从请求返回结果值

Question

我想返回从“ JSON.stringify（result））”获得的结果 我做了一个请求，这返回了一些数据。 我试图返回“结果结束后，但我有错误。 我该如何实现我的代码以将其返回？！

谢谢

var r = function requete(val) {

  const xml = `----------`;

  //MES REQUIRES
  var https = require("https");
  var fs = require("fs");
  var parseString = require("xml2js").parseString;

  var options = {
    hostname: "----------",
    path: "------------",
    method: "POST",
    headers: {
      "Content-Type": "text/xml; charset=utf-8",
      "Content-Length": xml.length
    }
  };  
//My request
  var req = https.request(options, res => {
    console.log(`STATUS: ${res.statusCode}`);
    console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
    res.setEncoding("utf8");
    var data=''
    res.on("data", chunk => {
      data+=chunk;
      parseString(data, function(err, result) {
        console.log(".............................");

       console.log(JSON.stringify(result));

//=====>>>>>>i want to return this "result"

        });

    });

    res.on("end", () => {
      console.log("No more data in response.");

    });
  });

  req.on("error", e => {
    console.log(`problem with request: ${e.message}`);

  });
  // write data to request body
  req.write(xml); // xml would have been set somewhere to a complete xml document in the form of a string
  req.end();

};
