Predix种子应用程序-从url中删除散列

Question

我正在使用Predix种子，我试图从URL中删除#，这样

http://localhost:5000/#/dash

变成了

http://localhost:5000/dash

做这件事最好的方法是什么？

seed-app.html页面是我认为可以配置URL结构的地方，它有以下关键元素

...
<!-- app route -->
<link rel="import" href="../../bower_components/app-route/app-location.html">
<link rel="import" href="../../bower_components/app-route/app-route.html">
...
<!-- px components -->
<link rel="import" href="../../bower_components/px-app-nav/px-app-nav.html">
<link rel="import" href="../../bower_components/px-view/px-view.html">

<!-- app-location captures url and assigns _route value -->
          <app-location
            id="carbonLocation"
            route="{{_route}}"
            use-hash-as-path>
          </app-location>

          <!-- /dashboards route and view -->
          <app-route
            route="[[_route]]"
            pattern="/dashboards"
            active="{{_dashboardsActive}}">
          </app-route>
...
 <script>
    Polymer({
      is: 'seed-app',
      properties: {
        routesActive: {
          type: Boolean,
          value: false
        },
...
 // Sets app default base URL for client-side routing
        pathPrefix: {
          type: String,
          value: '#'
        }
      },
      ready: function(){
        this._checkForDefaultRoute();
      },
      _checkForDefaultRoute: function() {
        // set default route to /dashboards
        var l = window.location;
        if((l.hash === "#/" || l.hash === "") && l.pathname === "/") {
          l.hash = "/dashboards";
        }
      }
    });
  </script>

我删除了pathPrefix

pathPrefix: {
   type: String,
   value: ''
}

并将_checkForDefaultRoute函数更改如下

_checkForDefaultRoute: function() {
    // set default route to /runtime
    var l = window.location;
    if((l.hash==="") && l.pathname==="/"){
      l.pathname="/login";
    }
  }

其结果是，我仍然需要使用#作为前缀到达页面。

Answer 2

新版本的predix应用程序不使用散列#。请访问

https://github.com/predixdesignsystem/px-sample-app

一般来说，新的px应用程序版本使用dom-if

 <template is="dom-if" if="{{isEqual(selected,'dashboard')}}" restamp>
   <px-sample-dashboard></px-sample-dashboard>
</template>

哪里

  selected: {
        type: Array,
        value: function() {
          return ["dashboard"];
        }
      },

然后可以使用px-app-nav来选择页面。

  <px-app-nav slot="app-nav" selected-route="{{selected}}"
    items='[{"label": "Dashboard","path": "dashboard","icon": "px-fea:dashboard", "id": "dashboard"}]'>
  </px-app-nav>
