Angularjs $location 服务显然没有解析 url? [英] Angularjs $location service apparently not parsing url?

问题描述

我在一个应用程序中使用 angular，它基本上是一个包含搜索结果的表格.可以通过像 http://myapp/?client=clientName

I'm using angular in an application which is, basically, a table with search results. Access to this table can be achieved via an url like http://myapp/?client=clientName

为表格实例化一个角度控制器，除其他外，用于打开带有行详细信息的模式对话框(也是基于角度的引导用户界面).

An angular controller is instantiated for the table, among other things, for opening a modal dialog (also angular-based with bootstrap-ui) with the row details.

这些行细节是通过一项服务提供的，该服务对两个控制器都有一些共同的功能:一个用于表格，另一个用于模态.

These row details are brought via a service which has some common functionality for both controllers: the one for the table and the one for the modal.

现在，在此服务中，我需要检索以下代码段:

Now, within this service, I have the following snippet to retrieve:

service.fetchRelatedElements = function(element, cb) {
  var url = '/search.json?results=20&type='+element.type;
  if ($location.search()['client']) {
    url += '&client=' + $location.search('client');
  }
  return doFetch(url, cb); // actual server json GET
};

目标是知道该表是否已经将这个特定的client 参数设置为过滤器.

The goal is to know if the table already has this specific client parameter set as a filter.

如果我在这个调用的开始处放置一个断点，我会看到 $location.absUrl() 返回当前浏览器 URL(在我的例子中，它有 client 我感兴趣的参数).

If I put a breakpoint at the beginning of this call, I see that $location.absUrl() returns the current browser URL (which, in my case, has the client parameter I'm interested in).

但是 $location.search() 返回一个空对象.

But $location.search() returns an empty object.

我在我的服务中注入了默认值的 $location 服务(也就是说，不是通过 .config() 调用来配置它).而且，正如文档所说:

I am injecting the $location service within my service with the defaults (that is, not configuring it by a .config() call). And, as doc says:

$location 服务解析浏览器地址栏中的 URL(基于在 window.location 上)并使该 URL 可供您使用申请.

The $location service parses the URL in the browser address bar (based on the window.location) and makes the URL available to your application.

我错过了什么吗?不应该在此时解析 URL 吗?

Am I missing something? Shouldn't the URL, at this point, be parsed?

谢谢！

更新:我设法让它发挥作用.问题正是我根本没有配置服务.我这样做是因为我认为那样会采用默认值，但似乎这不是它的工作方式.

UPDATE: I've managed to make it work. The problem was exactly that I wasn't configuring at all the service. I did so because I assumed that in that way it would take defaults, but it seems that that's not the way it works.

推荐答案

在我的应用程序的模块配置中配置 $locationProvider 之前，我遇到了同样的问题:

I was having the same problem before I configured $locationProvider in my app's module config:

appModule.config(['$locationProvider', function($locationProvider) {
        $locationProvider.html5Mode(true);
    }]);
