基于API Ajax调用的slug的Angular UI-Router动态路由。基于slug加载视图

标签: javascript ajax angularjs angular-ui-router

可通过API访问的服务器数据库中的slu ::

{slug: "john-smith",type: "user"}
{slug: "microsoft-technologies",type: "company"}

方案1:用户视图&控制器:http://localhost/john-smith

.state('user', {
    url: '/:user',
    templateUrl: 'partial-user.html',
    controller: 'userCtrl'
})

方案2:公司视图&控制器:http://localhost/microsoft-technologies

.state('company', {
    url: '/:company',
    templateUrl: 'partial-company.html',
    controller: 'companyCtrl'
})

现在我想根据从API调用到服务器的slug来制作一个动态状态。

我写了一个虚构代码。但是我没有办法实现

// Example URL http://localhost/john-smith
.state('hybrid', {
    // /john-smith
    url: '/:slug',
    templateUrl: function () {
        return "partial-"+type+".html"
    },
    controllerProvider: function (rt) {
        return type+'Controller'
    },
    resolove: {
        type: function ($http, $stateParams) {
            $http.get({
                method: "GET",
                url: "http://localhost/api/" + $stateParams.slug
            }).success(function(response, status, headers, config){
                //response = {slug: "john-smith",type: "user"}
                return response.type
            })
            return 
        }
    }    
})

它来自类似的问题:AngularJS ui-router - two identical route groups

如果我确实理解你的目标,这将是调整后的状态定义(我刚刚跳过$ http和服务器响应部分,只是使用传递的参数)

.state('hybrid', {
    // /john-smith
    url: '/{slug:(?:john|user|company)}',
    templateProvider: ['type', '$templateRequest',
      function(type, templateRequest) 
      {
        var tplName = "tpl.partial-" + type + ".html";
        return templateRequest(tplName);
      }
    ],
    controllerProvider: ['type',
      function(type) 
      {
        return type + 'Controller';
      }
    ],
    resolve: {
      type: ['$http', '$stateParams',
        function($http, $stateParams) {
          /*$http.get({
            method: "GET",
            url: "http://localhost/api/" + $stateParams.slug
        }).success(function(response, status, headers, config){
            //response = {slug: "john-smith",type: "user"}
            return response.type
        })*/
          return $stateParams.slug
        }
      ]
    }
})

resolove : {} 变为: resolve : {} 。另一个是控制器def的固定(rt vs type)。此外,我们从内置功能templateProvider$templateRequest (类似于此处:Angular ui.router reload parent templateProvider

中获益

EXTEND,包括$ http部分(extended plunker

让我们调整(用于吸引人)服务器部件,将此信息作为 data.json 返回:

{
 "john-smith": {"type": "user"},
 "lady-ann": {"type": "user"},
 "microsoft-technologies" : {"type": "company" },
 "big-company" : {"type": "company" },
 "default": {"type" : "other" }
}

这些链接:

<a href="#/john-smith">
<a href="#/lady-ann">

<a href="#/microsoft-technologies">
<a href="#/big-company">

<a href="#/other-unknown">

将通过此调整状态def轻松管理:

  .state('hybrid', {
    // /john-smith
    url: '/:slug',
    templateProvider: ['type', '$templateRequest',
      function(type, templateRequest) 
      {
        var tplName = "tpl.partial-" + type + ".html";
        return templateRequest(tplName);
      }
    ],
    controllerProvider: ['type',
      function(type) 
      {
        return type + 'Controller';
      }
    ],
    resolve: {
      type: ['$http', '$stateParams',
        function($http, $stateParams) {
          return $http.get("data.json")
            .then(function(response){
              var theType = response.data[$stateParams.slug]
                  ||response.data["default"]
              return theType.type
            })
        }
      ]
    }
  })
