与Java Google Drive SDK SocketTimeoutException on File.insert.execute类似

上传数千个文件，一个接一个，似乎每50个文件中就有一个抛出

on files().insert().execute()

我不确定它“意味着”我在插入文件时遇到此异常。

是否意味着插入请求未得到满足，或者不一定？
是否只是表示客户端在发送插入请求后没有收到Google服务器的回复消息？
当我收到此错误时，我应该exponential back-off and retry吗？

Answer 1

显而易见的是尝试防止超时。我认为没有任何方法可以确定在插入帖子完成之前或之后是否发生了错误。当Drive基础架构中存在内部超时时，获得501响应是很常见的，但您的情况则不同。唯一可以确定的方法是在文件对象上设置私有属性，然后搜索Drive以查看是否存在具有该属性的文件（例如，mygeneratedId = some_random_UUID）。

如果您同时插入数千个文件，可以想象您正在窒息某些资源（套接字，带宽等）。您可能希望尝试稍微限制输入。

Answer 2

我有同样的问题。一种可能的解决方案是增加读取超时：的 Timeouts and Errors

private HttpRequestInitializer setHttpTimeout(final HttpRequestInitializer requestInitializer) { return new HttpRequestInitializer() { @Override public void initialize(HttpRequest httpRequest) throws IOException { requestInitializer.initialize(httpRequest); httpRequest.setConnectTimeout(3 * 60000); // 3 minutes connect timeout httpRequest.setReadTimeout(3 * 60000); // 3 minutes read timeout } }; } ... service = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, setHttpTimeout(credential)).build();

SocketTimeoutException：读取插入到Google云端硬盘时超时 - 是否可以重试？
