Google 协议缓冲区错误:“在序列化协议缓冲区时遇到包含无效 UTF-8 数据的字符串" [英] Google Protocol Buffer error: "Encountered string containing invalid UTF-8 data while serializing protocol buffer"

问题描述

我正在使用以下代码

int lenSend = odl->ByteSize();
char* buf = (char *)malloc(lenSend);
odl->SerializeToArray(buf, lenSend);

我收到此错误，但我不明白为什么会收到此错误(是的，我收到了 3 次):

I get this error and I can't understand why I get it (yes I get it three times):

libprotobuf ERROR google/protobuf/wire_format.cc:1059] 在序列化协议缓冲区时遇到包含无效 UTF-8 数据的字符串.字符串必须仅包含 UTF-8；对原始字节使用 'bytes' 类型.

谢谢.

推荐答案

您可以按照消息中的建议去除警告！

You can get rid of the warning by following the advice in the message!

您必须在 odl(在您的 .proto 文件中)的定义中有一个或多个字段，这些字段被定义为 string 但您将非 UTF-8 个字符.文档声明您不应该这样做.如果您将这些更改为 bytes，警告应该会消失.

You must have a field or fields in the definition of odl (in your .proto file) which are defined as string but into which you are putting non-UTF-8 characters. The docs state that you shouldn't do this. If you change these to bytes, the warnings should disappear.
