我想在我的 retrofit 发布请求中添加一个不记名令牌

Question

I have an app that is to register people into a platform but I get a response of Unauthenticated each time I submit the form data. The form is submitted using an API which requires a bearer token for each post request with the aid of retrofit. I have been out of touch with Java. Note: its just a plain form. No authentication has been implemented in the app.

My ApiClient.java class

public class ApiClient {

    private static Retrofit getRetrofit(){

        HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
        httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

        OkHttpClient okHttpClient = new OkHttpClient.Builder().addInterceptor(httpLoggingInterceptor).build();


        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("xxxxxxxxxxxxx")
                .addConverterFactory(GsonConverterFactory.create())
                .client(okHttpClient)
                .build();

        return retrofit;
    }

    public static UserService getUserService(){
        UserService userService = getRetrofit().create(UserService.class);

        return userService;
    }
}

My UserService.java class

public interface UserService {

    @POST("algonapi/api/enroll_vehicle")
    Call<UserResponse> saveUser(@Body UserRequest userRequest);

}

My saveUser Method

public void saveUser(UserRequest userRequest){
        Call<UserResponse> userResponseCall = ApiClient.getUserService().saveUser(userRequest);
        userResponseCall.enqueue(new Callback<UserResponse>() {
            @Override
            public void onResponse(Call<UserResponse> call, Response<UserResponse> response) {
                if (response.isSuccessful()){
                    Toast.makeText(MainActivity.this, "Registration Successfull! Click on Reset Form to Start a New Enumeration...", Toast.LENGTH_LONG).show();
                }else {
                    Toast.makeText(MainActivity.this, "Registration Failed!", Toast.LENGTH_LONG).show();
                }
            }

            @Override
            public void onFailure(Call<UserResponse> call, Throwable t) {
                Toast.makeText(MainActivity.this, "Registration Failed!" +t.getLocalizedMessage(), Toast.LENGTH_LONG).show();
            }
        });
    }

My UserRequest

public class UserRequest {

Answer 1

Create the OkHttpClient like this

  OkHttpClient okHttpClient = new OkHttpClient.Builder().addInterceptor(new Interceptor() {
        @NotNull
        @Override
        public Response intercept(@NotNull Chain chain) throws IOException {
            Request request=chain.request().newBuilder()
                    .addHeader("Authorization", "Bearer " + token)
                    .build();
            return chain.proceed(request);
        }
    }).build();

Answer 2

If you most of your https requests need authentication then the first answer is perfect but if some of your requests need then you can pass the header to each methods.

public interface UserService {
    @POST("algonapi/api/enroll_vehicle")
    Call<UserResponse> saveUser(
        @Header("Authorization") String token,
        @Body UserRequest userRequest
    );
}

While calling the method simply pass your token along with userRequest.
