使用boost解析有中文的json

代码

// 解析JSON
void TestBoostJson() 
{
    std::cout << "TestBoostJson" << "\n";
    // serialize
    boost::json::object org;
    org["name"] = "你好啊\\ AA BB CC 联通 鸡蛋灌饼 ！（）";
    std::cout << "name:\t"<<org["name"] << "\n";
    auto szJson = boost::json::serialize(org);
    std::cout << "json:\t" << szJson << "\n";
    // parse
    boost::json::error_code ec;
    boost::json::parse_options opt;                    
    opt.allow_comments = true;                          
    opt.allow_trailing_commas = true;                   
    opt.allow_invalid_utf8 = true;                      
    auto obj = boost::json::parse(szJson, {}, opt);
    std::string name = obj.as_object()["name"].as_string().c_str();
    std::cout << "name:\t" << name << "\n";
    return;
}
// 解析UTF8的JSON
void TestBoostJsonUTF8()
{
    std::cout << "TestBoostJsonUTF8" << "\n";
    auto name = "你好啊\\ AA BB CC 联通 鸡蛋灌饼 ！（）";
    std::cout << "name:\t" << name << "\n";
    // utf8 
    auto utf8 = boost::locale::conv::between(name, "UTF-8", "GBK");
    std::cout << "utf8 name:\t" << utf8 << "\n";
    // serialize 
    boost::json::object utf8Ojb;
    utf8Ojb["name"] = utf8;
    auto szJson = boost::json::serialize(utf8Ojb);
    std::cout << "utf8 json:\t" << szJson << "\n";
    // parse 
    boost::json::error_code ec;
    boost::json::parse_options opt;
    opt.allow_comments = true;
    opt.allow_trailing_commas = true;
    opt.allow_invalid_utf8 = true;
    auto obj = boost::json::parse(szJson, {}, opt);
    name = obj.as_object()["name"].as_string().c_str();
    std::cout << "utf8 name:\t" << name << "\n";
    auto gbk = boost::locale::conv::between(name, "GBK", "UTF-8");
    std::cout << "gbk name:\t" << gbk << "\n";
    return;
}


int main(int argc, char** argv)
{
    TestBoostJson();
    TestBoostJsonUTF8();
    return 0;
}
