error TS2322: Type 'Response' is not assignable to type 'string'. about angular2-jwt HOT 9 CLOSED

that's not specific to angular2-jwt, it's a plain angular2 http topic. Check first example here: https://angular.io/docs/js/latest/api/http/Http-class.html

@slintes I saw the angular2-jwt code , the _request just merge HttpOptions, with response ,do nothing with jwt?
what is angular2-jwt do ? I dont understand

angular2-jwt checks if you have a valid jwt token, and if so it adds it to the header of the http request. It's just a wrapper around angular2's http module, with some extras.
On server side you have to also check if the token is valid, and if the user is allowed to access the requested resource. I don't know jjwt, so I don't have example code.
Probably you want your server to return some json data. If so, you can use Response.json() in the subscribe() method, in order to map json to whatever type. See link in my response above to see how to do that...

when I frist enter my app , have not jwt token in headers.
so , when I use authHttp do something, will throws exception , so I need set noJwtError : true ,
but I after first request then server response a string (this is a jwt token?I use jwtHelper.decodeToken can found real value ),and I need the put this string on localStorge['id_token']?

and next time I use authHttp to request(post、get、delete or something else method) server , I need read the 'Authorization' in request headers? and verify the token ?

it that the process working with jwt ?

sorry ! my english no good , can U understand what I mean ?

AuthHttp is for sending requests with your JWT token, it does not handle fetching the token and saving it in local storage. You should use regular Http requests to get your token, and then save the token in local storage where AuthHttp will find it.

To your initial comment, about the type of the object you get back: It will always be a response object, which has fields for getting headers, status codes, etc... If you want to get the actual payload you need to do response.text() or response.json(). Typings don't exist at runtime and it won't coerce stuff into say, strings or objects for you. You should always set your types based on what they actually are/will be at run time and not what you think they are.

that mean I need use Http to get a authorization，and this authorization is that jwt?
and I need save it in local storage with name 'id_token'(or just other name).
then I can use authHttp to do request thing,and they will use JWT token all the time?
so , in addition to login action,after authorization action alway need verify the token by request headers?

Thanks @slintes and @escardin :)

@forfuns that's correct, you need to have your server set up to issue a JWT when the user logs in and then store it in local storage. That is done using the regular Http class. Then you can use AuthHttp and the JWT will be sent as an Authorization header automatically to access protected resources. :)
