ftp源代碼下載

❷ 怎麼樣才可以把網站的源代碼下載下來

首先，源代碼有兩個概念。
解析前的源代碼，如ASP/php/ASPX等
解析後的源代碼，即HTML代碼
如果是別人的網站，解析前的代碼一般是弄不到的。
目前所有網站都可以通過瀏覽器中的查看源代碼功能查看。
如果是自己的網站，那麼可以上FTP或者在線文件管理系統下載源代碼或遠程式控制制管理伺服器

❸ 求FTP Server和FTP Client的源代碼，要java或C++的,

❹ 如何把騰訊雲伺服器上的源代碼下載

可以通過伺服器或小插件下載。
如果搭建了ftp服務可以通過ftp，如果只有ssh連接也可以在線安裝一些小插件下載。
騰訊雲雲伺服器是在雲中提供可擴展的計算服務，功能非常強大。

❺ FTP下載下來是網站的源代碼對嗎

是的，FTP下載的就是網站源代碼，但有的網站還有MSSQL或者MYSQL資料庫，這個一般下載不到，即使下載到，重新上傳上去路徑不一定對，資料庫名，用戶名，密碼也不一定對。

❻ 能否給一個java開發的具有圖形界面的ftp伺服器客戶端源代碼呢

❼ 如何把ftp上的源代碼下載下來

這個簡單，在網站根目錄上一級建個文件夾，把選擇網站根目錄後點復制，然後粘貼到新建的文件夾裡面，把文件在裡面壓縮一下，壓縮好後，點擊壓縮文件就會下載了。

下面wwwroot就是下載的壓縮好的源碼

❽ 別人幫我把網站做好了，可是網站的源代碼我不知道 ，我進我的網站的FTP裡面 可以找到並下載嗎

asp和php做的網站可以，因為這兩種開發語言是開源的 。直接到ftp裡面把所有文件下載到本地就可以了。
如果是asp.net或者是jsp開發的話 那麼就要找做網站的人要源碼了 。

PS：asp開發的網站文件後綴是.asp。 php開發的網站文件後綴是.php 。asp.net開發的網站後綴一般為aspx

Good Luck

❾ 如何用ftp下載已上傳的網站的源代碼進行修改

首先你需要知道如下參數：對方的 FTP 伺服器的 IP 地址、用戶名、登錄密碼、對外公用的子目錄和對該目錄的讀寫許可權、以及對外服務的 FTP 埠號（不一定都是標準的埠號）。然後你用 cuteftp、leapftp 等客戶端軟體，在其中設置好以上參數，就可以下載網站的源代碼了。（現在的 FTP 客戶端都支持文件和子目錄的遞歸下載）

❿ 網站遠程伺服器 怎麼下載源代碼

最簡單的，直接打開ftp://網站IP地址，用戶名，密碼就可復制。
最好用FTP工具上傳下載，如leapftp等。
