c++，将std::string转换为uint8_t

#include <iostream>
#include <vector>
#include <string>

std::vector<uint8_t> stringToUint8(const std::string& str) {
    std::vector<uint8_t> result;
    result.assign(str.begin(), str.end());
    return result;
}

int main() {
    std::string str = "Hello, World!";
    std::vector<uint8_t> uint8Arr = stringToUint8(str);

    // 输出转换后的uint8_t数组
    for (const auto& val : uint8Arr) {
        std::cout << static_cast<int>(val) << " ";
    }
    std::cout << std::endl;

    return 0;
}

#include <iostream>
#include <string>

int main() {
    std::string str = "Hello, World!";
    const uint8_t* uint8Arr = reinterpret_cast<const uint8_t*>(str.c_str());

    // 输出转换后的uint8_t数组
    for (size_t i = 0; i < str.length(); i++) {
        std::cout << static_cast<int>(uint8Arr[i]) << " ";
    }
    std::cout << std::endl;

    return 0;
}
