Hello. I am working on parsing json in c++.
json format is

{
{
"product":"12456",
"variant":"5698"
}
,
{
"product":"124565",
"variant":"5698"
}
,
{
"product":"124565",
"variant":"12456"
}
}

I can't find json parser library can parse that format json.

Help me.

Thanks in advance.

I tried with jsoncpp-master, rapidson-master, restful-mapper-master
cpprestsdk-master.

OK, you tried various libraries. Why are they failing?

Member 12179079 19-Apr-16 4:00am

in my mind they can parse {"product:", "123", "product", "1234"}
but can't parse {
{
"product":"12456",
"variant":"5698"
}
,
{
"product":"124565",
"variant":"5698"
}
,
{
"product":"124565",
"variant":"12456"
}
}

if you know the source code of doing that.
teach me.
Thanks.

Why not? That is just an array.

It would be if the enclosing braces were [ and ]

I think the decoder is not the problem, but rather, it's a matter of invalid output produced by the encoder.

Quote:

{
{
"product":"12456",
"variant":"5698"
}
,
{
"product":"124565",
"variant":"5698"
}
,
{
"product":"124565",
"variant":"12456"
}
}

May be all libraries agree that your data is not JSON format.

Didn't try to correct it.
Just a Quote from question.

Perfectly fine with N.B.2 :)

Your json should begin and end in [ ] not { } : JSONLint - The JSON Validator.[^]

JavaScript

[
{
"product":"12456",
"variant":"5698"
}
,
{
"product":"124565",
"variant":"5698"
}
,
{
"product":"124565",
"variant":"12456"
}
]
