如何使用改造和rxjava取消任务 [英] How cancel task with retrofit and rxjava

问题描述

我有休息用的api.

@Get("/serveraction")
public Observable<String> myRequest(@Query("Data") String data);

我知道okhttp具有取消功能(按请求对象，按标签)，但是不知道如何在翻新和rxjava中使用它.用翻新和rxjava实现网络任务取消机制的最佳方法是什么?

I know, that okhttp has canceling functionality(by request object, by tag), but don't know how use it with retrofit and rxjava. What is the best way to realize canceling mechanism for network tasks with retrofit and rxjava?

推荐答案

您可以使用标准的RxJava2取消机制

You can use the standard RxJava2 cancelling mechanism Disposable.

Observable<String> o = retrofit.getObservable(..);
Disposable d = o.subscribe(...);

// later when not needed
d.dispose();

Retrofit RxJava调用适配器会将其重定向到okHttp的取消.

Retrofit RxJava call adapter will redirect this to okHttp's cancel.

RxJava1: RxJava2:
