  • 字符串写入到json文件

    背景: PHP产生公告 ,发送到CGI ,在CGI把该公告的json 字符串写入到文件内(转义后的字符串)

    通过 jsoncpp 操作

        int write_notice_to_json(string str_path, const string& str_content)
        {  
            Json::Reader reader;
            Json::FastWriter writer;
            Json::Value root;
            if (false == reader.parse(str_content, root))  // reader将Json字符串解析到root,root将包含Json里所有子元素
            {
                return  RESULT_ERROR; 
            } 
    
            std::string json_file = writer.write(root);
            ofstream ofs;
            ofs.open(str_path.c_str(), ofstream::out);
            if (ofs.is_open())
            {
                ofs << json_file;
                ofs.close(); 
                return  RESULT_OK;
            } 
            return  RESULT_ERROR;
        }  

    今天来到公司终于搞定了  mark一下

    收到的字符串内容:

    {"Notice":{"NoticeVersion":"1414","noticeContent":[{"Image":"notice\/notice01","ImageWidth":"350","ImageHeight":"5"},{"Image":"notice\/notice02","ImageWidth":"350","ImageHeight":"5"},"jghjfghjfghj"]}}

    存到文件后

    踩的坑:一开始想通过C++ 替换掉转义字符串 但是不起作用

     CStringUtils::Replace(m_str_content, "\"", """);
    

     //====================================================================================

    补充:

    之后调整发现,上面的全是费工夫,直接写入到文件就行了,写入文件之后,如果字符串内容是json,那就可以直接解释成json了

     1     int write_notice_to_txt(string str_path, const string& str_content)
     2     {
     3         ofstream ofs;
     4         ofs.open(str_path.c_str(), ofstream::out);
     5         if (ofs.is_open())
     6         {
     7             ofs << str_content;
     8             ofs.close();
     9             return  RESULT_OK;
    10         }
    11         return  RESULT_ERROR;
    12     }
