通过 firebase 登录获取更大的 Facebook 图片 [英] Get larger facebook image through firebase login

问题描述

我正在使用 firebase 通过 Facebook 登录用户.这一切都很好，我可以获得用户 FB 个人资料图片，尽管它很小.有人可以告诉我如何获得更大的，我正在使用的代码:

I am using firebase to login a user through facebook. This all works fine and I can get the users FB profile image, although it is to small. Can somebody tell me how to get a larger one, the code I am using:

     override func viewDidLoad() {
            let loginButton = FBSDKLoginButton()
            loginButton.readPermissions = ["public_profile", "email"]
            loginButton.delegate = self
            self.view.addSubview(loginButton) 
        }

func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError?) {

        let credential = FIRFacebookAuthProvider.credentialWithAccessToken(FBSDKAccessToken.currentAccessToken().tokenString)

            FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in
                if let user = FIRAuth.auth()?.currentUser {
                for profile in user.providerData {
                let photoUrl = profile.photoURL?.absoluteString //SMALL IMAGE
                   }
                }
            }
        }

(这是快速完成的)

推荐答案

根据 Facebook 文档 在个人资料图片上，您应该能够通过将 width 和 height 附加到 url 来指定大小:

According to the Facebook documentation on Profile Picture, you should be able to specify the size by appending width and height to the url:

let photoUrl = profile.photoURL?.absoluteString + "?width=(width)&height=(height)"

或通过指定类型:

let photoUrl = profile.photoURL?.absoluteString + "?type=large"
