发送JSON到地址不同然后res

Question

我创建了一个小型快递模块。这个atm听url在localhost上运行但是计划收听triggerURL:ListenPort并从外部服务运行。

clientA：服务器应该从网页（triggerURL）接收调用，并作为响应将JSON对象发送到unity_url。

clientB：一个团结的应用程序将打开听tazxswpoi。

问题是，虽然将JSON发送到res并返回clientA没有问题，但我不确定如何使用SendingPort和resp创建新的可写流并将json发送到clientB。

writable

Answer 1

您需要向目标网址发送请求。例如（使用

var express = require('express');
var fs = require('fs');
var app = express();

var triggerURL = ''; //i'll send an http request to this adress to trigger the action from server


var JSON = {
    item: "seeds",
    Answers: "5",
    richText: "<b>How can you reduce crop toxicity by turning plants upside down?</b><br/>Idea:<br/> Upside-down gardening is a hanging vegetable garden being the suspension of soil and seedlings of a kitchen garden to stop <b>pests</b> and blight,and eliminate the typical gardening tasks of tilling, weeding, and staking plants."
}
var port = process.env.PORT || 3000;
var ListenPort = '8086'; // my port to recieve triggers
var SendingPort = '4046'; // which unity will listen to
var unity_url ='185.158.123.54:'+SendingPort; //fake IP, just for the example

//triggerURL
app.get('/', function(req,res){
    var resp = JSON.stringify(JSON);
    var writable = fs.createWriteStream();

    //res.json(JSON); //instead i wanna send it to unity_url;
});


//app.listen(ListenPort);
app.listen(port);

）。
