My code below crashes(Debug Error! R6010 abort() has been called). Can you help me? I'd also would like to know how to initialize the json object from a string value.
Json::Value obj;
obj["test"] = 5;
obj["testsd"] = 655;
string c = obj.asString();
Hello it is pretty simple:
1 - You need a CPP JSON value object (Json::Value) to store your data
2 - Use a Json Reader (Json::Reader) to read a JSON String and parse into a JSON Object
3 - Do your Stuff :)
Here is a simple code to make those steps:
#include <stdio.h>
#include <jsoncpp/json/json.h>
#include <jsoncpp/json/reader.h>
#include <jsoncpp/json/writer.h>
#include <jsoncpp/json/value.h>
#include <string>
int main( int argc, const char* argv[] )
{
std::string strJson = "{\"mykey\" : \"myvalue\"}"; // need escape the quotes
Json::Value root;
Json::Reader reader;
bool parsingSuccessful = reader.parse( strJson.c_str(), root ); //parse process
if ( !parsingSuccessful )
{
std::cout << "Failed to parse"
<< reader.getFormattedErrorMessages();
return 0;
}
std::cout << root.get("mykey", "A Default Value if not exists" ).asString() << std::endl;
return 0;
}
To compile: g++ YourMainFile.cpp -o main -l jsoncpp
I hope it helps ;)
