protobuf封包转为json格式作为HttpBody发送后返回错误解析base64string失败

JoinBuilder builder = JoinReq.newBuilder();

builder.setChannelId(11142121);

JoinReq JoinBody = builder.build();



ByteString buf =  JoinBody.toByteString();

PackageBuilder packbuilder = Package.newBuilder();

packbuilder.setBody(buf);

Package upackage = packbuilder.build();



LogicBuilder logicbuilder = LogicReq.newBuilder();

logicbuilder.setPackage(upackage);

LogicReq logicLayerReq = logicbuilder.build();

String body = JsonFormat.printToString(logicLayerReq);

Fail to parse http body as UU.LogicLayerReq, Fail to decode base64 string=￩ﾇﾨ
