如何通过添加其他参数来重定向传入的 URL 请求 [英] How to redirect incoming URL requests by adding additional parameters

问题描述

问题:我的服务器应用程序收到一个传入的 HTTP 请求.请求是这样的:http://example.com?id=abc.我需要解析这个请求，修补额外的 URL 参数并调用一个托管的 html 文件.所以:

Problem: I get an incoming HTTP request to my server application. The request is something like this : http://example.com?id=abc. I need to parse this request, patch additional URL parameters and call a hosted html file. So:

http://example.com?id=abc => http://example.com:8080/temp.html?id=abc&name=cdf.

所以客户端应该看到 temp.html

So the client should see temp.html

代码如下:

function onRequest(request,response) {
if(request.method =='GET') {
        sys.debug("in get");
        var pathName = url.parse(request.url).pathname;
        sys.debug("Get PathName" + pathName + ":" + request.url);
        var myidArr = request.url.split("=");
        var myid = myidArr[1];
        //Call the redirect function
        redirectUrl(myid);
}
http.createServer(onRequest).listen(8888);

function redirectUrl(myid) {
var temp='';
    var options = {
      host: 'localhost',
      port: 8080,
      path: '/temp.html?id=' + myid + '&name=cdf',
      method: 'GET'
    };
  var req = http.request(options, function(res) {
    console.log('STATUS: ' + res.statusCode);
    console.log('HEADERS: ' + JSON.stringify(res.headers));
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
      temp = temp.concat(chunk);
    });
    res.on('end', function(){
        return temp;
      });
    });
  req.end();
  return temp;
}

尽管这是解决此问题的非常愚蠢的方法，但我确实在 res.end() 回调中看到了响应.如何将此传播到父调用函数 onRequest ?

Even though this is a really stupid way of going about this issue, I do see the response in the res.end() callback. How to propagate this to the parent calling function onRequest ?

是否有一种更简单的方法可以仅使用 node 来做到这一点?我知道有一些方法可以提供静态 html 文件.但是，我需要将 URL 参数传递给 temp.html - 所以我不确定如何执行此操作.

Is there a simpler way of doing this just using node ? I know that there are ways to serve static html files. However, I need to pass URL parameters to temp.html - so I'm not sure how to do this.

推荐答案

只是想知道更简单的重定向是否能达到目的:

Just wondering if a simpler redirect would serve the purpose:

  function onRequest(request,response) {
    if(request.method =='GET') {
       sys.debug("in get");
       var pathName = url.parse(request.url).pathname;
       sys.debug("Get PathName" + pathName + ":" + request.url);
       var myidArr = request.url.split("=");
       var myid = myidArr[1];
       var path = 'http://localhost:8080/temp.html?id=' + myid + '&name=cdf';
       response.writeHead(302, {'Location': path});
       response.end();
    }
