C++中buffer的序列化与反序列化方法是什么

在C++中，可以使用std::ofstream和std::ifstream来进行buffer的序列化和反序列化。

序列化：

#include <iostream> #include <fstream> #include <vector>  void serializeBuffer(const std::vector<char>& buffer, const std::string& filename) {     std::ofstream out(filename, std::ios::binary);     if(out.is_open()) {         out.write(buffer.data(), buffer.size());         out.close();     } else {         std::cout << "Failed to open file for writing." << std::endl;     } }  int main() {     std::vector<char> buffer = {'a', 'b', 'c', 'd', 'e'};     serializeBuffer(buffer, "serialized_buffer.bin");      return 0; } 

反序列化：

#include <iostream> #include <fstream> #include <vector>  std::vector<char> deserializeBuffer(const std::string& filename) {     std::ifstream in(filename, std::ios::binary);     std::vector<char> buffer;      if(in.is_open()) {         in.seekg(0, std::ios::end);         buffer.resize(in.tellg());         in.seekg(0, std::ios::beg);          in.read(buffer.data(), buffer.size());         in.close();     } else {         std::cout << "Failed to open file for reading." << std::endl;     }      return buffer; }  int main() {     std::string filename = "serialized_buffer.bin";     std::vector<char> deserializedBuffer = deserializeBuffer(filename);      for(char c : deserializedBuffer) {         std::cout << c << " ";     }     std::cout << std::endl;      return 0; } 

这样就可以将buffer序列化到文件中，并从文件中反序列化出来。
