我找到了req。协议工作时，我使用express(没有测试，但我怀疑它工作)。使用当前节点0.10.22和express 3.4.3

app.use(function(req,res,next) {
  if (!/https/.test(req.protocol)){
     res.redirect("https://" + req.headers.host + req.url);
  } else {
     return next();
  } 
});

你可以实例化2个Node.js服务器——一个用于HTTP，一个用于HTTPS

还可以定义两台服务器都将执行的设置函数，这样就不必编写大量重复的代码。

下面是我的方法:(使用retify .js，但应该适用于express.js，或node本身)

如果你的节点应用程序安装在IIS上，你可以在web.config中这样做

<configuration>
    <system.webServer>

        <!-- indicates that the hello.js file is a node.js application 
    to be handled by the iisnode module -->

        <handlers>
            <add name="iisnode" path="src/index.js" verb="*" modules="iisnode" />
        </handlers>

        <!-- use URL rewriting to redirect the entire branch of the URL namespace
    to hello.js node.js application; for example, the following URLs will 
    all be handled by hello.js:
    
        http://localhost/node/express/myapp/foo
        http://localhost/node/express/myapp/bar
        -->
        <rewrite>
            <rules>
                <rule name="HTTPS force" enabled="true" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions>
                        <add input="{HTTPS}" pattern="^OFF$" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" />
                </rule>
                <rule name="sendToNode">
                    <match url="/*" />
                    <action type="Rewrite" url="src/index.js" />
                </rule>
            </rules>
        </rewrite>

        <security>
            <requestFiltering>
                <hiddenSegments>
                    <add segment="node_modules" />
                </hiddenSegments>
            </requestFiltering>
        </security>

    </system.webServer>
</configuration>

这个脚本在加载页面时保存URL页面，并检查地址是https还是http。如果是http，脚本会自动将您重定向到相同的https页面

(function(){
  var link = window.location.href;
  if(link[4] != "s"){
    var clink = "";
    for (let i = 4; i < link.length; i++) {
      clink += link[i];
    }
    window.location.href = "https" + clink;
  }
})();

这个想法是检查传入的请求是否使用https，如果是，就不要再次重定向到https，而是像往常一样继续。否则，如果它是http，则通过附加https重定向它。

app.use (function (req, res, next) {
  if (req.secure) {
          next();
  } else {
          res.redirect('https://' + req.headers.host + req.url);
  }
});

你可以使用“net”模块在同一个端口上监听HTTP和HTTPS

var https = require('https');
var http = require('http');
var fs = require('fs');

var net=require('net');
var handle=net.createServer().listen(8000)

var options = {
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
};

https.createServer(options, function (req, res) {
  res.writeHead(200);
  res.end("hello world\n");
}).listen(handle);

http.createServer(function(req,res){
  res.writeHead(200);
  res.end("hello world\n");
}).listen(handle)
