本文整理了Java中com.google.gwt.user.client.History.getToken()方法的一些代码示例，展示了History.getToken()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。History.getToken()方法的具体详情如下：
包路径：com.google.gwt.user.client.History
类名称：History
方法名：getToken

History.getToken介绍

[英]Gets the current history token. The handler will not receive a ValueChangeHandler#onValueChange(com.google.gwt.event.logical.shared.ValueChangeEvent)event for the initial token; requiring that an application request the token explicitly on startup gives it an opportunity to run different initialization code in the presence or absence of an initial token.
[中]获取当前历史标记。处理程序不会收到初始令牌的ValueChangeHandler#onValueChange（com.google.gwt.event.logical.shared.ValueChangeEvent）事件；要求应用程序在启动时显式请求令牌，使其有机会在存在或不存在初始令牌的情况下运行不同的初始化代码。

代码示例

  1. private void processHistory(ValueChangeEvent<String> event) {
  2.  String historyToken;
  3.  if (event != null) {
  4.   historyToken = event.getValue();
  5.  } else {
  6.   historyToken = History.getToken();
  7.  }
  8.  updateHistoryParamsFromToken(historyToken);
  9. }

代码示例来源：origin: kaaproject/kaa

  1. @Override
  2. public void onModuleLoad() {
  3.  HistoryHandler historyHandler = new HistoryHandler();
  4.  History.addValueChangeHandler(historyHandler);
  5.  updateHistoryParamsFromToken(History.getToken());
  6.  authService.checkAuth(new AsyncCallback<AuthResultDto>() {
  7.   @Override
  8.   public void onFailure(Throwable caught) {
  9.    authResult = Result.ERROR;
  10.    showLogin();
  11.    Utils.handleException(caught, view);
  12.   }
  13.   @Override
  14.   public void onSuccess(AuthResultDto result) {
  15.    authResult = result.getAuthResult();
  16.    if (authResult == Result.OK) {
  17.     redirectToModule("kaaAdmin");
  18.    } else {
  19.     showLogin();
  20.     if (authResult == Result.ERROR) {
  21.      view.setErrorMessage(Utils.messages.unexpectedError());
  22.     } else if (authResult == Result.KAA_ADMIN_NOT_EXISTS) {

  24.     }
  25.    }
  26.   }
