PyQt4：從rawHeaderList提取值

Question

我想從rawHeaderList使用QNetworkReply讀取標題如何執行此操作？我嘗試迭代，但它說QNetworkRaply對象不可迭代，簡單打印表示<PyQt4.QtNetwork.QNetworkReply object at 0x1837958>。

這裏是我的代碼

 

... 
request = QNetworkRequest(QUrl('http://www.kg')) 
manager = QNetworkAccessManager() 

reply = manager.get(request)

方法很多。您可以使用reply.rawHeaderPairs()，例如：

import pprint, sys 
from PyQt4 import QtCore, QtNetwork 

app = QtCore.QCoreApplication(sys.argv) 
request = QtNetwork.QNetworkRequest(QtCore.QUrl("http://stackoverflow.com")) 
manager = QtNetwork.QNetworkAccessManager() 
reply = manager.get(request) 
while not reply.isFinished(): 
    app.processEvents() 

try: 
    # for Qt 4.7 and higher: 
    pprint.pprint(reply.rawHeaderPairs()) 
except AttributeError: 
    # for Qt < 4.7: 
    for header in reply.rawHeaderList(): 
     pprint.pprint((header, reply.rawHeader(header))) 

又見QNetworkReply文檔，尤其是rawHeader，rawHeaderList，header等方法。

編輯說明：我已經更新了示例以使其與舊版Qt/PyQt版本兼容（4.7版之前）。
