javascript - 客户端http请求打开特定页面问题

Question

我正在尝试发出 http 请求并在浏览器中打开特定页面。我已经尝试了几个软件包，例如 npm opn、npm open、openurl 但我无法达到预期的目标。这就是我正在尝试的:

服务器.js

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var http = require('http');
var fs = require('fs');

var urlencodedParser = bodyParser.urlencoded({ extended: false })

app.use(express.static('public'));

app.get('/index.html', function (req, res) {
   res.sendFile( __dirname + "/" + "index.html" );
})

app.post('/process_post', urlencodedParser, function (req, res) {

   response = {
      fname:req.body.fname,
      surname:req.body.surname,
      age:req.body.age,
      phone:req.body.phone,
      city:req.body.phone,
      email:req.body.email,
      country:req.body.country,
      postal_code:req.body.postal_code,
      password:req.body.password
   };
   console.log(response);
   res.end(JSON.stringify(response));

   var exportJson= JSON.stringify(response);

   fs.writeFile("input.txt", exportJson, function(err) {
    if(err) {
        return console.log(err);
    }
});

}) 

var server = app.listen(8081, function () {
   var host = server.address().address
   var port = server.address().port

   console.log("Listening at http://%s:%s", host, port)

})

客户端.js

var http = require('http');
var opn=require('opn');

// Options to be used by request 
var options = {
   host: '127.0.0.1',
   port: '8081',
   path: '/index.html'  
};

//opn("https://google.pt");
 var callback = function(response){
   // Continuously update stream with data
   var body = '';
   response.on('data', function(data) {
      body += data;
   });

   response.on('end', function() {
      console.log(body);
   });
}
var req = http.request(options, callback);
req.end();

编辑:

我需要通过连接到服务器/本地主机的客户端文件打开浏览器(页面是一个表单)。使用像 opn 这样的 npms 打开只会打开文档，例如:

opn(__dirname + "/" + "index.html"); //this line in the client.js

我想要这样的东西:

var req = http.request(options, callback);
opn(options.path);//with this line, when running the client.js (with the server on), the program opens another command prompt...
req.end();

Answer 1

opn(options.path); 不起作用，因为您应该使用完整路径调用 opn ，即 opn('http://127.0.0.1 :8081/index.html')
