file download
Usually when we write the project will confront the uploading and downloading, after uploading the file path will save the file to the database in order to download, after the station can not figure out if the direct download, you can put the file path to a property tag href;
< A the href = "/ User / Test / xxxx.txt" > Download </ A >
So that when users click on the link to open a browser when it will directly download files.
But there is a situation, such as txt, png, jpg, etc. These browsers support direct open file download task will not be implemented, but will open the file directly, this time on the need to give a label to add an attribute "download";
< A href = "/ the User / the Test / xxxx.txt" download = "filename .txt" > Download </ A >
Here download can not write any information, it will automatically use the default file name
