【问题描述】：

我正在尝试使用 Drive.Files.Create api 上传文件。它运行良好，但在 10-15 请求后突然出现 SocketTimeOut 异常。

drive = new Drive.Builder(httpTransport, JSON_FACTORY, credential).setApplicationName(
              APPLICATION_NAME).build();
Drive.Files.Create insert = drive.files().create(fileMetadata, mediaContent);
insert.setUseContentAsIndexableText(true);
File f=insert.execute();

异常堆栈跟踪：

使用限制：

查询

请求/天 1,000,000,000 的第 20 天

请求数/100 秒/用户 1,000

有什么想法吗？？

【解决方案1】：

下面的东西起作用了

    Drive drive = new Drive.Builder(this.httpTransport, this.jsonFactory, this.credential).setHttpRequestInitializer(new HttpRequestInitializer() {@Override
            public void initialize(HttpRequest httpRequest) throws IOException {

                credential.initialize(httpRequest);
                httpRequest.setConnectTimeout(300 * 60000);  // 300 minutes connect timeout
                httpRequest.setReadTimeout(300 * 60000);  // 300 minutes read timeout
}
}).setApplicationName("My Application").build();

【解决方案2】：

SocketTimeoutException: Read timed out 可以通过定义连接超时或调整超时屏障来解决，以便在网络延迟上更加灵活。除此之外，您还可以检查导致网络延迟的原因，因为据我所知，这种错误是网络连接问题而不是编程问题。

可以在java.net.SocketTimeoutException – How to Solve SocketTimeoutException 中找到有关此类错误的完整说明，此 SO 帖子 - Getting java.net.SocketTimeoutException: Connection timed out in android 也可能有所帮助。
