为Hexo博客启用HTTPS协议

为Hexo博客启用HTTPS协议

前言

随着HTTP协议的越来越不被待见，以及各大浏览器厂商对于HTTP采取的打压措施，举个栗子，当我在服务器上同时启用HTTP以及HTTPS监听的时候，访问HTTP服务的时候，就会被重定向到HTTPS的链接上，但是HTTPS的链接又不存在，然后就会出现如下报错：

话不多说，我们直接上代码 server.js：
server.js文件位于博客目录/node_modules/hexo-server/lib/

注意事项

  • 需要添加2个新的引用，分别是https和fs，https用来创建https Server，fs用来读取证书信息：
    1
    2
    const https = require("https");
    const fs = require("fs");
  • 添加一个新的变量，options，用来存放证书：
    1
    2
    3
    4
    const options = {
      key:fs.readFileSync("$PWD/5792506_www.majun.fun.key"),
      cert:fs.readFileSync("$PWD/5792506_www.majun.fun.pem")
    };
  • 最后我们只需要创建一个https的服务器就可以了：
    1
    https.createServer(options, app).listen(443);
