Json::Value data;
Json::Reader reader;
if (!reader.parse("111", data, false))
{
printf("Parse failed!!!\n");
return 0;
}

I did test with following case:
"aaa" return false (OK)
"a1" return false (OK)
"1a" return true (Incredible)
"-aa1" return true (Incredible)
So, I think this is jsoncpp bug, could you help me to check it?

Try it with strict-mode.

• http://open-source-parsers.github.io/jsoncpp-docs/doxygen/class_json_1_1_char_reader_builder.html

Json::CharReaderBuilder rbuilder;
Json::CharReaderBuilder::strictMode(&rbuilder._settings);

std::string errs;
Json::Value root;
bool ok = Json::parseFromStream(rbuilder, std::cin, &root, &errs);

thanks for cdunn2001
I improved my code as following:

    Json::Reader reader(Json::Features::strictMode());
    Json::Value root;
    if (!reader.parse(sDoc, root, false))
    {
        printf("Parse %s failed!!!\n", sDoc.c_str());
        return false;
    }
    if (root.empty())
    {
        printf("Empty Json Data!!!\n");
        return false;
    }
