Documentation says: Paramater: Array (URL-encoded binary contents) One or more image files (submit multiple times to create a slide show) Does anyone know how to do it? 回答1: It's kind of a painful process, but I figured it out after studying the python code Tumblr posted. In short, it requires getting the hexadecimal for the photo and then doing some substitutions. I've created a simple iOS / iPad /

问题 Are there any ways to automatically trim an MP3 uploaded to a website to 30 seconds (or some other length) in PHP? If not, is there any good 3rd party services that could be integrated (transparently to the user) to achieve the same effect? Thanks. 回答1: You could try the MP3 Class on PHPClasses.

问题 I've found a few samples online but I'd like to get feedback from people who use PHP daily as to potential security or performance considerations and their solutions. Note that I am only interested in uploading a single file at a time. Ideally no browser plugin would be required (Flash/Java), although it would be interesting to know the benefits of using a plugin. I would like to know both the best HTML form code and PHP processing code. 回答1: File Upload Tutorial HTML <form enctype="multipart

问题 I'm using AngularJS to interact with a RESTful webservice, using $resource to abstract the various entities exposed. Some of this entities are images, so I need to be able to use the save action of $resource "object" to send both binary data and text fields within the same request. How can I use AngularJS's $resource service to send data and upload images to a restful webservice in a single POST request? 回答1: I've searched far and wide and, while I might have missed it, I couldn't find a

问题 I have a web service that receives data in JSON format, processes the data, and then returns the result to the requester. I want to measure the request, response, and total time using cURL . My example request looks like: curl -X POST -d @file server:port and I currently measure this using the time command in Linux: time curl -X POST -d @file server:port The time command only measures total time, though - which isn't quite what I am looking for. Is there any way to measure request and
