upload

问题 I want to check progress of uploading file by HttpUrlConnection . How I can do this? I've tried to calculate bytes when writing data in OutputStream but it's wrong, cause real uploading happens only when I call conn.getInputStream() , so I need somehow to check inputStream. Here is my code: public static void uploadMovie(final HashMap<String, String> dataSource, final OnLoadFinishedListener finishedListener, final ProgressListener progressListener) { if (finishedListener != null) { new Thread

问题 I need to preview an image prior to submitting a form. I work with Rails 3 and needs something that is browser compatible.

问题 I have an HTML form and I am using Python to generate a log file based on the input. I'd like to also be able to allow the user to upload an image if they choose. I can figure out how to manipulate it with Python once it's there, but I'm not sure how to get the image uploaded. This has most certainly been done before, but I'm having a hard time finding any examples. Can any of you point me in the right direction? Basically, I'm using cgi.FieldStorage and csv.writer to make the log. I want to

问题 Can anyone please tell me how to store images in an oracle database as BLOBs using PHP? A working example would be nice. Thankyou. 回答1: You first need to get the image that is being uploaded from the $_FILES #global array: $image = file_get_contents($_FILES['image_field_name']['tmp_name']); Then to insert the image in the database try this: $sql = "INSERT INTO table (id, image) VALUES(1, empty_blob()) RETURNING image INTO :image"; $result = oci_parse($connection, $sql); $blob = oci_new

问题 I am using RestKit to drive interactions with my web server. I am trying to use routing to POST an Event object to the server with an image attached to it.
