# rpc error: code = Aborted desc = 在 CloseSend 之后调用了 SendMsg

- **ID:** `go/grpc-aborted-streaming-write`
- **领域:** go
- **类别:** runtime_error
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

客户端流式代码在 stream.CloseSend() 之后或服务端已发送终止状态后调用 stream.Send，违反了客户端流状态机。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| 1.x | active | — | — |

## 解决方案

1. **** (92% 成功率)
   ```
   for _, item := range items {
  if err := stream.Send(item); err != nil {
    return fmt.Errorf("send: %w", err)
  }
}
if err := stream.CloseSend(); err != nil { return err }
resp, err := stream.CloseAndRecv()
   ```
2. **** (85% 成功率)
   ```
   if err := stream.Context().Err(); err != nil {
  return err
}
stream.Send(item)
   ```

## 无效尝试

- **** — Stream is already closed; subsequent sends keep returning Aborted. (90% 失败率)
- **** — Streams are single-use; a new client.Upload(ctx) call is required. (85% 失败率)
