Angular 2 AuthHttp with jwt not connecting - api

Question

I'm trying to use jwt's authHttp to set an API connection to a particular Back End. I'm trying to make it first without any token so I can test it but it seams like it's not even getting connected. I'm using it as following:
this.authHttp.get('localhost:3001/api/basic')
.subscribe(
data => console.log("data"),
err => console.log(err),
() => console.log('Request Complete')
);
The error I'm getting in the console is AuthHttpError {}
I've set my ngModules as it say in the guide:
providers: [
{
provide: AuthHttp,
useFactory: authHttpServiceFactory,
deps: [Http, RequestOptions]
}
And
function authHttpServiceFactory(http: Http, options: RequestOptions) {
return new AuthHttp(new AuthConfig({noTokenScheme : true}), http);
}
The thing that drive's me crazy is that using http it works fine like this:
this.http.get('http://localhost:3001/api/basic').subscribe(
data=> console.log(data),
error=> console.log("Getting Error")
);
You are probably thinking "Why he is not using http then instead of authHttp?". Well, that's because setting a heather "Authorization" and its token seams impossible with http.
Any help or guidance would be extremely helpful.

If you don't need JsonWebTokens but simply want to add custom headers, you can do it this way without having to import the angular2-jwt library :
In your service :
private customHeaders: Headers = this.setCredentialsHeader();
setCredentialsHeader() {
let headers = new Headers();
let credentials = window.localStorage.getItem('credentials2');
headers.append('Authorization', 'Basic ' + credentials);
return headers;
}
someMethod() {
let url = 'your.URL.to.API';
return this.http
.get(url, { headers: this.customHeaders })
.map(result => {
console.log(result);
});
}
This way you can add your Authorization header with the type of data you want.
If it's a Authorization Bearer type header you are looking for and use it with angular2-jwt, you can use the default configuration first before trying to provide your own AuthHttp instance through the factory. It will be much simpler to debug and figure where the problem is.
From the documentation : https://github.com/auth0/angular2-jwt#configuration-options
AUTH_PROVIDERS gives a default configuration setup:
In your module with your service, just import the AUTH_PROVIDERS like this :
import { AUTH_PROVIDERS } from 'angular2-jwt';
...
#NgModule({
...
providers: [
AUTH_PROVIDERS,
...
]
})
and simply use the AuthHttp instance in your service like you did.
You should see in the Navigator Network tab your headers being added to your request.
EDIT :
As stated in the documentation, it is appending the token value in the headers from the Token Getter Function defined in the AUTH_PROVIDERS by default.
You therefore need to add your JWT in your LocalStorage with the default name id_token.
To give you my working example, I'm setting a JWT upon the authentication process, where I get a JWT as a response from my Http Call :
auth.service.ts
this.identityService.setToken(token.accessToken);
identity.service.ts
setToken(token?) {
if (token) {
window.localStorage.setItem('id_token', token);
} else {
window.localStorage.removeItem('id_token');
}
}
You should be able to see your JWT in your network tab if done correctly.
Afterwards, the AuthHttp instance should add the headers to your requests as intended...
It might not work correctly if your Token is not a JWT. To check if it's a good one, you can use a website such as https://jwt.io/ where it will be decoded.
If it's still not working, this means the problem is coming from elsewhere. A service not provided correctly, etc.
