批改本地host文件来减速拜访github.
如何获取在中国的github代理ip地址?
我找到了这个网站: http://ping.chinaz.com/github...
具体思路就是和下面网站一样，循环申请接口获取各地机房的提早，而后比拟出最低提早的机房，拿到ip, 再去批改本地Host文件， go.
获取申请接口
到这个网站 http://ping.chinaz.com/github... 很快就能找到类似点。得出接口如下:
get http://ping.chinaz.com/iframe.ashx其中，最要害的是guid, 其余参数照抄即可。
对于guid, 右键源代码，发现guid全在id为speedlist的元素下。
通过以下代码获取所有机房的guid
var a = Array.from($0.children).map(v => v.getAttribute('id'))copy(a)最终的数据
