在c++中解析字符串，就像python的解析包

#include <iostream>
#include <string>
#include <sstream>

int main() {
    std::string input = "key1=value1;key2=value2;key3=value3";
    std::stringstream ss(input);
    std::string token;

    while (std::getline(ss, token, ';')) {
        size_t pos = token.find('=');
        std::string key = token.substr(0, pos);
        std::string value = token.substr(pos + 1);
        std::cout << "Key: " << key << ", Value: " << value << std::endl;
    }

    return 0;
}

#include <iostream>
#include <string>
#include <vector>
#include <boost/algorithm/string.hpp>

int main() {
    std::string input = "key1=value1;key2=value2;key3=value3";
    std::vector<std::string> tokens;
    boost::split(tokens, input, boost::is_any_of(";"));

    for (const std::string& token : tokens) {
        std::vector<std::string> keyValue;
        boost::split(keyValue, token, boost::is_any_of("="));
        std::cout << "Key: " << keyValue[0] << ", Value: " << keyValue[1] << std::endl;
    }

    return 0;
}
