cdjingit edited a comment on issue #685: Thrift protocol中序列化的请求时，writeStructBegin 和 writeFieldBegin中的服务名和请求的名是固定的。无法定制 URL: https://github.com/apache/incubator-brpc/issues/685#issuecomment-472372750 因为有些服务server端的实现不是基于brpc的。比如，我们现在开发brpc支持cassandra thrift， 就有很多不同的方法和请求名称。 这里似乎应该直接调用req->raw_instance()->Write(oport) 。直接写入整个请求的struct，就可以。比如 /example/thrift_extension_c++/gen-cpp的例子 ``` 179 void EchoServiceClient::send_Echo(const EchoRequest& request) 180 { 181 int32_t cseqid = 0; 182 oprot_->writeMessageBegin("Echo", ::apache::thrift::protocol::T_CALL, cseqid); 183 184 EchoService_Echo_pargs args; 185 args.request = &request; 186 args.write(oprot_); // args作为raw_instance()传入 直接调用thrift生成的代码写入就可以 187 188 oprot_->writeMessageEnd(); 189 oprot_->getTransport()->writeEnd(); 190 oprot_->getTransport()->flush(); 191 } ``` @kenshinxf
