具有HTTP请求的二进制有效载荷，或在HTTP响应中。只需将协议缓冲区的字节直接写入请求/响应，并确保将内容类型设置为application / octet-stream。客户端和服务器应该能够轻松地处理休息。我不认为你需要任何更加特别的任何一端。

You can certainly send even a binary payload with an HTTP request, or in an HTTP response. Just write the bytes of the protocol buffer directly into the request/response, and make sure to set the content type to "application/octet-stream". The client, and server, should be able to take care of the rest easily. I don't think you need anything more special than that on either end.
