[Solved]send QHTTP request with user agent added

redstoneleo

there is an example in C:\Python33\Lib\site-packages\PyQt4\examples\network\http

but I want to add User-Agent header to the http request ,so I commented
@

self.httpGetId = self.http.get(path, self.outFile)

@

and write the following code
@
header = QtNetwork.QHttpRequestHeader("GET", path)#1
header.setValue("Host", url.host())
header.setValue('User-Agent' ,'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.60 Safari/537.17')

    self.http.setHost(url.host())

@

then here is the question ,I don’t know how to Send this request with the header added to the server?

P.S.
I referred the documentation ,found perhaps
int QHttp::request ( const QHttpRequestHeader & header, QIODevice * data = 0, QIODevice * to = 0 )
would come to help me solve this question ,but I wonder what ‘data’ should be in this case ?

You should use "QNetworkAccessManager":http://qt-project.org/doc/qt-4.8/qnetworkaccessmanager.html and it's post()/put()/get() methods instead of QHttp.

@
QNetworkRequest *req(QUrl("http://server.com"));
req->setRawHeader("User-Agent" ,"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.60 Safari/537.17");

QNetworkReply* reply = m_NAM->post(req,DATA);

why does reply.rawHeaderPairs () ==[] here ?
is there something wrong ?
@
import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *
from PyQt4.QtNetwork import *

if name == 'main':

app =QCoreApplication(sys.argv)

manager=QNetworkAccessManager ()
url =input('input url :')

print(QUrl.fromEncoded(QUrl(url).toEncoded()))
request=QNetworkRequest (QUrl.fromEncoded(QUrl(url).toEncoded()))

    
request.setRawHeader("User-Agent" ,'Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1')
reply = manager.head(request)

print(reply.rawHeaderPairs () )
sys.exit()

Because you setting the raw header on the request and checking the reply for the raw header afterwards? :)

Or in case you are wondering why the reply doesn't contain anything at all:
You don't give the reply a chance to receive any data. You need to listen to the finished signal of the reply. The Headers are coming (mostly) with the first chunk of data from the server.
