1、读取=号的配置文件(或者:)的配置。
#include <iostream> #include <fstream> #include <sstream> #include <map> #include <string> std::map<std::string, std::string> read_config(const std::string &filename) { std::map<std::string, std::string> config; std::ifstream file(filename); std::string line; if (!file.is_open()) { throw std::runtime_error("Unable to open config file"); } while (getline(file, line)) { std::istringstream is_line(line); std::string key; if (getline(is_line, key, '=')) { std::string value; if (getline(is_line, value)) { config[key] = value; } } } file.close(); return config; } int main() { try { auto config = read_config("config.ini"); for (const auto &pair : config) { std::cout << pair.first << " = " << pair.second << std::endl; } } catch (const std::exception &e) { std::cerr << "Error: " << e.what() << std::endl; } return 0; }
