Have you ever met such a site? ArticleThe system uses the HTML file generated statically by FSO to display the file. This can reduce the server load and increase the access speed. Second, it also stops SQLInjection attacks. Let me talk about their article system principle: all the articles are inDatabaseThere is a copy. In addition, an HTML page is generated based on the template. Attack method: Check the source file/check whether there is a page called through Js. For example, call to update t
The Os.walk method is used primarily to traverse subdirectories and sub-files within a directory.Can get a ternary tupple (Dirpath, Dirnames, filenames),The first is the starting path, the second is the folder under the starting path, and the third is the file under the starting path.Dirpath is a string that represents the path to the directory,Dirnames is a list that contains the names of all subdirectories under Dirpath.Filenames is a list that contains the name of a non-directory file.These n

"MEN" label in the navigation bar. In this year's April 17 message, Old Navy highlighted the Sales area label HSN uses the same technique, but goes a step further and prompts the sales area focus in the sender's name. For example, in any mail that comes from a specific transaction in its clearance sales area, the sender's name is "HSN clearance" and the "clearance" label is highlighted in the navigation bar. Similar to Old Navy, in the April 19 message, HSN uses the background color to highl

In RangeSet of Guava learning, we talked about the features and usage of RangeSet. There are many differences between RangeMap and RangeSet.On the official API of Google Guava, we can know that RangeMap is a collection type that does not intersection and is not an empty Range (key) map to a Value ). Unlike RangeSet, RangeMap cannot merge adjacent intervals even if the ing value is the same.Like RangeSet, RangeMap is also an interface that implements only two classes, mmutableRangeMap and TreeRan
