分割字符串
//字符串分割函数 std::vector<std::string> split(std::string str, std::string pattern) { std::string::size_type pos; std::vector<std::string> result; str += pattern;//扩展字符串以方便操作 int size = str.size(); for (int i = 0; i < size; i++) { pos = str.find(pattern, i); if (pos < size) { std::string s = str.substr(i, pos - i); result.push_back(s); i = pos + pattern.size() - 1; } } return result; }
