如何覆盖Google Cloud Tasks Node.js客户端的重试配置

我一直在尝试探索是否有一种方法可以重试

I've been trying explore if there's a way to retry the createTask function. The reason being is because I keep on encountering deadline exceeded error from time to time like so:

错误:4 DEADLINE_EXCEEDED:截止日期在Object.onReceiveStatus(/srv/node_modules/grpc/src/client_interceptors.Object.exports.createStatusError(/srv/node_modules/grpc/src/common.js:91:15)处已超过. js:1204:28)在InterceptingListener._callNext(/srv/node_modules/grpc/src/client_interceptors.js:568:42)在InterceptingListener.onReceiveStatus(/srv/node_modules/grpc/src/client_interceptors.js:618:8)在回调时(/srv/node_modules/grpc/src/client_interceptors.js:845:24)

Error: 4 DEADLINE_EXCEEDED: Deadline Exceeded at Object.exports.createStatusError (/srv/node_modules/grpc/src/common.js:91:15) at Object.onReceiveStatus (/srv/node_modules/grpc/src/client_interceptors.js:1204:28) at InterceptingListener._callNext (/srv/node_modules/grpc/src/client_interceptors.js:568:42) at InterceptingListener.onReceiveStatus (/srv/node_modules/grpc/src/client_interceptors.js:618:8) at callback (/srv/node_modules/grpc/src/client_interceptors.js:845:24)

通过阅读createTask函数背后的代码，我发现默认超时

Reading on the code behind the createTask function, I found out that the default timeout configuration was just 10 seconds.

目前，我已尝试通过以下方法将超时时间延长到30秒(我认为是最大):

At the moment, I have tried to extend the timeout to 30s (which I believe is the maximum) by doing this:

try {
  console.log("Sending task %j", task);
  const callOptions = {
    timeout: 30000
  };
  // Send create task request.
  const [response] = await client.createTask(request, callOptions);
  const name = response.name;
  console.log(`Created task ${name}`);
} catch (error) {
  console.error("CREATE_TASK_ERROR::", error);
}

它似乎起作用了.但是，如果API在30秒之内无法响应，我也想谈一谈.

And it appears that it works. However, I would also like to cover the case if the API wasn't able to respond within 30 seconds.

我尝试了以下代码:

try {
  console.log("Sending task %j", task);
  const callOptions = {
    timeout: 2000, // I've set it to 2 seconds to be able to reproduce the deadline exceeded error easily
    retry: {
      initial_retry_delay_millis: 100,
      retry_delay_multiplier: 1.3,
      max_retry_delay_millis: 60000,
      initial_rpc_timeout_millis: 20000,
      rpc_timeout_multiplier: 1.0,
      max_rpc_timeout_millis: 20000,
      total_timeout_millis: 300000
    }
  };
  // Send create task request.
  const [response] = await client.createTask(request, callOptions);
  const name = response.name;
  console.log(`Created task ${name}`);
} catch (error) {
  console.error("CREATE_TASK_ERROR::", error);
}

但是我看不到createTask被重试.但基于评论此处 ，我们应该能够覆盖默认设置，包括重试.

But I don't see the createTask being retried. But based on the comment here, we should be able to override the default settings including retries.

我做错了什么?请帮忙.

What am I doing wrong? Please help.
