download

问题 Hi I am trying to download a file from server but at the end of my process I end up with only numbers and some weird characters on my browser. It's not downloading the file. I am using seam and JSF 1.2. Here is my code: public void writeBytesToResponse(UploadDefinition _instance, String path) { FacesContext context = FacesContext.getCurrentInstance(); HttpServletResponse response = (HttpServletResponse) context .getExternalContext().getResponse(); try { byte[] bytes = getFile(path); response

问题 I am using an HttpHandler to serve documents within my ASP.NET web application. I can get it to work just fine with one issue which I can't quite figure out -- the filename isn't retained. For example, if I am trying to serve a document called "New Patient Information Form.docx" and my handler is called "GetDocument.ashx" the file is downloaded as "GetDocument.docx" and "GetDocument(1).docx", "GetDocument(2).docx" etc. each time I download the file. I want to use a handler instead of linking

问题 I want to export html objects from shiny app to pdf. In order to export table, I was using .Rmd template (based on How to make pdf download in shiny app response to user inputs?), however I do not know how to pass html object to PDF in shiny app. Example app: library(shiny) ui <- shinyUI( fluidPage( fluidRow( column(width=4, htmlOutput("Table1"), htmlOutput("Table2"), htmlOutput("Table3") )) ) ) server <- shinyServer(function(input, output, session){ #****************************************

问题 Currently im facing following problem: I have 3 download links in a list. Only the last file in the list is downloaded completely. The others have a file size of one kilobyte.

问题 I generate an in-memory Excel file via pd.ExcelWriter and BytesIO for a click event in my Python3.8 dash app. Everything works as it should be. When I download my file I get this popup message asking me if I would like to continue to download/open the generated file. However, the popup message shows this (I guess base64 encoded) string (or path?), e.g. ...ydaHdjhgk328AAAAnxsAA== and after downloading the download gets a (randomly assigned?) set of characters as the filename (e.g. ZySzsdn1
