JSON样例 - 摘要: 本文讲的是JSON样例,#include#include #include "json.h"using namespace std;using namespace Json;void readJson() { std::string strValue = "{/"

#include
#include
#include "json.h"
using namespace std;
using namespace Json;
void readJson()
{
std::string strValue = "{/"name/":/"json/",/"array/":[{/"cpp/":/"jsoncpp/"},{/"java/":/"jsoninjava/"},{/"php/":/"support/"}]}";
Json::Reader reader;
Json::Value value;
if (reader.parse(strValue, value))
{
std::string out = value["name"].asString();
std::cout << out << std::endl;
const Json::Value arrayObj = value["array"];
for (unsigned int i = 0; i < arrayObj.size(); i++)
{
if (!arrayObj[i].isMember("cpp"))
continue;
out = arrayObj[i]["cpp"].asString();
std::cout << out;
if (i != (arrayObj.size() - 1))
std::cout << std::endl;
}
}
}
void writeJson()
{
Json::Value root;
Json::Value arrayObj;
Json::Value item;
item["cpp"] = "jsoncpp";
item["java"] = "jsoninjava";
item["php"] = "support";
arrayObj.append(item);
root["name"] = "json";
root["array"] = arrayObj;
root.toStyledString();
std::string out = root.toStyledString();
std::cout << out << std::endl;
}
int main() {
readJson();
cout << "---------------------------------------------" << endl;
writeJson();
return 0;
}
