I have a GET request like this http://176.57.71.76/api/user_vacancy?employment=full_time&time=7&house=0&sort=name
but, sometimes I do need to put query parameters employment, time and so on.
Now, I have this
@GET("user_vacancy")
fun getVacanciesWithFilter(): Single<VacanciesListResponse>
Do I need to write a separate request for each parameter, or can I bypass this somehow?
Add your query/filter as per you need
val hashMap = HashMap<String, String>()
hashMap.put("employment", "full_time")
hashMap.put("time", "7")
hashMap.put("house", "0")
hashMap.put("sort", "name")
suppose you do not need house and sort filter then you don't need to put them on hashmap
like,
val hashMap = HashMap<String, String>()
hashMap.put("employment", "full_time")
hashMap.put("time", "7")
then calling your api
apiService.getVacanciesWithFilter(hashMap)
In your API service class
@GET("user_vacancy")
fun getVacanciesWithFilter(
@QueryMap hashMap: Map<String, String>
): Single<VacanciesListResponse>
You don't have to write separate code for each query parameter. Retrofit supports optional query parameters. Here is the Java code for your example. If you pass null for any parameter, Retrofit will omit that query while forming the request.
@GET("user_vacancy") Single<VacanciesListResponse> getVacanciesWithFilter(
@Query("employment") String employmentType,
@Query("time") int time
);
More info here. Using QueryMap is also a good approach as mentioned in another answer.
