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

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

一个接一个地上传数千个文件似乎每50个文件中就有1个抛出

我不确定在插入文件时我的“异常”是什么.

>这是否意味着插入请求未得到满足,或者不一定？
>它是否仅仅意味着客户端在发送插入请求后没有收到来自Google服务器的回复信息？
>当我收到此错误时,我应该进行指数退避并重试吗？

最佳答案 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).

如果你同时插入数千个文件,可以想象你正在窒息一些资源(套接字,带宽等).您可能希望尝试稍微限制输入.
