THIS PROJECT HAS MOVED TO GITHUB.

jsoncpp is an implementation of a JSON (http://json.org) reader and writer in C++. JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate.

User Reviews

  • I honeslty consider this app one of the best program I ever used! => consider having a look at this site for Free Goods : www.scripts4geeks.com

  • Robust, small and standard de facto implementation of JSON parser in C++. We use it in educational purposes to study students.

  • We have been using Json-cpp for quite a number of years in our mobile games, where it has provided solid, reliable, cross-platform parsing with a very small footprint.

  • hello author, I find two bug. 1.if json more than twenty value,Could lead to a loss of "[" and "{". example: Json::Value root; Json::FastWriter writer; while(bContinue) { hModule = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, PInfo.th32ProcessID); Module32First(hModule, &MInfo); CloseHandle(hModule); hProcess = OpenProcess(PROCESS_QUERY_INFORMATION,FALSE,PInfo.th32ProcessID); char cFull[1024] = {0}; int iLen = pGetProcessImageFileNameA(hProcess,cFull,1024); Json::Value sysinfo; sysinfo["dwPid"] = (int)PInfo.th32ProcessID; sysinfo["FileName"] = PInfo.szExeFile; sysinfo["FilePath"] = DosDevicePath2LogicalPath(cFull); sysinfo["dwThreads"] = (int)PInfo.cntThreads; sysinfo["dwPriClass"] = (int)GetPriorityClass(hProcess); root.append(sysinfo); bContinue = Process32Next(hSnapshot, &PInfo); } jsondata = writer.write(root); FILE *fp; fp = fopen("aa.txt", "w"); if(fp ==NULL) printf("fails\n"); fprintf(fp, jsondata.c_str()); 2.value["key"] funtion lost aslong(),if value is FileSize. If updated, please notice 674268015@qq.com,Thank you very much.

  • Ca marche nickel , ça marche sous C++ Builder 6 : utilise les : - conteneur : tableau associatif (map), tableau dynamique (vector) de la STL C++ , - flux de chaînes : stringstream (STL C++) , - string (de la STL C++) . Très bien, y a tout ce qu'il fallait utiliser !! Pour info, je récupère les données de production d'une éolienne en JSON sous la forme : {"Items":[{"Power":"0 W"},{"DailyYield":"0 Wh"},{"TotalYield":"404,54 kWh"}]} {"Items":[{"Power":"0 W"},{"DailyYield":"22 Wh"},{"TotalYield":"576,16 kWh"}]} je décode en C++ Builder6 avec : AnsiString reponse ; // contient la donnée de production éolienne au format JSON JSONValue json ; string power, dailyYield, totalYield ; reponse[ reponse.Length() ] = 0 ; // supprime le '\0' de fin de chaîne de caractères json.decode( reponse.c_str() ) ; if( ! json.empty() ) { power = json["Items"] [0] ["Power"].asString() ; dailyYield = json["Items"] [1] ["DailyYield"].asString() ; totalYield = json["Items"] [2] ["TotalYield"].asString() ; } En javascript, pour décoder du JSON, j'utilise la librairie : json.js Merci beaucoup, ça m'a bien aidé , Did
