解析json文件

1.这里只做简单的例子例如json文件内容为

{  "ImagePath": "C:\\Users\\8.mdf",  "DataType": 1,  "IsSelectAll": 0,  "Apps": [    "短信"  ],  "InstallAppInfo": [    {      "Name": "日历",      "FirstInstallTime": "2014-11-28T10:12:52",         },    {      "Name": "360云盘",      "FirstInstallTime": "2017-03-01T16:36:13",      },  ]}

2.定义结构体

struct Test{string m_strPath;int m_iDataType;BOOL m_bSelectedAll;map<CString,bool> m_mapSelectedApps;vector<DeviceAppInfo> m_vecAppDetails;PHLiveParam(){m_iDataType = 0;m_bSelectedAll = TRUE;m_mapSelectedApps.clear();}};

3.解析

BOOL AnalysisPHLiveParam(const CString & strPath,  Test&  ){try{CFile file;if(!file.Open(strPath,CFile::modeRead,NULL)){CString strDetailMsg = L"Can not analysis this pram from json file:";return FALSE;}int nSize = file.GetLength();char *pBuf = new char[nSize + 1];ZeroMemory(pBuf,nSize + 1);file.Read(pBuf,nSize);file.Close();pBuf[nSize] = 0;string strData=pBuf;Json::Reader reader;Json::Value root;if(!reader.parse(strData, root, false)){CString strDetailMsg = L"Can not analysis json file(Wrong json format ):";return FALSE;}test.m_strPath=root["ImagePath"].asString();test..m_iDataType=root["DataType"].asInt();test.m_bSelectedAll = root["IsSelectAll"].asInt();int n=root["Apps"].size();string strTmp;for (int i=0;i<n;i++){strTmp=root["Apps"][i].asString();test.m_mapSelectedApps[strTmp]=true;}n=root["InstallAppInfo"].size();for (int i=0;i<n;i++){DeviceAppInfo AppDetailstemp;AppDetailstemp.m_strAppName =root["InstallAppInfo"][i]["Name"].asString();AppDetailstemp.m_strAppInstallTime =root["InstallAppInfo"][i]["FirstInstallTime"].asString();m_vecAppDetails.push_back(AppDetailstemp);}return TRUE;}catch (std::exception & e){return FALSE;}catch (CException* e){return FALSE;}}

补充：如果文件格式为 json文件嵌套

例如

{"RegisterSource":{"RegisterBody":"深圳市腾讯计算机系统有限公司"},"bizEntryInfo":[{"title":"王者荣耀","username":"gh_7273a02c7e7e","icon_url":"http://mmbiz.qpic.cn/mmbiz_png/LvM7ibdRGl1tjnzCO6jHT4nZYVI8GV0Hic5c4UxfewBOkHjvK36rrkHpYicEBPaYELHbELcosFHM7jT9ic5cM2MWOw/0?wx_fmt=png"}]}

BOOL AnalysisExternalInfo(const CString &strContent,map<CString,CString> &mapstrInfo){try{Json::Reader reader,reader2;Json::Value root,root2;if(!reader.parse(ph_convertToUTF8(strContent).c_str(), root, false)){/*CString strDetailMsg = L"Can not analysis json file(Wrong json format ):";strDetailMsg += strPath;*///CPHLogUtil::InsertDebugLog("AnalysisPHLiveParam Fail",ph_convertToUTF8(strDetailMsg,CP_ACP1));return FALSE;}root2=root["RegisterSource"];CString strTmp=ph_convertFromUTF8(root2["RegisterBody"].asString()).c_str();mapstrInfo.insert(make_pair("RegisterBody",strTmp));root2=root["BindWxaInfo"];int n=root2["bizEntryInfo"].size();for (int i=0;i<n;i++){strTmp=ph_convertFromUTF8(root2["bizEntryInfo"][i]["title"].asString()).c_str();CString strTitle;strTitle.Format(L"title%d",i);mapstrInfo.insert(make_pair(strTitle,strTmp));strTmp=ph_convertFromUTF8(root2["bizEntryInfo"][i]["username"].asString()).c_str();mapstrInfo.insert(make_pair("Appusername",strTmp));}return TRUE;}catch (std::exception & e){//CPHLogUtil::InsertDebugLog("AnalysisPHLiveParam fail",ph_StdExceptionLog(e,""));return FALSE;}catch (CException* e){//CPHLogUtil::InsertDebugLog("AnalysisPHLiveParam fail",ph_ExceptionLog(e));return FALSE;}}
