My netwok connection always return 202 error in 3G but works fine in wireless

[remi.vanel]

Hi,

I am testing a simple application in QT 4.6. It is working fine in Wifi or in simulator, but I allways have a "202 error : QNetworkReply::ContentOperationNotPermittedError" in 3G mode on the phone (N97 mini).

Here is my sample code :

void Soce::on_okLoginButton_clicked()
{
    QNetworkAccessManager* manager = new QNetworkAccessManager(this);

    QUrl url("http://www.google.fr");
    QNetworkRequest request;
    request.setUrl(url);
    
    connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(nameRetrived(QNetworkReply*)));
    QNetworkReply* reply = manager->get(request);

}

void Soce::nameRetrived(QNetworkReply* reply)
{
 
    if(reply->error() == QNetworkReply::NoError)
    {
       ...
    }
    else
    {
        l_titre->setText("Error : " + QString::number(reply->error()));
    }

    reply->deleteLater();

}

Gives "Error : 202" in 3g or Edge.

Just checking, do you have CAPABILITIES += NetworkServices in your symbian target ?

[remi.vanel]

Yes I have this capability. Thanks

My .pro :

QT       += core gui network


TARGET = Soce
TEMPLATE = app

SOURCES += main.cpp\
        soce.cpp

HEADERS  += soce.h

FORMS    += soce.ui

CONFIG += mobility
MOBILITY =

symbian {
    TARGET.UID3 = 0xeb5c0342
    TARGET.CAPABILITY += NetworkServices
    TARGET.EPOCSTACKSIZE = 0x14000
    TARGET.EPOCHEAPSIZE = 0x020000 0x800000
}

Hm, 202 error in a HTTP request is either a HTTP 403 (Access Denied) or a 405 (Method Not Allowed). Which is kind of weird if you want to get a google search page. Can you try to drop a QWebView in your app just to see what is 'really' shown to the device ?

PS. Try to use a single QNetworkAccessManager for the whole application, creating one every time you press a button can cause problems.

[remi.vanel]

Thanks for your help.
The QWebView works great with exactly the same url !
I just add this line :

ui->webView->setUrl(url);

But I still have the 202 error for the QNetworkReply.
Moving the QNetworkAccessManager in the "Soce::Soce(QWidget *parent)" doesn't change anything...

[remi.vanel]

no one to help me ?

HTTP 202 means OK; accepted for processing, but processing is not completed.

Can you try with some other url and check once.

[remi.vanel]

I tried with many URL with the same result.

For information, the 202 code is the QNetworkReply response code, not the HTTP Status code.
If I ignore this error, I have 403 HTTP error while trying to get reply->attribute(QNetworkRequest::HttpStatusCodeAttribute).toUInt().

One more time : I only have this issue in 3G, it is working fine in Wifi or in simulator.

Thanks for your help

the last code used :

void Soce::on_okLoginButton_clicked()
{

    QUrl url("http://www.nokia.com/landing-page/selected_country");

    ui->webView->setUrl(url);

    QNetworkRequest request;
    request.setUrl(url);

    reply = manager->get(request);

    connect(reply, SIGNAL(finished()), this, SLOT(nameRetrived()));

    l_titre->setText("Getting name for " + e_login->toPlainText());

}

void Soce::nameRetrived()
{
    QString replyString;
    QStringList groupString;

    if(reply->error() == QNetworkReply::NoError)       ////    THE ISSUE IS HERE
    {
        int httpstatuscode = reply->attribute(QNetworkRequest::HttpStatusCodeAttribute).toUInt();
        if(httpstatuscode >=200 && httpstatuscode < 300)
        {
            if (reply->isReadable())
            {
                ........
            }
            else
            {
                replyString = "Ok but non readable";
            }
        }
        if(httpstatuscode >= 300 && httpstatuscode<400)
        {
            replyString = "3xx Redirection";
        }
        if(httpstatuscode >= 400 && httpstatuscode<500)
        {
            replyString = "4xx Error";
        }
        l_titre->setText(QString::number(httpstatuscode) + " return " + replyString);

    }
    else
    {
        l_titre->setText("Error : " + QString::number(reply->error()));
        ui->liste->clear();
        ui->liste->addItem("Ne peut pas récupérer la liste");
    }

    reply->deleteLater();

}

Hello,

I have exactly the same problem. I am using SDK 1.1 and Nokia N8.
Works fine in simulator and Wifi, but I have the same error in 3G.
Capabilities are set and same urls work in phone browser/QWebView.
I tried both with signed and unsigned.

[remy_david]

I changed my SIM for another carrier and now it works.
I am in France, SFR is giving me 202 while it works fine with Orange.
Problem was default QNetworkRequest has an empty user agent, that my carrier proxy was blocking.
Solution:
.h

#include <QWebPage>

class UserAgentProvider : public QWebPage
{
    Q_OBJECT
public:
    explicit UserAgentProvider(QObject *parent = 0);
    QString getUserAgent();
};

.cpp

#include "useragentprovider.h"

UserAgentProvider::UserAgentProvider(QObject *parent) :
    QWebPage(parent)
{
}

QString UserAgentProvider::getUserAgent()
{
    return userAgentForUrl(QUrl(""));
}

UserAgentProvider p;
userAgent = p.getUserAgent();
QNetworkRequest request(url);
request.setRawHeader("User-Agent",userAgent.toAscii());

[remi.vanel]

!!! OK I understand, I'm in the same case !
Thanks SFR.....

But I don't understand why my other N97 apps works, they aren't in QT

[remi.vanel]

Génial, ça marche, enfin ! Merci.

Many Thanks !
It works.

Issue resolved
