Question

这是我针对特定路线的ui-router配置

state('app.merchant', {
                url: '/start/merchant',
                views: {
                    'mainView': {
                        templateUrl: "partials/start_merchant.html"
                    }
                },
                css: ['assets/vendor/bootstrap/dist/css/bootstrap.css','assets/css/styles.css','assets/css/plugins.css'],
                title: 'Buttons',

                resolve: {
                    userRequired: userRequired,
                }

                resolve: loadSequence('flow','angularFileUpload','MerchantWizardCtrl')

            })

问题是，即使页面不符合userRequired要求，也会显示该页面。这是userRequired：

的功能

function userRequired($q, $location, $auth,Account) {
      var deferred = $q.defer();
      if ($auth.isAuthenticated()) {

          Account.getUserStatus()
              .then(function(response){
                if(response.data == true){
                    deferred.resolve();
                }
                  else{
                    deferred.reject();
                }
              })
              .catch(function(response){
                  console.log("Error has occur, Please contact adminstrator");
              });
      } else {
          deferred.resolve();
      }
      return deferred.promise;
    }

如何解决这个问题？谢谢！

修改

loadsequence：

function loadSequence() {
        var _args = arguments;

        return {
            deps: ['$ocLazyLoad', '$q',
            function ($ocLL, $q) {
                var promise = $q.when(1);
                for (var i = 0, len = _args.length; i < len; i++) {
                    promise = promiseThen(_args[i]);
                }
                return promise;

                function promiseThen(_arg) {

                    if (typeof _arg == 'function')
                        return promise.then(_arg);
                    else
                        return promise.then(function () {
                            var nowLoad = requiredData(_arg);
                            //console.log(nowLoad)
                            if (!nowLoad)
                                return $.error('Route resolve: Bad resource name [' + _arg + ']');
                            return $ocLL.load(nowLoad);
                        });
                }

                function requiredData(name) {
                    if (jsRequires.modules)
                        for (var m in jsRequires.modules)
                            if (jsRequires.modules[m].name && jsRequires.modules[m].name === name)
                                return jsRequires.modules[m];
                    return jsRequires.scripts && jsRequires.scripts[name];
                }
            }]
        };
    }

当getUserStatus（）服务抛出异常时（在.catch（）中），并且当Authenticated必须拒绝时，您不会拒绝承诺，请尝试此解决方案：

state('app.merchant', {
    url: '/start/merchant',
    views: {
        'mainView': {
            templateUrl: "partials/start_merchant.html"
        }
    },
    css: ['assets/vendor/bootstrap/dist/css/bootstrap.css','assets/css/styles.css','assets/css/plugins.css'],
    title: 'Buttons',
    resolve: {
        userRequired: userRequired,
        loadSequence: loadSequence('flow','angularFileUpload','MerchantWizardCtrl')
    }
})

function userRequired($q, $location, $auth,Account) {
  return $q(function(resolve, reject) {
    if ($auth.isAuthenticated()) {
        Account.getUserStatus()
            .then(function(response){
              if(response.data == true){
                resolve();
              }
                else{
                reject();
              }
            })
            .catch(function(response){
              console.log("Error has occur, Please contact adminstrator");
              reject()
            });
    } else {
        reject()
    }
  });
}

function loadSequence() {
    var _args = arguments;

    return ['$ocLazyLoad', '$q', function ($ocLL, $q) {
            var promise = $q.when(1);
            for (var i = 0, len = _args.length; i < len; i++) {
                promise = promiseThen(_args[i]);
            }
            return promise;

            function promiseThen(_arg) {

                if (typeof _arg == 'function')
                    return promise.then(_arg);
                else
                    return promise.then(function () {
                        var nowLoad = requiredData(_arg);
                        //console.log(nowLoad)
                        if (!nowLoad)
                            return $.error('Route resolve: Bad resource name [' + _arg + ']');
                        return $ocLL.load(nowLoad);
                    });
            }

            function requiredData(name) {
                if (jsRequires.modules)
                    for (var m in jsRequires.modules)
                        if (jsRequires.modules[m].name && jsRequires.modules[m].name === name)
                            return jsRequires.modules[m];
                return jsRequires.scripts && jsRequires.scripts[name];
            }
        }]
}

将延迟方法更改为Promise A +方法（我推荐这种方式）。
在.catch中添加reject（）
未经过身份验证时拒绝

Answer 2

我认为问题是您正在返回承诺，根据设计，它会允许您的应用在尝试确定<img src="${pageContext.request.contextPath}/photo/place/${place.id}/small">,是否有效时继续加载

因此，不要像使用promise这样的异步方法，只需同步解析该依赖关系，它就会阻止页面加载。

以下是我如何修改UserRequired：

UserRequired

Answer 3

首先，您的配置对象具有两倍相同的属性：

{
    resolve: {userRequired: userRequired}
    resolve: loadSequence('flow','angularFileUpload','MerchantWizardCtrl')
}

你应该有类似的东西：

{
    resolve : {
        userRequired : userRequired,
        loadSequence :    loadSequence('flow','angularFileUpload','MerchantWizardCtrl')
}

此外，您的捕获应该返回被拒绝的承诺

return $q.reject();

如上所述，未经过身份验证时拒绝。您可以在chrome中进行调试，以确保调用所有promise并返回正确的值。
