根因分析

客户端或服务端在流关闭后（已调用 CloseSend、服务端已返回，或上下文取消）调用了 Send。对已终止流的写入会被拒绝。

English

The client or server called Send on a stream after it was closed (CloseSend called, server returned, or context canceled). Writes to a terminal stream are rejected.

解决方案

  1. 80% 成功率 
    stream, err := client.Upload(ctx)
if err != nil { return err }
for _, m := range msgs {
    if err := stream.Send(m); err != nil {
        stream, err = client.Upload(ctx) // reopen
        if err != nil { return err }
    }
}
  2. 85% 成功率 
    defer stream.CloseSend()
// ensure all Send calls complete before CloseSend runs

无效尝试

常见但无效的做法:

  1. 90% 失败

    A closed stream cannot be reopened; the same stream handle remains terminal.

  2. 85% 失败

    Closure is a state, not a timing race; sleeping does not reopen the stream.
