c# - WebDriverException : 'SecurityError: The operation is insecure.' error using document. write() 在 Firefox 中通过 Selenium

Question

我需要在 Firefox selenium 中加载一个页面，然后重写页面的内容，我必须使用 Firefox，所以 Chrome 不是一个选项。

我试过下面的代码

FirefoxDriver firefoxDriver = new FirefoxDriver(new FirefoxOptions() { AcceptInsecureCertificates = true });
            
IJavaScriptExecutor javaScriptExecutor = (IJavaScriptExecutor)firefoxDriver;
firefoxDriver.Navigate().GoToUrl("https://www.google.com");
javaScriptExecutor.ExecuteScript("document.write('a');");

但它给了我错误:

OpenQA.Selenium.WebDriverException: 'SecurityError: The operation is insecure.

`

我需要知道 about:config 中是否有任何选项或任何方式让 Firefox 运行不安全的操作。

Answer 1

文档.write()

Document.write()方法将文本字符串写入文档流，在关闭(已加载)文档上调用 document.write() 会自动调用 document.open()，这将清除文档。

长期以来，firefox和 internet-explorer除了删除所有节点外，还删除了所有 JavaScript 变量。但现在已经不是这样了。然而google-chrome仍然继续这样做。

• 等效的 Python 代码:

  from selenium import webdriver
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
  driver.get("https://google.com")
  driver.execute_script("document.write('a');")

Gecko-specific notes

Starting with Gecko 1.9, this method is subject to the samesame-originpolicyas other properties, and does not work if doing so would change thedocument's origin.

Starting with Gecko 1.9.2, document.open() uses the principal of thedocument whose URI it uses, instead of fetching the principal off thestack. As a result, you can no longer call document.write() into anuntrusted document from chrome, even usingwrappedJSObject.
