使用zlib库进行gzip压缩的示例代码：
#include <iostream>#include <zlib.h>int main() { const char *input_data = "Hello, World!"; uLong input_size = strlen(input_data) + 1; uLong output_size = compressBound(input_size); Bytef* output_data = new Bytef[output_size]; compress(output_data, &output_size, (Bytef*)input_data, input_size); std::cout << "Compressed data: "; for (uLong i = 0; i < output_size; i++) { std::cout << output_data[i]; } delete[] output_data; return 0;}#include <iostream>#include <boost/iostreams/filtering_stream.hpp>#include <boost/iostreams/filter/gzip.hpp>#include <boost/iostreams/copy.hpp>int main() { std::string input_data = "Hello, World!"; std::stringstream compressed_data; boost::iostreams::filtering_ostream out; out.push(boost::iostreams::gzip_compressor(boost::iostreams::gzip_params(boost::iostreams::gzip::best_compression))); out.push(compressed_data); out << input_data; out.pop(); std::cout << "Compressed data: " << compressed_data.str() << std::endl; return 0;}这两个示例代码分别使用zlib库和Boost库实现了gzip压缩。可以根据实际需求选择合适的库进行使用。
