I'm writing an app that talks to Apple to verifyReceipts. They have both a sandbox and production url that you can post to.
When communicating with Apple, if you receive a 21007 status, it means you were posting to the production url, when you should be posting to the sandbox one.
So I wrote some code to facilitate the retry logic. Here's a simplified version of my code:
var request = require('request')
, Q = require('q')
;
| rivets.configure({ | |
| adapter: { | |
| subscribe: function(obj, keypath, callback) { | |
| if (obj instanceof Backbone.Collection) { | |
| obj.on('add remove reset', function () { | |
| callback(obj[keypath]) | |
| }); | |
| } else { | |
| obj.on('change:' + keypath, function (m, v) { callback(v) }); | |
| }; |
| isAnimatedGif = (src, cb) -> | |
| request = new XMLHttpRequest() | |
| request.open "GET", src, true | |
| request.responseType = "arraybuffer" | |
| request.addEventListener "load", -> | |
| arr = new Uint8Array request.response | |
| return cb false if arr[0..3] isnt [0x47,0x49,0x46,0x38] | |
| request.send() |
| require 'should' | |
| http = require 'http' | |
| Vein = require 'vein' | |
| port = Math.floor(Math.random() * 1000) + 8000 | |
| server = new Vein http.createServer().listen port | |
| describe 'first test', (done)-> | |
| it 'should do stuff', (done)-> | |
| server.drop() | |
| server.stack = [] |
