Retrofit error-Missing either @GET URL or @Url parameter

问题

I am working on Youtube API. The base URL is <https://www.googleapis.com/youtube/v3/search/>

Request :GET

https://www.googleapis.com/youtube/v3/search?part=snippet&q={search_keyword}&key={API_KEY}

ApiService Interface code-

public interface ApiService {
    @GET("")
    Call<YoutubeResponse> searchVideos(@Query("part") String part,
                                   @Query("q") String q,@Query("key") String apiKey);
}

The error: java.lang.IllegalArgumentException: Missing either @GET URL or @Url parameter. in the line of code

Call<YoutubeResponse> call=service.searchVideos("snippet",s, URLConstants.Youtube_API_KEY);

I'm a beginner. Please help!

回答1:

It's much more semantically correct to use https://www.googleapis.com/youtube/v3/ as your base URL and then declare @GET("search/") on your service method.

That said, if you really want your base URL to be the full path you can use @GET(".") to declare that your final URL is the same as your base URL.
