interface CommentService {    // Post comment in a post by Profile ID and Post ID    @POST("/comment/{user_id}/{post_id}")    fun postCommentByPostId(@Path("post_id") postId: Long, @Path("user_id") userId: Long,                            @Query("commentText") commentText: String): Observable<Post>    // Delete comment in a post by Profile ID and Post ID    @DELETE("/comment/{user_id}/{post_id}")    fun deleteCommentByPostId(@Path("post_id") postId: Long, @Path("user_id") userId: Long, @Query("commentText") commentText: String): Observable<Post> ...
