如何在使用PHP爬取網站時與頁面元素進行交互？

Question

我需要去http://butlercountyclerk.org/bcc-11112005/ForeclosureSearch.aspx，在字段中輸入數據，然後點擊按鈕來獲得結果。當被帶到結果頁面時，我得到一張數據表，但它分成5個不同的頁面。

我可以使用cURL來完成上述操作，但現在我陷入了困境。

一旦我在結果頁面上，我需要點擊兩次「日期」標題，通過減少日期來制定數據順序，然後取消當天的結果。

任何想法如何做到這一點，先進的細節或概念？無論哪種方式應該幫助。

謝謝！

Answer 1

我無法獲得一組工作結果 - 如果您可以發佈一些可提供結果的虛擬數據，這將有所幫助。

作爲一個通用的答案，您需要一些可以操縱DOM的東西。你可以在服務器端使用PHP和Webdriver，或者使用Selenium作爲客戶端。模擬點擊，得到最終的HTML並解析它。

Answer 2

問題是，點擊實際上是使用javascript執行回發，由於PHP和cURL的限制，您將需要檢查瀏覽器發送的HTTP標頭（GET，POST和COOKIES），並對它們進行模擬。請記住，某些值可能會依賴於會話。現在我沒有時間爲你做這件事，但我知道在某些情況下，ASP.Net網站可能會非常棘手。有可能有更簡單的方法來做到這一點，但這是它總是會下降的，因爲那就是發生了什麼。

如果你沒有綁定到PHP的整個世界的選擇打開 - 例如，我正在處理的項目中的聚合器實際上是能夠執行（受控）的JavaScript專門爲這些類型的任務/頁面（儘管規模更大）。

這應該工作。嘗試這個。
