使用 loopj AsyncHttpClient 获取 SocketTimeoutExceptions ...我可以设置超时值吗？

Question

当使用 loopj AsyncHttpClient 库时，我在发出请求时不断收到 java.net.SocketTimeoutExceptions（见下文）。

我可以设置一些超时值吗？

注意：我发布此内容是希望为其他人提供一些帮助。我（愚蠢地）努力寻找解决方案一段时间。

我发现AsyncHttpClient 实际上默认为 10 秒超时。如果您的请求需要更长的时间，您将看到抛出的 SocketTimeoutException。

调整这个非常简单。只需执行以下操作：

final int DEFAULT_TIMEOUT = 20 * 1000;
AsyncHttpClient aClient = new AsyncHttpClient();
aClient.setTimeout(DEFAULT_TIMEOUT);
//... continue as normal

可以在javadoc中查看该方法的详细信息-http://loopj.com/android-async-http/doc/com/loopj/android/http/AsyncHttpClient.html#setTimeout(int)
