cocos2dx 获取网络时间

一般消除游戏都有体力回复的功能，很多消除游戏都是取的本地时间，这样的坏处就是用户修改了手机的时间就可以回复满体力。

实现代码如下：

思路就是使用百度的时间api获取到网页，然后在网页中抓取到时间戳查看网页的源代码就可以发现源代码中有一个

window.baidu_time(1447841230045); 这一串数字就是时间戳这里我们只要精确到秒级所以取前面10位就可以。

抓取时间戳就是通过“window.baidu_time(”关键字把网页源代码字符串切割成两半然后取后面一半的前面10个字符，再把字符串转换为时间就可以了。

切割字符串函数

//切割字符串static void splitString(std::vector<std::string> &contentVector,std::string content, std::string pattern){std::string::size_type pos;//std::vector<std::string> result;  content += pattern;//扩展字符串以方便操作  int size = content.size();for (int i = 0; i<size; i++){pos = content.find(pattern, i);if (pos<size){std::string s = content.substr(i, pos - i);// result.push_back(s);  contentVector.push_back(s);i = pos + pattern.size() - 1;}}}
