我正在尝试使用 selenium 从指定的 URL 将源代码捕获到 HTML 文件中,但我不知道为什么,我没有得到我们从浏览器中看到的确切源代码。
下面是我在 HTML 文件中捕获源代码的 java 代码
private static void getHTMLSourceFromURL(String url, String fileName) {
WebDriver driver = new FirefoxDriver();
driver.get(url);
try {
Thread.sleep(5000); //the page gets loaded completely
List<String> pageSource = new ArrayList<String>(Arrays.asList(driver.getPageSource().split("\n")));
writeTextToFile(pageSource, originalFile);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("quitting webdriver");
driver.quit();
}
/**
* creates file with fileName and writes the content
*
* @param content
* @param fileName
*/
private static void writeTextToFile(List<String> content, String fileName) {
PrintWriter pw = null;
String outputFolder = ".";
File output = null;
try {
File dir = new File(outputFolder + '/' + "HTML Sources");
if (!dir.exists()) {
boolean success = dir.mkdirs();
if (success == false) {
try {
throw new Exception(dir + " could not be created");
} catch (Exception e) {
e.printStackTrace();
}
}
}
output = new File(dir + "/" + fileName);
if (!output.exists()) {
try {
output.createNewFile();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
pw = new PrintWriter(new FileWriter(output, true));
for (String line : content) {
pw.print(line);
pw.print("\n");
}
} catch (IOException ioe) {
ioe.printStackTrace();
} finally {
pw.close();
}
}
有人可以解释一下为什么会发生这种情况吗?WebDriver 如何呈现页面?以及浏览器如何显示来源?
