QT实现上传服务器功能

代码如下所示：

void UploadZipFileToServer(const QString& strPath)
{m_pFile = new QFile(strPath);// 创建HTTP多部份请求QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);QHttpPart keyPart;keyPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant(QString("form-data; name=\"%1\"").arg("id")));keyPart.setHeader(QNetworkRequest::ContentTypeHeader, "text/plain;charset=UTF-8");keyPart.setBody(m_strModelID.toUtf8());multiPart->append(keyPart);QString strMdlName = QFileInfo(strPath).fileName();QHttpPart modelNamePart;modelNamePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant(QString("form-data; name=\"%1\"").arg("name")));modelNamePart.setHeader(QNetworkRequest::ContentTypeHeader, "text/plain;charset=UTF-8");modelNamePart.setBody(strMdlName.toUtf8());multiPart->append(modelNamePart);QHttpPart filePart;filePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant(QString("form-data; name=\"%1\"; filename=\"%2\"").arg("file").arg(m_pFile->fileName())));filePart.setHeader(QNetworkRequest::ContentTypeHeader, "text/plain;charset=UTF-8");m_pFile->open(QIODevice::ReadOnly);filePart.setBodyDevice(m_pFile);m_pFile->setParent(multiPart);multiPart->append(filePart);QHttpPart tokenPart;tokenPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant(QString("form-data; name=\"%1\"").arg("level")));tokenPart.setHeader(QNetworkRequest::ContentTypeHeader, "text/plain;charset=UTF-8");tokenPart.setBody(m_strClassification.toUtf8());multiPart->append(tokenPart);QHttpPart authorizationPart;authorizationPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant(QString("form-data; name=\"%1\"").arg("model")));authorizationPart.setHeader(QNetworkRequest::ContentTypeHeader, "text/plain;charset=UTF-8");authorizationPart.setBody(m_strType.toUtf8());multiPart->append(authorizationPart);QHttpPart metafiled;metafiled.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant(QString("form-data; name=\"%1\"").arg("zone")));metafiled.setHeader(QNetworkRequest::ContentTypeHeader, "text/plain;charset=UTF-8");metafiled.setBody(m_strCooperationZone.toUtf8());multiPart->append(metafiled);//QUrl url("http://192.168.2.59:9090/fileservice/fileupload.do");QUrl url(m_strIp);// 请求URLQNetworkRequest request(url);QNetworkAccessManager *manager = new QNetworkAccessManager();m_pReply = manager->post(request, multiPart);multiPart->setParent(m_pReply);connect(m_pReply, SIGNAL(finished()), this, SLOT(httpUploadFinished()));connect(m_pReply, SIGNAL(uploadProgress(qint64, qint64)), this, SLOT(uploadProgress(qint64, qint64)));QEventLoop eventLoop;connect(manager, SIGNAL(finished(QNetworkReply*)), &eventLoop, SLOT(quit()));eventLoop.exec();
