通过firebase登录获取更大的Facebook图像 [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，我可以得到用户FB的个人资料图像，虽然它是小的。有人可以告诉我如何获得一个较大的代码，我使用的代码：

  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 
} 
} 
 
} 
  

（这是在swift中完成的）

解决方案

根据Facebook 文档，您应该可以通过追加 width 和 height 到url：

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

或指定类型：

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




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
                   }
                }
            }
        }

(This is done in swift)

解决方案

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)"

or by specifying the type:

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