根因分析

客户端尝试使用非流式RPC存根调用服务器流式或双向流式方法。

English

The client attempted to call a server-streaming or bidirectional streaming method using a unary RPC stub.

解决方案

  1. 95% 成功率 Use the correct streaming client stub for the method. 
    stream, err := client.StreamData(ctx, &pb.StreamRequest{})
if err != nil { return err }
for {
    resp, err := stream.Recv()
    if err == io.EOF { break }
    if err != nil { return err }
    // process resp
}
  2. 90% 成功率 Regenerate protobuf code to ensure proper client stubs are created. 
    protoc --go_out=. --go-grpc_out=. --go-grpc_opt=require_unimplemented_servers=false myservice.proto

无效尝试

常见但无效的做法:

  1. Use the same stub but with different parameters. 100% 失败

    The stub type is fixed; unary stub cannot handle streaming methods.

  2. Ignore the error and treat the response as a single message. 100% 失败

    The server expects a stream; the client must use the correct streaming API.
