static std::vector<uint8_t> nlohmann::basic_json::to_cbor | ( | const basic_json & | j | ) |
| inline static
  Serializes a given JSON value j to a byte vector using the CBOR (Concise Binary Object Representation) serialization format. CBOR is a binary serialization format which aims to be more compact than JSON itself, yet more efficient to parse. Parameters
  [in] | j | JSON value to serialize
  Returns MessagePack serialization as byte vector Complexity Linear in the size of the JSON value j. Example The example shows the serialization of a JSON value to a byte vector in CBOR format. 1 #include <json.hpp> 2 3 using json = nlohmann::json; 4 5 int main() 6 { 7 // create a JSON value 8 json j = R"({"compact": true, "schema": 0})"_json; 9 10 // serialize it to CBOR 11 std::vector<uint8_t> v = json::to_cbor(j); 12 13 // print the vector content 14 for (auto& byte : v) 15 { 16 std::cout << "0x" << std::hex << std::setw(2) << std::setfill('0') << (int)byte << " "; 17 } 18 std::cout << std::endl; 19 } nlohmann::json basic_json<> json default JSON class Definition: json.hpp:12151 nlohmann::basic_json::to_cbor static std::vector< uint8_t > to_cbor(const basic_json &j) create a MessagePack serialization of a given JSON value Definition: json.hpp:7660 Output (play with this example online):

  The example code above can be translated with
      g++ -std=c++11 -Isrc doc/examples/to_cbor.cpp -o to_cbor
