rapidjson组装继续简化------人生苦短，我用rapidjson

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：
