3、对象读取
{list: [{name: 亮度92,props: {BacklightCompensation: 1,Brightness: 92,ColorEnable: 16,Contrast: 91,Gain: 16,Gamma: 62,Hue: 91,Saturation: 255,Sharpness: 62,WhiteBalance: -1},control: {Exposure: -4,Focus: 0,Iris: 100,Pan: 0,Roll: 0,Tilt: 0,Zoom: 100}},{name: 高亮170,props: {BacklightCompensation: 0,Brightness: 170,ColorEnable: 3,Contrast: 128,Gain: 3,Gamma: 188,Hue: 128,Saturation: 128,Sharpness: 188,WhiteBalance: -1},control: {Exposure: -4,Focus: 0,Iris: 100,Pan: 0,Roll: 0,Tilt: 0,Zoom: 100}}]
} 对象的值又是数组的情况下读取方式 CJsonObj ampJson(jsonS.c_str());{int nCount 0;int err;CJsonObj* arry ampJson.getObj(list, err);if (arry arry-isarray()) {nCount arry-get_arry_size();std::string s;std::wstring name;for (int i 0; i arry-get_arry_size(); i) {CJsonObj* pJson arry-get_arry_at(i);pJson-getString(name, s);name to_wchar_t(s);g_SelfCamAmpPropNameVec.push_back(name);}}} 类似的还有 CBinBuf bfJson;if(bfJson.ReadFile(m_file)) {load(bfJson, 0); void load(const char* jstr, int merge) {uint32_t now (uint32_t)time(0);CJsonObj js(jstr);m_tm js.getInt(tm, 0);m_tmReport js.getInt(tmReport, now);int err;CJsonObj* pList js.getObj(list, err);if(pList) {std::vectorCDNINFO v, vOld;if(merge) {for(int i0; im_vCdn.size(); i) vOld.push_back(m_vCdn[i]);}m_vCdn.clear();for(int i0; ipList-get_arry_size(); i) {CDNINFO c;CJsonObj* pItem pList-get_arry_at(i);c.from(pItem);add(c, merge, vOld);}}} 二、写数据 1、简单生成JSON CJsonString bf({);bf.append_item(file, szUtf8);bf.append_item(url, cbitem-url);bf.append_item(wparam,(uint64_t)cbitem-wParam);bf.close(}); 又如
void MakeDefaultJson(CJsonString jsonStr){jsonStr.append_item(is_beauty_on, 1); //美颜全局开关0为关1为开默认为1//滤镜 jsonStr.append_item(filter_level, 0); //0-10 -[0,1] 取值范围 0.0-1.0,0.0为无效果1.0为最大效果默认值1.0jsonStr.append_item(filter_name, origin);//美白jsonStr.append_item(color_level, 2); //0-20 [0,2.0] 取值范围 0.0-2.0,0.0为无效果2.0为最大效果默认值0.2//红润jsonStr.append_item(red_level, 5); //0-20 [0,2.0] 取值范围 0.0-2.0,0.0为无效果2.0为最大效果默认值0.5//磨皮程度jsonStr.append_item(blur_level, 60); //[0,6.0] 磨皮程度取值范围0.0-6.0默认6.0jsonStr.append_item(skin_detect, 0); //肤色检测开关0为关1为开 默认0jsonStr.append_item(nonskin_blur_scale, 0); //0-10 [0,1]肤色检测之后非肤色区域的融合程度取值范围0.0-1.0默认0.0jsonStr.append_item(heavy_blur, 0); //朦胧磨皮开关0为清晰磨皮1为朦胧磨皮jsonStr.append_item(blur_type, 2); //此参数优先级比heavy_blur低在使用时要将heavy_blur设为00 清晰磨皮 1 朦胧磨皮 2精细磨皮jsonStr.append_item(blur_use_mask, 0); //ios端默认为1其他端默认为0。1为开启基于人脸的磨皮mask0为不使用mask正常磨皮。只在blur_type为2时生效。jsonStr.append_item(sharpen, 2); //锐化程度取值范围0.0-1.0默认0.2jsonStr.close();//jsonStr.WriteFile(jsonInfoRes.json);
} 2、对象数组JSON CJsonString jsonStr;jsonStr.begin([);for (auto it : camIDResMap){CJsonString camJson;camJson.begin({);camJson.append_item(id, it.first.c_str());camJson.append_item(res, it.second.c_str());camJson.close(});jsonStr.append_obj(camJson);}jsonStr.close(]);jsonStr.WriteFile(m_camjsonPath); 3、嵌套对象 {list: [{name: 亮度92,props: {BacklightCompensation: 1,Brightness: 92},control: {Exposure: -4,Zoom: 100}},{name: 高亮170,props: {BacklightCompensation: 0,WhiteBalance: -1},control: {Exposure: -4,Zoom: 100}}]
