Im creating a web extension and porting from XUL. I used to be able to easily read files with
var dJsm = Components.utils.import("resource://gre/modules/Downloads.jsm").Downloads;
var tJsm = Components.utils.import("resource://gre/modules/Task.jsm").Task;
var fuJsm = Components.utils.import("resource://gre/modules/FileUtils.jsm").FileUtils;
var nsiPromptService = Components.classes["@mozilla.org/embedcomp/prompt-service;1"].getService(Components.interfaces.nsIPromptService);
....
NetUtil.asyncFetch(file, function(inputStream, status) {
if (!Components.isSuccessCode(status)) {
return;
}
var data = NetUtil.readInputStreamToString(inputStream, inputStream.available());
var data = window.btoa(data);
var encoded_data_to_send_via_xmlhttp = encodeURIComponent(data);
...
});
This above will be deprecated.
I can use the downloads.download() to know what was the last download but I can NOT read the file and then get the equivalent for encoded_data_to_send_via_xmlhttp
Also in Firefox 57 onwards, means that I have to try to fake a user action by a button click or something, or upload a file.
Access to file:// URLs or reading files without any explicit user input
isnt there an easy way to read the last downloaded file?
