任何帮助将不胜感激。
【问题讨论】：
-
您的连接出现超时异常。在 postman 中测试 api 调用，看看它是否有效
-
是的，我知道我遇到了超时异常。我想在我的 Rx 代码中处理它。我期待订阅方法的可抛出调用中的每个错误。但是为什么这个会崩溃而不是去订阅 throwable 调用。
-
你确定你在 RestAdapter.java:395 正确调用 onError 吗？
-
RestAdapter.java 在 Retrofit 库中！我无法控制它。我不想在那里做任何事情。无论 Retrofit 抛出哪个异常，我都想在我的代码中处理它。我在 Rx 代码中做错了什么。这就是我需要找到的。有什么帮助吗？
-
您的问题出在 getChartStockData。那就是你抛出异常的地方。您需要通过调用错误函数、重试或任何其他有意义的行为来捕获并处理它。没有该代码就无法提供进一步的帮助
