Angularjs UI-Router状态参数不起作用

I have a simple setup in my config()

我的配置中有一个简单的设置()

    $stateProvider
        .state('app', {
          'url': '/app',
          'abstract': true,
          'templateUrl': 'views/layout/index.html',
          'controller': 'App'
        })

        .state('app.home', {
          'url': '/home',
          'views': {
            'appContent': {
              'templateUrl': 'views/home/index.html',
              'controller': 'Home'
            }
          }
        });
        .state('app.asd', {
          'url': '/asd/:idContact?',
          'views': {
            'appContent': {
              'templateUrl': 'views/asd/index.html',
              'controller': 'Asd'
            }
          }
        });
$urlRouterProvider.otherwise('/app/home');

If i browse app/asd/7 everything works if i browse then app/asd it redirects me

如果我浏览app / asd / 7一切正常,如果我浏览app / asd它重定向我

I am wondering how can i make idContact param not required ? I used the classic $routeProvider sintax for it :(

我想知道如何才能使idContact param不是必需的?我使用经典的$ routeProvider sintax :(

2 个解决方案

#1

Try:

/asd/{idContact:/?.*}

As far as I know that is the workaround to make parameters optional in ui router. I'm not sure if there have been any recent built in implementations of this in ui router.

据我所知,这是在ui路由器中使参数可选的解决方法。我不确定ui路由器中是否有最新的内置实现。

Just wanted to provide some example giving the answer to optional parameter issue. See that all in working example.

只想提供一些示例,给出可选参数问题的答案。在工作示例中查看所有内容。

此问答确实解释了更多细节:

Here is a snippet of two states definition:

以下是两个州定义的片段:

.state('view', {
    url: '/view/:inboxId',
    templateUrl: 'tpl.view.html',
    controller: 'viewCtrl'
}).

state('view_root', {
    url: '/view',
    templateUrl: 'tpl.view.html',
    controller: 'viewCtrl'
})

And here are some ways how to create links (href or ui-sref) to reach these states:

以下是一些如何创建链接(href或ui-sref)以达到这些状态的方法:

// href
<a href="#/view/1">/view/1</a> - id is passed<br />
<a href="#/view/"> /view/ </a> - is is missing - OPTIONAL like <br />
<a href="#/view">  /view  </a> - url matching the view_root

// ui-sref
<a ui-sref="view({inboxId:2})">    - id is passed<br /> 
<a ui-sref="view">                 - is is missing - OPTIONAL like
<a ui-sref="view({inboxId:null})"> - id is explicit NULL <br />
<a ui-sref="view_root()">          - url matching the view_root

That should show, that we do not have to pass some param, just must be sure that the proper url is called (the trailing /)

这应该表明,我们不必传递一些参数,只需要确保调用正确的URL(尾随/)
