根因分析

客户端在RPC完成之前取消了上下文，通常是由于用户操作或超时。

English

The client cancelled the context before the RPC completed, often due to user action or timeout.

解决方案

  1. 90% 成功率 Create a new context for each RPC call to avoid using cancelled contexts. 
    ctx := context.Background()
resp, err := client.SomeRPC(ctx, req)
if err != nil {
    if status.Code(err) == codes.Canceled {
        // Create new context and retry if appropriate
        ctx2 := context.Background()
        resp, err = client.SomeRPC(ctx2, req)
    }
}
  2. 85% 成功率 Handle cancellation gracefully by checking context errors. 
    select {
case <-ctx.Done():
    return nil, ctx.Err()
default:
}
resp, err := client.SomeRPC(ctx, req)

无效尝试

常见但无效的做法:

  1. Ignore the cancellation and retry with the same context. 100% 失败

    The cancelled context cannot be reused; a new context is needed.

  2. Remove context cancellation logic entirely. 90% 失败

    This can lead to resource leaks and unresponsive applications.
