I found that if we load one url with different QWebView objects parallely, we will get identical output: only one of this QWebView will make real request. Here is example:
from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebKitWidgets import QWebView
def load_and_print(url):
view = QWebView()
view.load(QUrl(url))
def on_ready(ok):
print(view.page().mainFrame().documentElement().toPlainText())
view.loadFinished.connect(on_ready)
if __name__ == '__main__':
app = QApplication([])
# This url outputs random number:
url = 'https://www.random.org/integers/?num=1&min=1&max=100&col=1&base=10&format=plain&rnd=new'
load_and_print(url)
load_and_print(url)
app.exec_()
# output:
# 39
# 39
How can we get "fair", unique output for each QWebView object, If url is the same?
PyQt 5.4, windows 7
Solution is to disable cache:
view.page().settings().setObjectCacheCapacities(0, 0, 0)
