Where to set responseType to http GET for HttpClient in angular
I have a service that makes an http call to my backend:
exportSubs(param: Param): Observable<Sub>
return this.http.get<Sub>(
`$environment.apiBaseUrl/blah`,
headers: this.httpUtil.getReqHeaders)
.catch(error => this.httpUtil.handleError(error));
where do I set responseType?
@mast3rd3mon that's absolutely not what you normally do! Do you mean in the same object as the headers?

Did you read the docs? They show exactly where to set it.

@jonrsharpe yes it is what you do, its the
Accept header, unless he means what the angular http response type is, in which case it is already set to an array of Sub– mast3rd3mon

Accept
Sub
@mast3rd3mon I think you misunderstand the question, I'd suggest also reading the docs I just linked.

You can specify that the data to be returned is not a JSON using the responseType. See the Requesting non JSON data
responseType
In your example, you should be able to use:
return this.http.get(
`$environment.apiBaseUrl/blah`, responseType: 'text' )
EDIT
You can set the responseType as blob,
return this.http.get(`$environment.apiBaseUrl/blah`, responseType: 'blob' );
That's not even valid syntactically, so I doubt you tried it.

@Drew13 sounds like youre passing an extra parameter into the call,
get methods only take 2 paramaters, the url and optional http options– mast3rd3mon

get
@mast3rd3mon yeah I had to get rid of where I set my headers. I need my responseType to be of type 'blob'. I'll just figure it out
