推送无效(错误:无法获取) [英] Push doesn't work (Error: Could not get)

问题描述

尝试使用Ratchet的push.js，但不起作用. 我在控制台中拥有什么:

Trying to use Ratchet's push.js, but doesn't work. What I have in console:

[Error] Error: Could not get: file:///var/mobile/Applications/337585D8-89E1-4810-AB37-0A6DD2DA3A34/Gustav.app/www/booking.html
failure (ratchet.js, line 446)
onreadystatechange (ratchet.js, line 371)

如果您十次点击链接，您将开始收到以下消息:

If you will tap link like ten times you start to receive this:

[Error] TypeError: 'undefined' is not an object (evaluating 'cacheMapping[PUSH.id].url')
cachePush (ratchet.js, line 202)
PUSH (ratchet.js, line 392)
touchend (ratchet.js, line 258)

所有这些来自真实设备测试(iOS 7.1)的控制台数据，包装器都是Cordova CLI 3.4.1-0.1.0.

All this console data from real device tests (iOS 7.1), wrapper is Cordova CLI 3.4.1-0.1.0.

文件booking.html存在，像这样的本地野生动物园失败

File booking.html exist, native safari failure like this

[Error] Failed to load resource: The requested URL was not found on this server. (menu.html, line 0)

没有出现.

推荐答案

push.js不支持file://协议.

push.js does not support file:// protocol.

Ratchet使用XHR请求来获取内部的其他页面 应用.出于安全考虑，现代浏览器无法使用XHR 在本地打开文件时(也使用file://协议)请求； 因此，直接作为文件打开时，Ratchet不起作用.一种 常见的解决方案是简单地从本地提供文件 服务器.实现此目的的一种简便方法是运行python -m SimpleHTTPServer来提供当前目录中的文件 到http://localhost:<port>

Ratchet uses XHR requests to fetch additional pages inside the application. Due to security concerns, modern browsers prevent XHR requests when opening files locally (aka using the file:// protocol); consequently, Ratchet does not work when opened directly as a file. A common solution to this is to simply serve the files from a local server. One convenient way to achieve this is to run python -m SimpleHTTPServer to serve up the files in the current directory to http://localhost:<port>
