Question

fetch('https://vanishingdante.github.io/gh-pages-blog-api/2017/02/11/bye-world')
  .then(resp => resp.json())
  .then(json => console.log(json))

我试图从我的gh页面获取我的json数据（gh-pages'Access-Control-Allow-Origin是*）

我得到的是：

what code I use and what I get

我检查了Chrome的开发工具中的网络面板：

network panel in Chrome's devtool

https请求被浏览器取消，我的提取被视为http请求。

为什么以及如何解决这个问题

curl https://vanishingdante.github.io/gh-pages-blog-api/2017/02/11/bye-world -i

将获得：

Answer 1

对https://vanishingdante.github.io/gh-pages-blog-api/2017/02/11/bye-world的请求会生成301（＆＃34;永久移动＆＃34; ）到http://vanishingdante.github.io/gh-pages-blog-api/2017/02/11/bye-world/，这会导致您的问题。

在this blog post中，它注意到如果您的网站在2016年6月15日之前已经存在，则需要在网站设置中手动启用HTTPS支持。

浏览器取消HTTPS，我的请求被视为HTTP requeset
