Detect all the network erroneous cases with Qt



  • detect all the network erroneous cases with Qt

    I want to get Page Source by the following code ,I wonder is it enough to detect all the network erroneous cases with the following code ?
    @
    import sys
    from PyQt4.QtGui import *
    from PyQt4.QtCore import *
    from PyQt4.QtNetwork import *
    import chardet

    def showSrc(reply):
    redirctLocation=reply.header(QNetworkRequest.LocationHeader)
    realUrl=reply.url() if not redirctLocation else redirctLocation
    print(realUrl)

    if (reply.error()!= QNetworkReply.NoError):
        print('11111111', reply.errorString())
        return
    
    content=reply.readAll().data()
    if content==b'':
        print('---------', 'cannot find any resource !')
        return
    
    charCodec = chardet.detect(content)['encoding']
    webPageSRC = content.decode(charCodec)
    print(webPageSRC )
    qApp.quit()
    

    if name == 'main':

    app =QCoreApplication(sys.argv)
    
    manager=QNetworkAccessManager ()
    url =input('input url :')
    
    
    request=QNetworkRequest (QUrl.fromEncoded(QUrl.fromUserInput(url).toEncoded()))
    
    
    request.setRawHeader("User-Agent" ,'Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.57 Safari/537.17 SE 2.X MetaSr 1.0')
    reply=manager.get(request)
    
    manager.finished.connect(showSrc)
    
    app.exec()

  • Enough to do what? You will get every error because you check on !NoError. What else can happen then?

    Please be a bit more specific in your questions. It is hard to help when information is missing!
