  • error C4996: ‘Json::Reader::Char’: Use CharReader and CharReaderBuilder instead

    1、编译下面代码时,遇到标题中的错误

    const char* str = "{"name":"xiaoming","age":18}";  
        Json::Value root;  
        Json::Reader reader;  
        if (!reader.parse(str, root))  
        {  
            cout << "Parse from str failed
    ";  
            return;  
        }  
          
        string name = root["name"].asCString();  
        int age = root["age"].asInt();  
        std::cout << "name: " << name << "  age:" << age;  

    2、解决方法,根据提示修改代码,如下:

        Json::CharReaderBuilder b;
        Json::CharReader* reader(b.newCharReader());
        Json::Value root;
        JSONCPP_STRING errs;
        bool ok = reader->parse(str, str + std::strlen(str), &root, &errs);
        if (ok&&errs.size() == 0)
        {
            std::string upload_id = root["uploadid"].asString();  // 访问节点,upload_id = "UP000000"  
            int code = root["code"].asInt();    // 访问节点,code = 100  
        }
        delete reader;
