java.lang.IllegalArgumentException異常：@url不能與@GET URL中使用（參數＃1）

Question

@GET("user/token/") 
Observable<String> gToken(@Url String url, @Query("usertype") int userType); 

我得到以下錯誤：

的錯誤意味着正是它說，你可以使用GET(...)或@Url上的參數，但不能同時存在。如果您需要使用@Url，請從@GET註釋中刪除該URL。您需要將您在url中的url部分添加到url參數中。

@GET 
Observable<String> gToken(@Url String url, @Query("usertype") int userType);
