Google Plusbutton代码在Chrome中警告:“不安全的JavaScript尝试访问框架”

我正尝试在我的网站上添加一个Google Plusbutton,尽pipe我在Chrome上使用了Google推荐的代码,但仍然不断收到JavaScript安全警告。

我用直接从Google网站pipe理员的推荐代码复制的代码复制了错误,没有其他补充:

<html itemscope itemtype="http://schema.org/"> <head> <meta itemprop="name" content="Title"> <meta itemprop="description" content="Description"> </head> <body> <g:plusone annotation="inline"></g:plusone> <script type="text/javascript"> (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')\[0\]; s.parentNode.insertBefore(po, s); })(); </script> </body> 

在Chrome中加载(Mac上为15),开发者控制台警告:

 Unsafe JavaScript attempt to access frame with URL http://mydomain.com/ from frame with URL https://plusone.google.com/_/+1/fastbutton?url=http%3A%2F%2Fmydomain.com%2F&size=standard&count=true&annotation=inline&hl=en-US&jsh=m%3B%2F_%2Fapps-static%2F_%2Fjs%2Fwidget%2F__features__%2Frt%3Dj%2Fver%3Dt6mt7PFQYRQ.en_GB.%2Fsv%3D1%2Fam%3D!agWx4Vf_ACSIFA91ZQ%2Fd%3D1%2F#id=I1_1323174311773&parent=http%3A%2F%2Fmydomain.com&rpctoken=352111652&_methods=onPlusOne%2C_ready%2C_close%2C_open%2C_resizeMe. Domains, protocols and ports must match. 

Google网站pipe理员build议的代码是否不安全? 还是我做错了什么?

这是社交插件常见的警告。 Twitter和Facebook插件通常也会引发这个警告。 你可以放心地忽略它。
