我们的集成平台现在每天都会收到几个“无法获取 URL:...”错误。我不知道这是什么原因。

首先,GAE 尝试通过 BigQuery API 从应用程序内部向 BigQuery 授权 OAuth2 .它每秒尝试超过 30 秒(这只是 30 条类似行中的 1 条):

2015-05-12 05:59:02.727
URL being requested: https://www.googleapis.com/bigquery/v2/projects/XXX/jobs/job_w-z5K2zQObXeSaLy3hx7m4FOMXc?alt=json

下面是跟踪本身(就在上面显示的日志之后):

File "/base/data/home/apps/s~XXX/processes:uno.383135852015228853/connectors/connector_XXX_v1_0.py", line 189, in send

'An error occured while connecting to the server: %s' % e)
error: An error occured while connecting to the server: Unable to fetch URL: https://www.googleapis.com/bigquery/v2/projects/XXX/jobs/job_d_ONsjBebYjreJuDD-ZdEqCHYv0?alt=json

这些来自从 Google Datastore 获取数据并加载到 BigQuery 的进程。

这些错误是不确定的。有时它们会发生。有时不要。我在这里看不到任何模式。

需要注意的一件事:直到 2015 年 5 月 1 日,这些流程都没有问题。数据轻松加载到 BQ。

我的假设是它可能以某种方式与 OAuth2.0 相关。我们使用

oauth2client v1.1。最新的是 1.4.7。也许更新会有所帮助?还是问题出在其他地方?

最佳答案

要最大限度地减少此类错误,请在将数据插入 BigQuery 时在您的应用程序中实现重试策略。通过 document为了更好的解释
