本系列文章以例子的方式进行呈现。

#include <iostream>
#include "rapidjson/rapidjson.h"
#include "rapidjson/document.h"
#include "rapidjson/stringbuffer.h"
#include "rapidjson/writer.h"
#include "rapidjson/filereadstream.h"
#include "cstdio"

using namespace std;
using namespace rapidjson;

int main() {
  const char json[] = "[1, 2, 3]";
  StringStream s(json);
  Document document;
  document.ParseStream(s);

  for (int i = 0; i < 3; i++)
    std::cout << document[i].GetInt() << std::endl;

  StringBuffer SB;
  Writer<StringBuffer> writer(SB);
  document.Accept(writer);
  std::cout << SB.GetString() << std::endl;

  FILE* fp = fopen("test.json", "rb");

  char readBuffer[65535];
  FileReadStream is(fp, readBuffer, sizeof(readBuffer));

  document.ParseStream(is);
  fclose(fp);
  for (Value::ConstMemberIterator it = document.MemberBegin();
        it != document.MemberEnd(); it++)
        std::cout << (it->name).GetString() << std::endl;
}
