我正在編寫一些代碼，它將搜索網站並返回搜索結果的數量。有點像這樣Number of Google Results from Excel但我正在使用的網站是sciencedirect.com如何創建網站的搜索URL使用<select>
科學直接有點奇怪，因爲結果頁面的網址不包含搜索詞，所以找到發送您的搜索詞的URL是更復雜。我一直在讀高級搜索頁面的源代碼，這是代碼的相關部分：

哪個應根據我的標準搜索「測試」，不幸的是它會返回一個錯誤「必須選擇一個源」，源設置爲URL的Subscribed = 0部分，似乎正在工作，因爲改變價值ch時代來源。
源等領域之間的區別在於源是它採用不
所以我的問題是我怎麼更改URL，使其返回結果。
查詢得到處理在哪裏？你能告訴我們那個代碼嗎？ – Ryan
OP只是想「調用」sciencedirect.com搜索，據我所知。 – codeling
這也是我的問題，如果'source'字段使用'$ _POST'變量而不是'$ _GET'變量，這可能會導致程序停止。另外，在重新閱讀這個問題時，我意識到sciencedirect.com可能不是falcs projet--這就是我最初的看法。 – Ryan
