Hi,
Following is my back end code in python.
def download_key(self):
import cherrypy
cherrypy.response.headers['Content-Type'] =
"application/octet-stream"
cherrypy.response.headers['Content-Disposition'] = 'attachment;
filename="myfile.pem"'
return "These are file content"
And the front end code is as follows in extjs.
function downloadFile(){
var url='/download_key';
var ajaxReq=ajaxRequest(url,0,"GET",true);
ajaxReq.request({
success: function(xhr) {
Ext.MessageBox.alert(_("Success"), xhr.responseText);
},
failure: function(xhr){
Ext.MessageBox.alert( _("Failure") , xhr.statusText);
}
});
}
I am getting response at front end in a message box. But I need that
response text in a file.
Please help me if you know the solution.
Regards,
Sandeep
