看最简单的:

 

#include <iostream>
#include <stdio.h>
#include<unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include<sstream>

// 请自己下载开源的rapidjson
#include "rapidjson/prettywriter.h"
#include "rapidjson/rapidjson.h"
#include "rapidjson/document.h"
#include "rapidjson/stringbuffer.h"
#include "rapidjson/writer.h"
#include "rapidjson/memorystream.h"

using namespace std;
using rapidjson::Document;
using rapidjson::StringBuffer;
using rapidjson::Writer;
using namespace rapidjson;

void test()
{
	Document document;
	document.SetObject();
	Document::AllocatorType& allocator = document.GetAllocator();
	Value object(rapidjson::kObjectType);
	
	document.AddMember("age", 29, allocator);
	document.AddMember("name", "taoge", allocator);

	StringBuffer buffer;
	Writer<StringBuffer> writer(buffer);
	document.Accept(writer);
	string str = buffer.GetString();
	
	cout << str << endl;
}

int main(int argc, char *argv[])
{
	test();
	return 0;
}

       结果:{"age":29,"name":"taoge"}

 

 

       再看数组:

 

#include <iostream>
#include <stdio.h>
#include<unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include<sstream>

// 请自己下载开源的rapidjson
#include "rapidjson/prettywriter.h"
#include "rapidjson/rapidjson.h"
#include "rapidjson/document.h"
#include "rapidjson/stringbuffer.h"
#include "rapidjson/writer.h"
#include "rapidjson/memorystream.h"

using namespace std;
using rapidjson::Document;
using rapidjson::StringBuffer;
using rapidjson::Writer;
using namespace rapidjson;

void test()
{
	Document document;
	document.SetObject();
	Document::AllocatorType& allocator = document.GetAllocator();
	Value array(rapidjson::kArrayType);
	Value object(rapidjson::kObjectType);
	
	object.AddMember("age", 30, allocator);
	object.AddMember("name", "taoge", allocator);
	array.PushBack(object, allocator);

	document.AddMember("json", array, allocator);
	
	StringBuffer buffer;
	Writer<StringBuffer> writer(buffer);
	document.Accept(writer);
	string str = buffer.GetString();
	
	cout << str << endl;
}

int main(int argc, char *argv[])
{
	test();
	return 0;
}

     结果:{"json":[{"age":30,"name":"taoge"}]}

 

 

     再来看一个:

 

#include <iostream>
#include <stdio.h>
#include<unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include<sstream>

// 请自己下载开源的rapidjson
#include "rapidjson/prettywriter.h"
#include "rapidjson/rapidjson.h"
#include "rapidjson/document.h"
#include "rapidjson/stringbuffer.h"
#include "rapidjson/writer.h"
#include "rapidjson/memorystream.h"

using namespace std;
using rapidjson::Document;
using rapidjson::StringBuffer;
using rapidjson::Writer;
using namespace rapidjson;

void test()
{
	Document document;
	document.SetObject();
	Document::AllocatorType& allocator = document.GetAllocator();
	Value array(rapidjson::kArrayType);
	Value object(rapidjson::kObjectType);
	
	object.AddMember("age", 30, allocator);
	object.AddMember("name", "taoge", allocator);
	array.PushBack(object, allocator);

	document.AddMember("oh1", array, allocator);
	document.AddMember("oh2", "hehe", allocator);
	
	StringBuffer buffer;
	Writer<StringBuffer> writer(buffer);
	document.Accept(writer);
	string str = buffer.GetString();
	
	cout << str << endl;
}

int main(int argc, char *argv[])
{
	test();
	return 0;
}

       结果:{"oh1":[{"age":30,"name":"taoge"}],"oh2":"hehe"}
