我已经集成了QuickBlox，一切正常，突然间我遇到了这个错误。我试图了解为什么它来了，但没有得到任何解决方案。
我的代码：
ChatHelper.getInstance().login(user, new QBEntityCallback<Void>() {
@Override
public void onSuccess(Void result, Bundle bundle) {
if(progressDialog!=null)
progressDialog.dismiss();
loginToChat();
android.util.Log.e(TAG, "QB Chat Login successfully");
}
@Override
public void onError(QBResponseException e) {
android.util.Log.e(TAG, "Error Login in Home Screen>>>" +e);
if(progressDialog!=null)
progressDialog.dismiss();
}
});
private void loginToChat() {
if(SharedPrefsHelper.getInstance().getQbUser()!=null){
final QBUser user = SharedPrefsHelper.getInstance().getQbUser();
ChatHelper.getInstance().loginToChat(user, new QBEntityCallback<Void>() {
@Override
public void onSuccess(Void result, Bundle bundle) {
android.util.Log.v(TAG, "Chat login onSuccess()");
}
@Override
public void onError(QBResponseException e) {
android.util.Log.w(TAG, "Chat login onError(): " + e);
}
});
}
}

请指导我如何解决登录问题。
请尝试遵循此步骤，它对我非常有用！希望它对您有所帮助！
首先，您需要在QuickBlox中签名。
QBUser user = new QBUser("username", "password");
QBUsers.signIn(user).performAsync(new QBEntityCallback<QBUser>() {
@Override
public void onSuccess(QBUser qbUser, Bundle bundle) {
Log.e("LOGIN ", "myID =" + qbUser.getId());
}
@Override
public void onError(QBResponseException e) {
Log.e("LOGIN Error", "error..SIGN IN*****");
}
});
然后使用该用户对象创建会话然后登录以聊天服务。
以下是代码：
final QBChatService chatService = QBChatService.getInstance();
final QBUser qbuser = new QBUser("username", "password");
QBAuth.createSession(qbuser).performAsync(new QBEntityCallback<QBSession>() {
@Override
public void onSuccess(QBSession qbSession, Bundle bundle) {
user.setId(qbSession.getUserId());
chatService.login(qbuser, new QBEntityCallback() {
@Override
public void onSuccess(Object o, Bundle bundle) {
}
@Override
public void onError(QBResponseException e) {
}
});
}
@Override
public void onError(QBResponseException e) {
}
});
我正在使用QuickBlox版本3.9.1，这对我有用
java
final QBChatService chatService = QBChatService.getInstance();
final QBUser qbuser = new QBUser("USER_EMAIL", "USER_PASSWORD");
QBAuth.createSessionByEmail(qbuser).performAsync(new QBEntityCallback<QBSession>() {
@Override
public void onSuccess(QBSession qbSession, Bundle bundle) {
qbuser.setId(qbSession.getUserId());
chatService.login(qbuser, new QBEntityCallback() {
@Override
public void onSuccess(Object o, Bundle bundle) {
Log.e(TAG, qbSession.getToken() + " , " + qbuser.getEmail());
}
@Override
public void onError(QBResponseException e) {
}
});
}
@Override
public void onError(QBResponseException e) {
}
});
kotlin
val chatService = QBChatService.getInstance()
val qbuser = QBUser("USER_EMAIL", "USER_PASSWORD")
QBAuth.createSessionByEmail(qbuser).performAsync(object : QBEntityCallback<QBSession> {
override fun onSuccess(qbSession: QBSession, bundle: Bundle) {
qbuser.id = qbSession.userId
chatService.login(qbuser, object : QBEntityCallback<Any> {
override fun onSuccess(obj: Any?, bundle: Bundle) {
Log.e(TAG, qbSession.token + " , " + qbuser.email)
}
override fun onError(e: QBResponseException) {
}
})
}
override fun onError(e: QBResponseException) {
}
})
另一种方法是检查会话参数：
public void loginToChat(final QBUser user, final QBEntityCallback<Void> callback) {
if (qbChatService.isLoggedIn()) {
Log.e(TAG, "ChatService Logged In" + qbChatService.isLoggedIn());
callback.onSuccess(null, null);
，然后从要登录的代码中的任何地方调用此方法：
public void loginChat(int qbUserId) {
// Initialise Chat service
QBSessionParameters sessionParameters = QBSessionManager.getInstance().getSessionParameters();
int user_id = qbUserId;
String password = null;
if (sessionParameters.getSocialProvider() != null && sessionParameters.getSocialProvider().equals(QBProvider.FACEBOOK)) {
password = QBSessionManager.getInstance().getToken();
Log.e(TAG, "Logged in QBUser -> " + user_id + " ->" + password);
} else {
password = sessionParameters.getUserPassword();
Log.e(TAG, "Logged in QBUser -> " + sessionParameters.getUserEmail());
}
final QBUser qbUser = new QBUser();
qbUser.setId(user_id);
qbUser.setPassword(password);
loginToChat(qbUser, new QBEntityCallback<Void>() {
@Override
public void onSuccess(Void aVoid, Bundle bundle) {
Log.e(TAG, "ChatService Logged In" + qbChatService.isLoggedIn());
}
@Override
public void onError(QBResponseException e) {
Log.e(TAG, "Error -> " + e.getMessage());
}
});
}
return;
}
qbChatService.login(user, callback);
}
