我在Boost Asio 程式中发现错误, 像 Asio 程序( Boost Asio 程序)
if (!error)
{
//do stuff
}
else
{
std::cout << "Error : " << error << std::endl;
//handle error
}
但错误不能为人读( 例如, 连接到没有证书的 SSL 服务器时会发生错误 。 ssl: 335544539) 。 是否有更好的方法显示错误?

如果您可能使用 boost::: system::error_code
, 您可以调用 :
error.message()
以获得更人道的信息。
使用 operator<<
翻译为 :
os << ec.category().name() << : << ec.value()
这里 您可以在eror_code
中查看现有成员的详细概况。
