使用RequireJS缓存破坏特定模块-CachebustingspecificmoduleswithRequireJS

The cache-busting works by appending an always-unique query string to the end of every file which is required. It makes use of RequireJS's urlArgs config value; RequireJS takes care of appending it for you:

缓存清除的工作原理是将一个始终唯一的查询字符串附加到所需的每个文件的末尾。它利用了RequireJS的urlArgs配置值; RequireJS负责为您追加：

urlArgs: "bust=" + (new Date()).getTime()

The(new Date()).getTime() part is just a simple way to get a unique string out of Javascript. You could do some variation on Math.random(), but using the number of milliseconds since the epoch guarantees uniqueness, for optimum cache-bustage.

（new Date（））。getTime（）部分只是一种从Javascript中获取唯一字符串的简单方法。你可以在Math.random（）上做一些变化，但是使用自纪元以来的毫秒数保证了唯一性，以获得最佳的缓存缺陷。

I think Mr Burke is suggesting something like:

我认为伯克先生建议的事情如下：

require.config({
    baseUrl: '/base/path',
    paths: {
        'fileAlias': 'fileLikelyToChange?bust=' + (new Date()).getTime(),
        'anotherFileAlias': 'anotherFileLikelyToChange?bust=' + (new Date()).getTime(),
        'jQuery': 'jQuery'
    },
});

So, instead of the ubiquitous urlArgs cache-busting, you apply it specifically to each file which is likely to change; hence, excluding any libraries.

因此，不是无处不在的urlArgs缓存破坏，而是将其专门应用于可能会发生变化的每个文件;因此，不包括任何图书馆。

I haven't tested it, but I'd probably tidy it up to something like:

我没有测试过，但我可能会把它整理成类似的东西：

function bust(path) {
    return path + '?bust=' + (new Date()).getTime();
}

require.config({
    baseUrl: '/base/path',
    paths: {
        'fileAlias': bust('fileLikelyToChange'),
        'anotherFileAlias': bust('anotherFileLikelyToChange'),
        'jQuery': 'jQuery'
    },
});

Just remember that if you really need to rely on some external script that you can use $.getScript instead of require to ensure that it's included. I have some non-amd scripts that are for 3rd party integration (e.g. amazon payments), which I used getScript for instead of require. If you can use this method, it would avoid sending the cache busting parameters from urlArgs to the external server.

请记住，如果你真的需要依赖一些外部脚本，你可以使用$ .getScript而不是require来确保它包含在内。我有一些非amd脚本用于第三方集成（例如亚马逊支付），我使用getScript代替require。如果您可以使用此方法，则可以避免将缓存清除参数从urlArgs发送到外部服务器。
