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"}
