Use Bearer token with Openapi generator generated dart-dio API client

Question

I have generated dart-dio API client with Openapi generator. I use it to login and obtain Bearer token. Then I call this:

openapi.setBearerAuth('Authorization', 'Bearer: $token');

I am not sure what values exactly should I pass here - that might be the problem. When I use API call for secured endpoint, authorization header is not sent which leads to 401 error.

openapi
.getSomethingApi
          .apiSomethingGet();

But it works when I specify the headers:

openapi
.getSomethingApi
          .apiSomethingGet(headers: {'Authorization': 'Bearer: $token'});

Did I misunderstand using authorization in Openapi generator generated dart-dio code or is there any other mistake I made?

Answer 1

I faced same issue as well, I think the interceptors are not initialized correctly, I end up do like below, put the code in the constructor when initializing the api instance

_apiInstance = openapi.Openapi(
        basePathOverride: "your url",
        interceptors: [
          InterceptorsWrapper(onRequest: (options, handler) {
            options.headers['Authorization'] = 'Bearer $token';
            return handler.next(options);
          })
        ]);

the onRequest method will be trigger in each request, so in the events that the token changed or updated, it will get the latest token
