PyQt4:从rawHeaderLis中提取值

Question

我想用QNetworkReply读取rawHeaderList的头，如何执行此操作？我尝试迭代，但它说QNetworkRaply对象不可编辑，简单的打印是<PyQt4.QtNetwork.QNetworkReply object at 0x1837958>。在

这是我的密码

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

reply = manager.get(request)

很多方面。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)))

另请参阅QNetworkReply文档，尤其是rawHeader、rawHeaderList、header和其他方法。在

编辑注释：我已经更新了这个示例，使其与较旧的Qt/PyQt版本（4.7之前）兼容。在
