问题描述
我使用的角度路由段在我的角度应用程序和一个试图从一个JSON饲料配置段。
I am using angular-route-segment in my angular app and an trying to configure the segments from a json feed.
我也有这个问题,因为我无法弄清楚如何注入 $ HTTP
到的app.config
功能。这将失败,未知提供商:$ HTTP
I have having problems with this, because I can't figure out how to inject $http
into the app.config
function. This fails with Unknown provider: $http
myApp.config(["$http", "$routeSegmentProvider", function ($http, $routeSegmentProvider) {
/* setup navigation here calling $routeSegmentProvider.when a number of times */
}
因此,而不是注入$ HTTP到配置
,我也试过注射 $ routeSegmentProvider
到 myApp.run
myApp.run(["$http", "$routeSegment", function($http, $routeSegment) {
/* can use $http here to get data, but $routeSegment is not the same here */
/* $routeSegment does not have the when setup method */
}]);
我也试过
`myApp.run(["$http", "$routeSegmentProvider", function($http, $routeSegmentProvider)`
但我得到未知提供商:$ routeSegmentProviderProvider< - $ routeSegmentProvider
推荐答案
供应商只能在配置阶段,而不是跑阶段注入。相反,如$ HTTP服务将还没有被在配置阶段初始化,并且只会在运行阶段是可用的。
Providers can only be injected in the "config" phase and not the "run" phase. Conversely, a service such as $http will not have been initialized yet in the "config" phase and will only be available in the "run" phase.
一个小窍门来解决,这是定义在父函数范围的变量,这样无论是配置和运行块可以访问它:
A little trick to work around this is to define a variable in the parent function scope so that both the "config" and "run" blocks can have access to it:
var routeSegmentProvider = null;
myApp.config(["$routeSegmentProvider", function ($routeSegmentProvider) {
routeSegmentProvider = $routeSegmentProvider;
}]);
myApp.run(["$http", function($http) {
// access $http and routeSegmentProvider here
}]);
我不知道你是否会遇到试图运行阶段内调用$ routeSegmentProvider.setup(),因为我还没有尝试过的问题。在过去,我能够用同样的方法来注册依赖于一些定制服务,HTTP响应拦截器$ httpProvider。
I'm not sure if you will encounter problems trying to call $routeSegmentProvider.setup() within the run phase as I haven't tried. In the past I was able to use the same technique to register http response interceptors that depend on some custom services with the $httpProvider.
