导读：头文件 #include " json/document.h " #include json/prettywriter.h json/stringbuffer.h " 这是生成数组的 void test(){ string info = {"id":"2222211","cards":[0,1,2,3,4,5,6,7,8,9],"jiaoDiZhu":""} " ; rapidjson::Document doc; doc.Parse

头文件 #include "json/document.h" #include json/prettywriter.hjson/stringbuffer.h"
这是生成数组的 void test() { string info = {"id":"2222211","cards":[0,1,2,3,4,5,6,7,8,9],"jiaoDiZhu":""}"; rapidjson::Document doc; doc.Parse<0>(info.c_str()); rapidjson::Value &dataArray = doc[cards"]; if (dataArray.IsArray()) { for (rapidjson::SizeType i = 0; i < dataArray.Size(); i++) { const rapidjson::Value& object = dataArray[i]; printf(%dn",object.GetInt()); } } }
//read json
string updateInfo = {"UpdateInfo":[{"url":"aaaa.ipa","platform":"ios"}]}";
rapidjson::Document doc;
doc.Parse<0>(updateInfo.c_str());
rapidjson::Value &dataArray = doc[UpdateInfofor (int i = object = dataArray[i];
string url = object[url"].GetString();
string platform = platform"].GetString();
}
}
write json
rapidjson::Document document;
document.SetObject();
rapidjson::Document::AllocatorType& allocator = document.GetAllocator();
rapidjson::Value array(rapidjson::kArrayType);
0; i < 10; i++)
{
rapidjson::Value object(rapidjson::kObjectType);
object.AddMember(id1,allocator);
nametest",0); line-height:1.5!important">version1.01,0); line-height:1.5!important">viptrue,allocator);
object.SetInt(i);
array.PushBack(object,allocator);
}
document.AddMember(titlePLAYER INFOplayers writer(buffer);
document.Accept(writer);
auto out = buffer.GetString();
log(out: %sout);
}
下面是单个的 void readTest()
{
char json[] = {"carriorName":"日本电信","deviceName":"iPhone5,2","osName":"android","osVersion":"8.1","appId":"com.mmcshadow.doudizhu","versionName":"1.0","versionCode":"1.0","deviceId":"22222111"}";
rapidjson::Document d;
d.Parse<0>(json);
printf(%sncarriorName"].GetString());
printf(
void writeTest()
{
rapidjson::Document document;
rapidjson::Document::AllocatorType& allocator = document.GetAllocator();
rapidjson::Value root(rapidjson::kObjectType);
root.AddMember(哥伦布啊gold1234,allocator);
rapidjson::StringBuffer buffer;
rapidjson::Writer<rapidjson::StringBuffer> writer(buffer);
root.Accept(writer);
std::string reststring = buffer.GetString();
std::cout << reststring << std::endl;
}
