Retrofit using saved id in SharedPreference to POST update based on id-CodePudding

I have user id from login saved in shared preference that I want to use for profile update by send POST method to API but getting an error:

Attribute value must be constant

UserService.java:

   GetPrefId callid = new GetPrefId(); //this is the user id source(GetPrefId.java)

   @Headers("Content-Type: application/json")
   @POST("users/update/"   callid)
   Call<UpdateResponse> userUpdate(@Body UpdateRequest updateRequest);

GetPrefId.java:

public class GetPrefId extends AppCompatActivity {

        SharedPrefManager sharedPrefManager = new SharedPrefManager(this);
        private String idPref = sharedPrefManager.getId();

        public static final String prefid() {
                String id = GetPrefId.prefid();
                return id;
        }
}

API endpoint:

apiendpoint.com/users/update/:id

:id is based on saved id in the shared preferences

I don't know any other way to insert the user id to the URL. Thanks for your attention and help

CodePudding user response：

According to retrofit documentation for inserting id in URL do like this @GET("group/{id}/users") Call<List<User>> groupList(@Path("id") int groupId);

CodePudding user response：

You can simply use path to do this, your code will be:

@Headers("Content-Type: application/json")
@POST("users/update/{id}")
Call<UpdateResponse> userUpdate(@Body UpdateRequest updateRequest,@Path("id") int id);

you must pass the user id to userUpdate function when you call it.
