自从我集成了 RxJava2，我在所有返回 Observable 的改造调用中收到 401 unauthenticated 错误，我正在使用基本身份验证，我知道错误是由于它引起的，但为什么会这样适用于调试但不适用于发布。
在我看来，retrofit2 的 rxjava 适配器配置有问题

我已经尝试解决这个问题超过 2 周了，现在这是我在 rxjava issue 上的帖子页面和我之前的相同问题相关的问题是 here , 我怎样才能解决这个问题并使其正常工作
最佳答案
您的异常发生在您未在此处列出的类中。
无论如何，你需要分析Exception的类型这是 onError处理程序。使用 Retrofit2 处理有效的 HTTP 错误响应Observables(无论 rxjava 版本)非常简单。
首先你需要知道的是retrofit api 方法返回 Obsrvable<MyObject>将与 onNext 一起传播只有 2xx HTTP 响应。所有其他回复将在 onError 内发送处理程序。以下是如何处理它的代码(Kotlin 示例，仅供引用。Java 会):
retrofitApiService.suggest(
token,
query).subscribe ({ suggestions ->
log.info("Got result: {}", suggestions)
}, { error ->
//
if(error is HttpException) {
if(error.code() == 401) {
// We've got HTTP 401 Unauthorized
} else {
log.error("HTTP Error: {} {}, {}",
error.response().code(),
error.response().message(),
error.response().errorBody().toString())
}
} else {
// something really wrong happened
// e.g.: invalid json or something else
log.error("Error: ${error.message}", error)
}
})
如果你想让所有的响应都进入onNext，那么你应该使用Observable<ResponseBody> .在这种情况下，所有有效的 HTTP 响应都将以 onNext 结束。 , 你所有的代码异常都将发送到 onError .
关于android - 使用 rxjava2 时出现 Retrofit2 Unauthenticated 401 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41806148/
