AngularJS - 获取所有注册服务的列表? [英] AngularJS - Get List of All Registered Services?

问题描述

我能否在运行时获得所有注册指令、服务、控制器等的列表...?

解决方案

您可以获得每个模块的提供者列表(即服务/指令/控制器/工厂/等)，尽管该列表有点神秘.

假设您有以下内容:

var mod = angular.module('myModule', []);mod.factory('fact1', function($dependency1, $dependency2){ ... });mod.service('serv1', function($dependency3, $dependency4){ ... });mod.controller('ctrl1', function($dependency2, $dependency3){ ... });mod.factory('fact2', function($dependency1, $dependency4){ ... });...

然后 mod 变量将包含一个名为 mod._invokeQueue 的属性，该属性将包含作为该模块一部分的所有提供程序的数组._invokeQueue 看起来像这样:

<预><代码>[['$provide', 'factory', Arguments['fact1', ['$dependency1', '$dependency2', function(){}],['$provide', 'service', Arguments['serv1', ['$dependency3', '$dependency4', function(){}],['$provide', 'controller', Arguments['ctrl1', ['$dependency2', '$dependency3', function(){}],['$provide', 'factory', Arguments['fact2', ['$dependency1', '$dependency4', function(){}]...]

因此您可以在 mod._invokeQueue 中搜索它包含的每个提供程序.

但这只会包含该特定模块的提供者列表.如果您想获得所有依赖模块的列表，您需要遍历 mod.requires 数组.

如果模块有模块级的依赖，像这样:

var mod = angular.module('myModule', ['otherModule1','otherModule2']);

然后 mod 对象也将有一个 mod.requires 数组，其中包含这些模块依赖项的名称，如下所示:

angular.forEach(mod.requires, function(requiredModuleName){//首先通过调用 angular.module() 获取对所需模块的引用var requiredMod = angular.module(requiredModuleName);//requiredMod 将有自己的 ._invokeQueue//requiredMod._invokeQueue 看起来就像上面的 _invokeQueue...//对 _invokeQueue 中的其他提供者做一些事情});

希望有所帮助.

Can I get a list of all registered directives, services, controllers, etc. at runtime . . . ?

解决方案

You can get a list of the providers (ie services/directives/controllers/factories/etc) for each module, although the list is kind of cryptic.

Say you have the following:

var mod = angular.module('myModule', []);
mod.factory('fact1', function($dependency1, $dependency2){ ... });
mod.service('serv1', function($dependency3, $dependency4){ ... });
mod.controller('ctrl1', function($dependency2, $dependency3){ ... });
mod.factory('fact2', function($dependency1, $dependency4){ ... });
...

Then the mod variable will contain an attribute called mod._invokeQueue that will contain an array of all the providers that are part of that module. The _invokeQueue will look something like this:

[
    ['$provide', 'factory', Arguments['fact1', ['$dependency1', '$dependency2', function(){}],
    ['$provide', 'service', Arguments['serv1', ['$dependency3', '$dependency4', function(){}],
    ['$provide', 'controller', Arguments['ctrl1', ['$dependency2', '$dependency3', function(){}],
    ['$provide', 'factory', Arguments['fact2', ['$dependency1', '$dependency4', function(){}]
    ...
]

So you can search through that mod._invokeQueue for each provider that it contains.

But that will only contain the list of providers for that specific module. If you want to get a list of all of the dependent modules, you will need to loop through the mod.requires array.

If the module has module-level dependencies, like so:

var mod = angular.module('myModule', ['otherModule1','otherModule2']);

Then the mod object will also have a mod.requires array that contains the names of those module dependencies, like so:

angular.forEach(mod.requires, function(requiredModuleName){
    // first get a reference to the required module by calling angular.module()
    var requiredMod = angular.module(requiredModuleName);
    // requiredMod will have its own ._invokeQueue
    // requiredMod._invokeQueue will look like the _invokeQueue from above
    ...
    // do something with the additional providers in _invokeQueue
});

Hope that helps.
