如何使用QNetworkAccessManager将数据发布到URL

我有一个Web服务，我需要发布一些数据才能使用Qt. 我认为在发布到Web服务时可以使用QByteArray.

I have a webservice that I need to POST some data to using Qt. I figured that I can use a QByteArray when POSTing to the web service.

我的问题是，如何格式化该数组以便在另一端正确解析?

My question is, how can I format this array in order to be parsed correctly at the other end?

这是我到目前为止的代码:

This is the code I have so far:

    // Setup the webservice url
    QUrl serviceUrl = QUrl("http://myserver/myservice.asmx");
    QByteArray postData;

   /* 
   Setup the post data somehow
   I want to transmit:
   param1=string,
   param2=string
   */

    // Call the webservice
    QNetworkAccessManager *networkManager = new QNetworkAccessManager(this);
    connect(networkManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(serviceRequestFinished(QNetworkReply*)));
    networkManager->post(QNetworkRequest(serviceUrl), postData);

谢谢！
