如何将模板可变参数存储到std::ofstream中？

#include <iostream>
#include <fstream>
#include <sstream>

template<typename... Args>
void storeParamsToFile(const std::string& filename, Args&&... args) {
    std::ofstream file(filename);
    if (file.is_open()) {
        // 使用std::ostringstream将可变参数转换为字符串
        std::ostringstream oss;
        (oss << ... << args);
        
        // 将字符串写入文件
        file << oss.str();
        
        file.close();
    } else {
        std::cout << "无法打开文件：" << filename << std::endl;
    }
}

int main() {
    int num1 = 10;
    double num2 = 3.14;
    std::string str = "Hello, World!";
    
    storeParamsToFile("output.txt", num1, num2, str);
    
    return 0;
}
