推荐答案

您可以使用像cURL这样的库来请求带有iPhone用户代理的页面，并将该页面返回到您的站点（请务必扩展相对使用DOMDocument的绝对URL。

You could use a library like cURL to request the page with the iPhone user agent, and return that page to your site (be sure to expand relative URLs to absolute, with DOMDocument).

但是，您可能遇到通过用户代理以不同方式提供CSS / JavaScript /图像的边缘情况。这可能不值得为这些机会申请这些资产。您可以通过向用户代理请求一次，然后使用iPhone用户代理，执行 md5_file（）并查看它们是否不同来限制工作。我不会打扰：P

However, you may run into edge cases where CSS/JavaScript/images are served differently via the user agent. This is probably not worth requesting each of these assets on the off chance. You could limit the work by requesting once with your user agent, and then the iPhone user agent, doing md5_file() and seeing if they are different. I wouldn't bother though :P

你也可以尝试这个JavaScript ......

You could also try this JavaScript...

navigator.__defineGetter__('userAgent', function(){
    return 'foo' // customized user agent
});

navigator.userAgent; // 'foo'

另外请记住，如果您的用户不在，您可能需要发出警告使用Safari，它最接近模拟Mobile Safari。

Also remember you may want to give a warning if your users aren't using Safari, which will be the closest to simulate Mobile Safari.
