1、json表如下：
{
"entities": [
{
"entity": {
"TapOpposite": 0,
"Interval": 0.95,
"BallNum": 1
}
},
{
"entity": {
"TapOpposite": 0,
"Interval": 0.91,
"BallNum": 2
}
},
{
"entity": {
"TapOpposite": 0,
"Interval": 0.95,
"BallNum": 3
}
}
]
}
读取函数如下：我们用到的是cocostudio中
rapidjson,包含在cocostudio工程中。所以我们要先引入#include "cocostudio/CocoStudio.h"
void GameWorld::readJson()
{
//json 文档
rapidjson::Document _doc;
bool bRet = false;
ssize_t size = 0;
unsigned char *pBytes = NULL;
do {
pBytes = cocos2d::CCFileUtils::sharedFileUtils()->getFileData("ball.json", "r", &size);
CC_BREAK_IF(pBytes == NULL || strcmp((char*)pBytes, "") == 0);
std::string load_str((const char*)pBytes, size);
CC_SAFE_DELETE_ARRAY(pBytes);
_doc.Parse<0>(load_str.c_str());
CC_BREAK_IF(_doc.HasParseError());
//生成json文档对像
if(!_doc.IsObject())
return;
//是否有此成员
if(!_doc.HasMember("entities"))
return;
// 通过[]取成员值,再根据需要转为array,int,double,string
const rapidjson::Value &pArray = _doc["entities"];
//是否是数组
if(!pArray.IsArray())
return;
for (rapidjson::SizeType i = 0; i < pArray.Size(); i++)
{
const rapidjson::Value &p = pArray[i];
if(p.HasMember("entity"))
{
const rapidjson::Value &valueEnt = p["entity"];
if(valueEnt.HasMember("TapOpposite") && valueEnt.HasMember("Interval") && valueEnt.HasMember("BallNum"))
{
const rapidjson::Value &tapOpposite = valueEnt["TapOpposite"];
int tapOp = tapOpposite.GetInt(); //得到int值
const rapidjson::Value &interval = valueEnt["Interval"];
float inter = interval.GetDouble(); //得到float,double值
const rapidjson::Value &ballNum = valueEnt["BallNum"];
int ball = ballNum.GetInt(); //得到int值
}
}
else
{
return;
}
}
bRet = true;
} while (0);
}
2、json表如下：
[{"name":"zhangsan","age":20,"male":true},{"name":"lisi","age":30,"male":false}]
#include <json/rapidjson.h> #include <json/document.h>
void MyTest::readJson()
{
std::string strContent = FileUtils::getInstance()->getStringFromFile("data.json");
rapidjson::Document oDoc;
oDoc.Parse<0>(strContent.c_str());
if (oDoc.HasParseError())
{
log("Parse Error: %s\n", oDoc.GetParseError());
return false;
}
if (oDoc.IsNull() || !oDoc.IsArray())
{
return false;
}
for (int i = 0; i < oDoc.Size(); i++)
{
if (oDoc[i]["name"].IsNull())
{
return false;
}
log("name=========%s", oDoc[i]["name"].GetString());
if (oDoc[i]["age"].IsNull())
{
return false;
}
log("name=========%d", oDoc[i]["age"].GetInt());
if (oDoc[i]["male"].IsNull())
{
return false;
}
log("male=========%d", oDoc[i]["male"].GetBool());
}
}后续会将lua的读取方式也更新上来
