C++字节流转字符串

直接上代码

所需头文件 : <string>, <stdio.h>, <stdint.h>

std::string ByteStream2String(const uint8_t *pByteStream, size_t iStreamLen)
{
  std::string sRet = "";
  char curr_byte[3];

  for (size_t idx = 0; idx < iStreamLen; ++idx)
  {
    memset(curr_byte, 0, 3);
    sprintf_s(curr_byte, "%02hhX", pByteStream[idx]);

    sRet += curr_byte;
    sRet += " ";
  }

  return sRet;
}

测试如下

运行结果如下

 

以上, 如有错误疏漏, 欢迎指正
