如何将参数包扩展为vector<any>

#include <iostream>
#include <vector>
#include <any>

// 递归终止条件：参数包为空
void expandParams(std::vector<std::any>& result) {}

// 递归展开参数包
template<typename T, typename... Args>
void expandParams(std::vector<std::any>& result, T&& arg, Args&&... args) {
    result.emplace_back(std::forward<T>(arg));  // 将参数转换为std::any并添加到vector中
    expandParams(result, std::forward<Args>(args)...);  // 递归处理剩余的参数
}

int main() {
    std::vector<std::any> params;
    expandParams(params, 1, "hello", 3.14, true);

    // 输出参数包中的内容
    for (const auto& param : params) {
        if (param.type() == typeid(int)) {
            std::cout << "int: " << std::any_cast<int>(param) << std::endl;
        } else if (param.type() == typeid(const char*)) {
            std::cout << "const char*: " << std::any_cast<const char*>(param) << std::endl;
        } else if (param.type() == typeid(double)) {
            std::cout << "double: " << std::any_cast<double>(param) << std::endl;
        } else if (param.type() == typeid(bool)) {
            std::cout << "bool: " << std::any_cast<bool>(param) << std::endl;
        }
    }

    return 0;
