根因分析

客户端和服务器使用的protobuf定义不同步（例如不同的字段编号或类型），导致编组/解组失败。

English

The protobuf definition used by client and server are out of sync (e.g., different field numbers or types), causing marshaling/unmarshaling failures.

generic

解决方案

  1. 95% 成功率 Regenerate protobuf stubs from the same .proto file for both client and server. 
    protoc --go_out=. --go-grpc_out=. *.proto
# ensure same .proto version is used everywhere
  2. 90% 成功率 Use buf tool to enforce proto compatibility checks. 
    buf breaking --against '.git#branch=main'

无效尝试

常见但无效的做法:

  1. Clearing the client cache and retrying. 95% 失败

    The proto definitions are still mismatched; cache is irrelevant.

  2. Manually editing the generated .pb.go files. 90% 失败

    Files are auto-generated; manual edits break regeneration.
