Question

我在Unity 3D上获得facebook名称时出错，这个功能明显在2周前工作，

FB.Init（this.InitCallback，this.OnHideUnity）;

private void InitCallback ()
{
    if (FB.IsInitialized) {

        if (FB.IsLoggedIn) {

           FB.LogInWithReadPermissions(new List<string>() { "public_profile","email" }, this.AuthCallback);

        } else {
        }
    } else {

        Debug.Log("Failed to Initialize the Facebook SDK");
    }
}

 private void AuthCallback (ILoginResult result) {
    if (FB.IsLoggedIn) {

        FB.API("/me?fields=name", HttpMethod.GET, this.LoginCallback2);

    } else {
        //Debug.Log("User cancelled login");
    }
}
void LoginCallback2(IResult result)
{
    if (result.Error != null) {

        Debug.Log(result.Error);

    }
    else{
        fbid = result.ResultDictionary ["id"].ToString();
    }
}

我在LoginCallback2函数上遇到错误，调试如下：

UnityEngine.Debug:Log(Object)
connect:LoginCallback2(IResult) (at Assets/connect.cs:983)
Facebook.Unity.<Start>d__9:MoveNext()
UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

简短的回答是，FB尚未初始化，或者用户未登录。下面我分享了自己的代码，用于检索用户的全名及其FBID。在调用此代码部分之前，您需要检查以确保以下内容为真：

FB.IsInitialized == true

和

FB.IsLoggedIn == true

auth = FirebaseAuth.getInstance();
    db = FirebaseDatabase.getInstance();
    ref = db.getReference();
    FirebaseUser user = auth.getCurrentUser();
    uid = user.getUid();//getuser id


    run = (EditText) findViewById(R.id.Run);
    rpw = (EditText) findViewById(R.id.Rpw);
    rage = (EditText) findViewById(R.id.Rage);

    //rbm = (RadioButton) findViewById(R.id.rbmale);
    //rbfm = (RadioButton) findViewById(R.id.rbfemale);

    re = (EditText) findViewById(R.id.Re);
    rpn = (EditText) findViewById(R.id.Rpn);
    ra = (EditText) findViewById(R.id.Ra);
    rpc = (EditText) findViewById(R.id.Rpc);

    //rbstd = (RadioButton) findViewById(R.id.rbstd);
    //rbtt= (RadioButton) findViewById(R.id.rbtt);

    final Button br = (Button) findViewById(R.id.Rbt);

    br.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            usnm = run.getText().toString().trim();
            pswd = rpw.getText().toString().trim();
            email = re.getText().toString().trim();

            ref.child(uid).addValueEventListener(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {
                    Object a = dataSnapshot.getValue();
                }

                @Override
                public void onCancelled(DatabaseError databaseError) {

                }
            });

            if (TextUtils.isEmpty(usnm)){
                Toast.makeText(Register.this, "Username cannot be empty", Toast.LENGTH_SHORT).show();
                return;

            }else if (usnm.length()<8){
                Toast.makeText(Register.this, "Username cannot less then 8 characters", Toast.LENGTH_SHORT).show();
                return;

            }else if (usnm.length()>8){
                Toast.makeText(Register.this, "Username cannot greater then 8 characters", Toast.LENGTH_SHORT).show();
                return;

            }else if (ref.child(uid).child("username").equals(usnm)){
                Toast.makeText(Register.this, "Username had been taken already! Please try another one.", Toast.LENGTH_SHORT).show();
                return;

            }else if (TextUtils.isEmpty(pswd)){
                Toast.makeText(Register.this, "Password cannot be empty", Toast.LENGTH_SHORT).show();
                return;

            }else if (pswd.length()<8){
                Toast.makeText(Register.this, "Password cannot less then 8 characters", Toast.LENGTH_SHORT).show();
                return;

            }else if (pswd.length()>8){
                Toast.makeText(Register.this, "Password cannot greater then 8 characters", Toast.LENGTH_SHORT).show();
                return;

            }else if (TextUtils.isEmpty(email)){
                Toast.makeText(Register.this, "Email cannot be empty", Toast.LENGTH_SHORT).show();
                return;

            }else if (ref.child(uid).child("email").equals(email)){
                Toast.makeText(Register.this, "Email had been taken already! Please try another one.", Toast.LENGTH_SHORT).show();
                return;

            }

            register(usnm, pswd, email);

        }//end of onclick
    });

FB.Api团结错误
