Read the HTTP response Header inside the Content - Disposition can get the file name

 
The Content - disposition is an extension of the MIME protocol, the MIME protocol indicates the MIME user agent how to display additional files, when Internet Explorer receiving end, it will activate the file download dialog box, its file name box automatically populate the head of the specified file name, (please note that this is caused by design; Unable to use this feature to save the document to a user's computer, but not ask users to save the position,) 

Server to the client browser to send a file, if it is a browser support file type, typically default browser to open, such as TXT, JPG, etc., can directly display in the browser, if you need to prompt the user to save, to use the Content - the Disposition, and the key is must add attachment: 

The Response. AppendHeader (" the Content - the Disposition ", "legislation; Filename=filename. TXT ");

CodePudding user response:

IdHTTP1. Head (adress);
FileName:=IdHTTP1 Response. ContentDisposition;

The fileSize: IdHTTP1=. The Response. ContentLength;
