uint8_t数组转string

可以使用以下代码将uint8_t数组转换为string：

#include <iostream>
#include <sstream>

std::string uint8ToString(uint8_t* data, size_t len) {
    std::stringstream ss;
    for(size_t i = 0; i < len; i++) {
        ss << std::hex << static_cast<int>(data[i]);
    }
    return ss.str();
}

int main() {
    uint8_t data[] = {0x68, 0x65, 0x6c, 0x6c, 0x6f};
    size_t length = sizeof(data) / sizeof(uint8_t);

    std::string str = uint8ToString(data, length);
    std::cout << str << std::endl;

    return 0;
}

输出结果为：68656c6c6f
