我遇到了使用Facebook時將用戶註冊到Parse-Server的問題。Parse-Server Facebook登錄
當用戶點擊註冊與Facebook圖標這個代碼將運行..
ParseFacebookUtils.logInWithReadPermissionsInBackground(LoginRegister.this, permissions, new LogInCallback() {
@Override
public void done(ParseUser user, ParseException err) {
if (user == null) {
MethodContants.showLog(TAG, "Uh oh. The user cancelled the Facebook login.", true);
} else if (user.isNew()) {
MethodContants.showLog(TAG, "User logged in through Facebook", false);
getUserDetailsFromFacebook();
} else {
MethodContants.showLog(TAG, "User logged in through Facebook", false);
Intent intent = new Intent(LoginRegister.this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
startActivity(intent);
}
}
});
我getUserDetailsFromFacebook（）方法看起來像這樣
private void getUserDetailsFromFacebook() {
GraphRequest graphRequest = GraphRequest.newMeRequest(AccessToken.getCurrentAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject jsonObject, GraphResponse response) {
try {
facebookUser = jsonObject.getString("name");
MethodContants.showLog(TAG, "json name object: " + jsonObject.getString("name"), false);
} catch (JSONException e) {
MethodContants.showLog(TAG, "Error when getting facebook name: " + e.getMessage(), true);
showToast("Error saving Facebook user.");
}
try {
facebookEmail = jsonObject.getString("email");
MethodContants.showLog(TAG, "json email object: " + jsonObject.getString("email"), false);
} catch (JSONException e) {
MethodContants.showLog(TAG, "Error when getting facebook email: " + e.getMessage(), true);
showToast("Error saving Facebook email.");
}
saveNewFacebookUser();
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "name,email");
graphRequest.setParameters(parameters);
graphRequest.executeAsync();
}
我saveNewFacebookUser（）看起來是這樣的...
private void saveNewFacebookUser() {
final ParseUser newFacebookUser = new ParseUser();
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.profile_picture);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] image = stream.toByteArray();
ParseFile file = new ParseFile(AppConstants.PARSEUSER_IMAGE_FILE_NAME, image);
newFacebookUser.setUsername(facebookUser);
newFacebookUser.setEmail(facebookEmail);
newFacebookUser.put(AppConstants.PARSEUSER_FULLNAME, facebookUser);
newFacebookUser.put(AppConstants.PARSEUSER_FIRST_TIME_LOGGED_IN, "true");
newFacebookUser.put(AppConstants.PARSEUSER_PROFILE_IMAGE, file);
file.saveInBackground(new SaveCallback() {
@Override
public void done(ParseException e) {
if (e == null) {
newFacebookUser.saveInBackground(new SaveCallback() {
@Override
public void done(ParseException e) {
if (e == null) {
// USER CREATED!
// TODO SEND AN EMAIL TO THE USER WITH USERNAME AND PASSWORD
Intent intent = new Intent(LoginRegister.this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
startActivity(intent);
} else {
MethodContants.showLog(TAG, "Facebook Error:" + e.getMessage(), true);
showToast("Facebook Error: " + e.getMessage());
}
}
});
} else {
MethodContants.showLog(TAG, "Facebook Error:" + e.getMessage(), true);
showToast("Facebook Error: " + e.getMessage());
}
}
});
}
錯誤告訴我，我必須使用sig nUpInBackground而不是saveInBackground。但是，當我這樣做，我得到另一個錯誤，說我需要爲用戶保存一個密碼 - >這挫敗了Facebook登錄的全部目的。
任何幫助將不勝感激！
