在 angular dart 上设置全局 Http 请求标头 [英] Setup global Http request Headers on angular dart
本文介绍了在 angular dart 上设置全局 Http 请求标头的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
如何配置 Http 服务向调用添加标头.
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");
}
}
在应用程序中的最后一行是:
And in the app the last line is:
Injector inj = ngBootstrap(module: new SiteIceiModule());
GlobalHttpHeaders.setup(inj);
但这不起作用.
推荐答案
(我认为)我得到了它:
(I think) I got it working with:
@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,因为调试器没有向我显示该字段,但如评论中所述当我应用 headers.setHeaders
在 MyComponent
中做一个映射时,我得到了我的自定义标头(这就是 Http
对 headers代码>)我使用了
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
