Ext. Net implements File Download

 

• Problem description

In the Ext environment, the traditional. net method cannot be used to download files. You can click the Download button without response or garbled characters.

• Cause Analysis

Because EXT. NET performs operations on the foreground in the background, depending on Extjs, that is, it will send Javascript script code to the foreground, if you use the traditional File Download Method on the page, a file stream will be sent to the front-end, Extjs will not be able to correctly identify the file stream, and eventually the file cannot be downloaded.

• Solution

So how can we achieve download in the Ext environment? Instead of downloading files on the home page, you can call another page to download files.

• Home Page

Method 1 (JS Code)

+ filePath;

• Method 2 (C # code)

+ FilePath );

• Download feature page
