1, parsing (JSON string converted to object)

Std::string Strdatajson;

Json::reader Jreader;

Json::value Jobject;

if (! Jreader.parse (Strdatajson, Jobject))

{

Cerr << "Parse json error." << Endl;

return bsuccess;

}

2, read

std::string STRMSG = jrec["msg"].asstring ();

int nretcode = jrec["ret"]. Asint ();

Json::value JList = jrec["Data" ["List"];

int nSize = Jlist.size ();

Get error message: Jreader.getformatederrormessages ()

3, add or modify

jroot["StringData"] = Json::value ("msg");

jroot["Intdata"] = Json::value (10);

4, delete

Jvalue.removemember ("Toberemove");

5, the object is converted to a string

output unformatted JSON string

Json::fastwriter Fast_writer;

Strjreclist = Fast_writer.write (jroot);

JSON after formatting, with carriage return line break

std::string strout = jroot.tostyledstring ();
