CString strTemp; //CString ->string; string stringMsg = (LPCSTR)(CStringA)strTemp; //string -> CString strTemp= stringMsg.c_str();
原本是想接入jsonCPP,不过多线程调试一直不兼容,修改 MDd,MTd还是没有什么用;后来想了想,干脆自己写个;
思路:用字典解决;
void CDlg::SetMap(CMap<CString, LPCTSTR, CString, LPCTSTR> &mapContent,CString msgJson) { CStringArray strArray; CString strTemp = msgJson; string stringMsg = (LPCSTR)(CStringA)strTemp; strTemp.Remove('"'); strTemp.Remove('{'); strTemp.Remove('}'); int strTempLength = strTemp.GetLength(); int index = 0; while(true){ index = strTemp.Find(','); if (-1 == index) { strArray.Add(strTemp); break; } strArray.Add(strTemp.Left(index)); strTemp = strTemp.Right(strTemp.GetLength() - index - 1); } int length = strArray.GetSize(); CString strMap; int subIndex = 0; CString strKey(""); CString strValue(""); for (int i = 0; i < length; i++) { strMap = strArray.GetAt(i); subIndex = strMap.Find(':'); strKey = strMap.Left(subIndex); strValue = strMap.Right(strMap.GetLength() - subIndex - 1); mapContent.SetAt(strKey, strValue); } }
void CDlg::MsgJson(CString msgJson) { CMap<CString, LPCTSTR, CString, LPCTSTR> my_Map; SetMap(my_Map, msgJson); CString pLook; my_Map.Lookup(L"type", pLook); };
这样就可以解析简单的json.如果有多层,那么就首先通过寻找 {},进行数据分割,原理大同小异;
