boost::property_tree::ptree能否处理带有UTF-8 BOM的文件?
#include <boost/filesystem.hpp>
#include <boost/property_tree/ini_parser.hpp>
#include <cstdlib>
#include <iostream>
int main()
{
try
{
boost::filesystem::path path("helper.ini");
boost::property_tree::ptree pt;
boost::property_tree::read_ini(path.string(), pt);
const std::string foo = pt.get<std::string>("foo");
std::cout << foo << '\n';
}
catch (const boost::property_tree::ini_parser_error& e)
{
std::cerr << "An error occurred while reading config file: " << e.what() << '\n';
return EXIT_FAILURE;
}
catch (const boost::property_tree::ptree_bad_data& e)
{
std::cerr << "An error occurred while getting options from config file: " << e.what() << '\n';
return EXIT_FAILURE;
}
catch (const boost::property_tree::ptree_bad_path& e)
{
std::cerr << "An error occurred while getting options from config file: " << e.what() << '\n';
return EXIT_FAILURE;
}
catch (...)
{
std::cerr << "Unknown error \n";
return EXIT_FAILURE;
}
}
helper.ini
foo=str
输出
从配置文件获取选项时出现错误:找不到节点(foo)
我该怎么做?在读取文件之前手动删除BOM吗?
