代码发生在第257行,因为警告消息说.但我无法解决它,因为我不知道是什么错误..

字符串数据包含通过http的基本身份验证的“用户：密码”字符串.

http.cpp(257)：

// typdef,prepare
using namespace boost::archive::iterators;
stringstream os;
typedef 
    insert_linebreaks<         // insert line breaks every 72 characters
        base64_from_binary<    // convert binary values ot base64 characters
            transform_width<   // retrieve 6 bit integers from a sequence of 8 bit bytes
                const char *,8
