APIs

Automatically Compress Served Content

Configure server::ConnectionHandler in AppComponent.hpp.

#include "oatpp-zlib/EncoderProvider.hpp"

...


OATPP_CREATE_COMPONENT(std::shared_ptr<oatpp::network::server::ConnectionHandler>, serverConnectionHandler)([] {

  OATPP_COMPONENT(std::shared_ptr<oatpp::web::server::HttpRouter>, router); // get Router component

  /* Create HttpProcessor::Components */
  auto components = std::make_shared<oatpp::web::server::HttpProcessor::Components>(router);

  /* Add content encoders */
  auto encoders = std::make_shared<oatpp::web::protocol::http::encoding::ProviderCollection>();

  encoders->add(std::make_shared<oatpp::zlib::DeflateEncoderProvider>());
  encoders->add(std::make_shared<oatpp::zlib::GzipEncoderProvider>());

  /* Set content encoders */
  components->contentEncodingProviders = encoders;

  /* return HttpConnectionHandler */
  return std::make_shared<oatpp::web::server::HttpConnectionHandler>(components);
  
}());

...

Now served content will be automatically compressed and streamed to the client if the client sets Accept-Encoding header appropriately.

Automatically Decompress Uploaded Content

Configure server::ConnectionHandler in AppComponent.hpp.

#include "oatpp-zlib/EncoderProvider.hpp"
#include "oatpp/web/protocol/http/incoming/SimpleBodyDecoder.hpp"

...

OATPP_CREATE_COMPONENT(std::shared_ptr<oatpp::network::server::ConnectionHandler>, serverConnectionHandler)([] {

  OATPP_COMPONENT(std::shared_ptr<oatpp::web::server::HttpRouter>, router); // get Router component

  /* Create HttpProcessor::Components */
  auto components = std::make_shared<oatpp::web::server::HttpProcessor::Components>(router);

  /* Add content decoders */
  auto decoders = std::make_shared<oatpp::web::protocol::http::encoding::ProviderCollection>();

  decoders->add(std::make_shared<oatpp::zlib::DeflateDecoderProvider>());
  decoders->add(std::make_shared<oatpp::zlib::GzipDecoderProvider>());

  /* Set Body Decoder */
  components->bodyDecoder = std::make_shared<oatpp::web::protocol::http::incoming::SimpleBodyDecoder>(decoders);

  /* return HttpConnectionHandler */
  return std::make_shared<oatpp::web::server::HttpConnectionHandler>(components);
  
}());

...

Now uploaded content will be automatically decompressed if the client sets Content-Encoding header properly.
