新的Firebase Facebook登录 [英] New Firebase Facebook login

问题描述

这是Facebook登录的代码

  let facebookLogin = FBSDKLoginManager（）
 facebookLogin.logInWithReadPermissions（[email]，fromViewController：self）{（result，error） - >无效
如果错误！= nil {
 print（error is \（error））
} else {
 let accessToken = FBSDKAccessToken.currentAccessToken（）。tokenString 
 
让凭证= FIRFacebookAuthProvider.credentialWithAccessToken（accessToken）
 
 AUTH？.signInWithCredential（凭证，完成：{（user，error） - >无效
 
 $ if 
 print（error is \（error））
} else {
 print（user）
 NSUserDefaults.standardUserDefaults（）。setValue （user？.uid，forKey：KEY_UID）
 self.performSegueWithIdentifier（SEGUE_LOGGEDIN，sender：nil）
} 
}）
} 
  

这是我得到的错误代码

可选（错误域= FIRAuthErrorDomain代码= 17999内部错误已占有UserInfo = {error_name = ERROR_INTERNAL_ERROR，NSUnderlyingError = 0x79f082b0 {Error Domain = FIRAuthInternalErrorDomain Code = 3（null）UserInfo = {FIRAuthErrorUserInfoDeserializedResponseKey = {type = immutable dict，count = 3 ，

解决方案

请确保您在Firebase控制台中启用了Facebook身份验证。

确保您在Firebase控制台中输入正确的FACEBOOK App ID和App Secret。 （不是您的XCode应用程序ID）

I'm trying to make a Facebook login with the new Firebase platform.

this is the code for the facebook login

let facebookLogin = FBSDKLoginManager()
    facebookLogin.logInWithReadPermissions(["email"], fromViewController: self) { (result, error) -> Void in
        if error != nil {
            print("error is \(error)")
        } else {
            let accessToken = FBSDKAccessToken.currentAccessToken().tokenString

            let credential = FIRFacebookAuthProvider.credentialWithAccessToken(accessToken)

            AUTH?.signInWithCredential(credential, completion: { (user, error) -> Void in

                if error != nil {
                    print("error is \(error)")
                } else {
                    print(user)
                    NSUserDefaults.standardUserDefaults().setValue(user?.uid, forKey: KEY_UID)
                    self.performSegueWithIdentifier(SEGUE_LOGGEDIN, sender: nil)
                }
            })
        }

and this is the error code i get

Optional(Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and inspect the error details for more information." UserInfo={error_name=ERROR_INTERNAL_ERROR, NSUnderlyingError=0x79f082b0 {Error Domain=FIRAuthInternalErrorDomain Code=3 "(null)" UserInfo={FIRAuthErrorUserInfoDeserializedResponseKey={type = immutable dict, count = 3, entries =>

0 : {contents = "errors"} = {type = immutable, count = 1, values = (

0 : {type = immutable dict, count = 3, entries =>

0 : {contents = "reason"} = {contents = "invalid"}

1 : {contents = "message"} = {contents = "Unsuccessful debug_token response from Facebook: {"error":{"message":"Invalid OAuth access token signature.","type":"OAuthException","code":190,"fbtrace_id":"BrewfOSy/fH"}}"}

2 : {contents = "domain"} = {contents = "global"} }

)}

1 : {contents = "code"} = {value = +400, type = kCFNumberSInt64Type}

2 : {contents = "message"} = {contents = "Unsuccessful debug_token response from Facebook: {"error":{"message":"Invalid OAuth access token signature.","type":"OAuthException","code":190,"fbtrace_id":"BrewfOSy/fH"}}"}

}

}}, NSLocalizedDescription=An internal error has occurred, print and inspect the error details for more information.})

解决方案

Make sure you enable Facebook authentication in your firebase console.

Make sure you enter the correct FACEBOOK App ID and App Secret in the firebase console. (Not your XCode App ID)
