如何从Angular.js中的另一个模块注入提供程序

Question

Why this example not work? jsfiddle I get error what provider not found.

var m1 = angular.module('m1', [])
    .provider('test', function() {
        return {
            $get: function() {
                return 'Hello from provider';
            }
        }
     });

var m2 = angular.module('m2', ['m1'])
    .config(['test', function(test) {
        alert(test);
    }]);

Answer 1

In the config function you do not have access to it, try using the run method.

var m2 = angular.module('m2', ['m1'])
  .run(['test', function(test) {
    alert(test);
  }]);

What you DO have access to in the config function is the service-provider for test so you could do

var m2 = angular.module('m2', ['m1'])
  .config(['testProvider', function(test) {
    alert(test);
  }]);

This would typically be if you want to provide some sort of configuration to your test-service that would be specific for the m2 module.
