rpc调用的时候，发现字符串长度最长是uint16_t，大概是64k，能否允许传递更长的字符串，比如10M以内，因为代码有点看不懂，我改了几次无法成功

我用的是2010的buttonrpc:

修改了一下，好像是可以了：

`
template
inline void Serializer::output_type(T& t)
{
int len = sizeof(T);
char* d = new char[len];
if (!m_iodevice.is_eof()){
memcpy(d, m_iodevice.current(), len);
m_iodevice.offset(len);
byte_orser(d, len);
t = reinterpret_cast<T>(&d[0]);
}
delete [] d;
}

template<>
inline void Serializer::output_type(std::string& in)
{
int marklen = sizeof(uint32_t);
char* d = new char[marklen];
memcpy(d, m_iodevice.current(), marklen);
byte_orser(d, marklen);
int len = reinterpret_cast<uint32_t>(&d[0]);
m_iodevice.offset(marklen);
delete [] d;
if (len == 0) return;
in.insert(in.begin(), m_iodevice.current(), m_iodevice.current() + len);
m_iodevice.offset(len);
}

template
inline void Serializer::input_type(T t)
{
int len = sizeof(T);
char* d = new char[len];
const char* p = reinterpret_cast<const char*>(&t);
memcpy(d, p, len);
byte_orser(d, len);
m_iodevice.input(d, len);
delete [] d;
}

template<>
inline void Serializer::input_type(std::string in)
{
// 先存入字符串长度
uint32_t len = in.size();
char* p = reinterpret_cast< char*>(&len);
byte_orser(p, sizeof(uint32_t));
m_iodevice.input(p, sizeof(uint32_t));

// 存入字符串
if (len == 0) return;
char* d = new char[len];
memcpy(d, in.c_str(), len);
m_iodevice.input(d, len);
delete [] d;

}

template<>
inline void Serializer::input_type(const char* in)
{
input_typestd::string(std::string(in));
}`
