根因分析

服务器拒绝请求，因为资源（例如数据库记录）处于不允许操作的状态，例如尝试删除已删除的项目。

English

The server rejected the request because the resource (e.g., database record) is in a state that doesn't allow the operation, such as trying to delete an already deleted item.

解决方案

  1. 90% 成功率 Check resource state before the RPC and handle accordingly. 
    state, _ := client.GetState(ctx, &pb.GetStateRequest{Id: id})
if state.Status != "active" { return errors.New("cannot perform operation on inactive resource") }
  2. 85% 成功率 Use a transactional pattern to ensure state validity. 
    // Implement optimistic locking with version field
req.Version = currentVersion
resp, err := client.UpdateResource(ctx, req)
if status.Code(err) == codes.FailedPrecondition { // retry with fresh version }

无效尝试

常见但无效的做法:

  1. Retrying the same request immediately. 90% 失败

    Resource state hasn't changed; same error.

  2. Ignoring the error and proceeding with other operations. 80% 失败

    May cause data inconsistency; need to handle the state.
