安卓：Facebook的PublishPermissions无需重新键入密码（使用SUP preSS_SSO时）？ [英] Android: Facebook PublishPermissions without retyping password (when using SUPPRESS_SSO)?
问题描述
行动这个Android应用程序的流量 -
- 在UserX登记在Facebook
- 在UserX授予read_permissions
- 在UserX授予publish_permissions
- 在他的access_token被存储在数据库中。
-
UserX注销
-
UserY寄存器... [遵循相同的步骤]
由于它需要多个用户登录，我需要SUP preSS_SSO（感谢<一href="http://stackoverflow.com/questions/13899955/how-to-disable-single-sign-on-for-facebook-android-app">How禁用单点登录Facebook的Android应用？）。
现在在Facebook的API 3.0，Facebook已经取得了ReadPermissions和PublishPermissions不同。 我成功地要求这两个权限，但它要求用户登录两次（因为SSO是燮pressed，显示的WebView） - 登录的WebView弹出再次 - 用户拥有就摆在他的电子邮件和密码。 我要访问的PublishPermissions，或ReadPermissions（以任意顺序），而不必重新输入自己的密码。
从Java code相关的功能如下所示：
私有静态最后的名单，其中，字符串＆GT; PERMISSIONS = Arrays.asList（user_photos，read_friendlists，电子邮件，publish_actions，publish_stream）;
私人无效的UpdateView（）{
会话会话= Session.getActiveSession（）;
如果（session.isOpened（））{
handleAnnounce（）;
textInstructionsOrLink.setText（ACKNOWLEDGE_USER）;
buttonLoginLogout.setText（R.string.logout）;
buttonLoginLogout.setOnClickListener（新OnClickListener（）{
公共无效的onClick（视图查看）{
onClickLogout（）;
}
}）;
} 其他 {
textInstructionsOrLink.setText（R.string.login）;
buttonLoginLogout.setText（R.string.login）;
buttonLoginLogout.setOnClickListener（新OnClickListener（）{
公共无效的onClick（视图查看）{
onClickLogin（）;
}
}）;
}
}
私人无效onClickLogin（）{
会话会话= Session.getActiveSession（）;
如果（session.isOpened（）及！＆安培;！session.isClosed（））{
Session.OpenRequest openRequest =新Session.OpenRequest（本）.setCallback（statusCallback）;
名单＆LT;字符串＆GT; readPermissions = Arrays.asList（user_photos，电子邮件，read_friendlists）;
openRequest.setPermissions（readPermissions）;
openRequest.setLoginBehavior（SessionLoginBehavior.SUP preSS_SSO）;
session.openForRead（openRequest）;
} 其他 {
Session.openActiveSession（这一点，真，statusCallback）;
}
}
私人无效requestPublishPermissions（会话的会话）{
Log.d（LOG_TAG，请求发布权限......）;
如果（会话！= NULL）{
名单＆LT;字符串＆GT; publishPermissions = Arrays.asList（publish_actions，publish_stream）;
最终诠释REAUTH_ACTIVITY_ code = 100;
Session.NewPermissionsRequest reauthRequest =新Session.NewPermissionsRequest（这一点，publishPermissions）.setRequest code（REAUTH_ACTIVITY_ code）;
reauthRequest.setLoginBehavior（SessionLoginBehavior.SUP preSS_SSO）;
session.requestNewPublishPermissions（reauthRequest）;
}
}
私人无效handleAnnounce（）{
会话会话= Session.getActiveSession（）;
如果（会话== NULL ||！session.isOpened（））{
返回;
}
名单＆LT;字符串＆GT;权限= session.getPermissions（）;
如果（！permissions.containsAll（权限））{
requestPublishPermissions（会议）;
返回;
}
}
您code似乎是美好的，它是一个API的缺陷最近报道：
的https://developers.facebook.com/bugs/268146283318403?browse=search_51235ada57ba59615000124
只是耐心，我已经得到了同样的错误，我们所能做的就是等待一个固定的API。
The flow of action on this android app is -
- UserX registers on facebook
- UserX grants read_permissions
- UserX grants publish_permissions
- His access_token is stored in our database.
UserX logs out
UserY registers ... [follows same steps]
Since it requires login of multiple users I need to SUPPRESS_SSO (thanks to How to disable Single SIgn On for facebook android app?).
Now in facebook API 3.0, Facebook has made ReadPermissions and PublishPermissions different. I am succesfully asking for both the permissions, but it requires the user to login twice (since SSO is suppressed and webview is displayed) - the login webview pops up once again - the user has to put in his email and password. I want to access the PublishPermissions, or the ReadPermissions (in any order) without the user having to retype his password.
Relevant functions from the java code is shown here:
private static final List<String> PERMISSIONS = Arrays.asList("user_photos", "read_friendlists", "email", "publish_actions", "publish_stream");
private void updateView() {
Session session = Session.getActiveSession();
if (session.isOpened()) {
handleAnnounce();
textInstructionsOrLink.setText(ACKNOWLEDGE_USER);
buttonLoginLogout.setText(R.string.logout);
buttonLoginLogout.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
onClickLogout();
}
});
} else {
textInstructionsOrLink.setText(R.string.login);
buttonLoginLogout.setText(R.string.login);
buttonLoginLogout.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
onClickLogin();
}
});
}
}
private void onClickLogin() {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
Session.OpenRequest openRequest = new Session.OpenRequest(this).setCallback(statusCallback);
List<String> readPermissions = Arrays.asList("user_photos", "email", "read_friendlists");
openRequest.setPermissions(readPermissions);
openRequest.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);
session.openForRead(openRequest);
} else {
Session.openActiveSession(this, true, statusCallback);
}
}
private void requestPublishPermissions(Session session) {
Log.d(LOG_TAG, "Requesting Publish Permissions...");
if (session != null) {
List<String> publishPermissions = Arrays.asList("publish_actions", "publish_stream");
final int REAUTH_ACTIVITY_CODE = 100;
Session.NewPermissionsRequest reauthRequest = new Session.NewPermissionsRequest(this, publishPermissions).setRequestCode(REAUTH_ACTIVITY_CODE);
reauthRequest.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);
session.requestNewPublishPermissions(reauthRequest);
}
}
private void handleAnnounce() {
Session session = Session.getActiveSession();
if (session == null || !session.isOpened()) {
return;
}
List<String> permissions = session.getPermissions();
if (!permissions.containsAll(PERMISSIONS)) {
requestPublishPermissions(session);
return;
}
}
Your code seems to be fine, it's an API's bug recently reported:
https://developers.facebook.com/bugs/268146283318403?browse=search_51235ada57ba59615000124
Just patience, I've got the very same error and all we can do is wait for a fixed API.
