Jsoup如何返回頁面內腳本生成的電子郵件ID

Question

我有一個文檔對象為：

Document secDoc = Jsoup.connect(a.attr("abs:href")).timeout(30*1000).get();
String txt = secDoc.text();

現在，當我調試上面的代碼並檢查secDoc的值時，我得到了具有以下元素的普通頁面源：

For questions about your order, including anything shipping or billing related, please email <script type="text/javascript">write_email('oatmealsupport','gmail.com')</script>.

如果您自己看到該網頁，則可以看到以下行： For questions about your order, including anything shipping or billing related, please email oatmealsupport@gmail.com. We only do email support at this time. For questions about your order, including anything shipping or billing related, please email oatmealsupport@gmail.com. We only do email support at this time. 有趣的是，此腳本在頁面上生成電子郵件ID。 在執行檢查元素時，我得到：

<p>
                For questions about your order, including anything shipping or billing related, please email <a href="mailto:oatmealsupport@gmail.com">oatmealsupport@gmail.com</a><script type="text/javascript">write_email('oatmealsupport','gmail.com')</script>.
                We only do email support at this time.<br><br>
                Hours of operation: <strong>Monday-Friday 8am - 6pm PT.</strong>
                <br>
                <strong>Shipping Times</strong>:
                We strive to fulfill the orders within 3-5 working days. When we are really busy we may take a day or two longer. 
              We ship orders Monday - Friday, so if your order is placed Friday evening we may not be able to process it until the following Monday. 
                If we are behind, it may be a few days before we respond.  The Oatmeal is an extremely small operation so please be patient.

因此，錨點： <a href="mailto:oatmealsupport@gmail.com">oatmealsupport@gmail.com</a>由腳本生成。

無論如何，我可以使用Jsoup（或任何其他方式）獲得此錨點嗎？

Answer 1

對於此特定站點，地址的用戶和域部分位於script標記中，因此請選擇script標記，獲取其文本，使用正則表達式解析該文本，並在用戶和電子郵件之間使用@進行連接。 您的選擇器可能只是script:contains(write_email) ，假設在頁面的其他位置未使用write_email 。 這僅是因為地址在文本中是公開的，即使它分為兩部分也是如此。

通常，Jsoup不是JavaScript引擎。 如果您想看到使用Web瀏覽器的人會看到的頁面，則可以嘗試使用Selenium之類的瀏覽器自動化工具。
