设置全局Http请求角度飞镖的标题

问题描述：

如何配置Http服务添加标头到调用。

How can I configure the Http service adding headers to the call.

我尝试以下

class GlobalHttpHeaders {
  static setup(Injector inj){
    HttpDefaultHeaders http = inj.get(HttpDefaultHeaders);
    http.setHeaders([{"X-Requested-With":"XMLHttpRequest"}], "COMMON");
  }
}

在应用程序中，最后一行是：

And in the app the last line is:

Injector inj = ngBootstrap(module: new SiteIceiModule());
  GlobalHttpHeaders.setup(inj);

但不起作用。

（我认为）我使用它：

@Injectable()
class MyDefaultHeaders extends HttpDefaultHeaders {
  @override
  setHeaders(Map<String, String> headers, String method) {
    super.setHeaders(headers, method);
    //if(method.toUpperCase() == 'POST') {
    headers['X-Requested-With'] = 'XMLHttpRequest';
    //}
  }
}


@NgComponent(selector: 'my-comp', publishAs: 'ctrl', template:
    '<div>My component</div>')
class MyComponent {
  Http http;
  MyComponent(this.http) {
    //http.request('http://www.google.com/');
    var h = http;
        // debugger didn't show http so I filed https://code.google.com/p/dart/issues/detail?id=17486

    Map m = {};
    http.defaults.headers.setHeaders(m, 'GET');
    print(m);
    // prints:
    // {Accept: application/json, text/plain, */*, X-Requested-With: XMLHttpRequest}

  }
}


class MyAppModule extends Module {
  MyAppModule() {

    type(MyComponent);

    type(HttpDefaultHeaders, implementedBy: MyDefaultHeaders);

    init.createParser(this);
  }
}

我无法检查 http 以验证标头，因为调试器没有显示字段，但是在注释
中，当我应用 headers.setHeaders MyComponent 我会得到我的自定义头（这是 Http 与 header ）
我使用 DI 0.0.33 ， Angular 0.9.9

I couldn't examine http to verify the headers because the debugger didn't show me the field but as stated in the comment when I apply headers.setHeaders do a map inside MyComponent I get my custom header (this is what Http does with headers) I used DI 0.0.33, Angular 0.9.9
