protocol-buffers - Google Protocol Buffer 错误 : "Encountered string containing invalid UTF-8 data while serializing protocol buffer"

Question

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):

libprotobuf ERROR google/protobuf/wire_format.cc:1059] Encountered string containing invalid UTF-8 data while serializing protocol buffer. Strings must contain only UTF-8; use the 'bytes' type for raw bytes.
libprotobuf ERROR google/protobuf/wire_format.cc:1059] Encountered string containing invalid UTF-8 data while serializing protocol buffer. Strings must contain only UTF-8; use the 'bytes' type for raw bytes.
libprotobuf ERROR google/protobuf/wire_format.cc:1059] Encountered string containing invalid UTF-8 data while serializing protocol buffer. Strings must contain only UTF-8; use the 'bytes' type for raw bytes.

谢谢。

您可以按照消息中的建议去除警告!

您必须在 odl 的定义中有一个或多个字段(在您的 .proto 文件中)定义为 string但您将非 UTF-8 字符放入其中。 The docs state that you shouldn't do this .如果您将这些更改为 bytes ，警告应该消失。
