我将我的应用程序升级到Durandal 2.0。我的应用程序是在HotTowel之后建模的,带有main.js和shell.js。我认为shell.js会在每个视图上运行,但事实并非如此。我的shell.js包含我的安全代码,当然必须在每个视图上运行。我如何强制shell.js在每个视图上运行?
以下是main.js的摘录 -
define(['durandal/app', 'durandal/viewLocator', 'durandal/system', 'plugins/router', 'services/logger'],
function (app, viewLocator, system, router, logger) {
system.debug(true);
app.configurePlugins({
router: true,
dialog: true,
widget: {
kinds: ['expander']
}
});
app.start().then(function () {
toastr.options.positionClass = 'toast-bottom-right';
toastr.options.backgroundpositionClass = 'toast-bottom-right';
viewLocator.useConvention();
router.makeRelative({ moduleId: 'viewmodels' });
// Adapt to touch devices
//Show the app by setting the root view model for our application.
app.setRoot('viewmodels/shell');
return router.map([
{ route: 'home', moduleId: 'home', title: 'home', title: 'Home', nav: true },
{ route: 'CAApproval', moduleId: 'CAApproval', title: 'CA Approval', nav: true }
]).activate();
});
来自shell.js的摘录 -
define(['durandal/system', 'plugins/router', 'services/logger', 'services/SecurityDataService'],
function (system, router, logger, SecurityDataService) {
var HasAccess = ko.observable();
var test = ko.observable('it works');
router.map('About', 'About', 'About', false);
router.map('Help', 'Help', 'Help', false);
var vm = {
activate: activate,
router: router,
User: ko.observable(),
showAbout: 'About',
showHelp: 'Help',
test: 'itworks'
};
return vm;
function showAbout() {
router.navigate('About'); // should show about view
}
function showAbout() {
router.activate('Help'); // should show about view
}
function activate() {
alert("here");
$.when(
$.ajax({
url: '/api/security/CheckSecurity/',
dataType: 'json',
success: function( data ) {
strHasAccess = "";
if (typeof (data) == "string") {
strHasAccess = $.parseJSON(data);
HasAccess = strHasAccess[0].HasAccess;
vm.User = strHasAccess[0].UserName;
$('#spnUserName').text(vm.User);
} else {
HasAccess = false;
}
return strHasAccess;
},
error: function (data) {
amplify.store("ErrorDetails", data.responseText);
log('Error!', null, true);
//return router.activate('ErrorPage'); // should show details page of a particular folder
}
})
).then(function (HasAccess) {
if (strHasAccess[0].HasAccess == true) {
router.buildNavigationModel();
vm.User = strHasAccess[0].UserName;
router.navigate('home');
}
else {
router.map([
{ route: 'AccessDenied', moduleId: 'AccessDenied', title: 'AccessDenied', title: 'AccessDenied', nav: true }
]).activate
router.navigate('AccessDenied');
log('Access Denied!', null, true);
}
});
}
function log(msg, data, showToast) {
logger.log(msg, data, "shell.js", showToast);
}
});

Shell组成一次,当您从一个视图导航到另一个视图时,视图将注入到shell中。在导航到视图之前检查某些条件的一种方法是使用保护路径。
app.start().then(function() {
viewLocator.useConvention();
app.setRoot('shell/shell', 'entrance');
router.guardRoute = function (instance, instruction) {
//auth check here
};
});
另一种方法可能是在每个视图(模型)中使用canActivate()来检查某些内容,并在不满足条件时将用户发送到其他地方。
