Migrate C ++ application from jsoncpp to rapidjson.

[jstechg]

I have to modify a linux C ++ application developed some time ago, which
use the jsoncpp library so that it uses rapidjson instead.

The original application has the following lines of code that make use of jsoncpp:


#include <jsoncpp/json/json.h>

Json::Reader reader;
Json::Value jval_1;

reader.parse(json_str,jval_1)

Json::Value jval_2 = jval_1["descriptor"];
long long lid_1 = jval_2["id1"].asInt64();

const Json::Value& jid_2 = jval_2["id2"];

Json::Value jmsg;
if(!reader.parse(_function1[id2], jmsg))
{
. . .
}

double dvalue = val_1["descriptor"]["tag"].asInt64();


This application compiles correctly and works right.

I need to modify the above lines of code so that they work correctly using the rapidjson library, instead of jsoncpp.

I am not aware of either of these two IDEs and would appreciate any help in this regard.

ITYM "APIs", not "IDEs". HTH.

;)

(I don't know anything about these API's either, so can't help you on that one. Is documentation not available for them?)

Thanks.

I have to study the operation of jsoncpp and rapidjson in two good tutorials or documentation, but I imagine that the change consists first of all in modifying the incude and then they must be simple changes. The problem is that I urgently need to make this modification and I don't have several days to learn how to use both libraries and then make the change. So I appreciate any help.
