angularjs – 在启动混合角度1 2应用程序时,如何初始化角度1喷射器？

为了重新创建这个问题,我分叉了Angular Quickstart plunker.

我有这个简单的角度1.x模块：

'use strict';

angular.module('testModule',[])
  .factory('testService',function($q,$log,$interval,$rootScope){
    //Create a service object that we'll build up with methods and eventually
    //return.
    var service = {};
    service.test = 'test';
    return service;
  });

我有这个角度2模块引用角度1.x $注入器来获得角度1.x模块作为提供者：

import { NgModule } from '@angular/core';
import { browserModule } from '@angular/platform-browser';
import { UpgradeModule } from '@angular/upgrade/static';
import { AppComponent } from './app.component';

@NgModule({
  imports: [
    browserModule,UpgradeModule
  ],declarations: [
    AppComponent
  ],bootstrap: [ AppComponent ],providers: [{
    provide: 'testModule',useFactory: (i: any) => i.get('testModule'),deps: ['$injector']
  }]

})

export class AppModule {
  ngdobootstrap() {}
}

我有我的角度2组件,通过依赖注入请求角度1.x模块：

import { Component,Inject } from '@angular/core';

@Component({
  selector: 'my-app',template: `<h1>Hello {{name}},my name is {{myName}}</h1>`
})
export class AppComponent { 
  name = 'Angular'; 
  constructor(@Inject('testModule') testModule: any) {
    this.myName = testModule.test;
  }
}

然后我引导角度2模块和角度1.x模块

import { platformbrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';

platformbrowserDynamic().bootstrapModule(AppModule).then(platformRef => {
  const upgrade = platformRef.injector.get(UpgradeModule) as UpgradeModule;
  upgrade.bootstrap(document.body,['testModule'],{strictDi: true});
});

然后我得到这个错误TypeError：无法读取未定义的属性’get’
    at useFactory是在arrow函数中发生的,该函数指定为我在angular 2模块中提供者定义的“useFactory”属性

providers: [{
    provide: 'testModule',deps: ['$injector']
}]

我认为有一些我不了解如何在混合角度1 2应用中初始化角度1.x喷射器.您可以看到我在通过脚本标记中拉出角度1.x,否则我的角度1.x模块将抛出关于“角度”未定义的错误,我怀疑问题可能与此有关.如果有人能提供指导,我会很感激.

这是调用堆栈的错误：

解决方法

我遇到了同样的问题,并在 github上为我的案例找到了解决方案.
请查看更新的 plunker.请注意,您的代码中还有其他不相关的问题.评论< script src =“test-module.js”>< / script>和testService的隐式注入参数. 希望它会对你有所帮助.
