error)")
   }else{
      println(result)
   }
})

---

更新

以下变化:

FBRequestConnection.startWithGraphPath("(userID)/picture?type=large", completionHandler: { (connection, result, error) -> Void in
  if (error? != nil){
    NSLog("error = (error)")
  }else{
    println(result)
  }
})

回来了:

error = Error Domain=com.facebook.sdk Code=6 "Response is a non-text MIME type; endpoints that return images and other binary data should be fetched using NSURLRequest and NSURLConnection" UserInfo=0x786d4790

推荐答案

可以使用此代码获得:

    // Get user profile pic
    var fbSession = PFFacebookUtils.session()
    var accessToken = fbSession.accessTokenData.accessToken
    let url = NSURL(string: "https://graph.facebook.com/me/picture?type=large&return_ssl_resources=1&access_token="+accessToken)
    let urlRequest = NSURLRequest(URL: url!)

    NSURLConnection.sendAsynchronousRequest(urlRequest, queue: NSOperationQueue.mainQueue()) { (response:NSURLResponse!, data:NSData!, error:NSError!) -> Void in

        // Display the image
        let image = UIImage(data: data)
        self.imgProfile.image = image  

    }
