Question

我有以下Qstring

"diskinfo": "Node: ASHUTOSH-PC, Description: Local Fixed Disk, FreeSpace: 420842713088, Name: C:, Size  : 499875049472  Node: ASHUTOSH-PC, Description: CD-ROM Disc, FreeSpace: , Name: D:, Size  :   Node: ASHUTOSH-PC, Description: Local Fixed Disk, FreeSpace: 324858568704, Name: E:, Size  : 487687450624  Node: ASHUTOSH-PC, Description: CD-ROM Disc, FreeSpace: 0, Name: F:, Size  : 553459712",

我需要以下输出

{
  "diskinfo": "Node: ASHUTOSH-PC, Description: Local Fixed Disk, FreeSpace: 420842713088, Name: C:, Size  : 499875049472
              Node: ASHUTOSH-PC, Description: CD-ROM Disc, FreeSpace: , Name: D:, Size  : 
              Node: ASHUTOSH-PC, Description: Local Fixed Disk, FreeSpace: 324858568704, Name: E:, Size  : 487687450624 
              Node: ASHUTOSH-PC, Description: CD-ROM Disc, FreeSpace: 0, Name: F:, Size  : 553459712",
}

这怎么可能？在Qt

以下是我获取Qstring的代码

QString WctUtils::getDiskSpace( )
 {
     static QString diskSpaceCmd ( qgetenv("WINDIR")
                               + "\\system32\\wbem\\wmic logicaldisk get name, freespace, size, description /format:csv");

    QProcess proc;
    QByteArray qba;
    QString out_str;


    proc.start(diskSpaceCmd);

    if(proc.waitForFinished(-1))
        {
         qba = proc.readAllStandardOutput();
         qba = qba.trimmed();
         qba =qba.replace('\r',' ');
         QString myString =qba;

         QStringList myStringList = myString.split("\n");

         QStringList descriptions = myStringList[0].split(",");

         for(int index = 1;index < myStringList.length();index++)
           {
              QStringList data = myStringList[index].split(",");
              QStringList out;
              for(int ind_2 = 0; ind_2 < data.length(); ind_2++)
              out.push_back(descriptions[ind_2] + ": " +data[ind_2]);
              out_str += out.join(", ");
           }


     }

      QString diskSpace(out_str);
      return (diskSpace);
 }

如何使用word＆＃39; node＆＃39;来追加字符串。在qt c ++的新行？

Answer 1

我会在单词＆＃34; Node：＆＃34;上拆分，然后因为拆分会删除你要拆分的内容，在结果中预先发送＆＃34;节点：＆＃34 ;回到每个字符串。你可以通过以下方式做到：

for (int index = 1; index < myStringList.length(); index++)
{
    myStringList[index] = "Node:" + myStringList[index];
}

拆分后向Qstring添加新行
