base64

问题 i'm trying to get files from storage folder and converting them into base64 in vue.js. i'm using below method, But it seems not working. public function getImages() { $filesToReturn = []; $files = File::files(storage_path() . "/app/record_keeper"); foreach ($files as $file) { array_push($filesToReturn, $file->getRealPath()); } return response()->json(['files' => $filesToReturn], $this->response_status_code, 200); } returned file urls {"files":["/home/Project/vue_image_previewer/storage/app

问题 I am using Python and I have a base64 string. I want to know that if the base64 data I have received is a image and not any other file (eg. PDF, DOCX) whose extension is changed to image extension. Example: string1 = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAARwAAAD2CAYAAAAEXDiwAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAAAhdEVYdENyZWF0aW9uIFRpbWUAMjAyMDowMToyMyAxODowNjo1NkXosZcAADekSURBVHhe7Z0HuF5VlbDXDSUI0hOQIAqY0EWwjBLEwRFGKXYEQUT8FZixAjP4

问题 I am working on a mobile application(ionic) where there is a field for user's signature. Users needs to sign with their finger in canvas. Now this application has web version, where they used topaz sigweb to do this. Now to save signature and to view in both ends i need some kind of conversion. I checked sigweb's documentation, they save the signature in ASCHII hex format. I am not sure if they are using any kind of internal encryption or not because i can not convert the hex string to any

问题 I am trying to decode base64 encoded string into bitmap in android. The encoded string will start with "image/jpeg;base64," I use the following method: public static Bitmap decodeBase64(String input) { byte[] decodedByte = Base64.decode(input, Base64.DEFAULT); // also tried using Base64.URL_SAFE , Base64.NO_PADDING return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length); } Assume that I am calling the above method as ImageView get_img=(ImageView)fundViewByID(R.id.getImg); get
