android - RxJava 2 Retrofit 和动态 url 以及 @url 注释

Question

我正在尝试为多重调用构建一个接口(interface)。即 http://server.com/firstQuery http://server.com/secondQuery

这是我 retrofit 的rx接口(interface)

public interface RequestInterfaceRx<T> {
    @GET("/")
    Observable<CurrencyOnServerConstruct> register();
    Call<ResponseBody> setUrl(@Url String url);
}

这是我使用的代码

private void setupQuery(){
    RequestInterfaceRx requestInterface = new Retrofit.Builder()
            .baseUrl("http://server.com/v3/")
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
            .addConverterFactory(GsonConverterFactory.create())
            .build().create(RequestInterfaceRx.class);
    requestInterface.setUrl("m");
    requestInterface.register()
            .observeOn(AndroidSchedulers.mainThread())
            .subscribeOn(Schedulers.io())
            .subscribe(this::handleResponse,this::handleError);
}

它并没有像预期的那样真正起作用:)

@GET Observable<CurrencyOnServerConstruct> executeFullUrlCall(@Url String url); 

你就是这样做的
