如何從所有孫子目錄wget的文件

Question

我有一個網站：http://www.example.com/

這個網站有一個子目錄：http://www.example.com/images/

該子目錄包含它們的內部與圖像衆多子目錄：

• http://www.example.com/images/01
  • http://www.example.com/images/01/img1.png
  • http://www.example.com/images/01/img2.png
  • http://www.example.com/images/01/img3.png
• http://www.example.com/images/02
  • http://www.example.com/images/02/img1.png
  • http://www.example.com/images/03/img2.png
  • http://www.example.com/images/04/img3.png
• http://www.example.com/images/03
  • 等

當我嘗試從images目錄wget，它下載每個目錄（01/，02/等）和index.html每一個的內部。它不下載任何圖像。例如

wget -r http://www.example.com/images/ < - 不下載的PNG

wget -r http://www.example.com/images/01/ < - 不下載的PNG

如何使用wget下載所有從images/目錄下的所有子目錄png•不用通過每個子目錄中去（01 /，02 /，03 /等）一個接一個？

Answer 1

您只需要按照您的要求查看man wget以查找選項。隨着快速查找，我發現這些，

-A acclist --accept acclist   
     Specify comma-separated lists of file name suffixes or patterns to 
     accept or reject. 

--no-directories 
     Do not create a hierarchy of directories when retrieving recursively. 
     With this option turned on, all files will get saved to the current directory, 
     without clobbering (if a name shows up more than once, the filenames will get extensions .n). 

Recursive Retrieval Options 
-r 
--recursive 
     Turn on recursive retrieving. The default maximum depth is 5. 

結合這些結合在一起，你可以把一個命令

wget -nd -r -A png http://www.example.com/images/
