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

2022-01-21 00:00:00 angularjs javascript ajax angular-ui-router

可通过 API 访问的服务器数据库中的示例 slug:

Examples slugs in server database accessible through API:

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

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

scenario 1 : user view & controller : http://localhost/john-smith

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

场景 2: 公司观点 &控制器:http://localhost/microsoft-technologies

scenario 2 : company view & controller : 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 创建一个动态状态.

Now I want to make make a dynamic state based the slug getting from API Call to the server.

我写了一个虚构的代码.但我没有办法实现

I written a imaginary code. But I'm not getting way to achieve 

// 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 
        }
    }    
})

推荐答案

有一个 一个工作的 plunker.

它来自类似的问题:AngularJS ui-router - 两个相同的路由组

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

In case, I do understand your aim properly, this would be the adjusted state definition (I just skipped the $http and server response part, just working with passed parameter):

.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
        }
      ]
    }
})

一个变化是 resolove : {} 变成了:resolve : {}.另一个是控制器def(rt vs type)的夹具.而且，我们确实从内置功能 templateProvider 和 $templateRequest (类似:Angular ui.router 重新加载父模板提供者)

One change is the resolove : {} became: resolve : {}. Another is fixture of the controller def (rt vs type). And also, we do profit from built in features templateProvider and $templateRequest (similar here: Angular ui.router reload parent templateProvider)

检查实际情况这里

EXTEND，包括 $http 部分(扩展插件)

EXTEND, including the $http part (extended plunker)

让我们调整(出于 plunker 目的)服务器部分以将此信息返回为 data.json:

Let's adjust (for plunker purposes) the server part to return this info as data.json:

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

还有这些链接:

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

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

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

通过这个调整后的状态def可以轻松管理:

Will be easily managed by this adjusted state def:

  .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
            })
        }
      ]
    }
  })
