How can I configure the Http service adding headers to the call.
I try the following
class GlobalHttpHeaders {
static setup(Injector inj){
HttpDefaultHeaders http = inj.get(HttpDefaultHeaders);
http.setHeaders([{"X-Requested-With":"XMLHttpRequest"}], "COMMON");
}
}
And in the app the last line is:
Injector inj = ngBootstrap(module: new SiteIceiModule());
GlobalHttpHeaders.setup(inj);
But that don't work.
(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);
}
}
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
@Injectable() on the MyDefaultHeaders.I'm a little late to the discussion, but the answer provided was not usable for me, as my http requests are made by a 3rd party library. But I figured out a way to change the default headers.
You can access and modify the HttpDefaultHeaders object like a map.
headers['Common'].addAll({'Authorization': 'Basic $auth', 'X-Testing': 'Testing'});
This also works with 3rd Party libraries like hammock.
Note: I used angular 1.1.1 I don't know in which version this was added.
Have you tried something like this:
class SiteIceiModule extends Module {
SiteIceiModule() {
// ...
factory(HttpDefaultHeaders, (inj) => inj.get(HttpDefaultHeaders)..setHeader({...}));
// ...
}
}
Illegal argument(s): Cannot resolve a circular dependency! (resolving BlockCache -> Http -> HttpDefaults -> HttpDefaultHeaders -> HttpDefaultHeaders)
