qt代码在编写json字符串是碰到了双引号中的双引号这个时候会报错

QString commandStr =
            "insert into student_info.json_user values (\
            null, '{\
               "name":"lison",\
            "age":18,\
            "address":"enjoy"\
               }' );";

解决方法：对双引号进行转义

QString commandStr =
            "insert into student_info.json_user values (\
            null, '{\
               \"name\":\"lison\",\
            \"age\":18,\
            \"address\":\"enjoy\"\
               }' );";
