如何解决 Pyqt5 create web browser when load html crash

Question

我用 PyQt5 创建了一个网络浏览器，如果我加载 url="http://www.google.com" 没有任何问题，但是如果我加载 url = "http://192.168.0.106/get.html" ，运行代码，小部件崩溃。

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtWebEngineWidgets import *
import sys  

class MainWindow(QMainWindow):
    """docstring for MainWindow"""
    def __init__(self, *arg,**kwargs):
        super(MainWindow, self).__init__(*arg,**kwargs)
        self.setWindowTitle("Load huobi exchange bar")

        self.browser = QWebEngineView()
        self.browser.setUrl(QUrl("http://192.168.0.106/get.html"))

        self.setCentralWidget(self.browser)


app = QApplication(sys.argv)

window = MainWindow()
window.show()

app.exec_()

下面是get.html

的内容

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>huobi exchange bar</title>
</head>
<body>
  <!-- TradingView Widget BEGIN -->
  <div class="tradingview-widget-container">
    <div class="tradingview-widget-container__widget"></div>
    <div class="tradingview-widget-copyright"><a href="https://cn.tradingview.com/crypto-screener/" rel="noopener" target="_blank"><span class="blue-text">sample</span></a>TradingView</div>
    <script type="text/javascript" src="https://s3.tradingview.com/external-embedding/embed-widget-screener.js" async>
    {
    "width": 1100,
    "height": 512,
    "defaultColumn": "overview",
    "defaultScreen": "general",
    "market": "crypto",
    "showToolbar": true,
    "colorTheme": "dark",
    "locale": "zh_CN"
  }
    </script>
  </div>
  <!-- TradingView Widget END -->
</body>
</html>

我的问题是：如何解决加载异步 js 时 window 崩溃？

Answer 1

我不明白为什么应用程序会损坏，因为即使 url 不存在，这也应该向您显示错误页面，所以如果您想了解错误的更多详细信息，您应该运行 console/CMD.

中的代码

另一方面，您没有指明任何服务器执行 HTML，此外，没有必要使用“http://192.168.0.106”主机，只需将其作为本地文件加载即可：

├── get.html
└── main.py

import os
import sys

from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtWebEngineWidgets import QWebEngineView


class MainWindow(QMainWindow):
    """docstring for MainWindow"""

    def __init__(self, *arg, **kwargs):
        super(MainWindow, self).__init__(*arg, **kwargs)
        self.setWindowTitle("Load huobi exchange bar")

        self.browser = QWebEngineView()

        current_dir = os.path.dirname(os.path.realpath(__file__))
        filename = os.path.join(current_dir, "get.html")
        url = QUrl.fromLocalFile(filename)
        self.browser.setUrl(url)

        self.setCentralWidget(self.browser)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())
