使用 OkHttp 库，应用程序面临以下 SocketTimeoutException 问题。如果请求大小更小，那么它工作正常(小于 1MB)。我在 10 秒内收到此异常，即使我的套接字超时 (readTimeout) 值要高得多。请求始终失败(大小为 1.8MB)。当我使用 HttpUrlConnection 执行请求时，它工作正常。失败的可能原因是什么？

最佳答案
对于 OkHttp 3，OkHttp 的默认值为 10 秒。您可以将超时时间增加到 30 秒。
OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(30, TimeUnit.SECONDS); // connect timeout
client.setReadTimeout(30, TimeUnit.SECONDS); // socket timeout
