这段代码是向一个网址发送字符串是吗？ [复制链接]

req.setUrl(QUrl("https://reg.163.com/logins.jsp"));
                       req.setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");
                       req.setHeader(QNetworkRequest::ContentLengthHeader,contentLength);
                            QNetworkReply *m_reply = manager->post(req,QByteArray(QString("username=aaaaaaaa&password=bbbbbbb").toAscii()));

这段代码是向一个网址https://reg.163.com/logins.jsp发送字符串("username=aaaaaaaa&password=bbbbbbb").是吗？
为什么用http抓包工具 什么都没有看到发出去呢？？求救  各位大哥

QNetworkRequest req;
                       QNetworkAccessManager *manager;
      
manager = new QNetworkAccessManager();
req.setUrl(QUrl("https://reg.163.com/logins.jsp"));
req.setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");

QNetworkReply *m_reply = manager->post(req,QByteArray(QString("username=bin201&password=jlb7333333").toAscii()));

请教大侠  为什么post不出去数据呢 用http抓包工具始终看不到发出去，这一小段关于qnetwork的post程序有问题吗???
