file-transfer

问题 Having two devices that need to keep transferring data while in background or in LockScreen. The main resource about backgrounding is available on https://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html So far I'm looking forward to understand how is it expected to implement such above mentioned behaviour: in a scenario where a transfer is in progress and one of the apps (or both) goes into background.

问题 I’m trying to add a function to my application which allow the user to take a picture with his camera or from his smartphone to upload it as a profil picture. I’ve picked this function from another project which is working great but isn’t from me but one of my colleague (he left). I don’t know why since I’ve used the exact same function but the image uploaded look like this : the corrupt image It will randomly start to corrupt the file, generally in the first quarter. One time, it worked but

问题 Since updating my ionic 2 app to release candidate RC0 the Cordova file transfer plugin is no longer working properly. The server doesn't get any of the parameters (params). The relevant part of my code looks like this: var now = Date.now(); const ft = new Transfer(); var options:any; options = { fileKey: "photo", fileName: this.userID + '_' + now + '_' + fileURL.substr(fileURL.lastIndexOf('/') + 1), mimeType: "image/jpeg", params: { user_id: 1, title: this.title, item_type: 'P', latitude:

问题 I apologize if this question was asked elsewhere, but I couldn't find a suitable solution to this vexing problem so here's my situation. I have a node.js script that creates an excel document from scratch and everything is working as expected. However, I'm having trouble saving this newly created file into another remote server which is running ColdFusion (not sure if this matters but i figured I'd at least mention it). The following code produces a request from node.js, but coldfusion keeps

问题 This question already has an answer here : Java socket EOFException (1 answer) Closed last year . What is the easiest way to transfer files over RMI ? 回答1: RMI is a poor choice for this application. There is too much implicit data copying, and too much latency if you use multiple method calls. Use a socket or an HTTP connection. See my answer in this question for a general-purpose solution. I don't know why you are so fixated on using RMI for this. You've posted half a dozen questions on it,

问题 I'm building a pre-deploy script in PowerShell that creates a production build of my .NET Core Web Api application and then SSHs into my Ubuntu Digital Ocean Droplet via SSH key. I'm currently at a stage where I create the build, copy the build folder using Copy-Item , SSH into my server and then this is where I'm completely stuck. I know that I can run BASH commands from my PowerShell script because I've tried some basic operations like creating and deleting a directory, I can cd in and out

问题 I am writing a program that requires the use of XMODEM to transfer data from a sensor device. I'd like to avoid having to write my own XMODEM code, so I was wondering if anyone knew if there was a python XMODEM module available anywhere? 回答1: def xmodem_send(serial, file): t, anim = 0, '|/-\\' serial.setTimeout(1) while 1: if serial.read(1) != NAK: t = t + 1 print anim[t%len(anim)],'\r', if t == 60 : return False else: break p = 1 s = file.read(128) while s: s = s + '\xFF'*(128 - len(s)) chk
