使用rxjava2时Retrofit2未经身份验证的401错误 [英] Retrofit2 Unauthenticated 401 error when using rxjava2
本文介绍了使用rxjava2时Retrofit2未经身份验证的401错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
自从我集成了RxJava2以来，我在返回 Observable 的所有改造调用中都收到401未经身份验证的错误，因此我使用的是基本身份验证，我知道错误是由于此导致的，但是为什么呢?适用于调试但不能发布.
Ever since i'v integrated RxJava2 , i am receiving 401 unauthenticated error in all retrofit calls that return Observable , i'm using basic authentication and i know error is due to it , but why it works on debug but not release.
我认为Retrofit2的rxjava适配器的配置有问题
In my opinion something is wrong with the configuration for rxjava adapters of retrofit2

我正尝试解决此问题超过2周，现在这是我在 rxjava问题页面，而我之前与同一问题相关的问题是
I'm trying to resolve this issue for over a 2 week now here is my post at rxjava issue page and my previous same issue related question is here , how can i resolve this issue and make it working
推荐答案
您的异常发生在您未在此处列出的类中.
Your exception happens in the class which you had not listed here.
无论如何，您需要分析onError处理程序使用的Exception类型.使用Retrofit2 Observables(无论rxjava版本如何)处理有效的HTTP错误响应非常容易.
Anyway, you need to analyze the type of Exception which comes to onError handler. Handling of valid HTTP error responses with Retrofit2 Observables in (regardless of rxjava version) is quite easy.
首先，您需要知道的是，返回Obsrvable<MyObject>的retrofit api方法将仅通过onNext 2xx HTTP响应进行传播.所有其他响应将在onError处理程序中发送.这是如何处理它的代码(Kotlin示例，只是为了给出和想法.Java会这样):
First you need to know is that retrofit api method returning Obsrvable<MyObject> will propagate with onNext only 2xx HTTP responses. All other responses will be sent within onError handler. Here is the code how to handle it (Kotlin example, just to give and idea. Java will ):
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)
}
})
如果希望将所有响应发送到onNext，则应使用Observable<ResponseBody>.在这种情况下，所有有效的HTTP响应都将以onNext结尾，并且所有代码异常都将发送到onError.
If you wish to get all responses into onNext, then you should use Observable<ResponseBody>. In that case all valid HTTP responses will end up in onNext, and all your code exceptions will be sent to onError.
