前段時間發現項目中的上傳FTP軟件有可能會在從服務器申請斷連時Crash， 所以加了一個Timer。

由于項目代碼行數過大， 此處上傳部分代碼片段。

timeoutTimer = new QTimer();connect(timeoutTimer, SIGNAL(timeout()), this, SLOT(doTimeout()));timeoutTimer->setInterval(4000); case QFtp::Closing:// The connection is closing down, but it is not yet closed. (The state will be Unconnected when the connection is closed.)pMain->debug( "Status(%d) = disconnecting from HOST", type );timeoutTimer->start();break; case QFtp::Unconnected:// There is no connection to the host.pMain->debug( "Status(%d) = disconnected status", type );if ( communicator->isPerforming() ) {communicator->abortRequest(); // abort performing command, maybe done(ERROR) should be called later }timeoutTimer->stop(); //stop timerbreak; /** *@projectName BoeB9Project *@author Hasan **/ void FtpHelper::doTimeout() {pMain->debug("debug154545 timeout !!!!!!!");pMain->sendProxyMessage("MesUPLOADTimeout", ProxyMessage::Notify);timeoutTimer->stop(); }

在此進程發出MesUPLOADTimeout 信息之后， 項目主進程會從代理Proxy中接受此信息并進行處理。

/***@projectName BoeB9Project*@author Hasan**/ void BoeB9QtmCellInlineMain::restartUploader() {QProcess proc;QString c = "taskkill /im uploader.exe /f";proc.execute(c);proc.close();info("********info terminate uploader");QProcess *proc1 = new QProcess(this);proc1->start("cmd.exe", QStringList() <<"/c" << "c:///ORBKwsmcu/bin/start_uploader.bat");delete proc1;info("********info start uploader again"); }

主進程重啟上傳軟件，從而跳過斷連。
