有人可以从服务器外部知道目录中的文件吗？

Question

I have web application that will store some files inside a directory called items, and each item will have it's own directory.

The question is if the directory has an index.html page can anyone knows what the names of files might be ?

more explanation

 http://www.mysite.com/items/item-734783HH/

inside item-734783HH there will be 2 files

 -index.html
 -secureFile.zip

The secureFile name will be hashed. Is there anyway to steal this file from the web ? that's my real concern

Also, I am using PHP for copying this file and give it to the user when the purchase is complete.

Answer 1

short answer, but only "usually" true: no.

long version for the short version: if you have an index.html then going to http://www.mysite.com/items/item-734783HH/ will serve up http://www.mysite.com/items/item-734783HH/index.html instead. Users will not see a directory listing, so they either have to know those files already exist, or guess them.

actually true answer: only you can tell us. It depends on the server you're using in combination with PHP, and what you've told it to autoresolve to when someone hits a route that does not indicate a file but a directory. It also depends on whether you blacklist/whitelist files based on file patterns, like a "DENY FROM ALL" for files that start with ".", etc.

It's probably time to learn more about how your server works. The internet has a lot of good information on that.
