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：
