在加载网页期间打印出所有请求的 URL [英] print out all the requested URLs during loading a web page

问题描述

在我的项目中，有一些需要在加载网页时通过Python在Chrome Dev Tools中获取某个请求的URL，

In my project, there is some need to get a certain requested URL in Chrome Dev Tools by Python during loading a web page,

我认为通过 Qt WebEngine 获取 URL 是一个很好的解决方案.我首先尝试使用下面的代码在加载网页期间打印出所有请求的 URL，但它不起作用 - 根本没有打印 URL，所以这里有什么问题?有什么好的解决办法吗?

I think get the URL by Qt WebEngine is a good solution. I started by trying to use the code below to print out all the requested URLs during loading a web page, but it didn't work - no URL get printed at all , so what's wrong here ? Any good solutions ?

import sys
import os

from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebEngineWidgets import *
from PyQt5.QtWebEngineCore import *
from PyQt5.QtCore import QUrl


class WebEngineUrlRequestInterceptor(QWebEngineUrlRequestInterceptor):
    def __init__(self, parent=None):
        super().__init__(parent)

    def interceptRequest(self, info):
        print(info.requestUrl())


if __name__ == '__main__':
    app = QApplication(sys.argv)
    profile = QWebEngineProfile()
    profile.setRequestInterceptor(WebEngineUrlRequestInterceptor())
    page = QWebEnginePage(profile)
    page.setUrl(QUrl(
        "http://music.163.com/"))

    view = QWebEngineView()

    view.setPage(page)
    view.resize(1024, 600)

    view.show()

    sys.exit(app.exec_())

推荐答案

我在 C++ 中使用 Qt，但在 Python 中应该是类似的，

I use Qt with C++, but in Python should be something similar,

如果你想处理 HTTP/HTTPS url，你可以继承 QWebEnginePage，并重新实现

If you are trying to handle HTTP/HTTPS urls, you could subclass QWebEnginePage, and reimplement

acceptNavigationRequest(const QUrl &url, QWebEnginePage::NavigationType type, bool main).

要使用您自己的 QWebEngineUrlRequestInterceptor，您必须指定您正在使用的协议.C++ 中的示例:

To use your own QWebEngineUrlRequestInterceptor you have to specify the protocol you are using. Example in C++:

const QString EXAMPLE_SCHEMA_HANDLER = "example://" /* http://, https://, mail:// ....   */;
const QWebEngineUrlSchemeHandler* installed =  QWebEngineProfile::defaultProfile()->urlSchemeHandler(EXAMPLE_SCHEMA_HANDLER);
        if (!installed)
            profile()->installUrlSchemeHandler(EXAMPLE_SCHEMA_HANDLER, new WebAppUrlSchemeHandler(this));

Dorry 我不使用 Python，但让我们在 Python 中尝试这样的事情:

Dorry i dont use Python, but lets try something like this in Python:

profile.setRequestInterceptor("https://", WebEngineUrlRequestInterceptor())
