我使用rx-android
进行改装2我有非常复杂的重试逻辑,部分工作。我切断了不相关的代码来简化它。这是:
public class RetryWithDelay implements Func1<Observable<? extends Throwable>, Observable<?>>, Constants {
@Override
public Observable<?> call(Observable<? extends Throwable> attempts) {
return attempts.flatMap(new Func1<Throwable, Observable<?>>() {
@Override
public Observable<?> call(Throwable throwable) {
int statusCode = 500;
if (throwable instanceof HttpException) {
HttpException httpException = (HttpException) throwable;
statusCode = httpException.code();
}
boolean shouldRetry = shouldRetry();
if (shouldRetry && statusCode == 401 && requiresAuthorization) {
LoginProvider provider = AppUtils.getExternalProvider(context);
switch (provider) {
case GOOGLE:
return reauthorizeGoogleProvider();
case FACEBOOK:
return reauthorizeFacebookProvider();
default:
return reauthorizeApiProvider();
}
} else if (shouldRetry) {
return Observable.timer(Configuration.REQUEST_RETRY_DELAY_IN_SECONDS, TimeUnit.SECONDS);
} else {
return Observable.error(throwable);
}
}
});
}
我有网络调用observable,它会抛出401.然后触发重试逻辑。电话看起来像
observable
.subscribeOn(Schedulers.newThread())
.retryWhen(new RetryWithDelay(getActivity()))
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<MyArticles>() {
//code removed for simplicity
});
当我得到401 RetryWithDelay开关时,触发三种方法之一。 当用户在我的api中本地登录时,它可以正常工作,该API调用:
private Observable<?> reauthorizeApiProvider() {
return retrofitService.loginWithRefreshToken(data).flatMap(new Func1<User, Observable<?>>() {
@Override
public Observable<?> call(User user) {
app.setUserInfo(UserInfo.fromUser(user));
AppUtils.saveUserData(context, user);
return Observable.timer(0, TimeUnit.MICROSECONDS);
}
});
}
但对于Facebook或谷歌最终会出现神秘异常:java.io.InterruptedIOException: thread interrupted
。这就是我为谷歌做的方式 - 对于Facebook也一样。
private Observable<?> reauthorizeGoogleProvider() {
return retrofitService.loginWithExternalProvider(LoginProvider.GOOGLE, externalAccessToken).flatMap(new Func1<User, Observable<?>>() {
@Override
public Observable<?> call(User user) {
//some irrelevant logic
return Observable.timer(0, TimeUnit.MICROSECONDS);
}
});
}
我传递给改造方法的参数没有任何问题。登录时成功使用具有相同参数的此方法,而不是重试逻辑的一部分。
这是完整的堆栈跟踪:

请告知
编辑:调查显示它以某种方式连接到http方法。loginWithRefreshToken
为POST
,loginWithExternalProvider
为GET
。更改ti POST时工作。但那是愚蠢的。需要真正的解决方案。
