[SOLVED]How retrive Data from QList< QPair<QString, QString> > tokens = getTokenUrl.queryItems(); and Copy to QString

yravi

Hi ALL,

i have written a webserver program in Qt using Qhttp, where in a form the user will enter the data in textboxes and submit it, as per the below program i am receiving each text box data in "QList< QPair<QString, QString> > tokens" term, and on using QMultimap (suggested by another forum thread) used it, but i can only access the one text box data only. Now i requite the entire data to be copied to QString of the specific as shown in below Code

Code:
@ QUrl getTokenUrl(req->url());

    QList< QPair<QString, QString> > tokens = getTokenUrl.queryItems();

      qDebug() << "tokens size"<< tokens.size();
      qDebug() <<"tokens data"<< tokens;

      QMultiMap<QString, QString> queryParams1;

      QPair<QString, QString> tokenPair1;

      foreach (tokenPair1, tokens) {
          queryParams1.insert(tokenPair1.first.trimmed(), tokenPair1.second.trimmed());
      }

      qDebug() <<"data2"<<queryParams1;


      QString user =tokenPair1.first;
      QString userdata =tokenPair1.second;

// QString password =tokenPair2.first;
// QString passworddata =tokenPair2.second;

       qDebug() <<"user"<< user;
       qDebug() <<"userdata"<< userdata;

// qDebug() <<"password"<< password;
// qDebug() <<"passworddata"<< passworddata;

     resp->setHeader("Content-Type", "text/html; charset=ISO-8859-1");
     resp->writeHead(200);
     resp->write("&lt;html&gt;&lt;head>&lt;title&gt;Greeting App&lt;/title&gt;&lt;/head>&lt;body&gt;");
     resp->write("&lt;form name=\"input\" action=\"\" method=\"GET\"&gt;");
     resp->write("Username: &lt;input type=\"text\" name=\"user\"&gt;&lt;br>");
     resp->write("Password: &lt;input type=\"text\" name=\"password\"&gt;&lt;br>");
      resp->write("date: &lt;input type=\"text\" name=\"date\"&gt;&lt;br><br>");
     resp->write("&lt;input type=\"submit\" value=\"submit\"&gt;");
     resp->write("&lt;/form&gt;");
     resp->write("&lt;/body&gt;&lt;/html>");
     resp->end();@

Current Result:*

tokens size 3
tokens data (QPair("user","1") , QPair("password","2") , QPair("date","3") )
data2 QMap(("date", "3")("password", "2")("user", "1"))
user "date"
userdata "3"

Not quite clear on what output you require. Let me try answering. It is a QList with QPair. I feel you can iterate over the QList and get each QPair Item. From each Pair Item you construct whatever the QString you require.

Hi Dheerendra

can u please provide sample code how to iterate through QList and get each Qpair item. and save it in another QString or QByteArray.

My requirement is i am getting the text box data from the form on submit button is clicked through html code into QList< Qpair <QString,QString> >, and i can watch it on terminal, now i want to analyze the data and transmit over the serial port. For that purpose i have to store the data in a another QString. Pls Guid for this

dheerendra

Try this.

@ QList<QPair<QString, QString> > list;

list.append(qMakePair(QString("PthinkS"),QString("Bengaluru")));
list.append(qMakePair(QString("PthinkS"),QString("India")));
list.append(qMakePair(QString("Dheeru"),QString("Bengaluru")));

qDebug() << "List Count "<<list.count();
for (int i=0;i<list.count();i++){
    QPair<QString, QString> pair = list.at(i);
    qDebug() << pair.first << " " << pair.second;
}@

@dheerendra

Thank you got the values into the QString as per the below code, can u please suggest is it the right way of implementation, pls provide your email id or telephone number for communication i am very much interested in learning Qt--
@
@QString user;
QString userdata;
QString password;
QString passworddata;
QString date;
QString datedata;

QList<QPair<QString, QString> > list= getTokenUrl.queryItems();;

      qDebug() << "List Count "<<list.count();
      for (int i=0;i<list.count();i++){
          QPair<QString, QString> pair = list.at(i);
          if(i==0)
          {
              qDebug() << "i=0 came";
               user =pair.first;
               userdata =pair.second;
          }

          if(i==1)
          {
              qDebug() << "i=1 came";
               password =pair.first;
               passworddata =pair.second;
          }

          if(i==2)
          {
              qDebug() << "i=2 came";
               date =pair.first;
               datedata =pair.second;
          }
          qDebug() << pair.first << " " << pair.second;
      }

       qDebug() <<"user"<< user;
       qDebug() <<"userdata"<< userdata;
       qDebug() <<"password"<< password;
       qDebug() <<"passworddata"<< passworddata;
       qDebug() << "Date"<< date;
       qDebug() << "DateDate"<<datedata;@@@
