QT实现CSDN上传资源管理助手Demo之（3）请求上传资源页面并解析

请求自己上传的资源页面，只需要请求http://download.csdn.net/my/uploads/就可以了。在请求结果中解析自己的账户相关的信息，比如等级和分数。

发起请求：

void QtResourceAssistant::downloadInfoRequest(int Page){connect(mNetworkAccessManager, &QNetworkAccessManager::finished, this, &QtResourceAssistant::downloadInfoReply);QNetworkRequest NetworkRequest(QUrl("http://download.csdn.net/my/uploads/" + QString::number(Page)));NetworkRequest.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");NetworkRequest.setRawHeader(QByteArray("Referer"), QByteArray("http://download.csdn.net/"));NetworkRequest.setRawHeader(QByteArray("Cookie"), mCookies.toLatin1());mNetworkAccessManager->get(NetworkRequest);}

接收请求信息：

void QtResourceAssistant::downloadInfoReply(QNetworkReply *Reply){disconnect(mNetworkAccessManager, &QNetworkAccessManager::finished, this, &QtResourceAssistant::downloadInfoReply);QString strReply = Reply->readAll();Reply->deleteLater();if (strReply.isEmpty()){QMessageBox::warning(this, tr("警告"), tr("获取下载信息失败，请检查网络并重启软件"), QMessageBox::StandardButton::Close);return;}//mDownloadInfoWidget->setAvatarImage(loadInternetImage(mUserInfoDialog.getAvatar()));mDownloadInfoWidget->setNickName(mUserInfoDialog.getNickName());mDownloadInfoWidget->parseDownloadInfo(strReply);}

解析请求得到的网页信息：

void QDownloadWidget::parseDownloadInfo(QString strInfo){if (strInfo.isEmpty())return;QRegExp rep("http://c.csdnimg.cn/jifen/images/xunzhang/jianzhang/(\\w+).png");rep.indexIn(strInfo);QString TempString = rep.cap();emit loadLevelImageSignal(TempString);rep.setPattern("</label>(.|\n)+MB");rep.indexIn(strInfo);TempString = rep.cap().remove("</label>").remove("\n").remove(" ");mDownloadSizeLabel->setText(tr(QString("上传权限：" + TempString).toStdString().c_str()));rep.setPattern("积分</label><span>(\\d+)");rep.indexIn(strInfo);TempString = rep.cap().remove("积分</label><span>");mDownloadPointsLabel->setText("<h6>积分</h6><h4><font color=orange>"+TempString+"</font></h4>");rep.setPattern("总排名</label><span>(\\d+)");rep.indexIn(strInfo);TempString = rep.cap().remove("总排名</label><span>");mRankLabel->setText("<h6>总排名</h6><h4><font color=\"orange\">" + TempString + "</font></h4>");rep.setPattern("上传资源</label><span>(\\d+)");rep.indexIn(strInfo);TempString = rep.cap().remove("上传资源</label><span>");mDownloadResourceLabel->setText("<h6>上传资源</h6><h4><font color=\"orange\">" + TempString + "</font></h4>");rep.setPattern("下载资源</label><span>(\\d+)");rep.indexIn(strInfo);TempString = rep.cap().remove("下载资源</label><span>");mUploadResourceLabel->setText("<h6>下载资源</h6><h4><font color=\"orange\">" + TempString + "</font></h4>");rep.setPattern("创建专辑</label><span>(\\d+)");rep.indexIn(strInfo);TempString = rep.cap().remove("创建专辑</label><span>");mCreateAlbumLabel->setText("<h6>创建专辑</h6><h4><font color=\"orange\">" + TempString + "</font></h4>");parseUploadResources(strInfo);}void QDownloadWidget::parseUploadResources(QString strInfo){if (strInfo.isEmpty())return;mUploadResourceWidget->clear();//每页5个for (int i = 0; i < 5; i++){QRegExp rep("/download/(\\w+/\\w+)");rep.indexIn(strInfo);QString TempString = rep.cap();if (TempString.isEmpty())break;QListWidgetItem *Item = new QListWidgetItem(mUploadResourceWidget);QResourceItemWidget *ItemWidget = new QResourceItemWidget(mUploadResourceWidget);Item->setSizeHint(QSize(840, 120));connect(ItemWidget, &QResourceItemWidget::downloadResource, this, &QDownloadWidget::downloadResource);connect(ItemWidget, &QResourceItemWidget::deleteResource, this, &QDownloadWidget::deleteResource);mUploadResourceWidget->addItem(Item);mUploadResourceWidget->setItemWidget(Item, ItemWidget);ItemWidget->setResourceUrl(TempString);rep.setPattern("(.+)" + TempString + "\">");rep.indexIn(strInfo);TempString = rep.cap();strInfo.remove(TempString);TempString = strInfo.left(strInfo.indexOf("</a>"));ItemWidget->setResourceName("<h2>" + TempString + "</h2>");TempString = strInfo.left(strInfo.indexOf("brief\">"));strInfo.remove(TempString + "brief\">");TempString = strInfo.left(strInfo.indexOf("</p>")).remove("\n");ItemWidget->setDescription(TempString.left(45) + "...");//标签最多5个TempString = strInfo.left(strInfo.indexOf("下载个数：</label>")) + "下载个数：</label>";strInfo.remove(TempString);TempString = parseTags(TempString);ItemWidget->setTags(TempString);rep.setPattern("\\d+");rep.indexIn(strInfo);TempString = rep.cap();ItemWidget->setDownloadTime("下载个数：" + TempString);TempString = strInfo.left(strInfo.indexOf("上传时间：</label>")) + "上传时间：</label>";strInfo.remove(0, TempString.length());rep.setPattern("(\\d|-)+");rep.indexIn(strInfo);TempString = rep.cap();ItemWidget->setUploadTime("上传时间：" + TempString);TempString = strInfo.left(strInfo.indexOf("所需积分/C币：</label>")) + "所需积分/C币：</label>";strInfo.remove(0, TempString.length());rep.setPattern("\\d+");rep.indexIn(strInfo);TempString = rep.cap();ItemWidget->setNeedScore("所需积分：" + TempString);}}QString QDownloadWidget::parseTags(QString strInfo){QString TempTags = "";for (int i = 0; i < 5; i++){QString TempString = strInfo.left(strInfo.indexOf("/tag/"));strInfo.remove(TempString);if (strInfo.isEmpty())break;TempString = strInfo.left(strInfo.indexOf(">"));strInfo.remove(TempString + ">");TempString = strInfo.left(strInfo.indexOf("</a>"));TempTags.append("<" + TempString + ">");}return TempTags;}

得到的账户信息和上传资源列表，主界面使用QMainWindow，列表显示使用QListWidget+自定义QWidget实现显示。如下图所示：

并且实现了翻页功能，实现很简单只需要请求不同的页面就可以了。因为每一页的链接后面会有一个数字：

直接请求不同的链接，得到页面信息并解析就可以了：

资源列表和账户信息的请求，解析，和显示大致就是这样。