} CJsonString jsonStr;jsonStr.begin([);int nCount 0;for (auto it : selfCamPros_){std::mapstd::string, int ampMap it.second;std::wstring nameW it.first;std::mapstd::string, int ctlMap selfCamControls_[nameW];std::string name to_string(nameW);CJsonString camAllJson;camAllJson.begin({);camAllJson.append_item(name, name.c_str());CJsonString ampJsonObj;ampJsonObj.begin({);auto oneAmpIt ampMap.begin();while (oneAmpIt ! ampMap.end()){ampJsonObj.append_item(oneAmpIt-first.c_str(), oneAmpIt-second);oneAmpIt;}ampJsonObj.close(});camAllJson.append_obj(props, ampJsonObj);CJsonString ctlJsonObj;ctlJsonObj.begin({);auto oneCtlIt ctlMap.begin();while (oneCtlIt ! ctlMap.end()){ctlJsonObj.append_item(oneCtlIt-first.c_str(), oneCtlIt-second);oneCtlIt;}ctlJsonObj.close(});camAllJson.append_obj(control, ctlJsonObj);camAllJson.close(});jsonStr.append_obj(camAllJson);}jsonStr.close(]);CJsonString listObjJsonS;listObjJsonS.begin({);listObjJsonS.append_obj(list, jsonStr);listObjJsonS.close(});listObjJsonS.WriteFile(sysJsonPath); 又如 CJsonString js, list;js.append_item_u32(tm, m_tm);js.append_item_u32(tmReport, m_tmReport);format_json(list);js.append_obj(list, list);js.close(});js.WriteFile(m_file); void format_json(CJsonString js) {js.begin([);size_t n m_vCdn.size();for(int i0; in; i) {CDNINFO c m_vCdn[i];CJsonString cdn;c.format(cdn);js.append_obj(cdn);}js.close(]);} 又如 CJsonString js,list;list.begin([);for (auto it nameVec.begin(); it ! nameVec.end(); it){CJsonString jsObj;std::wstring name *it;if (name L类别)continue;std::string name8 nbase::UTF16ToUTF8(name);jsObj.begin({);jsObj.append_item(name, name8.c_str());jsObj.close(});list.append_obj(jsObj);}list.close(]);js.append_obj(list, list);js.close(});js.WriteFile(d:\\name.json); 三、一个综合例子
{nameArr: [{account: 张三},{account: 王五},{account: 李四}],phoneArr: [{account: 1800000}]
} 1、读JSON std::setstd::wstring acountSet_;std::setstd::wstring acountPhoneSet_;void ReadAcountSet()
{std::string path GetXnwAccountJsonPath();CBinBuf buf;if (buf.Read(path.c_str())){CJsonObj json(buf);int err;CJsonObj* arry json.getObj(nameArr, err);if (arry arry-isarray()){for (int i 0; i arry-get_arry_size(); i){CJsonObj * pJson arry-get_arry_at(i);std::string name;pJson-getString(account, name);if (!name.empty()){std::wstring namew nbase::UTF8ToUTF16(name);acountSet_.insert(namew);}}}arry json.getObj(phoneArr, err);if (arry arry-isarray()){for (int i 0; i arry-get_arry_size(); i){CJsonObj * pJson arry-get_arry_at(i);std::string name;pJson-getString(account, name);std::wstring namew nbase::UTF8ToUTF16(name);acountPhoneSet_.insert(namew);}}}} 2、写JSON
void SaveAcountSet(){std::string path GetXnwAccountJsonPath();CJsonString listJsonStr;listJsonStr.begin({);CJsonString jsonStr;jsonStr.begin([);for (auto it : acountSet_){std::string name nbase::UTF16ToUTF8(it);CJsonString json;json.begin({);json.append_item(account, name.c_str());json.close(});jsonStr.append_obj(json);}jsonStr.close(]);listJsonStr.append_obj(nameArr, jsonStr);CJsonString jsonStr2;jsonStr2.begin([);for (auto it : acountPhoneSet_){std::string name nbase::UTF16ToUTF8(it);CJsonString json;json.begin({);json.append_item(account, name.c_str());json.close(});jsonStr2.append_obj(json);}jsonStr2.close(]);listJsonStr.append_obj(phoneArr, jsonStr2);listJsonStr.close(});listJsonStr.WriteFile(path.c_str());
