问题 Is there a reason to still use the FileTransfer object with the availabilty of sending blobs/files or even multiple files in forms via XmlHttpRequest2 ? Using html5 makes it a lot easier to run the same app in a modern browser as well and reduces code. Or are there any advantages to the FileTransfer object? Especially FormData seems to do the same, though it runs only on the latest browsers. 回答1: It seems the FormData & file implementation is not working properly on all systems, yet.

So when I open the inputstream using entity.getContent() I end up writing all of this data to my zip file whereas I only wish to write one part "Payload". I have searched and do not see anyway to obtain just the one individual part from the content. Code is below: HttpResponse response = services

问题 I have a file upload form that is being posted back to a servlet (using multipart/form-data encoding). In the servlet, I am trying to use Apache Commons to handle the upload. However, I also have some other fields in the form that are just plain fields. How can I read those parameters from the request?
