Qt- Web service Requests



  • I'm trying out web service requests using this site as an example:
    http://www.rcsb.org/pdb/software/rest.do

    I got some GET REST request to work, but I' have no idea how to send the XML POST for its advanced search service. This is what I tried:

    @
    void WindowWrapper::postRequest()
    {
    QNetworkRequest request;

    request.setRawHeader("Content-Type", "text/xml;charset=UTF-8");
    request.setUrl(QUrl(request_url_));
    
    QString query =
            "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
            "<orgPdbQuery>"
            "<queryType>org.pdb.query.simple.StructureIdQuery</queryType>"
            "<description>Simple query for a list of PDB IDs (1 IDs) : 3I5F</description>"
            "<structureIdList>3I5F</structureIdList>"
            "</orgPdbQuery>";
    
    QObject::connect(network_, SIGNAL(finished(QNetworkReply*)),
                     this, SLOT(slotRequestFinished(QNetworkReply*)));
    
    network_->post(request, query.toUtf8());
    

    }

    void WindowWrapper::slotRequestFinished(QNetworkReply* reply)
    {
    if(reply->error() > 0)
    {
    qDebug() << reply->errorString();
    }
    else
    {
    QByteArray data = reply->readAll();

        qDebug() << "Request successful!";
        qDebug() << data;             
    }
    

    }

    @

    And this is how i call the method:

    @
    wrapper_->set_request_url("http://www.rcsb.org/pdb/rest/search/");

    wrapper_->postRequest();
    @

    There's no error on the request, but i get no response at all...

    Does anyone know how can i do this?



  • It seem that the service from that site only accepts application/x-www-form-urlencoded as Content-Type. Now it's working..
